Development of Novel Micellar-Enhanced High-Throughput Microwell Spectrofluorimetric Method for Quantification of Lorlatinib: Application to In Vitro Drug Release and Analysis of Urine Samples. Pharmaceuticals (Basel) 2023; 16:1260. [PMID: 37765067 PMCID: PMC10535339 DOI: 10.3390/ph16091260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 09/01/2023] [Accepted: 09/04/2023] [Indexed: 09/29/2023] Open
Abstract
Lorlatinib (LOR) is a third-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor drug. The Food and Drug Administration (FDA) has granted an approval for the use of LOR as a first therapeutic intervention for individuals diagnosed with ALK-positive metastatic and advanced non-small-cell lung cancer (NSCLC). The present study outlines, for the first time, the development and validation of an innovative microwell-based spectrofluorimetric (MW-SFL) method for the quantification of LOR. The proposed method involved the enhancement of the weak native fluorescence of LOR by its micellization into the sodium lauryl sulfate (SLS) micelles. The procedures of the method were conducted in white opaque plates with 96 microwells, and the enhanced fluorescence signals were measured by a fluorescence plate reader at 405 nm after excitation at 310 nm. The measured relative fluorescence intensity (RFI) had a linear relationship with LOR concentrations in the range of 60-1600 ng mL-1. The limit of detection (LOD) and the limit of quantification (LOQ) were found to be 19 and 56 ng mL-1, respectively. The method's accuracy and precision were assessed using a recovery study; the recovery values ranged from 99.98% to 101.40%, accompanied by relative standard deviation (RSD) values of 0.42% to 1.59%. The proposed MW-SFL method combined the advantages of the intrinsically high sensitivity of the spectrofluorimetric measurement and the excellent throughput of the microwell-based approach. The results proved the method is effective in the determination of LOR in its pharmaceutical tablets, tablet dissolution testing, as well as in spiked urine with a high degree of precision and accuracy. The MW-SFL method is notable for its simple procedures and utilization of water as a solvent, as well as minimal quantities of sample solutions. These features align with its ecofriendly approach to green chemistry principles. These advantages gave the proposed MW-SFL method a high potential value for the determination of LOR in clinical and quality control laboratories.

Abstract
Background and Objectives: This study presents the development and validation of the 96-microwell-based spectrofluorimetric (MW-SFL) and high performance liquid chromatography (HPLC) with fluorescence detection (HPLC-FD) methods for the quantitation of alectinib (ALC) in its bulk powder form and in urine samples. Materials and Methods: The MW-SFL was based on the enhancement of the native fluorescence of ALC by the formation of micelles with the surfactant cremophor RH 40 (Cr RH 40) in aqueous media. The MW-SFL was executed in a 96-microwell plate and the relative fluorescence intensity (RFI) was recorded by utilizing a fluorescence plate reader at 450 nm after excitation at 280 nm. The HPLC-FD involved the chromatographic separation of ALC and ponatinib (PTB), as an internal standard (IS), on a C18 column and a mobile phase composed of methanol:potassium dihydrogen phosphate pH 7 (80:20, v/v) at a flow rate of 2 mL min–1. The eluted ALC and PTB were detected by utilizing a fluorescence detector set at 365 nm for excitation and 450 nm for emission. Results: Validation of the MW-SFL and HPLC-FD analytical methods was carried out in accordance with the recommendations issued by the International Council for Harmonization (ICH) for the process of validating analytical procedures. Both methods were efficaciously applied for ALC quantitation in its bulk form as well as in spiked urine; the mean recovery values were ≥86.90 and 95.45% for the MW-SFL and HPLC-FD methods, respectively. Conclusions: Both methodologies are valuable for routine use in quality control (QC) laboratories for determination of ALC in pure powder form and in human urine samples.

Abstract
Erdafitinib is the first treatment targeting susceptible fibroblast growth factor receptor (FGFR) genetic alterations in patients with locally advanced or metastatic urothelial carcinoma. A simple and precise spectrofluorimetric method was developed for its determination depending on fluorescence enhancement using Kolliphor RH 40 micellar medium at pH 10. The fluorescence intensity was measured at 495 nm after excitation at 410 nm. Different experimental parameters affecting the fluorescence intensity, including type of organized medium, diluting solvent, buffer type and pH were studied during optimization phase. Validation according to ICH Q2(R1) guidance was fully fulfilled. The method was linear over the range of 50 - 800 ng/mL. The lower limit of detection (LOD) and lower limit of quantitation (LOQ) were 14.36 and 43.50 ng/mL, respectively. The relative standard deviation values of intraday and interday precisions were less than 1.93 %. The proposed method was successfully applied to laboratory-prepared tablets. Furthermore, the high sensitivity of the method allowed its application on spiked human plasma samples with a high percent of recovery. The greenness of the method was investigated as an Eco-friendly alternative for erdafitinib determination with minimal organic solvent consumption.

Abstract
HYPOTHESIS The free energies associated with adsorption/desorption of individual surfactants from micelles and the fusion/scission of long micelles can be used to estimate the rate constants for micellar kinetics as functions of surfactant and salt concentration. EXPERIMENTS We compute the escape free energies △Gesc of surfactant from micelles and the scission free energies △Gsciss of long micelles from coarse-grained molecular dynamics simulations coupled with umbrella sampling, for micelles of both sodium dodecylsulfate (SDS) in sodium chloride (NaCl) and cetyltrimethylammonium chloride (CTAC) in sodium salicylate (NaSal). FINDINGS For spherical micelles, △Gesc values have maxima at certain aggregation numbers, and at salt-to-surfactant molar concentration ratios R near unity, consistent with experiments. For cylindrical micelles, SDS/NaCl shows a minimum, and CTAC/NaSal a maximum in △Gesc, both at R ~ 0.7, while △Gsciss of CTAC micelles also peaks at around R ~ 0.7 and that of SDS micelles increases monotonically with R. We explain the non-monotonic dependence of escape and scission free energies on R by a combination of electrostatic screening and the decrease of micelle radius with increasing R. Transitions from predominantly spherical to cylindrical micelles, and between adsorption/desorption and fusion/scission kinetics with changing salt concentration can be inferred from the free energies for CTAC/NaSal.

Abstract
Two simple and sensitive spectrofluorimetric methods were developed and validated for determination of diphenhydramine. The use of sodium dodecyl sulfate surfactant at pH 7 enhances the fluorescence intensity of diphenhydramine at 286 nm (method I) enabling its nanodetermination in biological samples with mean per cent recovery ± SD of 100.33 ± 1.519. Method I was validated according to ICH-Q2R1 guidelines and was successfully applied for determination of diphenhydramine in pharmaceutical dosage form and spiked human plasma in the concentration ranges 0.1-4.0 μg/mL and 0.2-1.0 μg/mL, respectively. Method I acted as a basis for the development of a first derivative synchronous spectrofluorimetry (method II) for simultaneous analysis of diphenhydramine and naproxen using a zero-crossing approach. Method II determines both drugs with linearity ranges of 0.05-3.0 μg/mL and 0.1-0.9 μg/mL for diphenhydramine and naproxen, respectively. The developed method was applied for the simultaneous determination of both drugs in their laboratory-prepared mixtures containing all expected excipients. Method II determines both drugs with a mean percent recovery ± SD of 100.56 ± 0.891 and 100.20 ± 1.125 for diphenhydramine and naproxen, respectively. The method was statistically compared with a reported method using Student's t- and F- tests, and no significant differences were observed.

Experimental and computational evaluation of kolliphor RH 40 as a new fluorescence enhancer in development of a micellar-based spectrofluorimetric method for determination of lapatinib in tablets and urine. PLoS One 2020; 15:e0239918.

Abstract
This study describes, for the first time, the experimental and computational investigations for evaluation of kolliphor RH 40 as a fluorescence enhancer surfactant in development of a spectrofluorimetric method for determination of lapatinib (LAP), a tyrosine kinase-inhibitor drug approved for targeted therapy of breast cancer. The investigations involved the ability of kolliphor RH 40 to form micelles with LAP and its enhancing effect on the weak native fluorescence of LAP at 420 nm after its excitation at 292 nm. Different variables were experimentally investigated: types of organized media, diluting solvent, buffer type and its pH value. The optimum values of the most influencing variables on the interaction of kolliphor RH 40 with LAP were refined by the computational response surface methodology (RSM). Under the optimized conditions, it was found that kolliphor RH 40 forms micelles with LAP, and its fluorescence enhancing ability was higher than other surfactants tested by ~ 10-folds. This micellar-enhanced effect of kolliphor RH 40 was employed in the development of a new sensitive spectrofluorimetric method for the accurate determination of LAP. The method was validated according to the guidelines of the International Conference on Harmonization (ICH) for validation of analytical procedures. The relative fluorescence intensity (RFI) was in excellent linear relationship (correlation coefficient was 0.998) with the LAP concentrations in the range of 50–1000 ng/mL. The method limit of detection (LOD) was 27.31 ng/mL and its accuracy was ≥ 99.82%. The method was successfully applied to the determination of LAP in its pharmaceutical tablets, tablets dissolution testing and content uniformity. The method application was extended to the determination of LAP in urine samples with an accuracy of 99.82 ± 3.45%. The method is considered as an eco-friendly green approach and more efficient alternative method to the existing analytical methodologies for determination of LAP.

Abstract
Simeprevir (SMV) is commonly co-administered with ledipasvir (LDS) and sofosbuvir (SOF) as an effective combination regimen for treatment naive hepatitis C virus infected patients. In the present study, two spectrofluorimetric approaches were combined together for the development of highly sensitive, rapid, simple and accurate method for simultaneous quantification of SMV and LDS. The native fluorescence intensity values of SMV and LDS were enhanced by the addition of Tween-80 micellar system, while second derivative of the synchronous fluorescence intensity of the drugs at Δλ = 120 nm enabled the determination of both drug concomitantly. Different experimental parameters affecting the synchronous fluorescence of the cited drugs were carefully evaluated for their optimization. The peak amplitudes of the second derivative synchronous fluorimetry were measured at 429 nm for SMV and at 417 nm for LDS. The fluorescence-concentration plots were rectilinear over the range of 60-1500 and 36-540 ng mL-1 with lower detection limits of 9.0 and 6.0 ng mL-1 and quantification limits of 27.0 and 17.0 ng mL-1 for SMV and LDS respectively. The method was successfully applied for the determination of both drugs in their pure forms as well as their pharmaceutical products and human plasma without any significant interference. Statistical comparison with the reported method revealed excellent accuracy and precision of the proposed method.

Abstract
The adsorption of methanol, ethanol and propan-1-ol at the solution-air and solid-solution interfaces, their aggregation in the aqueous media as well as wetting properties regarding their applications as additives or co-surfactants in the surfactants aqueous solution were discussed based on the literature data. Mutual influence of alcohols and surfactants on the solution-air and solid-solution interface tension was considered. For this purpose there were used different methods allowing to describe or predict changes of water surface tension as a function of alcohols concentration. These, in turn, as a function of alcohol and/or surfactant concentration were also analyzed by means of the methods applied for prediction of surface tension of aqueous solution of the classical surfactants mixture. The same considerations related to the behaviour of alcohol and surfactant at the solid-solution and solution-air interfaces were made. To explain the behaviour of alcohols and surfactants mixture at the solution-air and solid-solution interfaces the components and parameters of water, alcohols, surfactants and solids surface tension as well as the Gibbs free energy changes during the adsorption process were taken into account. It was proved that wettability of some solids can be predicted based on alcohol and surfactants adsorption as well as surface tension components and parameters. As follows the mutual influence of alcohol and surfactant on their adsorption at the solution-air and solid-solution interfaces as well as on the wetting properties at the alcohol concentration from zero to its critical aggregation concentration (CAC) is different from that at its concentration higher than CAC.

Abstract
A fast, low-cost, sensitive, and selective spectrofluorimetric method for the determination of ledipasvir was developed and validated. The method is based on an enhancement in the native fluorescence intensity of ledipasvir by 500% of its original value by the formation of hydrogen bonds between the cited drug and Tween-20 in the micellar system (pH = 5.0). All fluorescence measurements were carried out at 425 nm and 340 nm for emission and excitation wavelengths, respectively. A linear relationship between the concentration of ledipasvir and the observed fluorescence intensity was achieved in the range of 0.1-2.0 μg ml-1 with 0.028, 0.084 μg ml-1 , for detection and quantitation limits, respectively. The acquired selectivity and sensitivity using the proposed method facilitate the analysis of ledipasvir in spiked human plasma with sufficient percentage recovery (95.36-99.30%). The proposed method was developed and validated according to International Council for Harmonisation (ICH) guidelines. Moreover, the cited drug was successfully determined in its pharmaceutical dosage form using the proposed method. In addition, the validity of the proposed results was statistically confirmed using Student's t-test, variance ratio F-test, and interval hypothesis test.

[PMID: 31849179 DOI: 10.1002/bio.3739] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 10/24/2019] [Accepted: 10/26/2019] [Indexed: 01/26/2023]
Abstract
Simeprevir (SPV) is a powerful antihepatitis C virus agent that was newly introduced into the pharmaceutical market. We here established and validated an easy, simple, and sensitive spectrofluorimetric method for its estimation at λem 427 nm (λex 337 nm). The suggested procedure was based on two times enhancement in the original emission of SPV through modifying its microenvironment in buffered aqueous solution by adding Triton X-100. The relationship between the concentration of SPV and the observed fluorescence intensity was linear in the range 0.06-1.0 μg ml-1 with a correlation coefficient of 0.9997. The limits of detection and quantitation were 21 and 64 ng ml-1 , respectively. The present method was effectively applied to quantify SPV content in pharmaceutical tablets and human plasma spiked with the drug with no interference from tablet excipients or plasma components.

Abstract
A highly sensitive and accurate novel response surface methodology (RSM)-assisted micellar enhanced synchronous spectrofluorimetric method was developed and validated for determination of vandetanib (VDB) in tablets, human plasma and urine. The method relied on enhancement of the fluorescence behavior of VDB in polyoxyethylene hydrogenated castor oil 40 (HCO 40) micellar medium and measuring the fluorescence using synchronous scan approach (Δλ = 50 nm). Key factors affecting VDB fluorescence were optimized by RSM using Box-Behnken design. These factors were the type and volume of surfactant and pH of the buffer medium. Under the optimum conditions, the fluorescence-concentration plot was linear over the range 40-600 ng mL-1; the limits of detection and quantification were 5.22 and 15.82 ng mL-1, respectively. The suggested method was successfully applied to the analysis of laboratory-prepared tablets, spiked human plasma and urine samples. The results were statistically compared with those acquired by a pre-validated liquid chromatography-tandem mass spectrometric reference method and the results obtained from both methods were found to be in good agreement.

Abstract
This study is concerned with two sensitive, fast and reproducible approaches; namely, second-derivative synchronous fluorimetry (method I) and reversed phase high-performance liquid chromatography with fluorimetric detection (method II) for synchronized evaluation of losartan (LOS) and amlodipine besylate (AML). Method I is based on measuring second-derivative synchronous fluorescence spectra of LOS and AML at Δλ = 80 nm in water. The experimental factors influencing the synchronous fluorescence of the considered compounds were sensibly adjusted. The chromatographic analysis was executed on a Nucleodur MN-C18 column of dimensions; 250 × 4.6 mm i.d. and 5 µm particle size). The fluorimetric detection was time-programmed at λem = 440 nm for AML (0.0-7.5 min) and at λem = 400 nm for LOS (7.5-10 min) after excitation at λex = 245 nm. The mobile phase is a blend of acetonitrile with 0.02 M phosphate buffer in a proportion of 45 : 55, pH 4.0, pumped using a flow rate of 1 ml min-1. The calibration plots were established to be 0.1-4.0 µg ml-1 for both drugs in method I and 0.05-4.0 µg ml-1 for both drugs in method II. The study was extended to the evaluation of the two drugs in their co-formulated tablets.

Abstract
Two new, simple, selective, and highly sensitive spectrofluorimetric methods were developed and validated for the determination of the antiepileptic drug; retigabine (RTG). The first method (Method-I) depends on enhancement of the weak native fluorescence of RTG via the use of an organized medium; sodium dodecyl sulphate (SDS) in acetate buffer (pH 3.74). The second method (Method-II) depends on the enhancement of RTG weak native fluorescence through complexation with a macromolecule; beta cyclodextrin (β-CD) in phosphate buffer (pH 3.20). A full study of different experimental parameters influencing the fluorescence intensity was carried out. In addition, a thorough investigation of the fluorescence quantum yield, fluorophore brightness and mechanism of fluorescence enhancement was performed. A seven-fold improvement in the fluorescence intensity was brought by the first method, whereas a six and half-fold enhancement of the fluorescence intensity was obtained by the second one. Linearity was achieved over wide ranges (0.05-12.5 μg mL-1) and (0.05-15 μg mL-1) with low limits of detection (LOD) of 10.6 and 14.3 ng mL-1, and limits of quantification (LOQ) of 32.0 and 43.2 ng mL-1 for (Method-I) and (Method-II), respectively. The proposed methods were validated according to ICH and US-FDA guidelines. The applicability of the proposed methods was tested for determination of RTG in its pharmaceutical dosage forms, and to study the stability of RTG under different stress conditions according to ICH guidelines including alkaline, acidic, oxidative, thermal, and photolytic stress conditions. Moreover, the high sensitivity achieved by the proposed methods permitted the determination and detection of RTG in both spiked and real rabbit plasma samples utilizing a simple protein precipitation step followed by liquid-liquid extraction method. Percentage recoveries from rabbit plasma samples were within the acceptable limits; (93.47-104.74%) and (91.33-105.70%) for (Method-I) and (Method-II), respectively.

Abstract
A micelle enhanced spectrofluorimetric method was developed for determination of Omarigliptin (OMG) based on its native fluorescence behavior. The interaction of OMG with surfactants and macromolecules was studied. In aqueous solution, the relative fluorescence intensity (RFI) of OMG was enhanced by 24% in the presence of Tween 80 at pH 3.5. The optimal conditions for the micelle enhanced fluorescence were attained by Minitab® program using Plackett-Burman factorial design. Pareto chart, contour plots and surface plots were used to exclude the insignificant variables and optimize the significant factors. The spectrofluorimeter was operated under synchronous mode using ∆λ = 30 nm and recording the RFI of the intense narrow band at 267 nm for OMG in 0.5% w/v Tween 80 + 0.2 M acetate buffer (pH 3.5) system using water as diluent. Using synchronous scan mode offered many advantages including considerable reduction of spectral overlap and enhanced linearity of the calibrators. Validation parameters were satisfied over the concentration range 0.1-2 μg/ml. The developed method was the first analytical procedure for OMG assay in Marizev® tablets. Moreover, content uniformity testing and in vitro drug release of tablets were performed.

Abstract
An easy, quick, simple and accurate spectrofluorimetric method was recognized and validated for evaluation of sorafenib (SOR) in pure form and biologically in plasma. Cremophor RH 40 (Cr RH 40) used for enhancing the fluorescence activity of SOR in phosphate buffer (pH 7). Cr RH 40 improved the native fluorescence of SOR remarkably in water. The fluorescence spectrum of SOR was observed at 405 nm after excitation at 265 nm. The linearity appeared to be in the range of 5 to 600 ng ml-1 for pure and from 9 to 500 ng ml-1 for plasma using the protein precipitation (ppt) method while from 10 to 500 ng ml-1 for plasma using liquid-liquid extraction method. The precisions and the accuracy of the estimated method gave satisfactory results. The recommended method was effectively applied for determination of SOR in human plasma with high recovery values. The results of some compounds that are possibly found in plasma were studied. The proposed method was also focused on real volunteers and a drug dissolution test.

Abstract
An impressively simple and precise spectrofluorimetric procedure was established and validated for ponatinib (PTB) quantitation in biological fluids such as human plasma and human urine. This method depends on examining the fluorescence characteristics of PTB in a micellar system of Cremophor RH 40 (Cr RH 40). Cr RH 40 enhanced the intrinsic fluorescence of PTB distinctly in aqueous water. The fluorescence spectra of PTB was recorded at 457 nm following its excitation at 305 nm. Maximum fluorescence intensity was attained by addition of 0.7 mL of Cr RH 40 and one mL of phosphate buffer to PTB aliquots and then dilution with distilled water. There is a linear relationship between the fluorescence intensity of PTB and its concentration over the range 5–120 ngmL−1, with limit of detection and limit of quantification equal to 0.905 ngmL−1 and 2.742 ngmL−1, respectively. The accuracy and the precisions of the proposed method were checked and gave adequate results. The adopted method was applied with a great success for PTB quantitation in different biological matrices (spiked human plasma and urine) giving high recovery values.

Abstract
Rapid, simple and sensitive two spectrofluorimetric methods have been developed for determination of Felodipine (FLD) and Nimodipine (NDP). The first method is based on measuring the native fluorescence of either Felodipine or Nimodipine at 426 nm after excitation at 385 nm. The fluorescence intensity-concentration plots of Felodipine and Nimodipine were rectilinear over the concentration ranges (0.2-3.0) and (0.5-4.0) μg ml(-1), respectively. The second method is based on measuring the fluorescence intensity of the studied drugs in micellar media (0.3% Tween-80) at λex=385 nm and λem=423 nm. In the presence of 0.3% Tween-80, about 1.6-fold and 2.1-fold enhancement can be achieved in the relative fluorescence intensity (RFI) of Felodipine and Nimodipine, respectively. The fluorescence intensity-concentration plots of Felodipine and Nimodipine with Tween-80 were rectilinear over the concentration ranges (0.05-4.0) and (0.1-4.0) μg ml(-1), respectively with determination coefficients (r(2)) of 0.9981 and 0.9990, and limit of quantitation of 0.05 and 0.027μg ml(-1) for FLD and NDP, respectively. The proposed methods were validated according to ICH guidelines and have been successfully applied to the analysis of these drugs in their commercial tablets with high accuracy (97.6-98.8±0.50-1.42%, n=5). The high sensitivity of micellar method permits its application for determination of the cited drugs in spiked human plasma with % recovery (91.9-106.6±0.66-1.7%, n=6).

Two validated spectrofluorometric methods for determination of gemifloxacin mesylate in tablets and human plasma. Int J Anal Chem 2013; 2013:137279.

Abstract
Two new, sensitive, and selective spectrofluorometric methods were developed for the determination of gemifloxacin mesylate (GFX) in tablets and spiked human plasma. Method A was based on measurement of the enhanced fluorescence spectral behaviour of GFX in a sodium dodecyl sulphate (SDS) micellar system. In aqueous solution of acetate buffer pH 5.5, the fluorescence intensity of GFX was greatly enhanced about tenfold in the presence of SDS. The fluorescence intensity was measured at 402 nm after excitation at 274 nm. Method B was based on Hantzsch condensation reaction between the primary amino group of GFX with acetylacetone and formaldehyde in acetate buffer of pH 3.5 yielding a highly yellow fluorescent derivative. The reaction of GFX with acetylacetone-formaldehyde system solution resulted in bathochromic shift of both emission (476 nm) and excitation (420 nm) wavelengths. The fluorescence intensity was directly proportional to the concentration over the range 10–1000 ng/ml and 100–2000 ng/ml for method A and B, respectively. The proposed methods were applied successfully for determination of GFX in its tablets and spiked plasma. Therefore, these methods can be considered of real interest for reliable and practical quality control analysis of GFX.

Abstract
Abstract
The micelle solutions of sodium dodecyl sulphate (NaDS) modified by simultaneously presence of different aliphatic alcohols and an inorganic salt have been quantitatively characterized by the values of critical micelle concentrations, the degrees of counter-ion binding and electrostatic potentials of surface. The obtained characteristics of hybrid micelles and the coefficients of modifier distribution between aqueous solution and micellar pseudophase were used to develop a conceptual retention model in micellar liquid chromatography (MLC). The new retention model takes into account the microenvironment changes of an analyte when it goes from the hybrid micellar eluent to a modified surface of alkyl-bounded sorbent.

Abstract
Abstract
Micelles are known to be dynamic entities, rapidly breaking and reforming continuously. Micellar dynamics can be manipulated by the addition of non-ionic or oppositely charged cosurfactant to a sodium dodecyl sulfate solution. Using filtration through nanoporous membranes we have shown that sodium dodecyl sulfate micellar solutions are not only made up of micelles and monomers, but also contain a high concentration of sub-micellar aggregates. The concentration of sub-micellar aggregates decreases as the micellar stability increases. We have investigated the role of micellar stability and sub-micellar aggregates in cleaning of fabrics and hard surfaces such as porcelain dishes. After careful observation, it was determined that more stable micelles and lower concentrations of sub-micellar aggregates lead to more efficient detergency. In summary, it is desirable to have relatively stable micelles and the least number of sub-micellar aggregates for efficient detergency.
