Abstract
OBJECTIVE In vitro assessments of skin absorption of xenobiotics are essential for toxicological evaluations and bioavailability studies of cosmetic and pharmaceutical ingredients. Since skin metabolism can greatly contribute to xenobiotic absorption, experiments need to be performed with skin explants kept viable in suitable survival media. Existing protocols for non-viable skin are modified to consider those conditions. The objective was to design a survival medium used as an acceptor fluid in Franz cells for testing cutaneous penetration of hydrophilic or lipophilic molecules. Their metabolism inside skin may be investigated under the same conditions. The determining factors involved in survival mechanisms in vitro are discussed. The consequences of short-term skin preservation at 4°C were also evaluated. METHODS The metabolic activity of fresh skin samples mounted in Franz cells was studied by measurement of lactate release over 24 h in order to assess the impacts of pH, buffering, osmolality, ionic strength, initial glucose supply and the addition of ethanol or non-ionic surfactant in the acceptor part of Franz cells. CONCLUSION Survival media must maintain physiological pH (>5.5) be isotonic with skin cells (300 mOsm kg-1 ) and contain at least 0.5 g L-1 glucose. Several compositions able to preserve skin metabolism are reported. Storage of skin explants overnight at 4°C impairs skin metabolic activity. The present work provides guidelines for designing survival media according to constraints related to the scientific requirements of the experiments.

Abstract
Particle-stabilized emulsion systems have been developed to address the problematic properties of conventional surfactants. However, the nature and properties of the fine particles used in such systems remain a critical issue for stability enhancement. Herein, we describe a thermoswitchable oil-in-water (O/W) particle-stabilized emulsion that exhibits improved stability due to the addition of cellulose nanocrystals (CNCs) modified with poly[2-isopropoxy-2-oxo-1,3,2-dioxaphospholane] (PIPP), which exhibits relatively good biocompatibility and biodegradability. Various parameters, such as surface activity, concentration of particles, polarity of solvents, and temperatures, on the formation of emulsions with CNCs grafted with PIPP (CNC-g-PIPP) were investigated. Results showed that the surface activity of CNC-g-PIPP was significantly improved compared with the unmodified material. Heptane-in-water particle-stabilized emulsions with CNC-g-PIPP were stably formed, and the effect of temperature on the stability of the emulsions was characterized. CNC-g-PIPP exhibited function as an effective particulate emulsifier at 4 °C because of the strong adsorption at the oil-water interface. However, the emulsions rapidly disintegrated at 45 °C, which is above the low critical solution temperature of PIPP on CNC, as the hydrophobized CNC-g-PIPP desorbed from the oil-water interface. Based on these findings, a thermally induced reversible emulsification/demulsification was presented. The resulting switchable particle-stabilized emulsion based on CNC-g-PIPP shows promise for the ability to control the stability of an emulsion in response to temperature, which is attractive for use in biological applications.

Abstract
To predict the results of a 24-hr closed human patch test, we previously recommended the use of in vitro test with a reconstructed human epidermis (RhE) model adopted in OECD TG 439, and proposed the margin method, which includes evaluation of twice the concentration to avoid a false positive for surfactants. Therefore, in this study, we used LabCyte EPI-MODEL as a RhE model, and confirmed the reproducibility of this method using five surfactants, including benzalkonium chloride (BC), sodium lauryl sulfate (SLS), and lauryl betaine (LB), for which false negative results have previously been reported, and three different surfactants. For all surfactants, prediction of patch test results using a margin of two revealed that human tests could be performed safely, confirming the utility of the margin method. In addition, we examined the relationship with critical micellar concentration (CMC). The IC50 for cell viability in the RhE model for three types of surfactants (BC, SLS, and LB) was 2.7- to 49.7-times the CMC. Therefore, the range of concentrations in which tests were performed with the present method was within the range of concentrations with high cleansing. Furthermore, we examined the relationship between cell viability and release of the inflammatory mediator interleukin-1α (IL-1α). IL-1α release was associated with cell viability, supporting the results of the human patch test.

Abstract
A novel biocompatible water-in-oil microemulsion was developed using nonionic surfactants and was investigated as a potential enzyme delivery system for pharmaceutical applications. The system was composed of isopropyl myristate/polysorbate 80 (Tween 80)/distilled monoglycerides/water/propylene glycol (PG), had a low total surfactant concentration (8.3% w/w), and was able to incorporate approximately 3% w/w aqueous phase containing horseradish peroxidase (HRP). Structural and activity aspects of the system were studied using a variety of techniques such as dynamic light scattering (DLS), electron paramagnetic resonance (EPR), and dynamic interfacial tension. The apparent hydrodynamic diameter of the empty droplets was calculated at about 37 nm. Different enzyme concentrations, ranging from 0.01 to 1.39 μM, were used for both DLS and EPR studies to effectively determine the localization of the macromolecule in the microemulsion. According to the results, for high enzyme concentrations, a participation of HRP in the surfactant monolayer of the microemulsion is evident. The number of reverse micelles in the microemulsion was defined by a theoretical model and was used to clarify how the enzyme concentration affects the number of empty and loaded reverse micelles. To assure that the system allows the enzyme to retain its catalytic activity, an oxidative reaction catalyzed by HRP was successfully carried out with the use of the model substrate 2,2'-azino-bis[3-ethylbenzothiazoline-6-sulfonic acid]. The influence of several parameters such as temperature, pH, and PG concentration was examined to optimize the reaction conditions, and a kinetic study was conducted revealing an ordered-Bi-Bi mechanism. Values of all kinetic parameters were determined. The release of the encapsulated enzyme was studied using an adequate receiver phase, revealing the effectiveness of the proposed microemulsion not only as a microreactor but also as a carrier for therapeutic biomolecules.

Abstract
Pickering emulsions were formulated using biodegradable and biocompatible poly(lactic- co-glycolic acid) (PLGA) nanoparticles (NPs) prepared without surfactants or any other polymer than PLGA. A pharmaceutical and cosmetic oil (Miglyol) was chosen as the oil phase at a ratio of 10% w/w. These emulsions were then compared with emulsions using the same oil but formulated with well-described PLGA-poly(vinyl alcohol) (PVA) NPs, i.e., with PVA as NP stabilizers. Strikingly, the emulsions demonstrated very different structures at macroscopic, microscopic, and interfacial scales, depending on the type of NPs used. Indeed, the emulsion layer was significantly thicker when using PLGA NPs rather than PLGA-PVA NPs. This was attributed to the formation and coexistence of multiple water-in-oil-in-water (W/O/W) and simple oil-in-water (O/W) droplets, using a single step of emulsification, whereas simple O/W emulsions were obtained with PLGA-PVA NPs. The latter NPs were more hydrophilic than bare PLGA NPs because of the presence of PVA at their surface. Moreover, PLGA NPs only slightly lowered the oil/water interfacial tension whereas the decrease was more pronounced with PLGA-PVA NPs. The PVA chains at the PLGA-PVA NP surface could probably partially desorb from the NPs and adsorb at the interface, inducing the interfacial tension decrease. Finally, independent of their composition, NPs were adsorbed at the oil/water interface without influencing its rheological behavior, possibly due to their mobility at their interface. This work has direct implications in the formulation of Pickering emulsions and stresses the paramount influence of the physicochemical nature of the NP surface into the stabilization of these systems.

Abstract
Understanding the interactions of amphiphile molecules with biological membranes is very important to many practical applications. Amino acid amphiphiles are a kind of mild surfactants and have many unique performances. However, their interactions with phospholipid membranes have scarcely been studied. This work has studied the interactions of glutamic acid-based gemini amphiphile C12(Glu)2C12 and single-chain amphiphile C12Glu with the model biomembrane formed by the phospholipid 1,2-dioleoyl- sn-glycero-3-phosphocholine (DOPC). The partition coefficients of C12(Glu)2C12 and C12Glu into the DOPC vesicles were derived from the observed enthalpy curves obtained by isothermal titration calorimetry at temperatures of 25.0 and 37.0 °C, and pHs of 5.6 and 7.4, corresponding to the skin surface and human physiological conditions. The results from cryogenic transmission electron microscopy, dynamic light scattering, and zeta potential measurements show that the amphiphile molecules form different aggregates, which make the amphiphile molecules exhibit different partition abilities to the DOPC vesicles. For C12Glu, the molecules form shorter wormlike micelles with a lower surface charge at all the pHs and temperatures used, and the partition coefficient of C12Glu into the DOPC vesicles does not change with temperature and pH. Differently, the C12(Glu)2C12 molecules form fibers with a larger negative charge and belts with a smaller negative charge at pHs 7.4 and 5.6, respectively, no matter what temperature is used. As a result, the partitions of C12(Glu)2C12 into the DOPC vesicles are markedly different at these two pH values, and the belts at pH 7.4 exhibit a stronger partition ability than the fibrils at pH 5.6. Moreover, at any temperature and pH, C12(Glu)2C12 shows a stronger partition ability than C12Glu. This work can help to understand the relationship between the molecular structure and aggregate structure of amino acid amphiphiles and their partition abilities into the biomembranes.

Abstract
The effects of co-existing anions (NO3- or SO42-) on the removal of sodium dodecylsulfate (SDS), representing anionic organic pollutants, by Ca-based layered double hydroxide (CaAl-LDH-Cl) are investigated to provide fundamental insights on the ionic surfactant removal in the presence of co-existing anions, and facilitate the establishment of a practical and advanced water treatment for environmental remediation. The SO42- system shows higher adsorption capacity (4.43 mmol·g-1) and larger d-spacing of adsorption resultant (3.4 nm) than the control system with no co-existing anion (3.64 mmol·g-1, 3.25 nm) and the NO3- system (3.82 mmol·g-1, 3.27 nm). The macroscopic and microscopic analyses reveal that, NO3- had a little influence on the SDS removal due to strong electrolysis, while SO42- could significantly promote the SDS removal. Moreover, the reaction mechanism varies under different molar ratios of DS-/SO42-.

Abstract
Emulsions are known to be effective carriers of hydrophobic drugs, and particularly injectable emulsions have been successfully implemented for in vivo controlled drug release. Recently, high internal phase emulsions have also been used to produce porous polymeric templates for pharmaceutical applications. However, emulsions containing dissolved biopolymers both in the oil and water phases are very scarce. In this study, we demonstrate such an emulsion, in which the oil phase contains a hydrophobic biodegradable polymer, MaterBi®, and the water phase is aqueous sodium alginate dispersion. The two phases were emulsified simply by ultrasonic processing without any surfactants. The emulsions were stable for several days and were dried into composite solid films with varying MaterBi®/alginate fractions. The films were loaded with two model drugs, a hydrophilic eosin-based cutaneous antiseptic and the hydrophobic curcumin. Drug release capacity of the films was investigated in detail, and controlled release of each model drug was achieved either by tuning the polymer fraction in the films during emulsification or by crosslinking sodium alginate fraction of the films by calcium salt solution immersion. The emulsions can be formulated to carry either a single model drug or both drugs depending on the desired application. Films demonstrate excellent cell biocompatibility against human dermal fibroblast, adult cells.

Abstract
One of the primary causes of skin irritation is the use of body wash cosmetics and household chemicals, since they are in direct contact with the skin, and they are widely available and frequently used. The main ingredients of products of this type are surfactants, which may have diverse effects on the skin. The skin irritation potential of surfactants is determined by their chemical and physical properties resulting from their structure, and specific interactions with the skin. Surfactants are capable of interacting both with proteins and lipids in the stratum corneum. By penetrating through this layer, surfactants are also able to affect living cells in deeper regions of the skin. Further skin penetration may result in damage to cell membranes and structural components of keratinocytes, releasing proinflammatory mediators. By causing irreversible changes in cell structure, surfactants can often lead to their death. The paper presents a critical review of literature on the effects of surfactants on the skin. Aspects discussed in the paper include the skin irritation potential of surfactants, mechanisms underlying interactions between compounds of this type and the skin which have been proposed over the years, and verified methods of reducing the skin irritation potential of surfactant compounds. Basic research conducted in this field over many years translate into practical applications of surfactants in the cosmetic and household chemical industries. This aspect is also emphasized in the present study.

Abstract
In recent years, emulsions stabilized by micro- or nanoparticles (known as Pickering emulsions) have attracted much attention. Micro- or nanoparticles, as the main components of the emulsion, play a key role in the preparation and application of Pickering emulsions. The existence of particles at the interface between the oil and aqueous phases affects not only the preparation, but also the properties of Pickering emulsions, affording superior stability, low toxicity, and stimuli-responsiveness compared to classical emulsions stabilized by surfactants. These advantages of Pickering emulsions make them attractive, especially in biomedicine. In this review, the effects of the characteristics of micro- and nanoparticles on the preparation and properties of Pickering emulsions are introduced. In particular, the preparation methods of Pickering emulsions, especially uniform-sized emulsions, are listed. Uniform Pickering emulsions are convenient for both mechanistic research and applications. Furthermore, some biomedical applications of Pickering emulsions are discussed and the problems hindering their clinical application are identified.

Abstract
Protein analysis is a fundamental aspect of biochemical research. Gold nanoparticles are an emerging platform for various biological applications given their high surface area, biocompatibility, and unique optical properties. The colorimetric properties of gold nanoparticles make them ideal for point-of-care diagnostics. Different aspects of gold nanoparticle-protein interactions have been investigated to predict the effect of protein adsorption on colloidal stability, but the role of surfactants is often overlooked, despite their potential to alter both protein and nanoparticle properties. Herein we present a method by which gold nanoparticles can be prepared in various surfactants and used for array-based quantification and identification of proteins. The exchange of surfactant not only changed the zeta potential of those gold nanoparticles but also drastically altered their aggregation response to five different proteins (bovine serum albumin, human serum albumin, immunoglobulin G, lysozyme, and hemoglobin) in a concentration-dependent manner. Finally, we demonstrate that varying surfactant concentration can be used to control assay sensitivity.

Abstract
Gemini surfactants with hexadecyl tails and hydroxyethylated head groups bridged with tetramethylene (G4), hexamethylene (G6) and dodecamethylene (G12) spacers were shown to self-assemble at the lower critical micelle concentration compared to their conventional m-s-m analogs. The lipoplex formation and the plasmid DNA transfer into different kinds of host cells were studied. In the case of eukaryotic cells, high transfection efficacy has been demonstrated for DNA-gemini complexes, which increased as follows: G6<G4<G12. Different activity series, i.e., G6>G4>G12 has been obtained in the case of transformation of bacterial cells with plasmid DNA-gemini complexes, mediated by electroporation technique. Solely G6 shows transformation efficacy exceeding the control result (uncomplexed DNA), while the inhibitory effect occurs for G4 and G12. Analysis of physico-chemical features of single surfactants and lipoplexes shows that compaction and condensation effects change as follows: G6<G4 ≤ G12, i.e., agree with the order of transfection efficacy, which is supported by membrane tropic properties of G12. On the other hand, gel retardation assay and docking study testify low electrostatic affinity in G12/DNA pair, thereby indicating that hydrophobic effect probably plays important role in the lipoplex formation. Two factors are assumed to be responsible for the inhibition effect of gemini in the case of transformation of bacterial cells. They are (i) an unfavorable influence of cationic surfactants on the electroporation procedure due to depressing the electrophoretic effect; and (ii) antibacterial activity of cationic surfactants that may cause the disruption of integrity of cell membranes.
