Xanthan-carrageenan film containing sesame seed oil: A nanocomposite pharmaceutical platform for trichomoniasis treatment

Trichomoniasis is a common sexually transmitted infection that poses significant complications for women. Challenges in treatment include adverse effects and resistance to standard antimicrobial agents. Given this context, a sesame seed oil nanoemulsion (SONE) was developed and showed anti-Trichomonas vaginalis activity. To facilitate the local application of SONE, a polysaccharide film was developed using xanthan gum (XG) and κ-carrageenan gum (CG). A blend of XG and CG (at 2 %, ratio 1:3) plasticized with glycerol produced a more promising film (XCF) than using the gums individually. The film containing SONE (SONE-XCF) was successfully obtained by replacing the aqueous solvent with SONE via solvent evaporation technique. The hydrophilic SONE-XCF exhibited homogeneity and suitable mechanical properties for vaginal application. Furthermore, SONE-XCF demonstrated mucoadhesive properties and high absorption capacity for excessive vaginal fluids produced in vaginitis. It also had a disintegration time of over 8 h, indicating long retention at the intended site of action. Hemolysis and chorioallantoic membrane tests confirmed the safety of the film. Therefore, SONE-XCF is a biocompatible film with a natural composition and inherent activity against T. vaginalis, possessing exceptional characteristics that make it appropriate for vaginal application, offering an interesting alternative for trichomoniasis treatment.

Novel Arena of Nanocosmetics: Applications and their Remarkable Contribution in the Management of Dermal Disorders, Topical Delivery, Future Trends and Challenges

Nanocosmetics have attracted a considerable audience towards natural care due to their low cost, target-specific delivery, and reduced toxicity compared to chemical-based cosmetics. Nanofomulations, including nanoemulsions, nanotubes, and polymeric carriers, have become next-generation products explored for the multifaced applications of nanotechnology in skin care. The rise in the cosmetic industry demands innovative and personalized products designed using nanocarriers for better targeting and improving patient compliance. Furthermore, nanocosmetics increase the efficiency of skin permeation active ingredient entrapment, providing better UV protection. Moreover, it offers controlled drug release, targeting active sites and enhancing physical stability. Further, overcoming the drawback of penetration problems makes them sustainable formulations for precision medicine. Skincare nourishment with nanocosmetics using Indian spices helps to maintain, beautify, and rejuvenate human skin. Nanophytopharmaceuticals extracted from plants, including alkaloids, flavonoids, antioxidants, and volatile oils, are essential phyto-products for skin care. Nano herbals and nanocosmetics are a growing market and gift of nature that nourishes and cures skin ailments like acne, pemphigus, anti-aging, albinism, psoriasis, and fungal infections. The emerging concern is highlighted in the investigation of nanoformulation toxicity and safety concerns in skin care. Further, it helps to manifest research, development, and innovation in expanding the scope of herbal industries.
