Design and characterization of dual-pronged liposome-embedded gel for enhanced dermal delivery J. Surfactants Deterg. (IF 1.6) Pub Date : 2023-07-04 Sumedha Saxena, Poonam Kushwaha, Babita Shukla, Mohammad Ahmad
The present study aims to develop a combination of Nigella sativa seed oil (NSO) and virgin coconut oil (VCO)-loaded liposomal gel as a topical drug delivery system for vitiligo. A 3 × 3 factorial design approach was adopted to study the effect of variables on liposome characteristics and performance. A total of nine batches were formed. The cholesterol: phospholipid (wt/wt) and drug (NSO:VCO) ratios

O/D emulsions stabilized by quaternary ammonium gemini surfactants together with alumina nanoparticles J. Surfactants Deterg. (IF 1.6) Pub Date : 2023-06-29 Peng Wei, Faming Wu, Qinghua Zhang, Zhirong Liu
Oil-in-dispersion (O/D) emulsions are the focus in many fields due to their new microstructures and new functions. Herein, O/D emulsions were successfully prepared using series of cationic gemini surfactants 12-s-12 (s = 2, 3, and 6) and alumina nanoparticles. The microstructures and type of emulsions were identified using optical microscopy, zeta potential and contact angle methods. Gemini surfactants
