Caffeine was successfully vehiculized in this optimized bioadhesive emulgel formulation, which showed high robustness regarding the process variability. There were no significant changes in the critical quality attributes after the incorporation of the active ingredient and a promising stability was observed for at least one year. Results suggested that the optimized emulgel is an interesting topical biodhesive delivery system for cosmetic applications, including agents for skin conditioning, not present in gels formulations.
