Objective: Astaxanthin is one of the natural carotenoids with strong antioxidant characteristics which is widely used in skin care. The aim of this study was developed to formulate and characterize the antioxidant serum containing astaxanthin nanoemulsion and the diffusion rate studies using diffusion Franz method.
Methods: Astaxanthin nanoemulsion (As-NE) was prepared by using the self-nanoemulsifying method, followed by incorporation into serum preparation with the using carbomer as a gelling agent. Evaluation of serum As-NE was performed by physical, chemical characterizations and diffusion assay. Stability study was carried out in both accelerated (temperature of 40±2 °C/75±5%RH) and non-accelerated (at ambient temperature) conditions.
Results: These results suggest that antioxidant serum As-NE had good physical and chemical characteristics that are suitable for topical administration.
Conclusion: For the study of diffusion and stability under different storage conditions, it was proven that antioxidant serum As-NE form was packed in a carbomer as a gelling agent that could enhance the stability and diffusion rate of the astaxanthin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
