Abstract

A novel sunscreen containing Acacia catechu, remarkable local herb, was investigated for efficacy and standardized in this research.  The developed sunscreens were evaluated Sun Protection Factor (SPF), stability, skin allergy or irritation and the satisfaction. The highest SPF of A. catechu sunscreen with synthetic sunscreen agents was 30.344. While, the highest SPF of the A. catechu sunscreen without synthetic sunscreen agents was 24.381. The stability testing with the different conditions was found that the sunscreen products in the usual storage, had been stabilized even without preservative.  For irritation testing, there was no skin allergy and irritation from 20 volunteers.  Besides, results of the satisfaction evaluation for texture, consistency, sensory and odor after using the sunscreens, were high for all of the evaluation aspects.  Obviously, the results in this research revealed that A. catechu was applicable for being a great candidate in a sunscreen product.  Additionally, A. catechu sunscreen could prevent the adverse effects of UV radiation and artificial preservatives due to the UV absorption properties and antimicrobial properties of A. catechu.
