Abstract: A sunblock or sunscreen composition with enhanced photostability and a method for preparing and using the novel photostabilizer are provided. The combination of avobenzene, dimethyl capramide, and polyester-8, a copolymer of adipic acid and neopentyl glycol that is terminated with cyanodiphenyl propenoic acid, provides an extra layer of protection to keep the sunscreen working longer to protect the skin from damaging ultraviolet rays, namely, UVA and UVB. Sunblock products with SPF-15 for moderate sun protection. SPF-30 for higher sun protection and SPF-50, specially formulated for fair skin provides high sun protection. The sunblock compositions with the novel photostabilizer have a clean, dry formula that glides on easily for quick absorption, while enlisting sea plant extracts and anti-oxidant vitamins A, C, and E that aid in the reduction of cell damaging free radicals for younger looking skin.
