In order to synthesized Aluminum Starch Octenylsuccinate (ASO), which is a natural polymer, aluminum salt and octenylsuccinic anhydride were used as additives to modify the starch. The synthesis process was undertaken in two steps. The synthesized ASO was subsequently incorporated into the formulation of a sunscreen crème where it served as an organic filter against UV radiations from the sun. Finally, a comparison was made between the results of the modified crème with those of the formulation without ASO. Corn starch ASO was synthesized using 2-octenylsuccinicanhydrideand aluminum sulfate; the synthesized product was then identified by FT-IR, H-NMR and 27AL-NMR. In the next stages, it was formulated into a sunscreen cream. Sensory analyses were performed on formulations with a SPF of 15 without ASO and those containing ASO at 2.0%. The tests were performed in silicoat a critical wavelength of 353 nm using BASF® Sunscreen Simulator The obtained results made it clear that the polymer could create a great feel of softness and velvetiness on skin when incorporated into a sunscreen formulation, while considerably attenuating the associated oiliness feel on the skin. 45 (75%) out of the 60 volunteers participated the study perceived the change in the brightness of skin following the application of the polymer formulation as either little or insignificant. Being natural and highly safe for human health, ASO is a good candidate for improving skin care products.
