COMPARATIVE AND EXPERIMENTAL STUDY ON THE PROPERTIES AND POTENCY OF SYNTHESIZED ORGANIC AND MINERAL SUNSCREEN MOISTURIZER

This research work aims at synthesizing two different types of moisturizers: a body butter and a lotion. Based on the methodology, three samples of the body butter and lotion was produced, by varying the percentage of zinc oxide and Shea butter, the samples were analyzed with a UV- spectrophotometer to determine the transmittance and absorbance strength which was in turn used to determine the SPF. Vaseline which is a standard organic lotion was also analyzed to determine the transmittance, absorbance strength and SPF. The results were compared. Of all the moisturizers synthesized in this research, the lotion which had 10% zinc oxide had the highest absorbance strength, and hence the highest SPF. Therefore, it was concluded that a minimum of 10% zinc oxide should be used in the production of sunscreen moisturizers to provide moderate sun protectio
