Studies on building a natural sunscreen formula with titanium dioxide and zinc oxide
Abstract
The best way to prevent UV damage to the skin was to use sunscreen. There were many types of sunscreens, but they were formulated with chemical ingredients. Natural sunscreens were still less popular. So, the study was to develop a natural sunscreen formula from titanium dioxide and zinc oxide. By this experimental method, the natural sunscreen had been formulated with titanium dioxide, zinc oxide, shea butter and almond oil. The natural sunscreen with 2% TiO2, 6% ZnO, 20% shea butter, 4% almond oil and 9% beeswax were combined for a defined SPF value of 50,6. The product was milky white, soft, smooth, dense and uniform. The pH value was 6,08. S. aureus, P. aeruginosa and C. albicans, was not detected and aerobic microorganisms were below 102 cell/cfu. Heavy metals such as arsenic, lead, and mercury was not detected. The product did not damage the skin. The results also showed that this product followed the 7/VBHP-BYT circular on cosmetic management.
