Abstract
Free radicals can cause oxidative damage that plays a role in the aging process and cause degenerative diseases that appear on the skin, so that antioxidants are needed to reduce the cumulative effects of oxidative damage in the form of clay mask. One of the natural materials that can be used as a clay mask is pumpkin fruit. Beta carotene in the yellow pumpkin can be used as an antioxidant that has a mechanism of electron transfer process so that free radical can be deactivated, and the saponin content in yellow pumpkin that has cleanser effect on clay mask. The aims of this study was to determine the effect of the combination of bentonite and kaolin as clay minerals, as well as to get the optimum composition of the formula. Clay mask formula was optimized by using factorial design with design expert software ver 10.0. Responses used were the viscosity, spreadability, and drying time. The results showed that bentonite gived a significant effect to increase the viscosity, decrease spreadability and drying time. Kaolin gived a significant effect to increase the viscosity, decrease spreadability and drying time. Interaction of both had significant effect to increase the viscosity, spreadability, and drying time. The optimum formula clay mask that was obtained with design expert program was the one which the combination of concentration bentonite 23,95% and kaolin 18,60% with yield estimates viscosity 236222 cps; spreadability 4.20 cm; and drying time 14.65 minute. Keywords: bentonite, Cucurbita moschata, clay mask, kaolin
