Abstract

Lotion is a cosmetic product with a lighter consistency than cream, consisting of a mixture of oil phase and water phase, with emulsifying ingredients, moisturizers, active substances, and fragrances. Its function is to hydrate the skin, reduce irritation, and protect from environmental influences. Chamomile extract and niacinamide provide additional benefits, such as anti-inflammatory characteristics and increased skin moisture. This study aims to evaluate the effectiveness of triethanolamine (TEA) as an emulsifier in lotion stability during storage, as well as the effect of stirring temperature on lotion quality. The research method used a 2 x 3 factorial design quantitatively. Of the 8 lotion formulas tested, only formula 3 met the standard requirements of organoleptically, pH, specific gravity and homogeneity tests. This formula has a TEA volume of 2 ml, mixing time for 25 minutes at 70℃, pH 8, foam texture, slightly yellow-green color, specific gravity 0.972, and homogeneity. This formula provides a moisturizing effect on the skin without side effects

Abstract

The purpose of this study was to optimize the formulation of a natural liptint using red beet (Beta vulgaris L.) and waru leaves (Hibiscus tiliaceus L.) extracts with the addition of ZnO to enhance sun protection. The optimization process was conducted using Response Surface Methodology (RSM) involving three independent variables: extract ratio (1:2, 1:3, 1:4), homogenization speed (5.000, 10.000, 12.000 rpm), and homogenization time (4, 8, 10 minutes), generating 16 different formulations. Phytochemical characteristics such as betacyanin, anthocyanin, and SPF, as well as stability parameters including pH, viscosity, and density, were evaluated. The best formulation containing ZnO (F6) exhibited 0.0129% betacyanin, 0.0590% anthocyanin, and an SPF value of 18.1, while the best formulation without ZnO (F15) showed 0.0140% betacyanin, 0.0428% anthocyanin, and an SPF value of 12.7. The optimization value of this study estimates the production of liptint with ZnO (0.0104% betacyanin, 0.0593% anthocyanin, SPF 13.89) and without ZnO (0.0109% betacyanin, 0.0434% anthocyanin, SPF 11.05).
