Purple fleshed sweet potato (Ipomoea batatas L.) is one of the natural ingredients that contain natural colour pigments are anthocyanin. Anthocyanin is a water soluble pigments which is naturally found in various type of plants. This study aims to make lipstick preparations using the purple fleshed sweet potato extract (Ipomoea batatas L.) as a natural dye. The method is used to get anthocyanin as a color of lipstick by using maceration extraction method. The weight of sample is 250 grams of dried fleshed purple sweet potato. The liquid for maceration used of 95% ethanol. The condition of maceration is acid by using 2% of citric acid. The filtrate of maceration process must be thickened. The basis of lipstick components consisted of cera alba, lanolin, cetyl alcohol, paraffin solid, oleum ricini, propylene glycol, and nipasol. The concentration of fleshed purple sweet potato extract is 0%, 2.4%, 4.5% and 14.6%. The result of research is that the lipstick is easy to apply, unstable color, homogenous, melting point above 500C, pH of 6 and all lipstick have an breaking point when load at 330 grams. Extract of purple fleshed sweet potato can’t be used as a pigment color in the manufacture of lipstick but additional material is needed that can keep the lipstick color from being degraded by pH, storage temperature, light, enzymes, oxygenation, sugar, structural differences in anthocyanins and concentrations of anthocyanins.

Gelatin is a type of protein that is extracted from collagen of skin, bone, or ligament (animal connective tissue) tissue. Cow bone, cowhide and pig skin are the materials commonly used to obtain gelatin. The purpose of this research was to determine the difference of NaOH concentration as soaking agent on gelatin making from skin of chicken leg (Gallus gallus domesticus) for 72 hours of soaking. Fresh skin of chicken leg weighing 250 g were immersed in NaOH solution with concentrations of 1%, 1.5%, and 3% for 72 hours, then extracted using n-hexane solution: alcohols in a ratio of 1: 3 and dried to obtain gelatin. The resulting gelatin is then analyzed for physicochemical characteristics such as sensory, yield, pH test, and water content test. The results of this study, mentioned that the concentration of 1% NaOH solution produces gelatin under average of yield of 6 g, neutral pH and water content of 11%. The concentration of 1.5% NaOH solution produces gelatin under average of yield 8 g, pH 7 and water content of 13%. The concentration of 3%NaOH solution produces gelatin under average of yield 4.144 g, pH 7 and water content of 7.11%. Based on the result, it can be concluded that a good solution of NaOH to get high yield under a concentration of 1.5% solution. The gelatin obtained under 1.5% solution in accordance with the standard gelatin. The characteristics of standard gelatin are colorless to yellow, odorless, tasteless, pH 7 (neutral), and moisture content below 16%.

Lipstick is one of the most used cosmetics by women. According to Tranggano and Latifah (2007), lipstick is a cosmetic applied to the lips, to protect the lips in cold and dry air so that the lips are not easy to dry and crack. Lipstick is used by women for a long time so that lipstick should be safe and do not cause irritation. Chemicals substances in the manufacture of lipstick can accidentally be consumed and long-term use so that its accumulation in the body would be harmful to health. Synthetic lipstick color is one part of the dangerous lipstick making material. Synthetic substances can be replaced with natural dyes. The use of natural dye limits on cosmetics is 5-15% (Mercado, 1991). One example of natural dyes that can be used is the dye from the Jati leaves (Tectona grandis L.f). This study aim is to prove that Jati leaves (Tectona grandis L.f) can be used as a natural dye in the material of lipstick. The method used in this research is the method of extraction maceration with jati leaf samples of 300 grams and ethanol of 96%. Component of lipstick formula which are cera alba, lanolin, vaseline, cetyl alcohol, paraffin solid, oleum ricini, oleum rosae, propylene glycol, butyl hydroxytoluene, methyl paraben, and the addition Jati leaf extract under the concentration of 0%, 18% , and 22%. The material of lipstick is easy to apply, stable, brown color, homogeneous, melting point of 600C, range pH between 3 at 4 and lipstick have a breaking point of 500 grams. Jati leaf extract (Tectona grandis L.f) can be used as a dye or color of lipstick.
