Formulation of Liquid Soap Contains Cow's Milk from Middle Small Enterprise in Cimahi

Abstract

Skin is one of the outermost body defenses which is often exposed to foreign objects. Cleaning the dirt on the skin is done using soap. Cow's milk contains protein and fat which is effective to moisturize and nourish the skin. This study aims to make liquid soap preparations from cow's milk that serves to increase moisture on the skin. The study began with the collection of cow's milks from small and medium businesses in the city of Cimahi and organoleptic characteristics testing. Then a series of liquid soap formulas were made containing 0, 5, 10 and 20% cow's milk. Liquid soap preparations obtained were evaluated including physical evaluation (organoleptic, pH, viscosity, and stability tests) and testing of respondents (testing the emollient power with a skin analyzer, preference test, and cleaning effectiveness). The data obtained were analyzed statistically using paired t-test. Physical evaluation results showed that the search for soap formula containing cow's milk was stable for 28 days storage. The test results of the respondents showed that the most preferred preparation is liquid soap containing 15% cow's milk with reasons for being comfortable, soft and not sticky to the skin. The results of the cleaning effectiveness test also showed liquid soap containing 15% cow's milk can clean the dirt and make up.Keywords: Cow milk, liquid soap, emollient
