RESEARCH ON PREPARATION OF HAND LOTION SUPPLEMENTED WITH GREEN TEA EXTRACT

Abstract

Green tea has been a familiar plant in Southeast Asia in particular as well as in Vietnam in general for thousands of years. This study aims to create a hand lotion containing C.sinensis extract and evaluate the quality of the cream preparation. Green Tea Extract is extracted by heating method and the polyphenol content is determined by UV-Vis photometry. Green Tea Extract Supplement Hand Cream is prepared and the composition evaluation includes uniformity, pH, thinness, and physical stability evaluation. The results of sensory tests of hand cream products show that the physical properties of uniformity, pH, thinness, and physical stability indicate that the preparation may be able to protect the surface of the hand skin.
