FORMULATION AND CHARACTERIZATION OF ALOE VERA COSMETIC HERBAL HYDROGEL

Abstract

Present study deals with the development and characterization of aloe vera cosmetic herbal hydrogel preparation using inner part of aloe vera leaf, acacia, hydroxy propyl methyl cellulose (HPMC), carbopol 934, glycerine, tartaric acid, potassium sorbate and sodium benzoate. Aloe vera liquid was prepared by heating at low temperature and the hydrogel was prepared by simple dissolving method of other ingredients in a specific manner. Four formulations were developed which differ in the ratio of hydrogel forming polymers. Formulation A1, A2, A3 and A4 were composed of acacia, HPMC, carbopol 934 in the ratio of 1:1:1, 1:2:1, 2:1:1 and 1:1:2 respectively. All the formulations were evaluated for percentage moisture content, transparency, smoothness, weight on drying, viscosity, pH and microbial growth. On the basis of evaluation parameter formulation A4 was selected as developed formulation. On the basis of evaluation study, it can be concluded that aloe vera cosmetic herbal hydrogel may be used for cosmetic purpose.
