含高内相凝胶乳液的护肤乳液开发与性能研究

Development and Performance Research of Skin Care Emulsions Containing High Internal Phase Gel Emulsions

将以水溶性乳木果油为乳化剂,包裹生育酚醋酸酯的葡萄籽油为油相制备的高内相凝胶乳液作为化妆品油相兼具功效组分加入护肤乳液体系中,测试了护肤乳液的理化指标,研究了其保湿性和抗氧化能力。结果表明,含高内相凝胶乳液的护肤乳液为水包油乳液,黏度较低,pH值适中,能够抵抗储存、加热、冷冻、离心等外界条件而保持良好的稳定性,室温下短期(2周内)存放时菌落总数符合国家标准,使用时有较好的保湿能力和抗氧化能力。

High internal phase gel emulsion,prepared from water-soluble shea butter as an emulsifier and grape seed oil encapsulated withα-tocopherol acetate as the oil phase,was added to the skin care emulsion system as a cosmetic oil phase with both efficacy components.The physicochemical indices of the skin care emulsion were tested,and their moisture retention and antioxidant abilities were investigated.The results showed that skin care emulsions containing high internal phase gel emulsion were oil-in-water emulsions with good fluidity and a moderate pH value.They were able to maintain good stability against external conditions such as storage,heating,freezing,and centrifugation.The total number of colonies complied with national standards when stored at room temperature for a short period(within two weeks).When used,they exhibited better moisturizing and antioxidant capacities.
