Preservative-free moisturizing cream and preparation method thereof

Abstract

The invention provides preservative-free moisturizing cream and a preparation method thereof. The preservative-free moisturizing cream is prepared from raw materials in percentage by weight as follows: 0.05%-5.0% of polyglyceryl-3 methylglucose distearate, 0.01%-1.0% of cetostearyl alcohol, 0.05%-6.0% of white beeswax, 1.0%-10.0% of shea butter, 1.0%-5.0% of squalane, 1.0%-5.0% of dimethicone, 1.0%-5.0% of caprylic or capric triglyceride, 0.01%-0.3% of sodium hyaluronate, 0.01%-0.3% low-molecular-weight sodium hyaluronate, 0.01%-1.0% of a thickening agent, 1.0%-5.0% of 1,2-pentanediol, 1.0%-8.0% of glycerin, 0.01%-5.0% of a herba portulacae extracting solution, 0.01%-1.0% of capryl glycol, 0.01%-1.0% of decanediol and the balance of water. According to the preservative-free moisturizing cream, the problem of water shortage and dryness of skin surface is solved, a breathable membrane is formed, rapid permeability can be realized better, moisturizing and moisture sustaining capabilitiesare improved from skin bottom, skin damage can be prevented and repaired, luster and elasticity are restored, and appropriate moisture required by skin can be intelligently adjusted according to humidity change of the external environment. Under the preservative-free condition, moisturizing activity of hyaluronic acid with two molecular weights can be kept better, and moisturizing effect of the moisturizing cream is improved.

Description
