Abstract

The invention relates to a microemulsion composition and a preparation method thereof. The microemulsion composition comprises the following components in percentage by weight: 10 to 20 percent of component A, 15 to 30 percent of component B and 50 to 70 percent of component C, wherein the component A comprises the following components in part by weight: 1.5 to 3 parts of non-ionic emulsifier, 0.5 to 1.5 parts of cetyl alcohol ether-6, 1.0 to 2.5 parts of stearyl ether-21, 5 to 10 parts of liquid paraffin and 2 to 8 parts of octyl palmitate or butyrospermum parkii; the non-ionic emulsifier islecithin, polyglyceryl fatty acid ester or a mixture thereof; the component B is deionized water; and the component C comprises glycerol and deionized water in a weight ratio of 1:3-7. The microemulsion composition provided by the invention has the liquid drops much smaller than those of an emulsion, is stable and favorable for skin penetration, promotes the exertion of effective substances, and can be widely applied to the cosmetics industry.

Description

technical field

[0001] The invention relates to a microemulsion composition and a preparation method thereof, and the microemulsion composition is suitable for the cosmetic industry. Background technique

[0002] The active ingredients of cosmetics determine its efficacy, but any cosmetic must be carried through a suitable carrier to exert its due effect. That is to say, the composition and properties of the cosmetic matrix directly affect the release, penetration and absorption of its active ingredients. Therefore, even with the same formula, the effects produced by different solvents are quite different.

[0003] Human skin mainly absorbs external substances through three ways: 1. Enter through hair follicles, sebaceous gland pores and sweat pores; 2. Enter directly through the keratinocyte membrane; 3. Enter through the gap between keratinocytes. Generally, the droplet of cosmetic emulsion is between 1-10 microns, and the active ingredients of the product cannot penetra...
