Problems solved by technology

Chinese patent CN106691889A discloses a preparation method and application of a high skin retention ceramide nanocomposition. Although the patent examines the transdermal condition of ceramide after being carried, it does not further combine ceramide with other fat-soluble active substances Together, to construct a co-delivery system with better skin affinity, and play the beneficial role of ceramide in the transdermal delivery of other fat-soluble active substances
[0004] In addition, among the current carrier technologies related to ceramide, there is no technology that combines it with cholesterol and fatty acids to carry it

Abstract

The invention discloses a preparation method and product of a ceramide and fat-soluble active matter skin co-permeation carrier, and the ceramide and fat-soluble active matter skin co-permeation carrier comprises ceramide, fat-soluble active matter, phospholipid, cholesterol, fatty acid, phytosphingosine, liquid lipid, solid lipid, polyhydric alcohol and water. The carrier is positively charged; aternary permeation-promoting system can significantly improve the permeation amount of the ceramide in the cuticle of the skin, and the effects of the ceramide to enhance skin hydration and improve lipid fluidity of the cuticle are exerted, and thus, skin permeation of the fat-soluble active matter in the carrier is promoted, and the purpose of co-permeation is achieved.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a preparation method and a product of a skin co-penetration carrier of ceramide and fat-soluble active substances. Background technique [0002] Ceramides are a class of substances formed by the covalent combination of sphingosines with different degrees of saturation or different numbers of hydroxyl groups and fatty acids with different carbon chain lengths or degrees of saturation. Ceramide accounts for about 40% to 50% of the lipids in the stratum corneum of the skin. It is an important class of lipids to maintain the normal physiological functions of the skin. It can repair damaged skin and promote the renewal of the natural protective layer of the skin. As a natural moisturizing factor, ceramide has a strong ability to associate with water molecules. After it is applied to the skin, it can promote skin hydration and has excellent moisturizing effect. [0003] ...
