Moisturizing composition and deep moisturizing liquid foundation

Abstract

The invention discloses a moisturizing composition, which comprises sodium hyaluronate cross-linked polymer, sodium hyaluronate, acetylated sodium hyaluronate and hydrolyzed sodium hyaluronate. The moisturizing composition of the present invention is compounded with four kinds of sodium hyaluronate with different characteristics to construct a 4D three-dimensional sponge layer structure, efficiently store and lock water, and precisely locate the surface, stratum corneum, epidermis and dermis of the skin, Instantly exerts three-dimensional moisturizing effect, replenishes water on the outer layer, locks water on the inner layer, and cares for the skin in all directions. The invention also discloses a deep moisturizing liquid foundation containing the moisturizing composition. The liquid foundation of the invention has the effect of deep moisturizing, and is refreshing and non-greasy.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a moisturizing composition and a deep moisturizing liquid foundation. Background technique [0002] The liquid foundations that claim to be highly moisturizing in current commercially available products are generally W / O or W / Si systems. Since the external phase of these two systems is oil, the skin feels the skin feeling from oil first during the application process. If you want to achieve better moisture retention, you usually choose to increase the proportion of the oil phase or use oil with a thick skin feel. The closed method reduces water loss to achieve the effect of moisturizing, but it also leads to sticky skin feeling and affects the breathability of the skin. O / W foundations generally have the problem of weak makeup staying power, which is generally solved by increasing the amount of film-forming agent in commercially available products. However, the fi...

AI Technical Summary

Problems solved by technology

However, the film formed by general silicone resin or other polyester-based film-forming agents is insufficient in ductility and air permeability, and is prone to tightness

And in the O / W emulsion, too high amount of oil phase film-forming agent will easily affect the stability of the emulsion

Due to the high content of water and other nutrients in the O / W system, which is beneficial to the growth and reproduction of microorganisms, the amount of preservatives often needs to be higher than that of the W / O or W / Si system, and the foundation is a resident product. As time goes by, after the solvent volatilizes, it is equivalent to increasing the concentration of preservatives in a disguised form. Coupled with the serious air pollution and other reasons, many users have skin allergies and other symptoms

[0003] Most of the products on the market that use hyaluronic acid as a moisturizing claim usually only use a single hyaluronic acid component in the formula, and often encounter problems with either the moisturizing effect is not ideal, or the skin feels too sticky due to excessive addition

Moreover, the mechanism of action of the currently marketed liquid foundations that claim moisturizing effects is usually limited to "throttling" (that is, reducing the water loss on the skin surface), instead of actively "opening up the source" and going deep into the inner layers of the skin for hydration.
