Problems solved by technology

[0004] However, the single macromolecular component in these products can only make the product have film-forming properties, but cannot achieve the effect of slow-release small molecule moisturizers
Small molecule moisturizers such as trehalose and sodium pyrrolidone carboxylate quickly penetrate the stratum corneum and are absorbed by the skin. They cannot exert their moisturizing effect in the stratum corneum for a long time, and the skin cannot be continuously supplemented by small molecule moisturizers, so it cannot achieve long-term maintenance. effective moisturizing effect

Abstract

The invention relates to moisturizing cream and a preparation method thereof. A composite humectant is added into the cream, so that the cream has a lasting and efficient moisturizing effect. The composite humectant comprises the following components in percentage by weight: 0.01-5.0 percent of sodium hyaluronate, 0.01-5.0 percent of chondrus crispus, 0.01-5.0 percent of sodium polyglutamate, 0.001-40.0 percent of glycerol, 0.01-2.0 percent of L-serine, 0.00-2.0 percent of L-proline, 0.0-0.3 percent of L-glutamic acid, 0.001-15.0 percent of betaine, 0.0-20.0 percent of urea, 0.001-15.0 percentof sodium pyrrolidone carboxylate, 0.0-10.0 percent of trehalose, 0.0-1.0 percent of a preservative, 0.001-0.5 percent of allantoin, and 0.001-5.0 percent of a pH regulator.

Description

Technical field[0001]The invention relates to the field of skin care products, in particular to a cream with moisturizing effect and a preparation method thereof.Background technique[0002]Cream is an important part of people's daily skin care products, and moisturizing has always been an important claimed effect in cream products. Most moisturizing creams achieve moisturizing effects by maintaining moisture in the stratum corneum, maintaining skin elasticity, and promoting skin barrier function repair. Whether the moisturizing effect of moisturizing cream is long-lasting and lasting has always been an important issue of people's attention.[0003]The moisturizing function of moisturizing creams currently on the market is mainly reflected in two aspects: First, the water phase of the cream provides water-soluble moisturizing ingredients, such as glycerin, urea, etc.; A moisturizing film is formed on the surface to reduce the loss of water dispersion in the skin's epidermis. At present,...
