Composite protein peptide with skin care efficacy, hydrogel thereof and preparation method

Abstract

The invention relates to a composite protein peptide with skin care efficacy, a hydrogel thereof and a preparation method. The composite protein peptide comprises the following components by weight: 1.0-7.0 parts of silk fibroin peptide, 1.0-7.0 parts of casein peptide, and 0.1-2.0 parts of sericin. The composite protein peptide hydrogel comprises the following components by mass percentage: 0.5-20% of the composite protein peptide, 1.5-2.5% of an additive, 0.3-0.6% of a preservative, and the balance water, wherein the additive is one or more of xanthan gum, Carbomer, sodium alginate, and glycerin. The composite protein peptide and the hydrogel thereof provided by the invention have water supplementing, moisturizing, whitening, oxidation resisting and other skin care efficacy.

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a complex protein peptide with skin care effects, its hydrogel and a preparation method. Background technique [0002] People in modern society are under a lot of pressure in all aspects, and the surrounding environment of life and work is getting worse and worse, resulting in people's skin condition is not very good, the most obvious is that the skin becomes very dry, lack of moisture, long-term In this state, the skin will become rough, long spots and so on. Moreover, with the growth of age, the collagen in human skin will gradually decrease in metabolism, and the ultraviolet rays will reach the dermis through the epidermis, which will further promote the decomposition of collagen. In the absence of collagen in the skin, the collagen fibers will be cross-linked and solidified, making the cells When the interglucose decreases, the skin loses its softness, elasticity and luster...

AI Technical Summary

Problems solved by technology

However, in this process, the invention cannot form a protective film on the skin surface, and catechin and vitamin C are easily oxidized in the air, resulting in greatly weakened anti-oxidation and moisturizing effects

Moreover, the protein source of existing protein hydrogel cosmetics is generally large molecular weight collagen, which cannot be absorbed by the skin when applied externally to the skin surface, and has only a certain moisturizing effect on the skin surface, but cannot improve skin structure.
