Snail grume extract as well as preparation method and application thereof in cosmetics

Abstract

The invention discloses snail grume extract which contains 0.1-5% of chondroitin sulfate, 0.1-5% of allantoin and 0.1-10% of collagen, wherein the molecular weight distribution of micro-molecule polypeptide is within 3000-5500 Dalton. The invention further discloses a preparation method and an application of the snail grume extract in cosmetics. The snail grume extract has the advantages that high pressure homogenate extraction and multi-stage membrane separation coupling techniques are adopted, the effective components of the snail grume are highly enriched, the snail grume extract contains 0.1-5% of chondroitin sulfate, 0.1-5% of allantoin and 0.1-10% of collagen, and particularly the molecular weight distribution of micro-molecule polypeptide is within 3000-5500 Dalton, so that the snail grume extract is very applicable to human body skin absorption, is beneficial for injured skin remediation and can promote heal and accelerate cell regeneration when being added into cosmetics.

Description

technical field [0001] The invention relates to a snail mucus extract and its application, in particular to a snail mucus extract, its preparation method and its application in cosmetics. Background technique [0002] Snails belong to gastropod terrestrial molluscs, which have high edible and medicinal value. The species commonly bred in China is the white jade snail, whose mucus mainly contains active ingredients such as collagen, allantoin, chondroitin sulfate, vitamins, and natural antimicrobial peptides. Among them, allantoin can regenerate the skin; protein and vitamins can increase the nutrition of the skin, making the skin more delicate and smooth. [0003] At present, most of the application and development of snail products are concentrated in the fields of food and cosmetics, and the research on it is mainly the extraction of polysaccharides, helicase, and secretions, but there is no research report on the extraction of cosmetic-grade snail mucus.
