Abstract

The invention belongs to the technical field of cosmetics, and discloses a sulfur-containing amino acid modified plant fruit polysaccharide, a preparation method and application thereof. The sulfur-containing amino acid modified plant fruit polysaccharide is mainly obtained by mixing plant fruit polysaccharides and mixed amino acids through carbonyl ammonia reaction; the mixed polysaccharide is composed of the following polysaccharide components: 20-30 parts by weight of Lycium barbarum polysaccharide, 20-30 parts by weight of jujube polysaccharide, 20‑30 parts by weight of apricot polysaccharide, mixed amino acids are made up of the following amino acids: 1‑5 parts by weight of cysteine, 1‑5 parts by weight of cystine, 1‑5 parts by weight of methionine; the weight of Lycium barbarum polysaccharide and cysteine The ratio is (20‑30): (1‑5). The invention also discloses a preparation method of the sulfur-containing amino acid modified plant fruit polysaccharide. The sulfur-containing amino acid modified plant fruit polysaccharide of the present invention enhances the solubility, moisturizing ability, whitening ability and thermal stability of the polysaccharide. The sulfur-containing amino acid modified plant fruit polysaccharide of the present invention is used for preparing cosmetics.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sulfur-containing amino acid modified plant fruit polysaccharide and a preparation method and application thereof. Background technique [0002] As people's demand for health and beauty is getting higher and higher, moist white and smooth skin is being respected by more and more women, and because of doubts about the toxicity and irritation of chemical cosmetics, people are paying more and more attention to the use of natural cosmetics. Plants prepare safe, efficient, mild, non-toxic and non-irritating natural whitening and moisturizing cosmetics. [0003] Plant fruits are rich in polysaccharides, such as polysaccharides in wolfberry, red dates and apricots, which have moisturizing, anti-wrinkle, anti-acne, anti-oxidation, anti-allergic, anti-inflammatory and other effects. However, when used in cosmetics, they have solubility, thermal stability, The disadvantage...
