Abstract

The invention discloses a polyamino acid gel and a preparation method and an application thereof. The polyamino acid gel is prepared from the following raw materials in percentage by mass: 1% to 8% of gamma-polyglutamic acid, 1% to 4% of epsilon-polylysine, 3% to 18% of alpha-cyclodextrin, 70% to 95% of water and the balance of functional ingredients. The polyamino acid gel has the advantages that the polyamino acid gel can be applied into masks or emulsions, nourishing creams, essences, eye creams, hand creams, cream shampoos, hair conditioners and sun creams, and can be used as an additive; the polyamino acid gel can be used as a washing-free mask, and can also be irradiated to obtain a polyamino acid gel mask with a double-network structure; by utilizing macromolecule self-assembly and chemical crosslinking, the cream type polyamino acid gel is obtained, the mechanical strength of a polymer gel is improved, and the introduction of harmful chemical matters caused by using a hair initiator in the polymerizing process is avoided.

Description

technical field

[0001] The invention relates to the field of biopolymer daily chemical products, in particular to a polyamino acid gel and its preparation method and application. Background technique

[0002] The facial masks currently on the market can be classified into the following types: washing facial masks, hard masks, soft masks, cream masks, and sticking masks, etc., which are cumbersome to use, have certain risks, and cause damage to the skin. Existing popular non-woven fabrics and silk masks have shortcomings such as dripping essence, poor moisturizing effect, and poor air permeability. γ-polyglutamic acid and ε-polylysine are currently the only two naturally occurring homopolymers of amino acids, both of which are produced by microbial fermentation and can be degraded into amino acid monomers in vivo. Absorbed by the body, no toxic side effects. γ-polyglutamic acid, ε-polylysine and α-cyclodextrin have obvious advantages compared with traditional gel materials,...
