Embodiment 1

[0074] The preparation of embodiment 1 siloxane-hydrolyzed oat oligopeptide copolymer

[0075] (1) Preparation of Siloxane A: Weigh 1840g ClCH 2 SiCl 3 (Molecular weight 183.92) and 640g methanol (molecular weight 32.04) were mixed in a 3L glass reactor, 18.4g of petroleum ether was added as a catalyst, reacted at 90°C for 3h, and then washed with water to remove HCl and water generated during the reaction to obtain siloxane a. Among them, ClCH 2 SiCl 3 Mix with methanol in a molar ratio of 1:2.

[0076] (2) Weigh 154g of siloxane A prepared in step (1) and mix it with 154g of camellia oil, add 30g of oil-in-water emulsifier (oleth-10) and raise the temperature to 75°C, keep it warm to prepare an emulsion the oil phase;

Abstract

The invention discloses a siloxane-hydrolyzed oat oligopeptide copolymer as well as its preparation method and application. The structural formula of the copolymer is shown in Formula I. The present invention first reacts the hydrolyzed oat oligopeptide with the siloxane A shown in the formula II in the emulsion to obtain the siloxane-hydrolyzed oat oligopeptide shown in the formula III, and then polymerizes under catalytic conditions, thereby Copolymerization of siloxane‑hydrolyzed oat oligopeptides was achieved. In hair products, the copolymer can fill hair cuticles and repair damaged hair; in fabric products, it can effectively protect the fiber structure.

Description

technical field [0001] The invention relates to the fields of daily cosmetics and textiles, in particular to a siloxane-hydrolyzed oat oligopeptide copolymer and its preparation method and application. Background technique [0002] Polydimethylsiloxane (commonly known as silicone oil) has excellent film-forming and adsorption properties. As a hair conditioner, it is widely used in hair care products, such as shampoo, conditioner, baking cream, etc., which can give hair softness, softness, antistatic and other excellent properties. At the same time, as a fabric softener, it is widely used in textile products, which can give fabrics a soft and smooth feel. [0003] Proteins contain amino groups, carboxyl groups and other functional groups. The keratin and collagen produced by the hydrolysis reaction have a good penetration effect on hair and skin, and are often used as conditioners in skin and hair care products. [0004] Silicone modified protein is a copolymer of silicone ...
