Embodiment 1

[0039] Embodiment 1: Preparation of keratin

[0040] Wash the human hair (or wool) and pulverize it, and pretreat it with a sodium thioglycolate solution (sodium hydroxide to adjust the pH) with a pH value of 11 and a concentration of 0.5 mol / L at normal pressure and room temperature (20°C to 30°C) for 3 hours, then add urea to the solution, the amount of urea added is such that the concentration in the solution reaches 7mol / L, and then the reduction reaction is carried out at normal pressure and room temperature (20°C to 30°C) for 25 hours. After the reaction time expires, drop in Acetic acid adjusts the pH value of the reaction solution to 6-8, then feeds oxygen into the solution, and reacts at room temperature (20°C-30°C) for 0.5 hours. 80kD dialysis bag for dialysis, centrifugal separation to obtain the primary keratin solution with a molecular weight of 60,000 to 150,000 Daltons, salting out the primary keratin solution to obtain keratin solids, and vacuum (5-10mmHg colum...

Abstract

The invention discloses a keratin hairspray for hair, which consists of a keratin extracted from human hair or animal hair and having a molecular weight of 60,000-150,000 daltons and a vinyl pyrrolidone/vinyl acetate copolymer. The weight ratio of the keratin to the vinyl pyrrolidone/vinyl acetate copolymer is 0.2-3: 1. Modeling products for the hair, which are provided by the invention, comprisegel water, fixature and mousse, and the gel water, the fixature and the mousse all comprise the keratin hairspray for the hair.

Description

technical field [0001] The invention belongs to the field of hairdressing products, and in particular relates to hair-setting agents and products. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for beauty, more pursuit of natural beauty, and more natural hairdressing products. Many researchers have also carried out many studies, hoping to obtain hairdressing products closer to nature. Hou Huiyu (Guangzhou Chemical Industry; 2(38), 2010:) studied the properties of vinylpyrrolidone, the synthesis and properties of homopolymers, and the film-forming in hair care and styling products, and the lubrication, moisturizing and Application in film formation. Patent ZL200510007990.2 discloses a method and composition for styling keratin fibers, preferably human keratin fibers, especially hair, which comprises the following two main steps: applying to keratin fibers comprising at least one anionic styling polymer and...
