Problems solved by technology

[0003] However, apart from the price factor, it is difficult for amino acid surfactants to thicken through simple methods in the actual application process, so as to obtain products with suitable viscosity, which greatly affects their wide use in the cosmetics industry
The use of common high molecular polymer thickeners will have the following problems: 1) easy to change color at high temperature, easy to jelly at low temperature, 2) decrease in light viscosity; 3) inhibit the foam abundance of amino acid surfactants; 4) clean the skin The feeling is affected by the polymer raw materials, the specific performance is sticky, not clean, and the residual feeling is strong; 5) In order to achieve the purpose of thickening, it is necessary to increase the dosage, but the effect is still insignificant

Abstract

The invention relates to an efficient amino acid thickener and a preparation method thereof. The amino acid thickener is prepared from cetearyl behenate, polyethylene glycol-150 and C8-C14 alkyl glucoside, and the mass ratio of the cetearyl behenate to the polyethylene glycol-150 to the C8-C14 alkyl glucoside is 1:1:2. The amino acid thickener provided by the invention is semi-transparent particles from white to extremely light yellow, and can effectively thicken various amino acid surfactants and compositions thereof. The amino acid thickener is light-resistant, does not discolor at high temperature, is not jellied at low temperature, and does not influence the foam abundance and washing feeling of the amino acid type surfactants. The amino acid thickener is fast dissolved, moisturized, is non-irritant, easy to degrade, good in smearing and spreading hand feeling, capable of assisting in improving the film moistening feeling, easy to wash and free of residual heavy feeling. The aminoacid thickener provided by the invention can be used in a transparent formula to develop a transparent product. The preparation method is simple, and the product is stable, easy to store and easy forindustrial production and commercial popularization.

Description

technical field [0001] The invention relates to a thickener, in particular to a high-efficiency amino acid thickener and a preparation method thereof, belonging to the technical field of daily chemical products. Background technique [0002] In recent years, with the change of consumption concept and the improvement of environmental awareness, people have higher and higher requirements for daily chemicals, especially products with surfactant as the main raw material, in terms of safety, mildness and environmental protection. Amino acid surfactants are based on biological substances and are new natural green surfactants with excellent cleaning, sterilizing, wetting, foaming, emulsifying, mild and non-irritating, hard water resistance, biocompatibility, degradable, Regeneration and other performance. It is used in more and more fields, especially in the cosmetic industry. [0003] However, apart from the price factor, it is difficult for amino acid surfactants to thicken thr...
