Ion-resistant thickening agent as well as preparation method and application thereof

Abstract

The invention discloses an ion-resistant thickening agent. The ion-resistant thickening agent comprises the following components: sodium polyacryloyldimethyl taurate; an ammonium acryloyl dimethyl taurate / VP copolymer; the mass ratio of the two components is (25-300): (15-300). The invention also discloses a preparation method of the ion-resistant thickening agent. The preparation method comprises the following steps: S1, weighing the sodium polyacryloyl dimethyl taurate and the ammonium acryloyl dimethyl taurate / VP copolymer powder in proportion; and S2, weighing deionized water, slowly adding the sodium polyacryloyldimethyl taurate and the ammonium acryloyldimethyl taurate / VP copolymer powder into the deionized water while stirring, and stirring until the mixture is uniform and transparent to form the ion-resistant thickening agent. According to the ion-resistant thickening agent, the ion resistance of a thickening agent system is obviously improved, sufficient active ingredients can be conveniently added into a product, the thickening performance and the ion resistance are reserved at the same time, and the ion-resistant thickening agent can be used for preparing skin external application agents.

Description

technical field [0001] The invention belongs to the technical field of skin external preparations, and relates to an ion-resistant thickener and its preparation method and application. Background technique [0002] With the development of the national economy, the resources at the disposal of consumers have increased significantly, and the upgrading of social consumption has become an obvious trend. In the field of skin care products, consumers' skin care awareness and spending power are also rising, and the sales of cosmetics in my country still maintain a strong double-digit growth momentum. It is worth noting that with the rapid growth of the cosmetics industry, consumers' requirements and expectations for cosmetics have also increased, and cosmetics with good efficacy and experience have become an important basis for more and more consumers to choose cosmetics. More importantly, starting from January 2021, a number of cosmetics-related laws and regulations in my country...

Problems solved by technology

However, there are many defects in the above-mentioned raw materials, such as high addition amount, single skin feeling, single texture and appearance, etc.

Thickeners such as hydroxyethyl cellulose, xanthan gum, and agar also have good ion resistance; however, the thickening effect of these thickeners with strong ion resistance is very limited, and a large amount needs to be added to Meet the viscosity requirements of creams, lotions, etc.; in addition to increasing the cost, a large amount of addition will lead to a decrease in product experience, and the feeling will become sticky, which will affect the consumer's sense of use

Chinese patent document CN104069023A provides a new solution, which uses GT-700 and Sclerotin for compounding to increase the viscosity of the system formed by the two and improve the ion resistance of the system, but GT-700 has a skin feel Sticky, expensive and other obvious defects, there are certain application shortcomings in the actual formula
