Problems solved by technology

[0003] However, for personal cleansing products, amino acid surfactants have the problem of difficult or even impossible thickening; at present, major manufacturers usually add polymer thickeners to solve the problem
And this will bring the following problems: 1) jelly-like appearance at low temperature; 2) discoloration is prone to occur at high temperature; 3) the foam of amino acid surfactants is suppressed; 4) in particular, the skin feel is affected by polymer materials during cleaning , the specific manifestations are sticky, dirty cleaning, and strong residual feeling; 5) Due to the high price of polymer raw materials, the cost space of the formula is squeezed out
[0004] CN201810800313.3 discloses an amino acid self-thickening system, which contains sodium lauroyl sarcosinate, alkyl glycoside and cocamidopropylamine oxide; the patent indicates that the system has excellent thickening performance; However, the stability of the system is not high, and it is prone to jelly phenomenon at low temperature, which affects the use effect at low temperature

Abstract

The invention belongs to the field of cosmetics, which relates to a thickening composition of sodium cocoyl alaninate salt and an application of the thickening composition. The composition is preparedfrom the following components: cocamidopropyl betaine or lauramidopropyl betaine, cocamidopropyl hydroxyl sulfonylbetaine or lauramidopropyl hydroxy sulfobetaine, cocamidomethyl MEA, cocamidomethyl MEA, inorganic salt and sodium cocoyl alaninate salt. The composition containing the sodium cocoyl alaninate salt has the excellent thickening effect, and when the composition is used in shampoo, a system can have the characteristics of large foam amount, high transparency, high stability, easiness in washing, low residue and low greasy feeling at the same time.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to a thickening composition of cocoyl alanine salt and an application thereof. Background technique [0002] Amino acid surfactants are gradually being used in daily chemical products due to their many advantages such as being mild and skin-friendly, rich in foam, and easy to degrade. Among them, personal cleansing products, such as shampoo, etc., are usually thickened to varying degrees in order to facilitate daily use and ensure product texture. However, the amino acid surfactant as the main surface active agent can easily cause the viscosity to fail to reach the viscosity of normal use, or even the viscosity of water, which is difficult to use in specific scenarios such as shampoo and facial cleanser. Amino acid surfactants have a self-thickening function, so in many daily chemical formulas, more and more amino acid self-thickening agents are used, which not only have self-thickening funct...
