Problems solved by technology

[0007] The above technical solutions either require additional thickener assistance, or have limited thickening ability without adding additional thickeners
[0008] Moreover, a big problem with amino acid surfactants is that they tend to become jelly-like at low temperatures.

Abstract

The invention belongs to the field of daily chemistry and particularly relates to an amino acid self-thickening composition. The amino acid self-thickening composition is composed of sodium lauroyl sarcosinate, alkyl glycoside and a compound surfactant. The compound surfactant is one of cocamidopropyl betaine, sodium cocoyl alaninate and disodium cocoamphodiacetate. The weight ratio of sodium lauroyl sarcosinate to compound surfactant is 1: 1 to 1: 4. The ratio of the weight sum of sodium lauroyl sarcosinate and compound surfactant to the weight of alkyl glycoside is 12-16: 1-3. The amino acidself-thickening composition has a strong self-thickening capability and does not form jelly at a low temperature. The invention also discloses a composition system and a use of the system.

Description

technical field [0001] The invention relates to the field of daily chemicals, in particular to an amino acid self-thickening composition, system and application. Background technique [0002] 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 functions, but also have mild surface activity. [0003] CN201310127769.5 discloses an amino acid-type surfactant self-thickening composition, which contains cocamidopropyl sulfobetaine and sodium lauroyl sarcosinate as thickeners. [0004] CN201310153564.4 discloses an agricultural thickening synergist, which contains fatty alcohol polyoxyethylene ether sulfate, alkyl glycoside, sodium lauroyl sarcosinate, and sodium dodecylbenzenesulfonate. It is recorded in the description: Containing fatty alcohol polyoxyethylene ether sulfate, the additive itself has the characteristics of better wetting and synerg...
