Embodiment 1

[0020] This example investigates the compounding properties of sodium lauroyl sarcosinate (LS), cocamidopropylamine oxide (CAO), and alkyl glycosides (APG, C12-14 alkyl glycosides).

[0021] Accurately weigh a certain quality of sodium lauroyl sarcosinate, cocamidopropylamine oxide, alkyl glucoside, deionized water, citric acid, heat in a 45°C water bath, stir evenly, seal it and put it in a 25°C incubator for static Set it aside for 24 hours, measure the pH5.2-5.8 and viscosity after taking it out, and observe the appearance of the system.

[0022] The addition (percentage by weight) of sodium lauroyl sarcosinate, cocamidopropylamine oxide, alkyl glucoside is respectively: 4%: 4%: 0%; 4%: 4%: 1%; 4%: 4%:3%;6%:4%:0%;6%:4%:1%;6%:4%:3%;4%:6%:0%;4%:6%:1% ;4%:6%:3%;4%:8%:0%;4%:8%:1%;4%:8%:3%;6%:6%:0%;6%:6 %:1%;6%:6%:3%;8%:4%:0%;8%:4%:1%;8%:4%:3%;12%:4%:0%; 12%:4%:1%; 12%:4%:3%; 8%:8%:0%; 8%:8%:1%; 8%:8%:3%; 4%:12% :0%; 4%:12%:1%; 4%:12%:3%;

Abstract

The invention belongs to the field of daily chemicals and particularly relates to an amino acid self-thickening system. The system contains the following components by weight percent: 4%-8% of sodiumlauroyl sarcosine, 8%-12% of cocamidopropylamine oxide and 3% of alkyl glycoside, wherein the total use amount of sodium lauroyl sarcosine and cocamidopropylamine oxide is 16%; the pH value of the system is 5.2-5.8; and the solvent is water. The amino acid self-thickening system provided by the invention presents very excellent thickening performance when the total use amount of sodium lauroyl sarcosine and cocamidopropylamine oxide reaches 16% or above of the weight of the system and the use amount of alkyl glycoside reaches 30% or above of the weight of the system.

Description

technical field [0001] The invention relates to the field of daily chemicals, in particular to an amino acid self-thickening system. 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 synergistic performance, more stabl...
