Abstract

The invention discloses a stable cleaning product containing a glycine type surfactant, which comprises the following components based on the total weight of the cleaning product: 15-30 wt% of a glycine type surfactant, the active content of which is 30%; 15-30 wt% of a zwitterionic surfactant, wherein the active content is 30%; 1-15 wt% of a thickening composition comprising fumed silica, an acrylic acid (ester)-based copolymer, polyethylene glycol-14M, or a combination thereof; and a carrier acceptable in the field of personal care, wherein the glycine type surfactant is selected from sodium cocoyl glycinate, high-salt sodium cocoyl glycinate, high-salt potassium cocoyl glycinate, potassium cocoyl glycinate, sodium lauroyl glycinate or a combination thereof, and the pH value of the cleaning product is 7-9.

Description

technical field [0001] The present invention relates to the use of a thickening composition in cleansing products containing glycine-type surfactants, and to stable cleansing products containing glycine-type surfactants. Background technique [0002] Amino acid anionic surfactants are used to partially or completely replace AES sulfate anionic surfactants, such as glutamic acid, sarcosine, and glycine, due to their low irritation, low toxicity, antibacterial properties, and biodegradability. Wait. Viscosity is a basic physical indicator for evaluating shampoos. It is not only one of the indicators that affect the stability of the cleaning system, but also affects consumers' preference to a large extent. For cleansers with sulfate-based surfactants, the viscosity of the system is relatively easy to thicken, but for cleansers with amino acid salt-based anionic surfactants, thickening is often a problem for formulators. The primary technical difficulty is faced when developin...
