POTASSIUM COCOYL TAURATE.

Valuable CAS - / CLEANSING, SURFACTANT - CLEANSING

Potassium Cocoyl Taurate is a mild anionic surfactant derived from coconut oil and amino acids, primarily functioning as a cleansing agent and foam booster. It effectively removes impurities while maintaining skin hydration, making it suitable for a wide range of skin and hair care applications.

Summary

Surfactant Cleansing Foam Booster

Science

Mechanism of Action

This ingredient acts as a surfactant by lowering the surface tension of liquids, facilitating the emulsification of oil and water. This action allows for the effective removal of dirt, excess sebum, and other impurities from the skin and hair. Additionally, it significantly enhances foam production, generating a rich, delicate, and stable lather across diverse pH conditions without compromising the skin's natural moisture barrier.

Key findings

  1. 01 Reported use in bar soap formulations spans concentrations from 0.1% to 10% by weight of the final composition, with common examples within 1-3%.
  2. 02 Similar taurate surfactants, such as Sodium Cocoyl Taurate, have been utilized at concentrations up to 21.5% in rinse-off personal cleanliness products and up to 2% in leave-on skin care formulations.
  3. 03 Sodium Methyl Cocoyl Taurate, another related ingredient, has been observed at concentrations up to 13%, including in leave-on applications.

Stability

Taurate surfactants, including Potassium Cocoyl Taurate, exhibit robust cleansing and foaming capabilities over a broad pH spectrum and demonstrate stability against hydrolysis in both acidic and alkaline environments. Optimal stability for similar ingredients, such as Potassium Cocoyl Glycinate, is observed between pH 6-8, with Sodium Methyl Cocoyl Taurate also maintaining stable foam across a wide pH range.

Conflicts

  • This ingredient may enhance the dermal penetration of other formulation components. Caution is advised when co-formulating with ingredients whose safety profile is contingent on minimal skin absorption.
  • Studies involving Sodium Methyl Cocoyl Taurate, a similar ingredient, indicated an increase in the toxicity of N-ammonium thioglycolate in rabbit skin.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has deemed alkyl taurate amides and taurate salts, inclusive of Potassium Cocoyl Taurate, safe for cosmetic use within current practice and concentration ranges, provided they are formulated to be non-irritating. The panel specifically highlighted that these ingredients, particularly sodium methyl cocoyl taurate, could potentially augment skin penetration of other substances, necessitating careful consideration when formulating with penetration-sensitive ingredients.
