POTASSIUM COCOYL BARLEY AMINO ACIDS.

Insufficient Data / EMULSION STABILISING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

Potassium Cocoyl Barley Amino Acids is a gentle, amino acid-based surfactant derived from the fatty acids of coconut oil and amino acids extracted from barley protein. It is utilized for its mild cleansing properties, ability to emulsify, and its conditioning benefits for both skin and hair, fostering a creamy, stable foam.

Summary

Surfactant / Cleansing Skin-Conditioning Agent Emulsifying

Science

Mechanism of Action

This ingredient functions primarily as a mild surfactant, effectively reducing surface tension to facilitate cleansing and emulsification. It generates a stable, creamy foam while helping to preserve the skin's natural moisture barrier, thus mitigating the potential harshness often associated with more aggressive cleansing agents.

Stability

This water-soluble ingredient demonstrates optimal viscosity within a pH range of 5.8 to 6.3, consistent with observations for similar amino acid-derived surfactants. Related compounds, such as Potassium Cocoyl Hydrolyzed Collagen, are noted to form clear solutions at pH values exceeding 6.5.

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has categorized data for this specific potassium salt form as insufficient for comprehensive safety assessment. While broader categories like 'Amino Acid Alkyl Amides' and 'Hydrolyzed Barley Protein' have been evaluated (with Hydrolyzed Barley Protein generally concluded as safe), specific maximum concentration limits are unavailable for Potassium Cocoyl Barley Amino Acids. A related ingredient, Potassium Cocoyl Hydrolyzed Collagen, has shown non-irritating properties at concentrations up to 100% in human studies, though rare instances of sensitization were noted in patch tests.

Verdict

Insufficient Data

While functioning as a mild and beneficial surfactant for various skin types, comprehensive safety data specifically for Potassium Cocoyl Barley Amino Acids is currently insufficient, warranting careful consideration in formulation.
