PEG-8 SOYAMINE.

Valuable CAS 61791-24-0 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-8 SOYAMINE is a polyethylene glycol derivative of soyamine, serving as a dual-function ingredient primarily recognized for its cleansing and emulsifying properties within skincare formulations. It aids in dispersing immiscible liquids and purifying the skin.

Summary

Cleansing Agent Emulsifier Surfactant

Science

Mechanism of Action

Functioning as a surfactant, PEG-8 SOYAMINE reduces the surface tension of liquids, thereby enhancing the efficacy of cleansing. Its emulsifying action is critical for establishing and maintaining stable, finely dispersed oil-in-water or water-in-oil mixtures, ensuring the integrity and consistency of cosmetic products.

Stability

PEG-8 SOYAMINE presents as a clear, colorless, viscous, and notably hygroscopic liquid. Its robust hygroscopic nature can prevent formulations from desiccating or crystallizing. Generally, the water solubility and hygroscopicity of polyethylene glycols decrease proportionally with an increase in their molar mass.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel determined that PEG-8 SOYAMINE and related PEG cocamine ingredients are safe for use in cosmetic formulations at current usage concentrations, provided the final product is non-irritating. However, earlier clinical observations have indicated PEG-8 SOYAMINE could function as a mild sensitizer and irritant, with reports of contact dermatitis associated with PEG-based topical applications.
