OCTYLDODECETH-20.

Avoid CAS 32128-65-7 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

OCTYLDODECETH-20 is a polyoxyethylenated fatty alcohol, functioning primarily as a surfactant and emulsifier in cosmetic formulations. It facilitates the stable blending of disparate phases like oil and water, and aids in the gentle removal of impurities from the skin.

Summary

Cleansing Emulsifying Surfactant

Science

Mechanism of Action

This ingredient reduces the surface tension of liquids, allowing for the stable integration of immiscible substances to form emulsions. As an emulsifier, it stabilizes oil-in-water or water-in-oil formulations, preventing phase separation. Its surfactant properties also enable effective cleansing by solubilizing and lifting oily residues and environmental debris from the skin's surface. The branched octyldodecanol structure contributes to its effective surfactancy, complemented by the 20 ethylene glycol units that enhance its stability.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a direct safety assessment for OCTYLDODECETH-20, indicating insufficient data for a comprehensive review. A significant concern is the potential for contamination with toxic impurities, notably 1,4-dioxane, which is considered a probable human carcinogen. Concentrations of 1,4-dioxane are generally deemed acceptable if maintained below 30 ppm. While EWG reports low concerns for cancer, allergies, immunotoxicity, and reproductive toxicity, the weight of evidence regarding skin, eye, or lung irritation is currently listed as unknown or unassessed. Products containing OCTYLDODECETH-20 can achieve EWG VERIFIED status, provided they adhere to specific use restrictions and warnings based on company-submitted data.

Verdict

Avoid

Due to insufficient comprehensive safety data from the CIR Expert Panel and high concerns regarding potential contamination with 1,4-dioxane, OCTYLDODECETH-20 is not recommended for precision skincare formulations where ingredient purity and established safety profiles are paramount.
