COCOYL SARCOSINAMIDE DEA.

Questionable CAS 68938-05-6 / HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

Cocoyl Sarcosinamide DEA is a synthetic surfactant that reduces surface tension in cosmetic formulations, promoting even product distribution. It is primarily utilized for its ability to enhance foam, stabilize viscosity, and provide cleansing properties in various personal care products.

Summary

Hair Conditioning Cleansing Agent Surfactant - Foam Boosting Viscosity Controlling

Science

Mechanism of Action

This ingredient functions by lowering the surface tension of a liquid, enabling components to spread more uniformly within a formulation. As a foam booster, it improves the volume, texture, and overall stability of foam. Additionally, it contributes to product viscosity control and acts as a cleansing and hair conditioning agent.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Cocoyl Sarcosinamide DEA has not been formally reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. The Scientific Committee on Consumer Safety (SCCS) indicates that while it is not subject to specific restrictions as a fatty acid dialkanolamide, it can still lead to nitrosamine formation. Therefore, any secondary alkylamine or alkanolamine precursors must be absent from the finished product, except at technically unavoidable trace levels. The FDA advises consumers to be mindful of DEA-related ingredients, referencing a 1998 NTP animal study that linked topical DEA application to cancer through possible residual DEA; however, this study did not establish a human cancer risk.

Our Assessment

Verdict

Questionable

Given the potential for nitrosamine formation and unestablished human safety data regarding its association with DEA-related animal study concerns, its inclusion in precision skincare formulations is questionable, requiring stringent impurity management.
