DEA-DODECYLBENZENESULFONATE.

Questionable CAS 26545-53-9 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

DEA-DODECYLBENZENESULFONATE is a potent anionic surfactant and cleansing agent primarily utilized in rinse-off formulations. It effectively emulsifies oils and dirt, facilitating their removal from the skin and hair, while also contributing to rich foam and formulation stability.

Summary

Surfactant Cleansing Agent Emulsifier Foaming Agent

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between liquids and solids, enabling water to mix with oil-based impurities. As an emulsifier, it helps disperse immiscible substances, allowing for effective cleansing and rinsing. Its surfactant properties also enhance foaming and contribute to a more stable and texturally appealing product.

Research

Clinical Evidence

Low confidence
Effective range 0.002–3%
Optimal

Not explicitly defined for efficacy. However, related dodecylbenzenesulfonate salts are typically reported in use concentrations from 0.002% to 3% in non-irritating cosmetic formulations.

Key findings

  1. 01 A related salt, Sodium dodecylbenzenesulfonate, demonstrated severe irritation to rabbit skin at a 15% concentration. The CIR Expert Panel emphasized that the irritant potential of dodecylbenzenesulfonate salts, including DEA-DODECYLBENZENESULFONATE, is concentration- and pH-dependent, akin to other detergents.

Dusting Analysis

Not commonly dusted

DEA-DODECYLBENZENESULFONATE serves as a primary functional ingredient for cleansing and emulsification; it is not typically added in sub-efficacious 'dusting' amounts for marketing purposes.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel deemed DEA-DODECYLBENZENESULFONATE and related salts safe for cosmetic use when formulated to be non-irritating. Its irritant properties are comparable to other detergents, varying significantly with concentration and pH. While no specific maximum concentration for DEA-DODECYLBENZENESULFONATE was reported to CIR, related salts have been used at concentrations up to 3%. Formulations containing this ingredient must be carefully balanced to minimize its irritancy potential.

Verdict

Questionable

While DEA-DODECYLBENZENESULFONATE offers strong cleansing and emulsifying capabilities, its high irritancy potential at elevated concentrations necessitates rigorous and precise formulation to ensure skin compatibility, making its selection for sensitive skin or general precision skincare products a careful consideration.
