TEA-DODECYLBENZENESULFONATE.

Valuable CAS 27323-41-7 / 68411-31-4 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

TEA-DODECYLBENZENESULFONATE is an anionic surfactant primarily employed in rinse-off cosmetic formulations. It efficiently cleanses, emulsifies, and generates foam, making it a versatile ingredient for removing dirt and oil from skin and hair.

Summary

Cleansing agent Foaming Surfactant Emulsifier

Science

Mechanism of Action

This ingredient functions as a robust surfactant, leveraging its amphiphilic structure to effectively lower surface tension. It enables water to mix with and suspend hydrophobic substances like dirt and oils, facilitating their removal from the skin and hair during rinsing. As an emulsifier, it stabilizes oil and water components within a formulation, contributing to a consistent product texture, and also provides a rich foaming effect.

Stability

TEA-DODECYLBENZENESULFONATE is highly soluble in water and readily integrates with both oil and water components in a formulation. Solutions containing this acidic salt typically exhibit a pH below 7.0. Its irritant potential and overall stability are critically dependent on the product's concentration and pH.

Safety Profile

CIR Status
Safe as used
Max tested
1%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that TEA-DODECYLBENZENESULFONATE is safe for use in cosmetics and personal care products when formulated to be non-irritating, with a maximum concentration of 1%. Concentrations exceeding this limit may lead to skin and scalp irritation. The Scientific Committee on Consumer Safety (SCCS) of the EU Commission also approves its use, subject to stringent restrictions under Annex III of EC Cosmetics Regulation (1223/2009). These include a prohibition against use in nitrosating systems, limits on secondary amine content (0.5% in raw materials), and nitrosamine content (50 µg/kg), requiring products to be stored in nitrite-free containers to prevent harmful nitrosamine formation.
