TEA-C12-13 PARETH-3 SULFATE.

Valuable / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

TEA-C12-13 Pareth-3 Sulfate is a versatile ingredient functioning primarily as a surfactant and emulsifier in cosmetic formulations. It enhances cleansing efficacy by reducing surface tension and ensures product stability by facilitating the homogeneous blending of oil and water phases.

Science

Mechanism of Action

As an anionic surfactant, TEA-C12-13 Pareth-3 Sulfate lowers the surface tension of liquids, enabling water to more effectively mix with and lift oily impurities and dirt from skin and hair for efficient rinsing. This action also supports robust foam generation. Concurrently, its emulsifying properties stabilize formulations by allowing normally immiscible oil and water components to remain uniformly dispersed, thereby maintaining product integrity and improving texture. It is recognized for its cleaning power and ability to contribute to skin moisturization.

Stability

This ingredient exhibits stability in alkaline, weakly acidic, and hard water conditions. However, it is unstable in strong acidic environments and prone to hydrolysis. It has the capacity to thicken formulations, contributing to good viscosity, but may be susceptible to yellowing over time.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that this ingredient, or similar compounds, is safe for use in cosmetics when formulated to be non-irritating. A primary concern for the 'TEA' component (triethanolamine) is the potential for N-nitrosamine formation if N-nitroso compounds are present; manufacturers are advised to take necessary precautions. The Scientific Committee on Consumer Safety (SCCS) has assessed TEA-C12-13 Pareth-3 Sulfate and its use is approved and/or restricted under Annex III of the EC Cosmetics Regulation, which sets maximum limits for nitrosamines. The U.S. FDA indicates that the trace levels of 1,4-dioxane (a manufacturing byproduct) typically found in cosmetics do not present a hazard to consumers.
