Science
Mechanism of Action
Operating as an anionic surfactant, TIPA-Lauryl Sulfate functions by significantly reducing the surface tension of aqueous solutions. This action facilitates the emulsification and dispersion of lipophilic substances such as sebum, makeup, and environmental pollutants, allowing them to be thoroughly rinsed away from the skin and hair surface.

The Formula
Formulation
Stability
Generally stable in alkaline, weak acid, and hard water conditions, but readily hydrolyzes in strong acidic environments. The manufacturing process may generate 1,4-dioxane, which is considered acceptable at concentrations below 30 ppm. Formulations containing this ingredient must avoid nitrosating environments.
Conflicts
- Strong acids
- Nitrosating agents
Safety
Safety Profile
The ingredient's use is regulated under Annex III of the EC Cosmetics Regulation following SCCS assessment, which specifies purity criteria, maximum concentrations, and permissible product categories to ensure safety. A critical consideration is the potential for nitrosamine formation from impurities, with strict limits enforced by European regulations. Additionally, its manufacturing process can generate 1,4-dioxane, a probable carcinogen, though concentrations below 30 ppm are generally deemed acceptable.
