Science
Mechanism of Action
As an anionic surfactant, DEA-C12-15 Alkyl Sulfate functions by significantly lowering the surface tension at the interface of immiscible liquids like oil and water. This action allows for the dispersion of oily components within an aqueous phase, effectively facilitating cleansing, foam generation, and the creation of stable emulsions.

Formulation
Stability
Alkyl sulfates are generally susceptible to hydrolysis, particularly at elevated pH values. While some proprietary formulations may maintain effectiveness across a broad pH spectrum, specific optimal pH stability for DEA-C12-15 Alkyl Sulfate is not explicitly documented. Hydrolytic stability can also vary based on the precise chemical structure.
Safety
Safety Profile
A direct safety assessment by the Cosmetic Ingredient Review (CIR) or SCCS specifically for DEA-C12-15 ALKYL SULFATE is currently unavailable. However, analogous alkyl sulfates have been deemed safe when formulated to be non-irritating, with irritancy being dependent on concentration and pH. A notable concern arises from the 'DEA' (Diethanolamine) component, which carries a potential risk of forming harmful nitrosamines if residual diethanolamine is present and can react with nitrosating agents within a formulation.

Verdict
While DEA-C12-15 Alkyl Sulfate functions as a versatile surfactant in cosmetic formulations, the absence of specific safety assessments and the inherent risk of nitrosamine formation associated with the 'DEA' component necessitate a highly cautious and critical evaluation of its inclusion.
