Science
Mechanism of Action
This ingredient operates as a surfactant by reducing the surface tension of liquids, which facilitates the dispersion and emulsification of oils and dirt in water. This action results in robust foam generation and efficient cleansing, lifting unwanted substances from the skin surface.

Dusting Analysis
There is no available data to indicate that TEA-C12-14 ALKYL SULFATE is commonly 'dusted' or has specific dusting thresholds relevant to skincare formulations.
The Formula
Formulation
Stability
No specific optimal pH range for stability has been identified. However, irritation studies typically use solutions of TEA-C12-Alkyl Sulfate at neutral pH. The triethanolamine (TEA) component itself exhibits a pH of approximately 10 for a 1% solution.
Conflicts
- N-nitrogenating agents, due to the potential formation of carcinogenic N-nitroso compounds when combined with the Triethanolamine component.
Safety
Safety Profile
The CIR Expert Panel concluded that TEA and related TEA-containing ingredients are safe when formulated to be nonirritating and when levels of free diethanolamine are controlled. They specifically advise against use in products where N-nitroso compounds could form. Irritation has been noted at concentrations of 4.4% and 10% under specific test conditions. ECHA classifications indicate this substance can cause serious eye damage, skin irritation, and respiratory irritation, and is harmful if swallowed or inhaled, with long-lasting harmful effects on aquatic life.

Verdict
While TEA-C12-14 ALKYL SULFATE is an effective cleansing and foaming agent, its high irritancy potential at relevant concentrations renders its suitability questionable for precision skincare, particularly for individuals with sensitive or dry skin.
