Science
Mechanism of Action
As an N-acyl derivative of sarcosine, TEA-Oleoyl Sarcosinate operates by reducing the surface tension of liquids, enabling the effective mixing of oil and water. This surfactant activity facilitates the removal of dirt and oils, acting as a cleansing agent. It also contributes to foam formation, functions as an emulsifier, and offers hair conditioning properties. Notably, this ingredient can also enhance the percutaneous absorption of co-formulated active substances.

Stability
Product stability and aesthetic qualities, such as viscosity and surface tension, are optimized within a pH range of 5.5 to 9.0, with minimum surface tension often observed between pH 5.5 and 7. Formulations below pH 5 may encounter instability due to the separation of the insoluble acid form.
Conflicts
- Ingredients capable of forming N-nitroso compounds, due to potential safety concerns.
- Other ingredients whose safety profile relies on minimal skin absorption, as TEA-Oleoyl Sarcosinate can enhance dermal penetration.
- Magnesium salts exceeding 0.3% concentration in high-viscosity gel formulations, which may compromise physical stability.
Safety
Safety Profile
This ingredient is deemed safe for use in leave-on products at concentrations up to 5% and in rinse-off products at concentrations up to 12.9% by the CIR Expert Panel. Formulations must ensure the final product is non-irritating. It should not be incorporated into products where N-nitroso compounds could be formed. Data is insufficient regarding its safety in products intended for inhalation.
