Valuable CAS 41669-40-3 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

TEA-Myristate is a versatile salt formed from Triethanolamine and Myristic Acid, primarily utilized in skincare to enhance product stability and cleansing performance. It acts as a surfactant and emulsifier, facilitating the homogeneous blending of oil and water components in formulations.

Summary

Surfactant Emulsifying Cleansing pH Adjuster

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between immiscible phases, allowing oil and water to mix effectively. It also neutralizes acidic components, aiding in the formation of mild soaps that contribute to gentle yet thorough cleansing.

Stability

Derived from Triethanolamine, a weak base, TEA-Myristate is stable and functions optimally in alkaline environments, with a 1% solution of its base component having a pH of approximately 10. It is frequently employed to adjust and stabilize the pH of formulations, particularly when neutralizing acidic compounds.

Conflicts

  • N-nitrosating agents (e.g., certain preservatives containing 'nitro' or 'nitra') due to the potential formation of carcinogenic nitrosamines.

Safety

Sensitization risk Moderate

The CIR Expert Panel considers TEA-Myristate safe for use in cosmetics when formulated to be non-irritating. It must not be used in products where N-nitroso compounds can form, and levels of free diethanolamine should not exceed standard practices. For products intended for prolonged skin contact, the concentration of Triethanolamine and its derivatives, including TEA-Myristate, should not surpass 5%. This ingredient also holds approval for use as an indirect food additive.
