STEARAMIDOETHYL ETHANOLAMINE PHOSPHATE.

Valuable CAS 68134-13-4 / ANTISTATIC

STEARAMIDOETHYL ETHANOLAMINE PHOSPHATE is a functional ingredient primarily utilized in cosmetic formulations to stabilize mixtures of oil and water. It acts as an effective emulsifying agent, crucial for maintaining product integrity and texture. Additionally, this compound imparts antistatic properties and offers conditioning benefits for both skin and hair.

Science

Mechanism of Action

This ingredient functions primarily by acting as an emulsifying agent, which means it facilitates the stable dispersion of oil-based components within water-based solutions in cosmetic products. By reducing surface tension, it ensures that immiscible liquids combine effectively, thereby stabilizing emulsions. As an ethanolamide derivative, it also confers antistatic properties and acts as a conditioning agent, contributing to a smoother feel on the skin and improved manageability for hair.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that ethanolamides, including STEARAMIDOETHYL ETHANOLAMINE, are safe under current practices and concentrations, provided the final formulations are non-irritating. A crucial restriction for its use is to prevent the formation of N-nitroso compounds in cosmetic products. While no specific maximum concentration is provided for this exact ingredient, similar ethanolamides (like isostearamide, myristamide, and stearamide MEA) have been deemed safe in leave-on products up to 17%, with the caveat that the release of free ethanolamine is limited to 5%. There are documented reports of allergic contact dermatitis associated with stearamidoethyl diethylamine phosphate, a closely related compound. Ethanolamines, as a class, have demonstrated potential for skin irritation even at low concentrations (e.g., 1% MEA).

Verdict

Valuable

STEARAMIDOETHYL ETHANOLAMINE PHOSPHATE is a valuable functional ingredient for cosmetic formulations, serving as an emulsifier and conditioner, but requires precise formulation to meet safety restrictions concerning N-nitroso compound formation and potential irritation.
