MYRISTAMIDE MEA.

Valuable CAS 142-58-5 / ANTISTATIC, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

Myristamide MEA is a versatile cosmetic ingredient that functions as a skin and hair conditioning agent, while also enhancing product texture. It effectively boosts and stabilizes foam, and precisely controls viscosity, making it valuable in various formulations.

Summary

antistatic foam boosting hair conditioning skin conditioning viscosity controlling

Science

Mechanism of Action

This ingredient works by increasing the thickness of the aqueous portion within cosmetic products, thereby contributing to desirable textures and emulsion stability. It also imparts conditioning benefits by interacting with hair and skin surfaces, and its structure enables it to generate and stabilize foam.

Key findings

  1. 01 Deemed safe for use in rinse-off cosmetic products. For leave-on applications, it is safe at concentrations that limit the release of free ethanolamines to 5%, with a maximum use concentration of 17% (when considered with related Isostearamide MEA and Stearamide MEA).

Transparency

Dusting Analysis

Not commonly dusted

Myristamide MEA is primarily utilized as a functional ingredient for its benefits in formulation, such as viscosity control and foam boosting, rather than as a hero active ingredient. Therefore, it is not typically 'dusted' at sub-effective concentrations.

Sensitization risk Low

Myristamide MEA is considered safe for use in rinse-off products. In leave-on products, its use is restricted to concentrations that ensure the release of free ethanolamines does not exceed 5%, with a strict maximum concentration of 17%. The CIR Expert Panel explicitly states it should not be formulated in products where N-nitroso compounds can potentially form, citing toxicity concerns related to ethanolamines and nitrosamines. It is generally considered safe when meticulously formulated to be non-irritating.
