Science

Mechanism of Action

Operating as a mild amino acid-type anionic surfactant, Sodium Myristoyl Glutamate reduces surface tension to facilitate the mixing of oil and water, enabling thorough cleansing, effective emulsification, and solubilization. It actively supports the skin's natural moisture barrier, ensuring a soft, hydrated feel post-application, and can mitigate the potential irritation from other surfactants. Its weakly acidic pH aligns with the skin's natural environment, and it enhances the penetration and effectiveness of other ingredients.

Research

Clinical Evidence

High confidence
Effective range 1–30%
Optimal

Effective as a co-surfactant in concentrations ranging from 1.0% to 15.0%, and as a primary cleanser typically between 1.0% and 30.0%, tailored to product type.

Key findings

  1. 01 Demonstrated efficacy as a primary surfactant in shampoos (1.0-5.0%) and in cleansing creams/shower gels (5.0-30.0%).
  2. 02 Proven effectiveness as a co-surfactant at concentrations of 1.0-15.0%.

Max tested
30%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel confirms Sodium Myristoyl Glutamate is safe for use in cosmetics when formulated to be non-irritating, with a maximum concentration of 30.0% reported in certain product types. While highly concentrated raw material forms (e.g., 83.3%) may cause serious eye irritation, this is not representative of its use in diluted cosmetic products.
