Also known as
SSG Amisoft HS-11 N-Stearoyl Glutamic Acid Sodium Salt Sodium N-Stearoyl-L-Glutamate
Compatibility
Works well with:
Glyceryl Stearate Cetearyl Alcohol Shea Butter Jojoba Oil Tocopheryl Acetate Hyaluronic Acid
Use caution with:
High concentrations of cationic surfactants
Sodium Stearoyl Glutamate is an amino acid-derived anionic emulsifier that works well alongside nonionic co-emulsifiers such as Glyceryl Stearate or Cetearyl Alcohol to build stable O/W and W/O emulsions. It may interact unfavorably with high concentrations of cationic surfactants or conditioning agents due to charge neutralization. It is generally compatible with a wide range of cosmetic actives and performs best at slightly acidic to neutral pH.
Formulation notes
Sodium Stearoyl Glutamate is a mild, amino acid-based (glutamic acid) anionic emulsifier and surfactant derived from stearic acid. It is valued for its excellent skin compatibility, biodegradability, and ability to produce elegant, silky emulsions suitable for sensitive skin formulations. It is approved for use in natural and organic cosmetics and is generally considered safe at typical use levels, though it should be introduced into formulas at temperatures above its melting point (~65–70°C).
