N-Stearoyl-L-glutamic acid

N-Stearoyl-L-glutamic acid (CAS 3397-16-8) is an amino acid-based surfactant derived from stearic acid and glutamic acid. It is commercially available under trade names including Amisoft HS-11PF and Stearoyl Glutamate. No E-code designation applies to this ingredient.

In personal care formulations, it functions as an emulsifier by bridging oil and water phases through its dual hydrophilic-lipophilic structure, contributing to stable creams and skin-feel modification. In cleansing applications, its mild surfactant character allows effective soil removal at near-physiological pH, reducing irritation potential compared to conventional anionic surfactants.

This ingredient is subject to REACH registration requirements for EU supply and is commonly handled under cosmetic-grade specifications aligned with ISO 16128 natural origin criteria. It is supplied in solid or powder form depending on grade. Buyers should confirm purity specifications and lot documentation with the supplier prior to procurement.
