Sodium Stearoyl Glutamate is an amino-acid-derived cosmetic ingredient made from stearic acid and L-glutamic acid and neutralized with sodium. It is primarily used as an emulsifying, cleansing, skin-conditioning and hair-conditioning ingredient in cosmetic and personal-care formulations.
The molecule combines a long-chain stearoyl group with the polar functionality of glutamic acid and a sodium counterion. This amphiphilic structure allows Sodium Stearoyl Glutamate to interact with both oil and water phases and provides useful surface-active properties.
Sodium Stearoyl Glutamate can be evaluated in creams, lotions, facial-care products, cleansing formulations, hair-care products, conditioners, makeup products and other personal-care systems depending on the formulation requirements and selected grade.
Sodium Stearoyl Glutamate is the monosodium salt of N-stearoyl-L-glutamic acid. The stearoyl portion is derived from stearic acid, a saturated C18 fatty acid, while the glutamate portion originates from L-glutamic acid.
It belongs to the amino-acid-based surfactant family and can provide emulsifying and conditioning functionality.
