SODIUM STEAROYL GLUTAMATE
Sodium Stearoyl Glutamate is a mild surfactant of natural origin, derived from amino acids and fatty acids. Used in cosmetics as an emulsifier, it helps stabilize formulas while respecting skin balance. Well tolerated by sensitive skin, it contributes to a pleasant texture and good dispersion of active ingredients.

What is sodium stearoyl glutamate?
Sodium stearoyl glutamate is an ingredient of natural origin used mainly as mild emulsifier in cosmetic formulas. It comes from the reaction betweenglutamic acid, an amino acid naturally present in the skin, andstearic acid, a fatty acid derived from plant sources such as coconut or palm kernel oil. It is then neutralized with soda (sodium hydroxide) to obtain its sodium form.
Versatile and skin-friendly, sodium stearoyl glutamate helps to stabilize emulsions (water/oil mixtures) while improving texture products: creams, milks, lotions… It gives a silky, light touch, without a greasy effect.
Where does sodium stearoyl glutamate come from?
Its manufacturing is based on renewable resources :
- Theglutamic acid is generally obtained from fermentation of plant sugars,
- Thestearic acid comes from vegetable oils (such as coconut or palm kernel oil),
- Everything is transformed via processes ecological and non-polluting, which makes it an ingredient often present in clean, organic or natural formulas.
Properties and active ingredients
Sodium stearoyl glutamate performs several valuable functions:
- Mild emulsifier : allows water and oil to bind together stably, without irritating the skin.
- Texturing Agent : provides a velvety, non-sticky finish.
- Skin conditioner : improves the suppleness of the skin by strengthening the hydrolipidic film.
- Good tolerance : suitable for sensitive skin and baby products.
What are the benefits of sodium stearoyl glutamate?
- Creates a light, pleasant and easily absorbed texture.
- Protects and respects the skin barrier.
- Contributes to the good stability of care (avoids separation of phases).
- Promotes a gentle formulation, without irritation or greasy sensations.
- Brings an effect "second skin", perfect for daily care.
Its benefits
- Naturally emulsifies
- Improves the sensoriality of care
- Respects skin balance
How is it used in cosmetics?
Sodium stearoyl glutamate is present in:
- Moisturizing creams and milks : improves texture and stability.
- Organic or clean facial care : gentle alternative to aggressive synthetic emulsifiers.
- Products for babies or sensitive skin : excellent tolerance profile.
- Mild Cleansers : as a co-surfactant, it softens formulas.
Any side effects?
Sodium stearoyl glutamate is very well tolerated. It is non-comedogenic, non-irritating, with no known allergenic potential. He is also biodegradable and respectful of the environment.
