Stearoyl Glutamic Acid. [+/- May Contain/Peut Contenir: Iron Oxides (CI 77491 ●
TL;DR. This ingredient is primarily an amino-acid-derived anionic emulsifier and co-emulsifier, helping oil and water phases form stable creams, lotions, and makeup textures. It can also improve pigment wetting and spreadability in color cosmetics.
What does Stearoyl Glutamic Acid. [+/- May Contain/Peut Contenir: Iron Oxides (CI 77491 do in a cosmetic formula?
This ingredient is primarily an amino-acid-derived anionic emulsifier and co-emulsifier, helping oil and water phases form stable creams, lotions, and makeup textures. It can also improve pigment wetting and spreadability in color cosmetics.
Is Stearoyl Glutamic Acid. [+/- May Contain/Peut Contenir: Iron Oxides (CI 77491 clean?
From a clean beauty perspective, this ingredient is generally well tolerated and has little restricted-list friction. The main caveat is sourcing transparency for its fatty-acid portion, since that can come from palm, coconut, or other vegetable oils.
Is Stearoyl Glutamic Acid. [+/- May Contain/Peut Contenir: Iron Oxides (CI 77491 sustainable?
This material is typically made from fatty acids and an amino-acid-derived component, so it can be largely bio-based depending on supplier choices. It is expected to be biodegradable, with the main sustainability question being responsible sourcing of the fatty-acid feedstock.
Is Stearoyl Glutamic Acid. [+/- May Contain/Peut Contenir: Iron Oxides (CI 77491 COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when the feedstocks and manufacturing steps meet the standard’s requirements. Its Green Chemistry profile is favorable because it can use renewable inputs, functions at low levels, and does not rely on persistent silicone or fluorinated chemistry.
How does Stearoyl Glutamic Acid. [+/- May Contain/Peut Contenir: Iron Oxides (CI 77491 work chemically?
The molecule is an amphiphile, with a long C18 lipid tail and a polar amino-acid head group that can sit at the oil-water interface and reduce interfacial tension. It is commonly used at low levels, often around 0.1% to 1%, and performs best when the formulation pH supports partial neutralization for dispersion and emulsion stability.
