Sodium Polyglutamate ●
TL;DR. This ingredient is primarily a humectant and skin-conditioning polymer, used to bind water and leave a smooth, hydrated feel. It can also add light film-forming and texture benefits in serums, creams, and masks.
What does Sodium Polyglutamate do in a cosmetic formula?
This ingredient is primarily a humectant and skin-conditioning polymer, used to bind water and leave a smooth, hydrated feel. It can also add light film-forming and texture benefits in serums, creams, and masks.
Is Sodium Polyglutamate clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. Sensitivity is uncommon, though very high-polymer formulas can feel tacky depending on concentration and base formula.
Is Sodium Polyglutamate sustainable?
This material is commonly made by fermentation from renewable carbohydrate feedstocks. It is water soluble and biodegradable, giving it a stronger environmental profile than many persistent synthetic film-formers.
Is Sodium Polyglutamate COSMOS-approved?
It is generally compatible with COSMOS-natural when made through accepted fermentation and neutralization routes, while organic certification depends on the feedstock and full manufacturing dossier. Its fit with Green Chemistry is strong because it can use renewable inputs, aqueous processing, and biodegradable polymer chemistry.
How does Sodium Polyglutamate work chemically?
The molecule is a high-molecular-weight, water-soluble anionic polypeptide with sodium counterions, which supports strong water binding and a flexible surface film. Typical use levels are about 0.05 to 1% in leave-on products, and performance can vary with molecular weight, electrolyte load, and formula pH.
