Sodium Polygamma-Glutamate ●
TL;DR. This ingredient is primarily a humectant and water-binding film former. It helps improve skin feel, reduce perceived dryness, and support a smooth finish in water-based formulas.
What does Sodium Polygamma-Glutamate do in a cosmetic formula?
This ingredient is primarily a humectant and water-binding film former. It helps improve skin feel, reduce perceived dryness, and support a smooth finish in water-based formulas.
Is Sodium Polygamma-Glutamate clean?
From a clean-beauty perspective, it is generally well tolerated and not a common allergen or restricted-list concern. The main quality check is documentation of fermentation origin, residual solvents or salts, and preservation of the supplied raw material.
Is Sodium Polygamma-Glutamate sustainable?
This material is commonly produced by microbial fermentation using plant-derived sugars or starches. It has favorable biodegradability expectations compared with persistent synthetic film formers, with sourcing impact tied mostly to feedstock agriculture and fermentation energy use.
Is Sodium Polygamma-Glutamate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when fermentation-derived and processed with permitted inputs. It fits Green Chemistry principles well because it can use renewable feedstocks, aqueous processing, and a biodegradable biopolymer structure.
How does Sodium Polygamma-Glutamate work chemically?
The molecule is a high-molecular-weight anionic biopolymer built from glutamate units linked through gamma-amide bonds, then neutralized as a sodium salt for water solubility. Typical use levels are about 0.05% to 1%, with performance influenced by molecular weight, pH, electrolytes, and compatibility with strongly cationic ingredients.
