Sodium Glycolate ●
TL;DR. This ingredient is mainly used as a pH adjuster, buffering salt, and mild humectant in water-based formulas. In acid-based exfoliating products, it can also represent the neutralized portion of the acid system and helps moderate formula pH.
What does Sodium Glycolate do in a cosmetic formula?
This ingredient is mainly used as a pH adjuster, buffering salt, and mild humectant in water-based formulas. In acid-based exfoliating products, it can also represent the neutralized portion of the acid system and helps moderate formula pH.
Is Sodium Glycolate clean?
From a clean-beauty perspective, it is generally acceptable, but it carries AHA-related context when used in exfoliating systems, where final pH and total acid level matter for stinging and sensitivity. It is not a major restricted-list ingredient on its own, though brands often review it alongside acid concentration, labeling, and use-site claims.
Is Sodium Glycolate sustainable?
This material is water-soluble, not expected to bioaccumulate, and the organic acid portion is generally biodegradable. Commercial supply can be petrochemical or plant-derived, so sustainability depends on feedstock transparency and manufacturing route.
Is Sodium Glycolate COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic only when the source and processing route meet the standard, such as accepted natural-origin feedstocks and permitted neutralization chemistry. From a Green Chemistry view, it scores better when plant-derived and made through lower-impact routes, with biodegradability as a clear advantage.
How does Sodium Glycolate work chemically?
The molecule is the sodium salt of a small alpha-hydroxy carboxylate, making it highly water-soluble and more buffered than the corresponding free acid. Its behavior depends strongly on formula pH, with lower pH shifting more material toward the free acid form and increasing exfoliation potential and stinging risk.
