Sodium Hyaluronate Acid ●
TL;DR. This ingredient is primarily a humectant and skin-conditioning polymer that binds water and helps improve surface hydration. It can also add slip and a light film-forming feel in serums, creams, gels, and rinse-off products.
What does Sodium Hyaluronate Acid do in a cosmetic formula?
This ingredient is primarily a humectant and skin-conditioning polymer that binds water and helps improve surface hydration. It can also add slip and a light film-forming feel in serums, creams, gels, and rinse-off products.
Is Sodium Hyaluronate Acid clean?
It has a strong clean-beauty profile, with low sensitization potential and no major restricted-list friction when supplied at cosmetic purity. Some people may feel tightness from high levels in low-humidity settings, but that is a formulation issue rather than a core safety concern.
Is Sodium Hyaluronate Acid sustainable?
This material is commonly made by microbial fermentation, with older animal-derived sourcing now much less common in cosmetics. It is biodegradable and used at low concentrations, so its environmental footprint is usually driven more by fermentation inputs, purification, and packaging than by use level.
Is Sodium Hyaluronate Acid COSMOS-approved?
It is generally permitted under COSMOS natural and organic standards when made through approved biotechnology and compliant processing. From a Green Chemistry perspective, it aligns well because it can be fermentation-derived, water-compatible, effective at low levels, and biodegradable.
How does Sodium Hyaluronate Acid work chemically?
The molecule is a linear anionic polysaccharide built from repeating sugar-acid disaccharide units, with cosmetic grades ranging from very low molecular weight fractions to multi-million dalton polymers. Typical use levels are about 0.01% to 2%, most often 0.1% to 1%, and it is usually formulated in water at mildly acidic to neutral pH while being protected from strong oxidizers and prolonged high heat.
