Sodium Hyaluronate \ Hyaluronic Acid\ ●
TL;DR. This ingredient is primarily a humectant and skin-conditioning film former. It binds water at the skin surface, improving hydration feel, slip, and the appearance of plumpness.
What does Sodium Hyaluronate \ Hyaluronic Acid\ do in a cosmetic formula?
This ingredient is primarily a humectant and skin-conditioning film former. It binds water at the skin surface, improving hydration feel, slip, and the appearance of plumpness.
Is Sodium Hyaluronate \ Hyaluronic Acid\ clean?
This ingredient is well-tolerated and generally unproblematic in clean-beauty frameworks, with no common restricted-list flags. Very low-molecular-weight grades can feel more active on compromised skin, but it is not a fragrance allergen or a typical sensitizer.
Is Sodium Hyaluronate \ Hyaluronic Acid\ sustainable?
This material is now commonly made by bacterial fermentation rather than animal extraction. It is a biodegradable polysaccharide, with sustainability considerations mainly tied to fermentation inputs, water use, and purification energy.
Is Sodium Hyaluronate \ Hyaluronic Acid\ COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when produced through compliant fermentation and preserved according to the standard. It aligns well with Green Chemistry through biobased production, aqueous processing, and biodegradability.
How does Sodium Hyaluronate \ Hyaluronic Acid\ work chemically?
The molecule is a linear anionic polysaccharide built from repeating glucuronic acid and N-acetylglucosamine units, with molecular weight grades ranging from very small fragments to over 1 million Da. Typical use levels are about 0.01% to 1%, and it is most stable around mildly acidic to neutral pH, while high heat, enzymes, strong acids, strong bases, and some cationic systems can reduce performance.
