Sodium Hyaluronate[2]

TL;DR. This ingredient is primarily a humectant and water-binding skin conditioner. It helps improve surface hydration, slip, and a temporary smoothing feel in leave-on formulas.

What does Sodium Hyaluronate[2] do in a cosmetic formula?

This ingredient is primarily a humectant and water-binding skin conditioner. It helps improve surface hydration, slip, and a temporary smoothing feel in leave-on formulas.

Is Sodium Hyaluronate[2] clean?

It is widely accepted in clean-beauty frameworks, with low irritation potential and no major restricted-list friction. Sensitivity is uncommon, though very low-molecular-weight grades can feel more active on some reactive skin types.

Is Sodium Hyaluronate[2] sustainable?

This ingredient is commonly made by microbial fermentation, though older or specialty grades may be animal-derived. It is water-soluble and biodegradable, with sustainability mainly tied to fermentation feedstocks, purification, and manufacturing energy use.

Is Sodium Hyaluronate[2] COSMOS-approved?

It is generally permitted under COSMOS-natural and COSMOS-organic when the source and processing route meet the standard’s requirements. It aligns well with Green Chemistry when fermentation-derived, since it can use renewable feedstocks and has a favorable biodegradability profile.

How does Sodium Hyaluronate[2] work chemically?

It is a high-molecular-weight, anionic polysaccharide salt built from repeating disaccharide units, with grades ranging from small fragments to multimillion-dalton polymers. Typical use levels are about 0.01% to 1%, and performance depends strongly on molecular weight, electrolyte load, pH, heat exposure, and shear during processing.
