Sodium Hyaluronic Acid ●
TL;DR. This ingredient is primarily a humectant, binding water in leave-on skin care, hair care, and rinse-off formulas to improve surface hydration and slip. It can also add a light film-forming feel that supports a smoother finish.
What does Sodium Hyaluronic Acid do in a cosmetic formula?
This ingredient is primarily a humectant, binding water in leave-on skin care, hair care, and rinse-off formulas to improve surface hydration and slip. It can also add a light film-forming feel that supports a smoother finish.
Is Sodium Hyaluronic Acid clean?
This ingredient is broadly accepted in clean-beauty frameworks because it is well tolerated, low in sensitization potential, and not a common restricted-list concern. Very small molecular-weight grades may feel more active on reactive skin, but the material itself is generally considered straightforward.
Is Sodium Hyaluronic Acid sustainable?
This ingredient is commonly made by fermentation using sugar-based feedstocks, rather than extraction from animal tissue. It is water soluble and biodegradable, with low concern for persistence in waterways.
Is Sodium Hyaluronic Acid COSMOS-approved?
It is permitted under COSMOS-natural and can fit COSMOS-organic formulas when the manufacturing route and inputs meet the standard’s biotechnology and processing requirements. From a Green Chemistry view, fermentation sourcing, water-based processing, and biodegradability give it strong alignment.
How does Sodium Hyaluronic Acid work chemically?
The molecule is a linear, anionic polysaccharide salt built from repeating sugar-acid and amino-sugar units, and different molecular weights change viscosity, film feel, and skin-surface behavior. Typical use levels are about 0.01% to 0.5%, it is usually most stable near mildly acidic to neutral pH, and strong oxidizers, high heat, or very low pH can reduce polymer length and performance.
