Sodium Hyaluronate ●
TL;DR. This ingredient is primarily a water-binding humectant and skin-conditioning polymer. It helps increase hydration and can add a light, cushiony film feel in leave-on formulas.
What does Sodium Hyaluronate do in a cosmetic formula?
This ingredient is primarily a water-binding humectant and skin-conditioning polymer. It helps increase hydration and can add a light, cushiony film feel in leave-on formulas.
Is Sodium Hyaluronate clean?
From a clean-beauty perspective, it is generally well tolerated, non-fragrant, and not a common sensitizer. It is widely accepted in restricted-ingredient frameworks, with the main quality focus on purity, molecular-weight grade, and fermentation controls.
Is Sodium Hyaluronate sustainable?
This material is commonly made by microbial fermentation, although older animal-derived supply chains exist. It is biodegradable and does not raise notable persistence or bioaccumulation concerns.
Is Sodium Hyaluronate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when produced from allowed biotechnology or compliant raw materials. Its fit with Green Chemistry is strong because fermentation routes can use renewable feedstocks, water-based processing, and biodegradable polymer chemistry.
How does Sodium Hyaluronate work chemically?
The molecule is a water-soluble, anionic linear polysaccharide made of repeating sugar-acid and amino-sugar units, supplied in molecular-weight grades from below 50 kDa to over 1 MDa. Typical use levels are about 0.01-0.5%, with best stability near pH 5-8; strong acids, strong bases, oxidizers, heat, and high electrolyte loads can reduce viscosity or depolymerize it.
