Question 1

What does Glycerin Sodium Hyaluronate do in a cosmetic formula?

Accepted Answer

This ingredient is a humectant system that binds water in the formula and on the skin surface. It supports hydration, cushion, and slip in serums, creams, masks, and cleansers.

Question 2

Is Glycerin Sodium Hyaluronate clean?

Accepted Answer

It has a strong clean-beauty standing because it is generally well tolerated, non-fragrant, and not a common allergen. The main formulation watchout is tackiness or pilling at higher use levels, not a restricted-list concern.

Question 3

Is Glycerin Sodium Hyaluronate sustainable?

Accepted Answer

It is commonly sourced from vegetable oil byproducts and microbial fermentation, though exact origin depends on the supplier. Both components are water soluble and expected to biodegrade, with a relatively favorable environmental profile when renewable feedstocks are used.

Question 4

Is Glycerin Sodium Hyaluronate COSMOS-approved?

Accepted Answer

It is generally permitted under COSMOS-natural and COSMOS-organic when the feedstocks and processing aids meet the standard. It aligns well with Green Chemistry principles through water compatibility, renewable or fermentation-based sourcing, and low persistence.

Question 5

How does Glycerin Sodium Hyaluronate work chemically?

Accepted Answer

It combines a small water-binding polyol with a high-molecular-weight anionic polysaccharide salt, giving both immediate humectancy and a hydrated film feel. The small component is often used around 2 to 10%, while the polymeric component is commonly used around 0.01 to 0.5% and performs best when well hydrated in the water phase at roughly pH 4 to 8.
