Galactoarabinan ●
TL;DR. This ingredient is primarily a film-forming and skin-conditioning polysaccharide. It can improve slip, reduce tack, support moisture retention, and help stabilize or disperse particles in emulsions and sunscreens.
What does Galactoarabinan do in a cosmetic formula?
This ingredient is primarily a film-forming and skin-conditioning polysaccharide. It can improve slip, reduce tack, support moisture retention, and help stabilize or disperse particles in emulsions and sunscreens.
Is Galactoarabinan clean?
From a clean beauty perspective, this ingredient is generally well tolerated, non-fragrant, and has little restricted-list friction. The main quality check is supplier documentation for source, extraction method, and residual impurities.
Is Galactoarabinan sustainable?
This material is typically sourced from renewable tree-derived biomass and is expected to be biodegradable as a natural polysaccharide. Its sustainability profile depends on responsible forestry practices and low-residue extraction and purification.
Is Galactoarabinan COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when produced by permitted physical or aqueous extraction and purification methods. It aligns well with Green Chemistry principles because it can come from renewable feedstock, biodegrades readily, and does not require aggressive solvent chemistry in standard production.
How does Galactoarabinan work chemically?
The molecule is a branched, high-molecular-weight polysaccharide built mainly from galactose and arabinose sugar units, which lets it form a light, flexible film on skin or hair. Typical use levels are often around 0.5% to 5%, and it is water soluble with broad formulation compatibility across mildly acidic to neutral personal-care systems.
