Galactoarabinan

Product Description

Galactoarabinan (GA) is a mild, water-soluble polysaccharide extracted from the Larch tree (Larix species). As a highly functional biopolymer, it offers a sustainable "green chemistry" solution for modern cosmetics. Its standout capability in the B2B market is its role as an SPF Booster. GA improves the dispersion of inorganic UV filters (like Titanium Dioxide and Zinc Oxide) and forms a uniform film on the skin, significantly enhancing the sun protection factor of formulations without the need for additional chemical filters. Beyond sun care, it promotes gentle skin renewal. Clinical data suggests GA accelerates cell turnover similar to AHAs (Alpha Hydroxy Acids) but without the associated irritation or pH restrictions, making it perfect for sensitive skin lines. It also effectively reduces Trans-Epidermal Water Loss (TEWL), keeping skin hydrated and barrier-intact.

Product Uses

Galactoarabinan is a versatile asset for formulators, particularly in the Sun Care sector. It is widely used in mineral sunscreens, daily defense lotions, and BB creams to boost SPF efficiency and reduce the "whitening" effect of physical filters. In Skin Care, it serves as a core ingredient for "gentle resurfacing" serums and anti-aging toners, providing exfoliation benefits for users who cannot tolerate acids. Its film-forming properties also make it valuable in color cosmetics, helping to improve the wear-time of foundations and mascaras while maintaining a non-tacky, breathable feel on the skin.

Formulation Suggestions

Galactoarabinan is exceptionally easy to work with due to its high water solubility and low viscosity impact. It can be added to the aqueous phase at any stage of the manufacturing process, including cold processing. It demonstrates remarkable stability across a wide pH range (2.0 to 12.0) and is heat stable, making it compatible with high-temperature emulsification. Unlike many other natural gums, it does not become stringy or sticky. For SPF boosting applications, it is recommended to disperse it in the water phase before adding UV filters to ensure optimal film formation. Recommended usage levels range from 2.0% to 5.0%. Our recommendations are for reference only; please follow the advice of your formulator for actual production.
