Astragalus Gummifer Root Extract

What is Astragalus Gummifer Root Extract?

Astragalus Gummifer Root Extract comes from the roots of Astragalus gummifer, a shrub in the Fabaceae family native to arid regions of the Middle East, such as Iran. The extract yields tragacanth gum, a natural hydrocolloid composed mainly of polysaccharides like tragacanthin, which dissolves in water, and bassorin, which swells to form gels. This botanical material is processed into a viscous substance for cosmetic use, appearing in categories like moisturizers, sunscreens, and makeup. It works by interacting with water to thicken formulas, reinforce emulsion structures against separation, and deposit a sheer, flexible layer on the skin or hair for improved product performance and durability.
