About

Linseed seed polysaccharide from flax is a well-documented cosmetic ingredient providing excellent hydration and skin-conditioning benefits, though it carries mild allergenicity from residual proteins.

Linum usitatissimum (flaxseed) seed polysaccharide is a mucilaginous polysaccharide fraction obtained from flax seeds. It is used in cosmetics for its hydrating and skin-conditioning properties. Flaxseed is not listed on any EU cosmetic restriction annexes. However, it contains trace proteins that may act as allergens in predisposed individuals, similar to other plant seed proteins. The ingredient is considered safe for cosmetic use with a reasonable safety record.
