Brassica campestris oleifera oil unsaponifiables is a plant extract used in cosmetic preparations. Brassica campestris oleifera oil unsaponifiables is obtained from residues of rapeseed oil which are left over as "unsaponifiables" during the saponification of the oil. The oil makes the hair easy to comb, smooth, soft and shiny and gives it volume. It also has a skin-protecting and antiseborrhoeic effect.
