About
A plant-derived protein complex that has been hydrolyzed and fortified with iodine, used in cosmetics for its film-forming and conditioning properties.
Extensins are hydroxyproline-rich glycoproteins found in plant cell walls. When hydrolyzed they become water-soluble peptides. The iodization adds elemental iodine, which in EU cosmetics is regulated under Annex III as a colouring agent and must not exceed specified concentration limits for rinse-off products.
Skin benefits
- Film-forming properties that condition skin
