About
A molluscan oxygen-transporting protein used in cosmetics as an antioxidant and anti-aging active, derived from invertebrates like horseshoe crabs.
Hemocyanin is a copper-containing oxygen transport protein found in arthropods and molluscs, distinct from the iron-based hemoglobin in vertebrates. In cosmetics, it is used as an active ingredient with antioxidant properties and is sometimes marketed as a substitute for growth factors in anti-aging formulations. Limited human clinical safety data exists specifically for cosmetic use of hemocyanin, though the protein's biocompatibility is supported by its natural occurrence and use in diagnostic reagents. It is not specifically restricted under EU Regulation 1223/2009, though vegan/vegetarian consumer concerns apply due to its animal-derived nature.
