Melanin

Melanin (CAS 8049-97-6) is a naturally derived biopolymer pigment with UV-absorbing and photoprotective properties.

Where is Melanin used?

• Sun care and photoprotection: broadband UV absorber in creams, lotions, and sprays targeting UVA and UVB exposure
• Cosmetics: natural-origin colorant and photoprotective agent in tinted moisturizers, foundations, and anti-aging products
• Hair care: color restoration and UV-protective treatments
• Pharmaceutical research and specialty drug delivery: carrier matrix evaluated for binding affinity and biological compatibility
• Commercially available melanins are typically derived from cuttlefish ink or fungal biomass.

Good to know: Natural-source material from cephalopod ink is the most established commercial form; biotechnology-derived grades are increasingly available. Food-grade and cosmetic-grade specifications are the most commonly available, with purity levels and sourcing documentation typically required by buyers.
