Melanin

Melanin (CAS 8049-97-6) is a naturally derived biopolymer pigment used across cosmetic and pharmaceutical applications for its UV-absorbing and photoprotective properties.

Commercially available melanins are typically derived from natural sources such as cuttlefish ink or fungal biomass. Procurement demand is driven primarily by formulation use in sun care and skin care.

In sun care and photoprotection formulations, melanin functions as a broadband UV absorber, incorporated into creams, lotions, and sprays targeting both UVA and UVB exposure for maximum efficacy.

Cosmetic formulators use it as a natural-origin colorant and photoprotective agent in tinted moisturizers, foundations, and anti-aging products where synthetic UV filters may be less desirable for consumers.

In pharmaceutical research and specialty drug delivery, melanin is evaluated as a carrier matrix due to its binding affinity for certain active compounds and its inherent biological compatibility.

Hair care formulators also source melanin for color-restoration and UV-protective hair treatments. Melanin is supplied as a dark brown to black fine powder with varying particle size and solubility.

Food-grade and cosmetic-grade specifications are the most commonly available, with purity levels and sourcing documentation typically required by buyers in highly regulated global markets.

Natural-source material from cephalopod ink is the most established commercial form, though biotechnology-derived grades are increasingly available to meet modern sustainability requirements.
