Polyoxymethylene Melamine

What is Polyoxymethylene Melamine?

Polyoxymethylene melamine is a cross-linked synthetic polymer made from melamine and formaldehyde units, resulting in a durable resin. Primarily used in nail polishes, mascaras, eyeliners, and hair styling products within the cosmetics industry. It functions by depositing a thin, flexible film on skin, hair, or nails as the product dries, which helps anchor pigments, resist moisture, and maintain product integrity over time. This film-forming action supports extended wear without flaking or smudging, making it suitable for formulations needing enhanced performance. The ingredient's structure allows it to create a breathable barrier that adheres well to surfaces while remaining compatible with other cosmetic components.
