Common Name(s): Polyurethane-69,polyurethane-69,cosmetic functional ingredient,established active

CAS Number: N/a

DESCRIPTION

What It Does: Provides film formation, viscosity modification, texture enhancement, or biodegradable encapsulation through polymer chain architecture.

Why It's Used: Polyurethane-69 is selected for polyurethane film mechanics — the polyol/isocyanate hard-soft segment ratio of polyurethane-69 provides the specific tensile strength and elongation at break that delivers wear-resistant cosmetic film unachievable with pure acrylic polymers.

How It Works: Chain entanglement above c* provides viscosity; film formation above tg; functional monomers provide adhesion or charge; biodegradable ester backbone hydrolyses to harmless monomers.
