BUTYL METHACRYLATE/ACRYOYLOXY PG METHACRYLATE COPOLYMER.

Valuable CAS 1431551-12-0 / FILM FORMING

A biomimetic polymer that creates a breathable, protective film on skin while enhancing moisture retention and barrier function. This sophisticated copolymer mimics natural phospholipid structures to deliver superior skin conditioning benefits across all skin types. Its dual-action design combines humectant properties with structural integrity for long-lasting protection.

Film former Skin conditioning Barrier enhancement Active delivery enhancer

Science

Mechanism of Action

Forms a biomimetic film that replicates phospholipid membrane structures on skin's surface. The acryloyloxy PG component provides moisture-binding capability and skin affinity, while the butyl methacrylate segment ensures film durability and wash-off resistance, creating a breathable barrier that reduces transepidermal water loss.
