BIS-ADAMANTYL PEG-800 DICARBOXAMIDE.

Valuable CAS - / FILM FORMING, HUMECTANT, SKIN PROTECTING, VISCOSITY CONTROLLING

A sophisticated, high-molecular-weight polymer engineered for 'Auto Repair Technology' in high-performance skincare. It creates an adaptive, self-healing shield that maintains film integrity even under the mechanical stress of daily facial expressions.

Science

Mechanism of Action

This molecule functions as a structural 'stopper' within slide-ring (polyrotaxane) polymer architectures. By capping PEG-800 chains with adamantyl groups via dicarboxamide linkages, it creates a flexible molecular network that allows the skin's surface film to glide and recover from micro-scratches or deformations without breaking the protective barrier.
