BIS-METHOXY PEG-13 PEG-438/PPG-110 SMDI COPOLYMER

Description

BIS-METHOXY PEG-13 PEG-438/PPG-110 SMDI Copolymer is a synthetic polymer used in advanced skincare formulations. This multifunctional ingredient serves as a film-former, emollient, and viscosity control agent, contributing to the texture and performance of various skincare products.

The copolymer is composed of polyethylene glycol (PEG) and polypropylene glycol (PPG) segments, combined with methoxy end-capping and SMDI (saturated methylene diphenyl diisocyanate) linkages. This unique structure allows it to form a flexible, breathable film on the skin's surface, which helps to lock in moisture and protect against environmental stressors.

In skincare formulations, BIS-METHOXY PEG-13 PEG-438/PPG-110 SMDI Copolymer enhances product stability and improves the overall sensory experience. It contributes to a smooth, non-greasy feel and aids in the even distribution of active ingredients. The polymer's film-forming properties also make it useful in long-wearing makeup and sunscreen formulations, where it can help improve water resistance and durability.

This ingredient is generally well-tolerated by most skin types and is compatible with a wide range of other skincare ingredients, making it a versatile choice for formulators seeking to create high-performance skincare products.
