PEG-8/SMDI COPOLYMER

Description

PEG-8/SMDI Copolymer is a synthetic ingredient widely used in skincare and cosmetic formulations. This water-soluble polymer is created through the reaction of polyethylene glycol (PEG-8) and saturated methylene diphenyl diisocyanate (SMDI). Its primary function is to act as a film-forming agent, providing a protective barrier on the skin's surface.

In skincare products, PEG-8/SMDI Copolymer enhances texture and improves the spreadability of formulations. It contributes to a smooth, non-greasy feel upon application, making it particularly useful in moisturizers, serums, and sunscreens. The ingredient also helps to stabilize emulsions and suspend particles in liquid formulations.

One of the key benefits of PEG-8/SMDI Copolymer is its ability to form a breathable film on the skin, which can help to lock in moisture and other beneficial ingredients. This property makes it valuable in products designed for long-lasting hydration or those intended to deliver active ingredients over an extended period.

While generally considered safe for use in cosmetics, individuals with sensitive skin should perform a patch test before incorporating products containing this ingredient into their routine.
