HDI/PEI-45/SMDI CROSSPOLYMER

Description

HDI/PEI-45/SMDI Crosspolymer is a synthetic polymer used in various skincare and cosmetic formulations. This complex ingredient is formed by crosslinking hexamethylene diisocyanate (HDI), polyethyleneimine-45 (PEI-45), and saturated methylene diphenyldiisocyanate (SMDI). The resulting compound is a film-forming agent that offers multiple benefits in skincare products.

The crosspolymer functions primarily as a texture enhancer and stabilizer, improving the overall feel and consistency of formulations. It helps create a smooth, silky texture in creams, lotions, and serums while also contributing to their long-term stability. HDI/PEI-45/SMDI Crosspolymer has the ability to form a breathable film on the skin's surface, which can help reduce transepidermal water loss and improve skin hydration.

Additionally, this ingredient acts as an effective binder for other components in the formulation, ensuring even distribution of active ingredients throughout the product. It also aids in the controlled release of active ingredients, potentially enhancing their efficacy. The polymer's film-forming properties can provide a temporary tightening effect on the skin, making it useful in anti-aging and firming products.
