HEXAMETHYLENEDIAMINE/MDI COPOLYMER

Description

Hexamethylenediamine/MDI copolymer is a synthetic ingredient used in various skincare and cosmetic formulations. This copolymer is formed through the reaction of hexamethylenediamine and methylene diphenyl diisocyanate (MDI), resulting in a versatile polymer with unique properties beneficial for skin applications.

The copolymer functions primarily as a film-forming agent, creating a thin, flexible layer on the skin's surface. This film helps to improve the texture and feel of skincare products while also providing a protective barrier against environmental stressors. Additionally, it aids in the even distribution and adherence of other active ingredients within a formulation.

Hexamethylenediamine/MDI copolymer is known for its water-resistance properties, making it particularly useful in long-wearing and water-resistant cosmetic products such as sunscreens, foundations, and mascaras. It also contributes to the overall stability and consistency of formulations, enhancing their shelf life and performance.

While generally considered safe for topical use, individuals with sensitive skin or specific allergies should perform a patch test before using products containing this ingredient. As with any synthetic polymer, its use is regulated in cosmetic formulations to ensure safety and efficacy.
