HYDROXYETHYL PEI-1500.

Valuable CAS - / SURFACTANT - CLEANSING

HYDROXYETHYL PEI-1500 is a versatile cationic polymer utilized for its multi-functional properties in personal care. It effectively acts as a cleansing agent while also providing significant conditioning, odor control, and film-forming benefits. Its structure allows it to interact positively with negatively charged surfaces, contributing to its efficacy.

Science

Mechanism of Action

As a cationic polymer, HYDROXYETHYL PEI-1500 is characterized by multiple positively charged amine groups along its molecular chain. This intrinsic charge enables it to form strong interactions with negatively charged biological surfaces, such as hair keratin and the skin's surface. These interactions facilitate cleansing by attracting impurities, provide conditioning effects, and contribute to film-forming properties that can enhance barrier function.
