PEI-2500
Description
PEI-2500, or Polyethylenimine 2500, is a versatile synthetic polymer widely used in skincare and cosmetic formulations. This high molecular weight compound is characterized by its cationic nature and branched structure, which contribute to its unique properties in personal care products.
In skincare applications, PEI-2500 functions primarily as a film-forming agent and conditioning polymer. It forms a thin, protective layer on the skin's surface, helping to improve moisture retention and enhance the overall feel of products. The ingredient's positive charge allows it to interact effectively with negatively charged skin proteins, promoting better adhesion and longer-lasting effects.
PEI-2500 also serves as a stabilizer and thickening agent in various formulations, improving product texture and consistency. Its ability to form complexes with other ingredients makes it useful in controlled-release systems, potentially enhancing the efficacy of active ingredients.
While generally considered safe for cosmetic use, formulators should be mindful of potential irritation in sensitive individuals and use appropriate concentrations. PEI-2500's multifunctional nature makes it a valuable ingredient in a range of skincare products, including moisturizers, serums, and masks.
