PEI-15

Description

PEI-15, or Polyethylenimine-15, is a versatile synthetic polymer used in various haircare formulations. This cationic compound is known for its exceptional binding properties and film-forming capabilities, making it a valuable ingredient in hair styling and treatment products.

PEI-15 functions as a conditioning agent, providing a smooth and silky feel to hair strands. Its positive charge allows it to adhere effectively to negatively charged hair surfaces, creating a protective layer that helps reduce frizz and improve manageability. This ingredient is particularly beneficial for damaged or chemically treated hair, as it can help temporarily seal split ends and smooth the hair cuticle.

In hair styling products, PEI-15 contributes to hold and shape retention, making it useful in products like gels, mousses, and hairsprays. It also enhances the substantivity of other active ingredients, improving their longevity on the hair shaft. While PEI-15 offers numerous benefits, formulators must carefully balance its concentration to avoid potential build-up or heaviness, especially on fine hair types. As with any hair care ingredient, individual results may vary based on hair type and condition.
