PEI-45

Description

PEI-45, or Polyethylenimine-45, is a versatile synthetic polymer widely used in haircare formulations. This cationic compound possesses a high molecular weight and multiple amino groups, giving it unique properties that make it valuable in various hair treatments and styling products.

PEI-45 acts as an effective conditioning agent, forming a protective film on hair strands to reduce friction and improve manageability. Its positively charged nature allows it to adhere to negatively charged hair surfaces, providing long-lasting effects. This ingredient is particularly beneficial for damaged or chemically treated hair, as it can help repair and strengthen the hair shaft.

In haircare formulations, PEI-45 enhances the distribution and deposition of other active ingredients, improving overall product efficacy. It also contributes to increased hair volume and body, making it a popular choice in volumizing and styling products. Additionally, PEI-45 exhibits heat-protective properties, shielding hair from thermal damage during styling.

While generally considered safe for use in haircare products, some individuals may experience scalp sensitivity to high concentrations of PEI-45. As with any hair care ingredient, it is essential to follow recommended usage guidelines and perform patch tests when introducing new products containing this polymer.
