Kester Wax K-82p (Hydroxy Polyester)
What is Kester Wax K-82p (Hydroxy Polyester)?
Kester Wax K-82P, identified as hydroxy polyester, is a synthetic wax formed by polymerizing hydroxy fatty acids like 12-hydroxystearic acid from castor oil sources. It falls into the emollient and wax category for cosmetics, where it acts primarily as a viscosity controller, film former, and emollient. In formulations, it builds structure in emulsions such as lotions and creams, enhances pigment adhesion in lipsticks and mascaras, and delivers a smooth, non-sticky barrier on skin. This ingredient supports product stability and spreadability, making it suitable for color cosmetics, hair styling aids, and personal care items needing enhanced body without added greasiness. Its properties enable consistent texture across various formulations.
