Polypropylene
What is Polypropylene?
Polypropylene is a durable thermoplastic polymer created by linking propylene monomers, sourced from petrochemical processes. In cosmetics, it serves as a white, odorless powder or resin primarily in solid or semi-solid items like lipsticks, eyeliner pencils, hair wax, and pressed powders. It works by forming a rigid yet flexible network that supports other components, preventing separation and enabling precise molding. This property allows it to increase product bulk without heaviness, while fine-tuning flow characteristics to ensure even gliding during application. Its chemical stability makes it ideal for long-lasting formulations exposed to body heat and friction.
