Overview

Polyisobutene is a highly viscous liquid ingredient that has several applications. One main application is its ability to form films, which makes it great for use in lip glosses designed for long wear times.

This ingredient is also known for adding shine to products – another advantage for use in lip products. Polyisobutene is a stringy material that can control viscosity, as well. Added to skincare formulas, it will dramatically increase the thickness.

Finally, this ingredient also acts as a binding agent, where it improves the stability of pigments and holds them to the skin where the product is applied.
