KEMAT polybutene is used in the formulation of eye makeup, lipstick and skin care products because it is a pure and clear, non-drying, sticky liquid, light in colour.  It is safe for use in skin applications, it is non-skin irritating, non-drying and hydrophobic.  It is also non-comedogenic (prevents blocked pores) and non-toxic.

Polyisobutene dries to form a thin coating on the skin and is used to hold together the ingredients of a compressed cake.  Hydrogenated Polyisobutene acts as a lubricant on the skin’s surface, which gives the skin a soft and smooth appearance.

In cosmetics and personal care products PIB functions as a:

  • binder: to hold together the ingredients of a compressed cake or tablet.
  • epilating agent: to be heated, applied to the skin and stripped off quickly to remove unwanted hair.
  • viscosity increasing agent (non-aqueous): to increase the thickness of the oil portion of cosmetic products.

KEMAT offers low molecular weight conventional polybutenes: Polybut™ as well as medium and high polyisobutenes: Polybol™.
