Polyisobutene is a general name for a wide range of aliphatic branched-chain polymeric hydrocarbons C56 –C856. It is a clear, colorless, odorless, viscous liquid with a good safety profile.
Polyisobutene is used in sun and skin care applications to leave a protective moisture barrier and produce a vibrant and emollient feel to the skin. It is compatible with lower viscosity and violates isoparaffins, and in combination with them, provides a luxurious feel and allows control of viscosity.
Used in lip products, Polyisobutene improves wear and imparts a sheen. It has excellent spreading properties and can be combined with other aliphatic branched chain hydrocarbons and other ingredients to customize desired properties.
Polyisobutene is highly occlusive and provides barrier properties with long-lasting wear. It exhibits interesting properties and is compatible with other ingredients (silicones and many other cosmetic fluids), making it ideal for use in a wide variety of cosmetic and personal care applications.Functions
