Also known as
HPIB Hydrogenated PIB Polyisobutylene, hydrogenated Panalane Parleam
Compatibility
Works well with:
Dimethicone Cyclopentasiloxane Isododecane Squalane Cetyl Alcohol Mineral Oil
Hydrogenated Polyisobutene is broadly compatible with most cosmetic oil-phase ingredients, silicones, and waxes. It is water-insoluble and must be incorporated into the oil phase of emulsions. No significant reported incompatibilities with common cosmetic raw materials.
Formulation notes
Hydrogenated Polyisobutene is a highly refined, synthetic hydrocarbon polymer used as a lightweight to medium-weight emollient that imparts a silky, non-greasy skin feel with excellent spreadability. It is valued as a mineral oil and silicone alternative due to its colorless, odorless, and oxidatively stable profile. Considered low comedogenicity and generally well-tolerated; it is widely used in lip products, foundations, sunscreens, and skin care formulations.
