Polyisobutene and Hydrogenated Polyisobutene are homopolymers of isobutene. These ingredients are produced in a wide range of molecular weights. Polybutene is a chemically related cosmetic ingredient previously determined to be safe as used in cosmetic products. Polyisobutene is used in cosmetic products as a binder, film former, and nonaqueous viscosity-increasing agent. Hydrogenated Polyisobutene functions as a skin-conditioning agent-emollient and nonaqueous viscosity-increasing agent with a…

Cell transformation and promoter activity of insulation oils in the Syrian hamster embryo cell and in the C3H/10T1/2 mouse embryo fibroblast test systems.
TLDR
In experiments with the Syrian hamster embryo cell transformation assay, it was found that C15-C18 alkylbenzenes were the most potent inducers of transformation, followed by low-viscosity and residual mineral oils, which were found to be more potent than the polyisobutylene-based fluid.
