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… 
Safety Assessment of Polyene Group as Used in Cosmetics
The Panel concluded that polyenes were safe in cosmetics in the present practices of use and concentration described in this safety assessment.


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.
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.
Drug Release Properties of the Microcapsules of Adriamycin Hydrochloride with Ethylcellulose Prepared by a Phase Separation Technique
AbstractAdriamycin hydrochloride was microencapsulated with ethylcellulose by a phase separation method to develop a prolonged release dosage form. Polyisobutylene (PIB) was used as a
Nuclear Magnetic Resonance Absorption in Polyisobutylene
The proton magnetic resonance absorption in polyisobutylene has been measured over the temperature range - 196°C to 90°C. The unusually large width of the absorption line at the lowest temperatures
Prevention of plant injury by cabbage gall midge (Contarinia nasturtii Kieffer) and onion thrips (Thrips tabaci Lindemann) using emulsions of polyisobutylene
Non ionogenic emulsions of the artificial rubber polymer polyisobutylene were effective for control of the cabbage gall midge, Contarinia nasturtii, on cauliflower and cabbages under both field and
