Full Description
Hydrogenated polyisobutene (CAS 68937-10-0) is a saturated synthetic hydrocarbon polymer made by hydrogenating a polymer of isobutene. It is used in cosmetic and personal-care formulations as an emollient, occlusive, and viscosity-building base.
Frequently Asked Questions
What is hydrogenated polyisobutene made from?
Hydrogenated polyisobutene (CAS 68937-10-0) is a saturated synthetic hydrocarbon polymer made by polymerizing isobutene and then hydrogenating the polymer. The hydrogenation removes residual unsaturation, giving a stable, fully saturated hydrocarbon.
What is hydrogenated polyisobutene used for?
It is used in personal-care formulations as an emollient and spreading/gloss agent in skin and lip care, as an occlusive moisture-barrier film, and as a viscosity-building base in anhydrous systems. It is common in lip gloss for its cling and shine.
What grades or viscosities of hydrogenated polyisobutene are available?
It is supplied across a range of viscosity grades, from lighter spreading fluids to heavier, higher-cling bodies. Specify your target viscosity when requesting a quote; the CoA confirms the lot specification.
What is the HS code for hydrogenated polyisobutene?
It classifies under HS 3902.20 (polyisobutylene). Confirm destination-country tariff treatment with your customs broker; RawSource supplies commercial documentation per shipment.
What bulk packaging and MOQ apply to hydrogenated polyisobutene?
RawSource supplies it in drums and totes for manufacturing use. MOQ, lead time, and pricing are quote-based — request a bulk quote with your target viscosity grade and volume; a CoA and SDS accompany the order.
