Description

Hydrogenatedpolyisobutene CAS NO 61693-08-1 is a fully saturated, branched hydrocarbon polymer derived from the catalytic hydrogenation of polyisobutene. This process yields a material prized for its exceptional oxidative stability, low color, and odorless nature, making it a superior alternative to mineral oils and other unsaturated hydrocarbons. It serves as a versatile base fluid, emollient, and viscosity modifier for formulators in the personal care, cosmetics, and specialty lubricants industries seeking high-performance, inert ingredients.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in lipsticks, lip balms, foundations, sunscreens, and hair care products, providing a non-greasy, silky feel.
• Skin Care Formulations: Used in creams, lotions, and ointments as a stable occlusive agent to enhance skin hydration and improve texture without irritation.
• Color Cosmetics: Serves as a pigment dispersant and binder in makeup, ensuring smooth application, even color payoff, and improved wear.
• Pharmaceutical Topicals: Employed as a base or carrier in ointments and dermatological preparations due to its chemical inertness and excellent skin compatibility.
• Specialty Lubricants: Functions as a high-stability base oil or viscosity index improver in synthetic lubricants, greases, and release agents for sensitive applications.
• Industrial Fluids: Used as a component in transformer oils, heat transfer fluids, and other functional fluids where thermal and oxidative stability are critical.
• Plastic & Rubber Additive: Acts as a processing aid and internal lubricant to improve flow properties and surface finish during polymer extrusion and molding.
