Description

Hydrogenated Polyisobutene CAS NO 68937-10-0 is a fully saturated, synthetic hydrocarbon polymer derived from the catalytic hydrogenation of polyisobutene. This process yields a material prized for its exceptional oxidative stability, low color, and odorless properties, making it a superior alternative to traditional mineral oils and polybutenes. It serves as a versatile, non-greasy emollient and solvent with excellent spreading characteristics and compatibility with a wide range of cosmetic and industrial ingredients. Key industries that rely on this high-performance fluid include personal care, pharmaceuticals, and specialty lubricants.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emollient, solvent, and viscosity modifier in lipsticks, lip balms, foundations, sunscreens, and hair care products, providing a smooth, non-tacky feel.
• Pharmaceutical Topicals: Used as a base or carrier fluid in ointments, creams, and transdermal patches due to its chemical inertness and skin compatibility.
• Specialty Lubricants & Greases: Functions as a high-performance base oil or thickener component in lubricants requiring high stability, wide temperature range performance, and clean operation.
• Plastic & Rubber Processing: Employed as a plasticizer and processing aid to improve flexibility and reduce viscosity during the manufacturing of various polymers.
• Adhesives & Sealants: Serves as a tackifier and plasticizing agent, enhancing adhesion and flexibility while improving aging properties.
• Industrial Release Agents: Used in mold release applications for plastics, rubber, and die-casting where a non-staining, non-migrating fluid is required.

Quality Control

Our Hydrogenated Polyisobutene is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for viscosity, color, unsaturation (iodine value), and stability. Certificates of Analysis (COA) documenting key parameters are available upon request. We can supply grades suitable for cosmetic (meeting relevant purity expectations), industrial, and technical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and open flames. For long-term storage, blanketing with an inert gas such as nitrogen is recommended to maintain product quality.
