Hydrogenated Polyisobutene (1400)

Hydrogenated Polyisobutene (1400)

High molecular weight hydrocarbon emollient used to build structure, body, and sensory richness in cosmetic formulations.

INCI Name: Hydrogenated Polyisobutene

Appearance: Clear, viscous liquid

Solubility: Oil-soluble

Function: Emollient, texture enhancer, film former, viscosity builder

Hydrogenated Polyisobutene (1400) is a high-viscosity synthetic hydrocarbon widely used in cosmetic formulations where texture, payoff, and sensory performance are important. It helps create rich, substantial formulations while maintaining excellent stability and compatibility with a broad range of cosmetic ingredients.

Its high molecular weight contributes body and structure to anhydrous systems, making it particularly useful in products that require cushion, adherence, and long-lasting sensory performance. Hydrogenated Polyisobutene is frequently incorporated into lip products, color cosmetics, treatment products, and specialty skincare formulations.

Supplied as a cosmetic raw material for formulation use.

What It Does

Hydrogenated Polyisobutene (1400) enhances the texture and performance of cosmetic formulations by contributing body, viscosity, and a smooth sensory profile. Its high molecular weight allows it to improve formulation structure while helping products feel richer and more substantial during application.

Key Benefits

• Provides body and structure to anhydrous formulations.
• Enhances product payoff and sensory performance.
• Contributes gloss and richness without excessive greasiness.
• Improves substantivity and wear characteristics.
• Excellent oxidative stability.
• Compatible with oils, esters, waxes, and silicones.

Typical Use Levels

• 2–10% — Texture enhancement
• 10–40% — Emollient and structure-building systems
• 20–100% — Anhydrous cosmetic bases

How to Incorporate

• Add directly to the oil phase.
• Can be blended with oils, waxes, esters, hydrocarbons, and silicones.
• May be heated during processing if required.

Common Applications

• Lip glosses
• Lip oils
• Lipsticks
• Balms and salves
• Color cosmetics
