Mibk

Product Description

Our MIBK is high-purity cosmetic-grade methyl isobutyl ketone from direct factory supply, refined to Typical GC specifications with batch COA traceability for solvent and denaturant formulators.

This low-viscosity ketone solvent dissolves nitrocellulose and film-forming resins, volatilizes rapidly in manicure preparation systems, and functions as an ethanol denaturant in alcohol-based cosmetic bases where locally permitted.

CosIng-listed MIBK (4-methylpentan-2-one) meets industrial nail-care and fragrance-solvent demand, offering selective solvation depth beyond generic alcohol or ester carriers with verified purity documentation.

Key Benefits & Applications

MIBK delivers high-purity ketone solvation for formulators building manicure preparation, alcohol denaturant, and industrial cosmetic solvent systems.

• Resin dissolution: Dissolves nitrocellulose and film polymers in manicure preparation and lacquer processing systems.
• Volatile carrying: Low-viscosity solvent enables fast-evaporating action in nail prep and fragrance dispersion bases.
• Alcohol denaturation: Renders ethanol unfit for consumption in cosmetic alcohol-based toner and aftershave formulations.
• Selective solvation: Dissolves resin and polymer phases without excessive aqueous miscibility in industrial cosmetic solvent blends.

Formulation Guidelines

Use only where local regulations permit; verify EU Annex II prohibition before export; maintain flammable-solvent handling protocols and adequate ventilation during processing.

• Recommended use level: As primary solvent in nail prep systems; denaturant levels per local alcohol-denaturant regulations.
• Optimal formula pH: N/A — non-aqueous solvent systems only.
• Processing: Add to organic phase; use explosion-proof equipment; avoid heat and ignition sources.
• Compatibility: Miscible with ethanol, esters, and aromatic solvents in nail and fragrance systems.
• Caution: EU cosmetics prohibited; flammable vapor; not for aerosol use without regulatory review; verify export market compliance.
• Synergy: Pair BHT at 0.01–0.1% with MIBK solvent blends to stabilize dissolved resins in nail prep systems.
