Toluene

Product Description

Our Toluene is high-purity cosmetic-grade solvent from direct factory supply, refined to Typical GC specifications with batch COA traceability for nail lacquer and hair dye formulators.

This aromatic hydrocarbon dissolves nitrocellulose and film-forming resins, volatilizes at controlled rates for fast-dry nail films, and functions as an authorized EU Annex III solvent in hair dye systems within defined limits.

CosIng-listed toluene meets professional nail enamel and oxidative hair color demand, offering low-viscosity solvation depth beyond generic industrial-grade aromatic solvents with unverified cosmetic compliance.

Key Benefits & Applications

Toluene delivers high-purity aromatic solvation for formulators building nail lacquer, hair dye, and professional solvent-based cosmetic systems.

• Resin solvation: Dissolves nitrocellulose and film-forming resins in nail lacquer bases at up to 25% w/w.
• Fast-dry volatilization: Controlled evaporation enables quick-set nail enamel films in professional lacquer systems.
• Formulation stability: Limits resin oxidation during bulk storage and high-shear lacquer processing.
• EU-compliant solvent: Authorized solvent vehicle for oxidative hair dye bases at ≤4% w/w per Annex III.

Formulation Guidelines

Use within EU Annex III limits; nail lacquer max 25% w/w; oxidative hair dye max 4%; non-oxidative hair dye max 2%; no aerosol spray applications for hair dye.

• Recommended use level: Up to 25% in nail lacquer; ≤4% in oxidative hair dye; ≤0.1% as trace in other ingredients.
• Optimal formula pH: N/A — non-aqueous solvent systems only.
• Processing: Add to organic phase; use explosion-proof equipment; maintain ventilation during filling.
• Compatibility: Compatible with ethyl acetate, butyl acetate, and nitrocellulose in lacquer systems.
• Caution: Flammable; avoid heat and ignition sources; not for aerosol hair dye dispensers per EU limits.
• Synergy: Pair BHT at 0.01–0.1% with toluene lacquers to protect nitrocellulose films from oxidative yellowing.
