Mek

Product Description

Green Stone Swiss supplies cosmetic-grade MEK (methyl ethyl ketone / butanone) under a direct factory model, with GMP-aligned quality control, batch documentation, and sample support for professional color-cosmetic and nail-care formulators.

MEK (C₄H₈O; CAS 78-93-3) is a volatile ketone solvent. CosIng lists solvent and perfuming functions; in practice it is selected to dissolve resins and film-forming polymers, lower lacquer viscosity, and support rapid drying in nail polish, top coats, and related coating systems—not as a skin-care bioactive.

It remains a technical solvent option for brands and OEM/ODM labs building conventional nail lacquer chassis that require fast evaporation and strong solvency for nitrocellulose and acrylic systems.

Product Specification

• INCI Name: MEK

• Suggested pH: Not typically pH-adjusted as a neat solvent; confirm in finished lacquer systems
• Storage: Store sealed, cool, and well ventilated; keep away from ignition sources (flammable liquid)

Key Benefits & Applications

MEK is a high-purity volatile ketone solvent for professional nail lacquer and coating formulations.

• Provides strong solvency for resins and film formers used in nail polish and top-coat systems
• Supports viscosity reduction and fast evaporation for smoother application and quicker dry-down
• Suitable for nail polishes, top coats, base coats, and selected remover or thinning systems
• Compatible with many nitrocellulose and acrylic lacquer chassis when screened in the full formula
• Typical use level: Formulation-dependent; finalize by product type, drying profile, and regional assessment

Formulation Guidelines

Use these process and handling notes when incorporating MEK into nail lacquer and related solvent systems.

• Suggested Use Level: Formulation-dependent; balance solvency, dry time, and regulatory limits for the finished product type
• Addition: Blend into the solvent phase under controlled, ventilated conditions; avoid open flames and static ignition sources
• Process: Monitor viscosity and evaporation rate when adjusting resin solids; confirm film clarity, adhesion, and gloss after drying
• Compatibility: Screen with plasticizers, resins, pigments, and secondary solvents in the full lacquer; verify settling and blush resistance
• Safety / Packaging: Use solvent-rated equipment and containers; label and store as a flammable liquid per site SOP
• Combine with Toluene in conventional multi-solvent nail lacquer systems where regional rules and brand “free-from” policies allow.
