Chemworld International manufactures and supplies solvent dyes to industrial buyers across the United States and internationally. Solvent dyes are non-polar, oil-soluble colorants that dissolve readily in organic solvents, oils, waxes, and plastics, without requiring water or ionic chemistry for application. This makes them uniquely suited for coloring non-aqueous systems such as plastics, petroleum products, lubricants, wood stains, printing inks, candles, and waxes.
Our solvent dye portfolio covers over 45 shades including blacks, blues, greens, reds, violets, and yellows, plus specialty Vat Red 41 and Vat Violet 3 grades. Key industry staples such as Solvent Black 3, Solvent Red 24, Solvent Yellow 14, and Solvent Blue 35 are stocked for immediate shipment.
The color shades displayed should only be considered a representation of the indicated dye or pigment. Actual color can depend on varying factors, including the desired application. Product samples are recommended for testing before use and/or purchase.
A solvent dye is an oil-soluble colorant that dissolves in organic solvents, hydrocarbons, oils, and plastics without requiring water. Unlike pigments (which are insoluble particles) or water-soluble dyes, solvent dyes create transparent, vibrant colors in non-aqueous systems.
Solvent dyes produce fully transparent colors in plastics with excellent clarity — ideal for applications like colored transparent polycarbonate or acrylic. Pigments produce opaque or semi-opaque colors with higher lightfastness. The choice depends on whether transparency or opacity is required.
Not all solvent dyes are approved for food-contact use. Please specify your application when requesting a quote and our team will identify compliant options. For food, drug, and cosmetic colorants, see our FD&C Dyes and Lakes page.
Yes. We supply petroleum-grade solvent dyes commonly used for fuel identification and tax-marking of diesel, gasoline, and heating oil. Contact us with your fuel type and concentration requirements.
Compatibility varies by grade but most solvent dyes dissolve well in alcohols, ketones, esters, aromatic hydrocarbons, and aliphatic solvents. Technical data sheets for each grade list specific solubility parameters. Contact us for detailed TDS on your grade of interest.
Properly stored solvent dye powders have a shelf life of 2+ years. Store in a cool, dry location in sealed containers away from moisture and heat. Detailed storage guidance is provided on the Safety Data Sheet for each grade.
