Oil-soluble Dye FAQs
What is the shelf life of oil-soluble dyes?
Our oil-soluble dyes have a standard shelf life of 24 months when stored in their original packaging at temperatures between 10-30°C, away from direct sunlight and moisture. Liquid formulations should be protected from freezing.
Are oil-soluble dyes safe for cosmetic applications?
Yes, we offer special cosmetic-grade oil-soluble dyes that comply with FDA, EU, and ASEAN cosmetic regulations. These dyes undergo rigorous testing for heavy metal content and other contaminants to ensure safety in personal care products.
How do oil-soluble dyes differ from water-soluble dyes?
Oil-soluble dyes are chemically designed to dissolve in non-polar solvents (oils, fats, organic solvents) while water-soluble dyes dissolve in polar solvents (water, alcohols). Oil-soluble dyes generally offer better migration resistance in hydrophobic materials and superior lightfastness in many applications.
Can oil-soluble dyes be mixed to create custom colors?
Absolutely. Our oil-soluble dyes can be blended to achieve a wide spectrum of custom colors. We recommend conducting small-scale compatibility tests before full production, as some dye combinations may require specific solvent systems for optimal performance.
What safety precautions should be taken when handling oil-soluble dyes?
While our oil-soluble dyes are generally safe when handled properly, we recommend wearing protective gloves and eyewear to prevent skin contact and eye irritation. Ensure adequate ventilation when working with powder forms to avoid inhalation of dust particles.
