1.Product Description
Achieve Brilliant, Heat-Stable Violet Coloration with Solvent Violet 13 – The Premium Anthraquinone Dye for Plastics, Fibers, and Cosmetics.
Solvent Violet 13, internationally designated as C.I. 60725 and commonly known as D&C Violet No. 2 in cosmetic applications, is a high-performance anthraquinone-based solvent dye renowned for its brilliant bluish-violet hue, exceptional heat resistance, and outstanding lightfastness . This sophisticated dye features a unique 1-hydroxy-4-(p-toluidino)anthraquinone molecular structure that delivers superior thermal stability and excellent solubility in organic solvents and polymer matrices .
What distinguishes Solvent Violet 13 from conventional solvent dyes is its exceptional combination of heat resistance, lightfastness, and versatility. With a melting point of 186°C and excellent stability during melt processing, this dye maintains its vibrant color through demanding injection molding, extrusion, and fiber spinning operations . Its lightfastness rating of 6-7 (on an 8-point scale) ensures long-lasting color integrity in outdoor and prolonged-use applications .
Key differentiators:
Anthraquinone Chemistry: Provides superior thermal stability and lightfastness compared to azo-based alternatives, with excellent migration resistance .
Exceptional Heat Resistance: Withstands processing temperatures up to 200-300°C, suitable for engineering plastics and polyester fiber applications .
Brilliant Bluish-Violet Shade: Delivers a clean, transparent bluish-violet hue with excellent color strength and brilliance .
Broad Application Range: Suitable for plastics, polyester fibers, cosmetics, coatings, and specialty applications like pyrotechnics .
Regulatory Compliance: Approved for cosmetic use as D&C Violet No. 2 in nail polishes, hair dyes, and makeup products .
