Solvent Blue 35 (C.I. 61554, Sudan Blue II, CAS 17354-14-2) — Application Areas

Solvent Blue 35 (C.I. 61554, also known as 1,4-bis(butylamino)anthraquinone or Sudan Blue II; CAS 17354-14-2) is a solid, oil-soluble anthraquinone-class blue colorant with a molecular weight of 350.45 g/mol and a melting range of 120–122 °C. Its solubility in aromatic and aliphatic organic media, combined with thermal stability in polymer matrices up to approximately 250 °C, has supported its use across industrial coloration programs for several decades. Typical application areas are summarized below.
• Industrial Polymer & Resin Coloration
Oil-soluble anthraquinone blue colorants of this class are used in the coloration of styrenic, acrylic, and engineering thermoplastic resins. The thermal stability of Solvent Blue 35 in polymer matrices up to approximately 250 °C, combined with strong affinity for the molten polymer phase, has supported its use in melt-compounding workflows that have been established in industrial color chemistry for several decades. Polymer–dye compatibility, dispersion behavior, and end-product qualification are the buyer's responsibility.
End Products: polystyrene (PS) injection-moulded parts, polycarbonate (PC) sheet, poly(methyl methacrylate) (PMMA) extrusions, high-impact polystyrene (HIPS) housings, acrylonitrile-butadiene-styrene (ABS) components.
• Industrial Wax, Candle & Lubricant Coloration
Solvent Blue 35 is soluble in molten paraffin and stearic-acid wax systems, and in aliphatic petroleum lubricants, allowing uniform blue tinting at low addition levels. This dye class has been used in industrial wax, candle, and lubricant coloration for several decades. Selection, addition level, and lot qualification against the specific wax or lubricant base are determined by the buyer.
End Products: industrial candles, paraffin wax blocks, bulk scented-wax bases, specialty lubricating oils, grease and tinting concentrates.
• Solvent-Based Coatings & Printing Inks
Anthraquinone-class solvent dyes are used in solvent-based coating and gravure printing-ink formulations where high transparency and water insolubility are required. Solvent Blue 35 dissolves readily in alcohol, toluene, and acetone-based vehicles, giving a clean blue shade suitable for transparent finishes. Compatibility with binder system, additive package, and substrate must be qualified by the formulator.
End Products: solvent-based industrial coatings, gravure printing inks, transparent lacquer finishes, solid colorant masterbatches for ink production.
• Industrial Hydrocarbon-Fluid Coloration (Non-Identification Use)
Oil-soluble anthraquinone blue colorants have been used in general industrial hydrocarbon-fluid coloration for several decades. Any jurisdiction-specific fuel identification or marking program is governed by separate regulations and intellectual-property frameworks; selection, qualification, and compliance for any such program are entirely the buyer's responsibility. Material is supplied with a lot-specific Certificate of Analysis and Safety Data Sheet; suitability for any specific finished formulation is the responsibility of the end formulator.
End Products: industrial hydrocarbon coloration concentrates, blue-tinted process fluids, solvent-based colored stripper formulations, non-identification B2B colored hydrocarbon programs.
