Downstream process integration

• Added during the main dyeing stage after scouring and before aftertreatment in both batch and continuous operations

Final product types

• Acrylic filament yarn
• Acrylic knitwear and woven fabrics
• Carpet and furnishing textiles
• Fleece and outdoor apparel

2. Paper Industry – Tissue and Specialty Papers

Producers in the paper sector use Basic Blue 17 as a substantive dye for tinting high-brightness tissue, crepe papers, and security papers. The dye imparts uniform blue coloration while maintaining necessary paper strength and smoothness. Formulators carefully dose the material to avoid bleed-through and color migration during conversion and end-use.

Industry compliance standards

• EN 646 (Color fastness for paper and board)
• FDA 21 CFR 176.170 (indirect food contact pigments for paper)
• ISO 187 (Conditioning of paper and board)

Typical usage ratio

• 0.03–0.18% pigment-to-paper pulp by weight; adjusted based on required shade and pulp composition

Downstream process integration

• Introduced into wet-end at the pulp slurry stage, before sheet forming and pressing

Final product types

• Colored facial tissues
• Crepe wrapping paper
• Security and banknote paper
• Decorative napkins

3. Leather Finishing and Wet-End Coloration

Basic Blue 17 plays a specialist role in the wet-end coloration of chrome-tanned and vegetable-tanned leathers, supplying vibrant blue shades for fashion, automotive, and upholstery applications. Technicians carefully manage dye penetration, surface uniformity, and compatibility with downstream finishes and treatments. The dye selection considers migration resistance and ecological impact in end-use settings.

Industry compliance standards

• EN 71-3 (Migration of elements for consumer products)
• ISO 11640 (Leather color fastness to rubbing)
• Leather Working Group (LWG) standards – chemical management modules

Typical usage ratio

• 0.1–2.5% dye solution per wet leather weight; adjusted depending on skin thickness and tanning chemistry

Downstream process integration

• Added during drum dyeing or paddling after neutralization and before fatliquoring

Final product types

• Footwear uppers
• Fashion leather goods (belts, wallets, handbags)
• Upholstery hides
• Automotive leather interiors

4. Hair Dye Formulation

Major hair dye brands employ Basic Blue 17 in the compounding of semi-permanent and direct-application hair color products. The raw material delivers vivid blue undertones and helps balance shade profiles. Chemists formulate with pH stabilizers and surfactants, ensuring safe deposition on keratin fibers and compliance with cosmetic regulations. Dyes must show predictable wash-fastness, minimal scalp irritation, and compatibility with auxiliary agents.

Industry compliance standards

• EU Cosmetics Regulation (EC) No 1223/2009 (Annex IV permitted colorants)
• US FDA 21 CFR 73.2396 (hair dye color additive listing)
• GB 7916 (Chinese cosmetics safety guidelines)

Typical usage ratio

• 0.2–2.0% by weight in final dye cream or liquid; formulation varies by intended shade intensity and carrier composition

Downstream process integration

• Dissolved in aqueous color base, blended with conditioning and oxidizing ingredients before packaging

Final product types

• Semi-permanent hair creams
• Direct dye color gels
• Color-depositing hair masks
• Blue-tinted hair rinses

5. Ink Manufacturing – Water-Based Printing Inks

Ink formulators use Basic Blue 17 as a bright cationic dye component for water-based flexographic and gravure ink systems, especially for packaging and security printing. Mixing the product with compatible binders and stabilizers allows fine-tuning of viscosity, print density, and substrate adhesion. Precise quality assessment targets batch-to-batch color consistency and compliance with migration limits for packaging applications.

Industry compliance standards

• Swiss Ordinance on Materials and Articles in Contact with Food (SR 817.023.21 – Annex 10A)
• EuPIA Exclusion Policy for Printing Inks
• ISO 2836 (Resistance to solvents, fats, and oils of printed material)

Typical usage ratio

• 2–10 g/kg in water-based ink formulations; adjusted for shade strength, print speed, and substrate type

Downstream process integration

• Dispersion into aqueous phase during initial ink mixing, before milling and let-down processing

Final product types

• Flexographic inks for flexible food packaging
• Security inks for tax stamps and labels
• Coding and marking inks
• Decorative carton printing inks

6. Plastic Coloring – Polyacrylonitrile (PAN) and Nylon

Compounders and masterbatch producers add Basic Blue 17 during the melt-spinning or solution dyeing steps of polyacrylonitrile and nylon polymers. This application provides deep, uniform color throughout the cross-section, enhancing color stability and preventing migration. Colorists manage compatibility and dispersion, checking against physical property retention and downstream thermal stability.

Industry compliance standards

• ISO 2409 (Paints and varnishes cross-cut test – product adhesion for colored plastics)
• RoHS Directive 2011/65/EU (hazardous substances in electrical/electronic plastics)
