What is Disperse Violet 26 CAS 6408-72-6?

Disperse Violet 26, also known as Solvent Violet 59, is an anthraquinone dye with molecular formula C26H18N2O4 and EINECS 229-066-0. It is supplied as a dark purple powder with a bright reddish-violet shade.

Can Disperse Violet 26 be used in high-temperature plastic processing?

Yes. Its anthraquinone structure gives it high thermal stability, and it is commonly described as stable above 260 C and in some polymer systems up to about 300 C. This allows use in extrusion, injection molding, and dope dyeing.

Does Disperse Violet 26 require a carrier for polyester dyeing?

At atmospheric pressure and lower temperatures, a carrier or swelling agent is usually needed because the dye has low water solubility. Under high-temperature/high-pressure or thermosol conditions, polyester dyeing can be performed without atmospheric-pressure carrier dyeing.

Which fibers and materials is Disperse Violet 26 suitable for?

It is used mainly for polyester, acetate, and polyamide fibers, as well as polyester blends. As Solvent Violet 59, it can also color thermoplastics and engineering plastics such as ABS, PC, and PS.

What fastness and solubility properties should formulators expect?

Disperse Violet 26 is insoluble in water but soluble in organic solvents and polymer matrices. It typically offers excellent light fastness around grade 7-8 and high migration resistance in polymers.

Disperse Violet 26 CAS 6408-72-6

Disperse Violet 26 CAS 6408-72-6 is a bright reddish-violet anthraquinone dye chemically defined as 1,4-diamino-2,3-diphenoxyanthracene-9,10-dione , functioning primarily as a high-fastness colorant in the high-temperature dyeing of polyester fibers and the sublimation transfer printing of synthetic textiles. Also recognized as C.I. 62025 or Solvent Violet 59 in polymer applications, this hydrophobic powder is utilized to impart brilliant violet shades with excellent thermal stability to acetate fabrics and serves as a polymer-soluble colorant in the mass coloration of engineering plastics like polystyrene and polycarbonate. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

Why Formulators Choose Violet 26

This isn’t just another purple powder. Here is why it is a preferred choice for high-end manufacturing:

Thermal Stability: It can withstand the high temperatures of extrusion and injection molding without breaking down or changing color. This makes it ideal for “dope dyeing” (coloring synthetic fibers during the spinning process).
Vibrant Clarity: It produces a transparent, clean violet hue with a distinct reddish undertone, avoiding the muddy look of cheaper mixes.
Versatility: It works equally well in coloring solid plastics (like ABS, PC, and PS) and synthetic textile fibers (PET/Polyester).

Key Application Fields

1. Textile Fiber Coloring (Dope Dyeing) This is a primary use case. Violet 26 is used in the mass coloration of Polyester (PET) fibers. Because it is added during the spinning phase, the color becomes part of the fiber itself, offering superior wash fastness compared to traditional bath dyeing.

2. Engineering Plastics It is widely used to color various resins, including:

Polystyrene (PS) & HIPS
ABS (Acrylonitrile Butadiene Styrene)
Polycarbonate (PC)
PMMA (Acrylic) It is often used to neutralize yellow tones in clear plastics or to create vibrant transparent violet shades.

3. Masterbatches It is a staple ingredient for color masterbatch producers looking for high-concentration pigments that disperse easily.

Safety and Precautionary Measures

Even though Violet 26 has a good safety profile for industrial use, proper handling is necessary to protect your workforce.

Dust Management: The powder is fine and can generate dust. Use local exhaust ventilation to keep the air clean.
PPE: Operators should wear dust masks, safety glasses, and gloves. Avoid direct skin contact to prevent temporary staining.
Ingestion/Inhalation: Do not eat, drink, or smoke in the work area. If dust is inhaled, move to fresh air immediately.

For additional textile colorant options, see Vat Blue 18 and Acid Orange 67.

Storage and Handling Conditions

To maintain the dye’s strength and preventing moisture absorption:

Sealed Storage: Keep containers (fiber drums or cartons) tightly sealed.
Environment: Store in a cool, dry, and ventilated area.
Contamination: Keep away from strong oxidizing agents.
Shelf Life: typically 5 years when stored correctly in original packaging.
