Description

Aluminum, 6-Hydroxy-5-[(2-Methoxy-5-Methyl-4-Sulfophenyl)Azo]-2-Naphthalenesulfonic Acid Complex is a high-performance, water-soluble metal complex dye, also known as an aluminum lake pigment. This compound is valued for its excellent lightfastness, heat stability, and vibrant color properties, making it a reliable choice for demanding industrial applications. It is primarily sought after by manufacturers in the cosmetics, inks, plastics, and specialty coatings industries where consistent, non-migratory coloration is critical.

Application

• Cosmetic Colorant: Used in lipsticks, eye shadows, blushes, and other decorative cosmetics as a stable, non-toxic pigment.
• Printing Inks: Provides vivid and durable coloration for packaging, security, and specialty printing applications.
• Plastics and Polymers: Imparts color to a variety of plastic resins, offering good dispersion and thermal stability during processing.
• Industrial Coatings: Employed in paints and coatings where weather resistance and color consistency are required.
• Paper Coloring: Used for surface coating and tinting of specialty papers.
• Artist's Colors: A component in high-grade artist paints and pigments due to its purity and color strength.
