Description

Acid Red 414 is a synthetic, water-soluble azo dye belonging to the acid dye class, known for its bright and vivid red color. Its primary value lies in providing excellent color fastness and strong affinity for protein-based and polyamide fibers, ensuring durable coloration. This dye is essential for manufacturers in the textile, leather, and paper industries seeking reliable and consistent red shades for their products.

Application

• Primary dyeing and printing of nylon, silk, and wool textiles.
• Coloration of leather goods, including footwear, bags, and upholstery.
• Manufacturing of colored paper and paper products.
• Ink formulation for specialized inks and toners.
• As a colorant for certain types of cosmetics and personal care products (subject to regional regulatory compliance).
• Staining applications in biological and laboratory research.

Quality Control

Our Acid Red 414 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including color strength, shade, solubility, and impurity profile. A comprehensive Certificate of Analysis (COA) documenting purity, physical properties, and conformance to specification is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent moisture absorption and caking.
