direct red 28 Overview

direct red 28, also known as Congo Red and C.I. Direct Red 28 (C.I. 22120), is a water-soluble azo dye widely used across the Chemical raw material and chemical product manufacturing industry and Dye manufacturing. With CAS 573-58-0 (often searched as cas 573 58 0 or simply 573-58-0), it is prized for its strong substantivity to cellulosic substrates and its bright, clean red shade. Typical commercial specifications include a high active dye content with low insolubles, excellent dissolution, and stable shade consistency, making it a dependable colorant for continuous and batch processes. Chemically, it is a diazo dye supplied as a reddish powder; it dissolves readily in warm water and provides good leveling on paper and certain fibers under appropriate electrolyte conditions.

Tangshan Moneide Trading Co., Ltd. supplies direct red 28 with rigorous batch-to-batch control, supported by COA, SDS, and technical guidance tailored to production lines. Our process-oriented approach ensures consistent hue and strength, facilitating reproducible formulations and reduced rework. Whether you are scaling a new shade standard or integrating this dye into a blended system with other directs, Moneide’s quality framework, logistics reliability, and technical support help B2B buyers de-risk supply while meeting operational KPIs in paper coloring, auxiliary formulation, and related applications.

Benefits & Use Cases of direct red 28 in Dye manufacturing

In dye manufacturing and downstream conversion, direct red 28 enables efficient coloration of paper grades (tissue, kraft, writing/printing), cellulosic fibers, and selected blends, as well as uses in laboratory indicators and biological staining. In papermaking, it offers attractive build-up and good affinity to cellulose, enabling on-machine color control and fast shade corrections. Formulators also use direct red 28 as a component in liquid dye concentrates, blending it with direct yellows and blues to achieve a broad shade gamut without compromising stability or viscosity.

• Fast dissolution and low insolubles for cleaner pipelines, fewer filter clogs, and smoother continuous dosing.
• Consistent, bright red shade for reliable shade matching and reduced trial-and-error.
• Compatibility with other direct dyes, enabling cost-optimized blends and flexible color design.

Tangshan Moneide Trading Co., Ltd. supports B2B integrators with application know-how: electrolyte optimization for exhaustion on cellulose, pH guidance for color consistency, and advice on filtration and make-down to limit undissolved particles. Our technical team’s responsiveness, combined with robust supply planning, helps manufacturers shorten qualification cycles and maintain stable production—even during peak demand.

Cost, Maintenance & User Experience

Total cost of ownership for direct red 28 hinges on dye strength, dissolution rate, and process stability. By supplying a high-purity grade with predictable strength, Tangshan Moneide Trading Co., Ltd. helps plants dose accurately and avoid overuse. Faster wet-out and dissolution reduce steam time and operator intervention, while low insolubles translate into fewer line cleanouts and better uptime. In practice, customers see smoother first-time-right results, which cuts rework and reduces off-shade waste—key drivers for ROI in large-scale dyeing or papermaking lines.

• Durability & storage: Stable in sealed bags/drums under dry, cool conditions; typical shelf life supports long planning horizons.
• Operational care: Use clean water for make-down, maintain recommended pH and electrolyte levels, and filter solutions for critical finishes.
• User feedback: Process engineers value the batch-to-batch consistency and the minimal tendency for nozzle or screen fouling in continuous systems.

Packaging is available in industry-standard sizes for safe handling and efficient warehouse management. Each shipment includes documentation (SDS/COA) and access to our technical support for quick troubleshooting and optimization—helping decision makers capture full value from every kilogram purchased.

Sustainability & Market Trends in manufacturing

Sustainability priorities in the dye sector continue to evolve around transparency, safe chemistry, and lower-impact processing. Regulatory frameworks (e.g., regional chemical inventories and brand RSLs) emphasize responsible selection of azo dyes and documentation of restricted substances. For direct red 28, buyers should evaluate end-use requirements, local regulations, and wastewater management to ensure compliant, responsible use. Process optimizations—such as higher exhaustion, improved filtration, and effective effluent treatment—reduce color load, COD, and environmental footprint.

Tangshan Moneide Trading Co., Ltd. is committed to forward-thinking, eco-conscious practices. We provide clear product data, guidance on best-practice handling, and support for customers’ ESG goals, including advice on dye-house process control and compatible treatment options (coagulation, adsorption, and advanced oxidation as appropriate). Our supply-chain planning and quality systems help partners maintain compliance, traceability, and continuity—key advantages for B2B decision makers navigating both growth and regulatory complexity in global manufacturing.
