Understanding the chemical properties, molecular performance criteria, and strict industrial specifications.
Basic Red 1, commonly recognized within the Color Index as C.I. Basic Red 1 (45160) or commercially as Rhodamine 6GDN, is a synthetic cationic dye belonging to the xanthene chemical family. Characterized by its exceptional bright pink to reddish-violet fluorescent hue, it offers outstanding tinctorial strength and excellent affinity towards negatively charged substrates like acrylic fibers, paper pulp, and tannin-mordanted cotton.
As a prime manufacturer based in China, Tianjin Sunrise Chem Group ensures optimized purification processes to yield low-insoluble and highly soluble powder or liquid formats to fit the demands of specialized industrial printers, trace detection equipment, and advanced textile processing systems.

Ensuring cross-border reliability, secure maritime logistics, and seamless local compliance integrations.
Cooperating with global textile and paper mills for decades highlights our factory's role as a vital link in the international industrial chemical supply chain. Long-term commercial collaborations demand more than competitive pricing; they require a commitment to logistics agility, steady volume outputs, and responsive technical services.
Our dedicated team coordinates closely with port authorities and customs to dispatch containers under strict safety procedures. Whether shipping custom dry powders or dust-free liquid concentrates, we ensure compliance with international hazardous goods regulations (ADR/IMDG). Through a network of regional partners, we also provide localized technical support and customer clearance assistance to mitigate disruptions.
Strategic Warehousing: We maintain strategic inventories of core basic and liquid dyes to satisfy urgent spikes in demand, preventing shut-downs in fast-moving paper mill runs and high-volume apparel manufacturing plants.

Reducing hazardous discharges and driving organic certification pathways across textile operations.
Environmental preservation represents the cornerstone of modern chemical manufacturing. To ensure our clients meet their local environmental laws, we focus heavily on aligning with chemical restriction lists (MRSL). The ZDHC program (Zero Discharge of Hazardous Chemicals) is a collaborative initiative aimed at reducing toxic substances throughout value chains. Our ZDHC Level 3 status indicates that our inputs and processing methods satisfy strict international chemical handling benchmarks.
Simultaneously, our compliance with the Global Organic Textile Standard (GOTS) ensures that organic-labeled materials remain pure from harvesting through production. This twin-track strategy provides a solid foundation for companies targeting sustainable markets worldwide.
How we address complex coloring needs across diverse industrial applications using advanced methodologies.
Basic Red 1 features a highly optimized exhaustion rate on acrylic fibers, minimizing wash-off. This reduces wastewater treatments and enhances overall batch efficiency.
Our specialized granular and liquid formulations prevent chemical dusting in production zones, keeping working environments cleaner and safer for plant operators.
Through advanced molecular dispersion, our dyes produce rich, bright pinks at lower concentrations, cutting formulation requirements and transportation weights.
The global industrial dyes market is shifting rapidly toward lower energy consumption, minimal water waste, and bio-based raw materials. Tianjin Sunrise Chem Group is leading this evolution by updating our synthesis pathways to run at lower reaction temperatures, significantly reducing the carbon footprint of our operations.
By designing dyes that excel under lower temperatures, we help textile finishing plants conserve electricity and steam during processing. Our forward-looking development strategy also targets hybrid liquid solutions that interface seamlessly with digital dosing software, reducing human error and chemical waste.
In addition to process refinements, our research center continues to source bio-derived solvents to gradually replace petroleum-based carrier agents in our liquid ranges. This ongoing transformation ensures our partners can confidently meet carbon border adjustment mechanisms (CBAM) and other emerging international environmental policies.

We operate on the principle that our customers' business success is directly tied to our own performance as a partner. Because of this, we build relationships focused on transparent communication, consistent quality, and responsive support.
Beyond supplying raw dyes, we work closely with clients to address issues related to shade matching, formulation adjustments, and regulatory compliance. Our technical support specialists are always available to help troubleshoot application difficulties, review environmental documentation, or coordinate custom product runs.
By choosing Tianjin Sunrise Chem Group, you gain a partner dedicated to supporting your operational stability. We ensure clear tracking on all shipments, provide comprehensive quality control certificates, and remain flexible to accommodate changing production schedules. Let's work together to drive efficiency and progress in your coloration processes.
Addressing crucial chemical property questions, handling safety measures, and global supply logistics concerns.
Basic Red 1 (CAS 989-38-8) belongs to the xanthene chemical group and is commonly processed as a bright red powder or liquid. It provides intense tinting strength and distinct fluorescence under UV lighting, making it a primary choice for high-visibility inks, fluorescent coloring systems, and specialty papers.
ZDHC Level 3 is one of the highest levels of chemical compliance in the textile supply chain. It indicates that the manufacturing facility has undergone thorough third-party review of chemical formulations and raw inputs to ensure no restricted substances (MRSL) are released into processing lines, helping buyers avoid regulatory delays and maintain their own eco-friendly standards.
Stored in its original, sealed drums in dry, cool, and well-ventilated areas, Basic Red 1 dry powder has a typical shelf life of 36 months. Keeping it away from direct sunlight, high heat, and moisture prevents clumping and maintains the product's solubility.
Yes, we offer multiple packaging options, including 25kg iron drums, carton boxes, woven bags, and custom super sacks. We also prepare specialized pallet sizing with protective shrink wrapping to prevent damage during shipping and make warehouse storage straightforward.
