Explore our foundational range of direct, acid, and solvent coloring agents engineered for superior industrial applications.
Oil Brown 41 (chemically classified as Solvent Brown 41 / Bismarck Brown Y Base, CAS Registry Number 1052-38-6) is a diazo organic compound widely celebrated for its robust solubility parameters in non-aqueous systems. This lipid-soluble dye displays high affinity toward organic polymer matrices, oils, and industrial solvents. At a molecular level, it functions through high dispersion capabilities, maintaining intense coloration even in highly challenging thermal environments.
China stands as the global epicentre for the manufacture of complex organic dyestuffs, specifically Solvent Brown 41. The industrial advantages provided by Tianjin-based facilities such as Tianjin Sunrise Chem Group are built upon raw material security, vertical integration of aromatic derivatives, and state-of-the-art chemical synthesizing reactors.
By utilizing automated chemical closed-loop synthesis systems, we achieve a batch-to-batch consistency that was previously unattainable. The local availability of precursor chemicals, combined with strategic deepwater port logistics in Tianjin, enables a steady supply chain that insulates global buyers from volatile price fluctuations. Furthermore, stringent environmental mandates in China have catalyzed our transition to green energy-driven production systems, making our discounted Oil Brown 41 not only highly cost-effective but also environmentally compliant.
The global chemical coloring sector is undergoing a rapid transition toward ecological accountability. Historically, solvent-based dyes faced severe scrutiny due to potential trace heavy metal contamination and free aromatic amines. Modern production shifts demand zero-discharge chemical protocols.
Tianjin Sunrise Chem Group is leading this transformation. Our operations are fully integrated with the Zero Discharge of Hazardous Chemicals (ZDHC) framework, reaching the elite ZDHC Level 3 certification. Additionally, our processes meet the criteria for the Global Organic Textile Standard (GOTS). These certifications guarantee that every shipment of Oil Brown 41 has undergone strict mass spectrometry validation to ensure it contains zero restricted substances, assisting our international buyers in passing even the most demanding retail audit procedures.
As a dedicated manufacturing pioneer, Tianjin Sunrise Chem Group bridges the gap between high-performance chemical engineering and economical supply chains.

Solvent Brown 41 is engineered for versatility. Discover how our specialized formulations serve targeted industrial needs across various sectors.
In premium wood coatings, Oil Brown 41 offers exceptional clarity, highlighting wood grain details without causing fiber swelling. Its high solubility in alcohol mixtures ensures even coverage and fast drying times, ideal for mass production of luxury furniture.
Designed to withstand temperatures exceeding 240°C during extrusion, our Oil Brown 41 is perfect for masterbatch compounding in PS, PMMA, and rigid PVC. It provides vibrant, migration-resistant coloring.
Specifically processed to avoid residue clogging, our high-purity Solvent Brown 41 dissolves quickly in packaging ink solvents. It is highly compatible with acrylic resins, yielding crisp, scratch-resistant prints.
Our focus extends beyond supplying colorants. We partner with industries to build robust, eco-conscious supply chains.
Under the management of Tianjin Sunrise Chem Group, we provide tailored formulations to meet the demands of global manufacturers. Industrial production relies on stability. A delay in raw material deliveries can disrupt production schedules, resulting in costly downtime.
By establishing long-term collaborations with textile, paper, and polymer mills, we deliver streamlined container solutions, reliable warehouse stock, and customized chemical packaging. Our certifications, including ZDHC level 3 and GOTS, ensure our products meet strict international standards, reducing environmental impact while keeping supply chains running smoothly.
A comprehensive checklist for sourcing managers to guarantee compliance and quality when purchasing Solvent Brown 41.
Always verify that insoluble residues in solvent solvents remain under 0.2%. Higher values will lead to filter clogging in printing ink applications.
Verify the dye does not release restricted aromatic amines. ZDHC Level 3 testing ensures complete elimination of hazardous chemicals.
Confirm moisture-proof barrier lining in 25kg fiber drums. Moisture absorption can lead to dye caking and reduced solubility.

A1: Solvent Brown 41 has high solubility in polar organic solvents, including ethanol, acetone, methyl ethyl ketone (MEK), and ethyl acetate. It has lower solubility in purely aliphatic hydrocarbons like hexane, which must be considered when designing solvent systems.
A2: Our premium-grade Oil Brown 41 exhibits high thermal stability, showing no significant decomposition up to 240°C. For short cycle times in extrusion and injection molding (e.g., in polystyrene or PMMA), it can withstand spikes up to 260°C without color loss.
A3: ZDHC Level 3 is the highest chemical safety certification in the textile and colorant value chain. It verifies that our formulations have been tested by a third party to ensure they do not contain priority hazardous chemicals. This prevents supply chain contamination and helps our customers meet demanding safety audits.
A4: Solvent Brown 41 is insoluble in water. For aqueous staining systems, we recommend our water-soluble direct or basic dyes. However, Solvent Brown 41 is highly effective in solvent-based, non-grain-raising (NGR) wood stains and spirit-based varnishes.
A5: Our standard packaging is 25kg multi-layer fiber drums with internal PE moisture-proof bags. For larger orders, we offer custom 500kg or 1000kg super sacks on pallets to streamline handling at your plant.
A6: Stored in its original sealed packaging in a cool, dry, and well-ventilated warehouse away from direct sunlight and oxidizing agents, Oil Brown 41 maintains its stability for up to 36 months without loss of strength.
A7: Every batch undergoes strict pre-shipment testing. Using HPLC and spectrophotometry, we check the relative color strength (98%–102% of standard), moisture levels (below 1.5%), insoluble residues in solvent (under 0.2%), and dust levels.
A8: We offer customized color matching. Our laboratory can blend Solvent Brown 41 with other solvent-soluble dyes (such as Solvent Yellow 14 or Solvent Orange 62) to create specific shades tailored to your application, ensuring consistency across production runs.
