Explore our primary chemical colorants engineered for consistent performance across textile, paper, wood coating, and plastic industrial processing.
Providing key engineering insights, chemical profiles, and information gains on Solvent Yellow 14 (CI 12055) for purchasing managers.
Sudan Yellow 14, chemically indexed as Solvent Yellow 14 (C.I. 12055), is a synthetic fat-soluble azo dye utilized extensively across a wide array of organic polymer materials, paraffin waxes, lubricants, shoe polishes, and industrial pyrotechnics. Structurally characterized as 1-(phenylazo)-2-naphthol, this monoazo compound displays exceptional solubility properties in organic solvents, oils, fats, and liquid hydrocarbons, manifesting as a brilliant yellow-to-orange shade with remarkable thermal stability.
In the contemporary industrial colorants market, the sourcing of high-purity Sudan Yellow 14 has shifted toward specialized manufacturing facilities capable of delivering customized technical specs. As an OEM provider, Tianjin Sunrise Chem Group provides bespoke physical form optimizations, particle size distribution modifications, and strictly controlled purity metrics to satisfy stringent global regulatory frameworks.
Global demand is propelled by the rising consumption of high-grade automotive lubricants, engineering plastics requiring precise coloration markers, and thermal transfer processing aids. By working with a verified manufacturer possessing robust vertical integration, procurement entities bypass volatile distribution pricing and secure consistent batch-to-batch chemical properties.

How regional climatic variations and specific industrial requirements influence the synthesis and modification of Solvent Yellow 14.
In temperate and tropical zones, wax crystallization velocities vary greatly. Our specialized OEM Sudan Yellow 14 undergoes custom crystallization retardation to prevent dye precipitation or blooming in candles, industrial waxes, and protective polishes even under fluctuating warehouse temperatures.
Utilized as a high-visibility marker dye for hydraulic fluids, transmission oils, and petroleum products. The formulation is optimized to ensure maximum miscibility without altering the viscosity index or oxidation stability margins of the base petroleum product.
Engineered to survive thermal processing windows in extrusion machinery up to 220°C. OEM adjustments in molecular dispersion dynamics ensure that polymer granules maintain structural color consistency without thermal degradation or off-gassing.

How Tianjin Sunrise Chem Group achieves structural cost benefits and continuous operations.
A primary failure point in solvent dye sourcing is the volatility of precursor chemicals (such as aniline and 2-naphthol). Our Tianjin facility maintains raw material hedging agreements and direct pipeline integrations with petrochemical complexes, insulating clients from sudden market spikes and guaranteeing uninterrupted manufacturing cycles.
By using closed-loop recycling mechanisms for organic process solvents, we reduce both chemical waste discharge and structural production costs. This approach keeps our pricing competitive while meeting ZDHC Level 3 environmental standards.
Delivering high-purity chemical colorants across international borders with confidence.
With years of experience, we have successfully established strong partnerships in many countries. Our dedication to meeting global demands and exceeding customer expectations has earned us a reputation as a reliable supplier worldwide.

Important safety guidelines, global transport protocols, and correct industrial handling parameters for Solvent Yellow 14.
Sudan Yellow 14 (CI 12055) is designed exclusively for industrial formulations (e.g., lubricants, waxes, plastics). Under international regulations (EU, FDA), it is strictly prohibited from use in food dyes, cosmetics, or topical applications. We require our customers to verify industrial compliance before purchase.
Appropriate personal protective equipment (PPE)—including nitrile gloves, protective eyewear, and dust respirators—must be worn during handling. Avoid dust generation. Store in a cool, dry, well-ventilated warehouse space isolated from strong oxidizing agents.
Our OEM dye formulations comply with regional environmental and chemical control lists, including EU-REACH, China-IECSC, US-TSCA, and RoHS requirements. Fully documented Certificates of Analysis (CoA) accompany every container dispatch.
Answering complex chemical, engineering, and logistics questions from professional colorant buyers.
While both are azo-based solvent dyes, Solvent Yellow 14 (CI 12055) is a monoazo dye providing a red-leaning yellow shade, whereas Solvent Yellow 56 (CI 11021) is a dialkylaminoazo dye with a greener-yellow profile. Solvent Yellow 14 exhibits higher thermal tolerance in high-melting-point waxes and specific plastic molding compounds, making it a preferred choice for automotive polishes and pyrotechnic smoke formulations.
No, Sudan Yellow 14 (often associated with Sudan I) is classified under class 3 carcinogens by IARC and is prohibited from food contact applications in major markets. Our factory supplies this dye strictly for industrial non-food coloration (e.g. industrial lubricants, markers, automotive finishes, candle wax). We advise all OEM clients to maintain rigorous isolation systems to prevent cross-contamination.
Our OEM services cover three primary areas: physical state modification (from standard 80-mesh powder to low-dust micro-granules or pre-dispersed liquid systems), chemical formulation optimization (varying purity and salt content based on application requirements), and tailored packaging (ranging from 25kg fiber drums to 500kg super sacks designed for automated dosing units).
We utilize automated spectrophotometric evaluation systems (CIELAB system) to test every production run against standard control samples. If any shade deviation (dE > 0.5) is detected, the batch is refined. We also run HPLC testing on all shipments to verify purity percentages and control chemical residues before export clearance.
When stored in dry, unopened containers below 30°C and away from sunlight, Sudan Yellow 14 retains its performance parameters for up to 60 months. Proper closure of liners after opening is required to prevent moisture absorption.
Our chemical facilities operate under ISO 9001 and ISO 14001 guidelines. Key product ranges conform to the ZDHC Level 3 chemical management registry and carry GOTS certification, demonstrating our commitment to sustainability and green chemistry practices.
