High-purity chemical dyes engineered for polymers, textiles, paper, and demanding technical applications.
An authoritative technical brief on chemical configurations, regulatory boundaries, and international supply-chain optimization for solvent-based coloring compounds.
In the global industrial colorant market, Oil Orange 3g—predominantly cataloged under the Color Index as Solvent Orange 7 (and chemically related to structural variants such as Sudan II)—represents a crucial monoazo dye. Known for its exceptional solubility in organic solvents, hydrocarbons, oils, fats, and waxes, this dye is heavily utilized where water-soluble colorants fail to perform. Its chemical structure features an azo group linked to naphthalene derivatives, offering brilliant orange shades characterized by superior tinting strength.
As a leading China Oil Orange 3g manufacturer, Tianjin Sunrise Chem Group ensures that our synthetic pathways are tightly regulated. We address a critical concern of modern procurement agents: the presence of free Primary Aromatic Amines (PAAs). By employing precise diazotization and coupling temperatures and optimized recrystallization steps, our manufacturing process reduces impurities to levels well below the limits mandated by European and American environmental authorities.
Tianjin Sunrise Chem Group specializes in manufacturing high-quality dyestuffs. Including Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes and Fluorescent dyes. Backed by decades of industry and export experience, we have built a reputation for reliability and excellence, serving clients from diverse sectors including denim, textile, leather, paper and plastic.
We always highly focus on the goods quality and stability. Each shipment has been tested before sending to the port. ZDHC level 3 and GOTS certificate makes your quality guaranteed. We pride ourselves on offering customized solutions. Our team of experts works closely with clients to understand their unique needs and delivers tailored products and services. We actively seek strategic partnerships to expand our reach and enhance our offerings. Collaborate with us to explore mutual growth opportunities.

The global procurement landscape for Oil Orange 3g has shifted significantly due to stricter environmental regulations, fluctuating petrochemical costs, and a demand for supply chain transparency. Modern procurement managers are no longer focusing solely on low price points; instead, they are prioritizing compliance markers like REACH, RoHS, and heavy-metal limits.
Furthermore, the global energy transition has driven demand for markers in fuels and lubricants. Oil Orange 3g is highly sought after as a chemical marker for petroleum products, providing instant visual identification of fuel grades, tax statuses, and brand authenticity. Ensuring batch-to-batch solubility in base oils and maintaining zero moisture content are critical technical requirements for international shipping.

The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to reduce the use of hazardous chemicals. The focus of this certification is on eliminating the release of hazardous chemicals into the environment throughout the entire supply chain. Achieving ZDHC certification indicates that our company has implemented robust chemical management procedures and has met the stringent requirements for chemical handling, wastewater treatment, and pollution prevention.
The Global Organic Textile Standard (GOTS) is a certification that ensures the organic status of textiles from the harvesting of raw materials to environmentally and socially responsible manufacturing. The GOTS certification guarantees that the textiles are made from organic fibers, that chemical inputs are minimized, and that strict environmental and labor standards are met throughout the production process. GOTS certified products are considered to be sustainable, safe, and ethical.
We firmly believe in building relationships with our clients based on trust and mutual benefit. We know that our customers' success is our success, so we are committed to providing quality services to meet their needs.

Looking forward, the research division of Tianjin Sunrise Chem Group is targeting green synthesis methods. We are actively investigating bio-derived solvents as substitute carrier liquids for liquid dye variants and implementing clean-coupling technologies to eliminate toxic by-products at the molecular level.
Our technological roadmap aims to enhance the color concentration of our liquid dye formulations by an additional 15% over the next two years. This improvement will allow global distributors and manufacturing plants to optimize storage space and reduce ocean shipping carbon footprints. Through these innovations, we continue to bridge the gap between high-performance color output and environmental responsibility.
