Explore our premium grade chemical materials and solvents, manufactured under strict quality standards for global supply chains.
In the demanding realm of industrial chemical formulation, the choice of solvent has a profound impact not only on product efficacy but also on safety profile and regulatory compliance. Solvesso 200nd (where "nd" signifies "naphthalene depleted") represents a key advancement in the heavy aromatic solvent group. Categorized under CAS No. 64742-94-5, this fluid is a high-boiling aromatic hydrocarbon fraction consisting primarily of C11 to C14 alkylbenzenes.
Standard heavy aromatic solvents naturally contain up to 10% naphthalene, a volatile bicyclic aromatic hydrocarbon classified as a potential carcinogen and environmental hazard under major global GHS frameworks. Our Solvesso 200nd is refined via advanced extraction and distillation processes to reduce the naphthalene content below 1.0% (and often below 0.1%), providing formulators with an alternative that avoids restrictive hazard labeling. By minimizing naphthalene, users can satisfy strict occupational safety regulations while maintaining the solvent performance characteristics essential for complex chemical formulations.
Founded in 2004 with a registered capital of 60 million yuan, we have scaled our capacity to become a prominent supplier in the chemical park ecosystem.
Located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, Shandong Saier Chemical Technology Development Co., Ltd. has established a robust production and distribution footprint. Initially focused on local raw material refinement, we have grown into a high-capacity chemical manufacturing enterprise with an annual output capacity of 720,000 tons. Our production facilities source high-grade feedstocks directly from major global refining hubs including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical.
This integrated supply model allows us to guarantee stable supplies of crucial heavy aromatic hydrocarbons (such as Solvent Naphtha, TOPSOL, KOCOSOL, Aromatic Hydrocarbon, TOLUENE AROMATIC HYDROCARBON, NAFTA DISOLVENTE, SOLVESSO S-100, S-150, S-150ND, S-180, and S-200) alongside chemical intermediates. Our product lines serve key global chemical hubs in Asia, Europe, the Americas, and Southeast Asia, reflecting our focus on international trade compliance and reliability.
From modern agriculture to high-durability coatings, the unique physical properties of Solvesso 200nd support several key chemical systems.
Modern crop protection depends heavily on high-solvency vectors to hold active ingredients (AI) in liquid form. Solvesso 200nd acts as a carrier solvent for Emulsifiable Concentrates (EC), Emulsions in Water (EW), and Suspo-Emulsions (SE). Its high aromatic content provides the required solvency for complex pesticides, while its low naphthalene profile helps formulators avoid warning symbols on end-user packaging.
Heavy aromatic hydrocarbons are widely used in stoving enamels, coil coatings, and automotive finishes. The high boiling range (230°C–290°C) and slow, controlled evaporation rate of Solvesso 200nd allow paint films to flow and level properly before curing, minimizing surface defects like pinholes, orange peel, and blistering.
Due to its high solvency, high flash point, and thermal stability, Solvesso 200nd is utilized as a chemical intermediate and carrier solvent in oilfield operations. This includes applications in drag reducers, corrosion inhibitors, demulsifiers, and paraffin inhibitors designed for high-temperature downhole conditions.

Note on Technical Selection: The elevated flash point of Solvesso 200nd (>100°C) compared to Solvesso 100 or 150 improves workplace safety and alters shipping classifications. Under transport regulations, substances with a flashpoint above 100°C face fewer logistics restrictions, lowering shipping costs and easing warehousing compliance.
Regulatory frameworks such as ECHA's REACH and the US EPA's Clean Air Act continue to place tighter restrictions on VOC emissions. As a result, industrial solvent development is moving toward heavier, lower-volatility molecular structures.
Shandong Saier Chemical's research roadmap focuses on two primary areas:
By upgrading our production infrastructure, we aim to ensure our global clients have access to compliant, high-purity solvents that satisfy both local and international safety guidelines.
Our operations prioritize safety, consistency, and technological efficiency across all stages of refining and logistics.
Industrial procurement requires more than competitive pricing; it demands supply chain security, regulatory support, and consistent quality.
We source raw materials through long-term contracts with state-backed energy groups including Sinopec and PetroChina. This baseline helps insulate our output and pricing from localized market fluctuations, ensuring consistent product availability for our contractual buyers.
Every production run undergoes gas chromatography (GC) and mass spectrometry (MS) testing to verify chemical composition, distillation endpoints, flash points, and naphthalene levels. We provide batch-specific COAs to document compliance with requested parameters.
We support multiple shipping modes including ISO tank containers, chemical vessel bulk deliveries, and standard 200L steel drums. Our location in Zibo City, Shandong, provides access to the rail and highway networks serving Qingdao Port, facilitating efficient international export.
Get professional answers to common technical, regulatory, and procurement questions regarding Solvesso 200nd and heavy aromatic solvents.
"ND" stands for "Naphthalene Depleted". Standard Solvesso 200 contains between 4% to 9% naphthalene by weight. Under global hazard classification codes (GHS and EU CLP), naphthalene is classified as a Class 2 carcinogen and is toxic to aquatic life. Solvesso 200nd has its naphthalene content reduced below 0.9% (typically below 0.1%), which allows it to avoid the hazardous health labels required for standard aromatics in many jurisdictions.
The main difference lies in the boiling range and carbon distribution. Solvesso 150nd consists primarily of C9-C11 hydrocarbons with a boiling range of 180°C–210°C. Solvesso 200nd is composed of C11-C14 hydrocarbons, yielding a higher boiling range of 230°C–290°C and a higher flash point (>100°C compared to >63°C for S150nd). Solvesso 200nd evaporates more slowly, making it suitable for applications requiring high-temperature processing or long open times.
It is commonly used in Emulsifiable Concentrates (EC) and Suspo-Emulsions (SE) containing complex active ingredients (AIs) like pyrethroids, triazoles, and organophosphates. Its high solvency power keeps the AI dissolved during cold storage, while its high flash point improves safety during transport and mixing operations.
Yes. Our refinery in the Qilu Chemical Industrial Park operates fractional distillation columns with process control software. This allows us to adjust distillation curves, flashpoints, and aromatic density profiles to meet specific customer requirements, providing customized OEM formulations alongside our standard solvent ranges.
While Solvesso 200nd has a high flashpoint (>100°C) and is not classified as a flammable liquid under GHS (which generally covers flashpoints <60°C), it remains combustible. It should be stored in cool, well-ventilated warehouses away from strong oxidizing agents and ignition sources. Grounding systems should be used during liquid transfer to prevent static discharge, and double-walled steel tanks or bunded storage areas are recommended for spill containment.
Shandong Saier Chemical operates under an ISO 9001 quality management system and an ISO 14001 environmental management framework. We supply full GHS-compliant Safety Data Sheets (SDS) and certificates of analysis (COA) for every batch. We also coordinate with importers in Europe, the Americas, and Asia to assist with local registration requirements.
