Understanding the Chemistry, Regulatory Landscapes, and Market Demands for C10 Aromatic Hydrocarbons
Garasol 150 (commonly referred to as Aromatic Solvent 150 or Solvesso 150) is a complex mixture of heavy aromatic hydrocarbons obtained from the distillation of aromatic streams derived from petroleum. Predominantly composed of C9 to C11 alkylbenzenes (specifically C10 isomers), it features a boiling range of approximately 180°C to 210°C. Characterized by high solubility parameters, a high flash point (>62°C), and uniform evaporation rates, this heavy aromatic hydrocarbon solvent serves as a cornerstone in high-value chemical processing.
As environmental regulations tighten globally, the demand for high-purity variants—especially naphthalene-depleted (ND) grades—has surged. Traditional Garasol 150 contains up to 10% naphthalene, a compound subject to strict environmental and health screening. Premium manufacturers in China, including Shandong Saier Chemical Technology Development Co., Ltd., have invested in multi-stage fractionation and crystallization technologies to produce low-naphthalene alternatives like S-150ND (naphthalene content <1%, and in custom grades <0.1%), addressing compliance needs for EU REACH and EPA registrations.
Understanding the precise structural mechanics of C10 aromatics is key to optimizing formulation stability in crop protection products, high-bake industrial coatings, and oilfield applications.

Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. is a specialized chemical manufacturer headquartered at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, China. Saier Chemical operates state-of-the-art hydrocarbon distillation columns and refining networks, producing a broad portfolio of environmental solvents and high-boiling aromatics.
With an initial registered capital of 60 million yuan, our enterprise established strategic partnerships with tier-one refining institutions, sourcing premium raw C10 and C12 petroleum streams from Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. By integrating industrial supply chains, Saier has achieved an annual output capacity of 720,000 tons of aromatic hydrocarbon solvents and fine chemical intermediates.
Our core products include Aromatic Solvent S100, S150 (Garasol 150 equivalent), S150ND, S180, S200, PVC plasticizers, Thiophene, 1,3-Cyclohexanedione, Heat Transfer Oils L-QC320, and Durene. Certified as a National High-Tech Enterprise, our production lines utilize automated DCS controls and online gas chromatography systems, ensuring chemical consistency across bulk, flexibag, and ISO tank shipments to markets in Asia, Europe, North America, and South America.
How Garasol 150 powers key industries worldwide with high solvency and environmental performance
In crop protection, Garasol 150 functions as a carrier solvent for active pesticide ingredients in Emulsifiable Concentrates (EC) and Oil Dispersions (OD). Its low water solubility and high flash point prevent crystallization, ensuring emulsion stability under diverse thermal conditions.
Automotive, coil, and maintenance coatings rely on S-150 for its slow evaporation rates, which improve paint flow, leveling, and gloss. Its high boiling range makes it suitable for high-bake architectural finishes and industrial printing inks.
Garasol 150 acts as a dissolution medium for drag reducers, corrosion inhibitors, and paraffin dispersants in oil exploration. It assists in maintaining viscosity balance in deep-well extraction systems under high-temperature environments.
Regulatory updates from the European Chemicals Agency (ECHA) and the US Environmental Protection Agency (EPA) have placed naphthalene under carcinogenicity assessments. Formulators must adapt to maintain product registrations without losing the solvent capabilities of C10 aromatics.
Shandong Saier Chemical's S-150ND addresses this challenge. Our low-naphthalene heavy aromatic solvent offers the solvency of standard Garasol 150, but with a naphthalene content reduced below 0.9 wt%. This modification satisfies environmental, health, and safety (EHS) requirements.
Integrating chemical supply chain logistics and manufacturing expertise from China's chemical hubs
Located in the Qilu Chemical Industrial Park in Zibo City, Shandong, we operate near major crude refineries, securing a stable and continuous raw material supply chain.
We supply aromatic solvents (S100 to S200), specialty monomers (Thiophene, 1,3-Cyclohexanedione), and plasticizers, streamlining procurement for buyers.
Our labs test raw materials and finished products using gas chromatography, flashpoint analyzers, and Karl Fischer moisture titrators to meet international standards.
Near Zibo's transport networks, we offer bulk vessel shipments, ISO tank container fleets, and flexible road tanker deliveries to Qingdao Port for global export.
We provide full safety data sheets (SDS) compliant with GHS, ISO certifications, and regulatory support for overseas import licensing.
