Isooctyl Alcohol

Isooctol (2-ethylhexanol) is an important C8 branched alcohol and a core raw material in the plasticizer industry. Renowned for its excellent reactivity, low volatility, good solubility, and chemical stability, it is widely used in the production of plasticizers (DOP, DOTP, DOA, DOS, TOTM, etc.), solvents, additives, surfactants, and lubricant additives. It is an irreplaceable key raw material in the PVC plastic products industry.

Product Description

In the plasticizer field, DOP, produced by the reaction of isooctol with phthalic anhydride, is the most important and widely used plasticizer in PVC flexible products, giving PVC products excellent softness, extensibility, and processing performance. DOTP, produced by the reaction with terephthalic acid, is an environmentally friendly plasticizer that complies with EU REACH and other environmental regulations, and is an important substitute for DOP. Products are available in multiple grades, including plasticizer grade, industrial grade (solvent/additive grade), high-purity/electronic grade, and specialty grade, to meet the diverse needs of customers in different industries. Our products strictly adhere to national standards such as GB/T 6818-2020, support small-batch trial orders and customized packaging, and rely on major ports such as Qingdao Port, Tianjin Port, and Shanghai Port for efficient and worry-free export throughout the entire process.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
