Premium Industrial Castor Oil | 100% Bio-based Chemical Feedstock | CAS 8001-79-4
Overview
Castor Oil is a pale yellow, viscous, and non-volatile vegetable oil extracted from the seeds of the Ricinus communis plant. What chemically distinguishes Castor Oil from all other commercial seed oils is its extraordinarily high concentration (up to 90%) of Ricinoleic Acid—an 18-carbon fatty acid featuring a unique hydroxyl group. This specific molecular structure imparts exceptional viscosity, high-temperature lubrication, and unparalleled chemical reactivity.

Premium Industrial Castor Oil | Bio-based Feedstock
Product Overview
Castor Oil is a pale yellow, viscous vegetable oil. What chemically distinguishes Castor Oil from all other commercial seed oils is its extraordinarily high concentration (up to 90%) of Ricinoleic Acid—featuring a unique hydroxyl group. This specific molecular structure imparts exceptional viscosity, high-temperature lubrication, and unparalleled chemical reactivity.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply Premium Industrial Grade Castor Oil tailored for advanced chemical synthesis. As the world rapidly shifts away from petrochemicals, our 100% renewable, bio-based Castor Oil serves as the ultimate ESG-compliant building block for global manufacturers of polyurethanes, synthetic lubricants, and performance resins.
Technical Specifications (COA)
We maintain strict quality control to ensure optimal reactivity for downstream polymerization. Typical specifications for our Industrial Grade No. 1:
| Hydroxyl Value | 160 - 168 mg KOH/g |
|---|---|
| Acid Value | ≤ 2.0 mg KOH/g |
| Moisture & Volatile Matter | ≤ 0.2% |
| Iodine Value | 82 - 90 g I2/100g |
| Color (Gardner) | ≤ 2 |
Key Applications
- Bio-based Polyurethanes (PU): The natural hydroxyl groups make it a perfect bio-polyol. It reacts directly with isocyanates to produce high-performance, moisture-resistant PU foams, adhesives, and floor coatings.
- Chemical Feedstocks: The foundational raw material for synthesizing Sebacic Acid, 12-HSA, and Undecylenic Acid.
- Industrial Lubricants: Its extremely stable viscosity and polar affinity to metal surfaces make it an excellent base fluid for aviation and metalworking lubricants.
- Cosmetics: Used as a highly stable emollient and moisturizing agent in premium personal care formulations.
🌍 Replace Petroleum Polyols with Green Chemistry
For Polyurethane (PU) manufacturers, Castor Oil is a direct, drop-in replacement for traditional petroleum-derived polyether polyols. Formulating with our Castor Oil not only drastically increases the renewable carbon index of your coatings and foams to meet stringent ESG mandates, but it also imparts superior water resistance and flexibility to the final polyurethane matrix.
Bulk Liquid Packaging Options
As a stable, non-hazardous liquid, we offer highly cost-effective bulk packaging for global ocean freight:
- 21 MT Flexitanks (Most cost-effective for massive bulk procurement).
- 1000 KG IBC Totes (Recommended for direct job-site pumping).

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
