Description

Methyl Ricinoleate is the methyl ester of ricinoleic acid, a key derivative of castor oil. This specialty ester is valued for its unique combination of a polar hydroxyl group and a non-polar hydrocarbon chain, making it a versatile intermediate and functional fluid. It is primarily sought by manufacturers in the lubricant, plasticizer, and personal care industries for its excellent solvency, low-temperature properties, and biodegradability.

Application

• Lubricant & Grease Formulation: Acts as a bio-based base oil or additive, providing good lubricity, low pour point, and enhanced solubility for thickeners and other additives.
• Plasticizer & Polymer Modifier: Used as a secondary plasticizer or co-stabilizer in PVC and other polymer systems to improve flexibility and low-temperature performance.
• Personal Care & Cosmetics: Serves as an emollient, skin-conditioning agent, and carrier oil in creams, lotions, and lipsticks due to its smooth texture and skin compatibility.
• Chemical Synthesis Intermediate: A crucial starting material for producing surfactants, estolides, and other ricinoleic acid derivatives.
• Industrial Solvent & Carrier: Employed as a solvent for dyes, resins, and inks, and as a carrier fluid in functional coatings.
• Metalworking Fluids: Functions as a friction-reducing component and corrosion inhibitor in synthetic and semi-synthetic cutting and grinding fluids.

Quality Control

Our Methyl Ricinoleate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for assay and purity, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing identity, purity, and key physical parameters is provided with every shipment to guarantee consistency and traceability for your B2B applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and oxidation.
