What is Hydrogenated Castor Oil (Castor Wax)?
Hydrogenated Castor Oil (HCO), known industrially as castor wax, is a hard, brittle vegetable wax produced by the controlled chemical saturation of pure refined castor oil. The natural triglyceride structure of castor oil contains ricinoleic acid, which features an unsaturated double bond between carbons 9 and 10 as well as a secondary hydroxyl group at carbon 12. During the catalytic hydrogenation process, hydrogen gas reacts across the double bonds in the presence of a specialized nickel catalyst, completely saturating the carbon chains to form 12-hydroxystearic acid triglycerides.
This chemical transformation dramatically elevates the melting point from a room-temperature liquid into a crystalline solid wax exhibiting a sharp dropping point between 85°C and 88°C. Crucially, catalytic hydrogenation preserves the secondary hydroxyl group on each fatty acid chain. This unique combination of high melting temperature, insolubility in water, and hydroxyl polarity makes HCO an pronounced functional additive in industrial grease compounding, powder coatings, hot-melt adhesives, and polyurethane formulations. Procurement managers seek hydrogenated castor oil bulk supply Gujarat to ensure consistent dropping point performance, low residual iodine value, and stable batch supply.

How Nagdev Produces Hydrogenated Castor Oil in Deodar
Nagdev Products manufactures Hydrogenated Castor Oil at our manufacturing facility located at Survey No. 301 P-2, Jada-Kotarwada Road, Village Sardarpura, Taluka Deodar, District Vav-Tharad, Gujarat 385330. Operating an integrated processing setup with a 50 TPD seed crushing capacity, our production chain executes catalytic hydrogenation under accurate process automation:
- Feedstock Refining: Freshly expelled First Special Grade (FSG) castor oil is pre-treated and dried to eliminate trace moisture and impurities that could deactivate hydrogenation catalysts.
- Catalytic Hydrogenation Reaction: The dry refined oil is charged into high-pressure stainless steel hydrogenation autoclaves. high-grade hydrogen gas is sparged through the oil in the presence of an active nickel catalyst under controlled pressure and temperature (140°C–180°C). The reaction continues until the iodine value drops below 5.0 g I2/100g, indicating complete double bond saturation.
- Catalyst Filtration: The molten hydrogenated wax is pumped through closed pressure leaf filters to separate and recover the nickel catalyst particles completely, yielding an optically clear, transparent molten wax.
- Continuous Flaking and Solidification: The molten wax feeds onto internal water-cooled rotating flaker drums. As the wax contacts the chilled drum surface, it solidifies into uniform, free-flowing white crystalline flakes.
- Screening and Packaging: The solid flakes are classified, metal-detected, and packed into 25 kg moisture-barrier poly-lined paper bags, followed by automated palletization.

Technical Specifications & Plain Parameter Explanations
Industrial buyers evaluate Hydrogenated Castor Oil against strict analytical limits documented on the Certificate of Analysis:
- Dropping Point (Mettler / Ubbelohde): Specified between 85.0°C and 88.0°C. The dropping point is the defining physical metric for castor wax. A high, sharp melting point confirms complete molecular saturation and ensures high thermal stability when used as a thickener in automotive greases.
- Iodine Value: Maintained below 5.0 g I2/100g. Residual iodine value measures remaining unhydrogenated double bonds. Low iodine value ensures complete resistance to oxidation, yellowing, and thermal rancidity.
- Acid Value: Controlled below 3.0 mg KOH/g. Low acid value ensures minimal unreacted free fatty acids, preventing corrosion on metallic parts and avoiding interference with polyurethane catalysts.
- Saponification Value: Specified between 175 and 185 mg KOH/g, confirming high ester purity and guiding stoichiometric calculations for specialty soap or ester conversions.
- Hydroxyl Value: Specified between 155 and 165 mg KOH/g. The retention of secondary hydroxyl functionality provides the basis for rheological hydrogen bonding in thixotropic coatings.
- Physical Appearance: Clean, free-flowing white to off-white flakes or powder, free from foreign particulate contamination.

Primary Industrial Applications of Castor Wax
The functional properties of Hydrogenated Castor Oil support heavy-duty industrial formulations:
1. High-Temperature Lithium and Lithium-Complex Greases
HCO is the primary organic raw material used to produce lithium grease thickeners derived from castor wax (12-hydroxystearic acid is under development). During grease cooking, the ester bonds of HCO are reacted with lithium hydroxide in base oils to form micro-fibrous soap matrices. These greases exhibit pronounced mechanical shear stability, high dropping points (>190°C), and water-washout resistance in automotive wheel bearings and heavy machinery.
2. Thixotropic Agents in Paints, Sealants, and Inks
When dispersed under controlled shear and temperature in solvent-borne paints, epoxy coatings, and mastic sealants, HCO forms a reversible hydrogen-bonded network. This thixotropic behavior prevents pigment settling during storage and prevents paint sagging on vertical surfaces during application.
3. Hot-Melt Adhesives and Wax Formulations
In packaging hot-melts and bookbinding adhesives, HCO acts as a bio-based open-time modifier and viscosity reducer. It increases crystallization speed, improves bond strength at elevated temperatures, and provides moisture barrier resistance.
4. Plastics, PVC Lubricants, and Rubber Compounding
In rigid PVC extrusion and technical rubber compounding, castor wax functions as an internal-external lubricant. It improves melt flow through extrusion dies, prevents surface sticking, and enhances gloss without impairing structural impact resistance.
