Commercial Castor Oil Supplier in Gujarat: Specs & Supply

What is Commercial Castor Oil?

Commercial castor oil is the raw, unrefined vegetable oil obtained through the primary mechanical pressing of Ricinus communis seeds. Known across industrial manufacturing as industrial castor oil or crude expeller castor oil, this grade preserves the natural chemical profile of the castor bean. The predominant component of commercial castor oil is ricinoleic acid (12-hydroxy-cis-9-octadecenoic acid), which comprises 85% to 90% of the total triglyceride fatty acid structure.

The distinct molecular feature of ricinoleic acid is its secondary hydroxyl group situated at the 12th carbon atom. This functional group, combined with a cis double bond between carbons 9 and 10 and a carboxyl group at carbon 1, endows the oil with natural polarity, high kinematic viscosity, and wide-ranging chemical reactivity. Chemical formulators rely on this structure to execute esterification, sulfonation, and polyurethane polymerization without requiring synthetic functionalization. Working directly with an operational commercial castor oil supplier in Gujarat ensures authentic mechanical extraction, consistent lot parameters, and reliable material traceability.

How Nagdev Produces Commercial Castor Oil in Deodar

Nagdev Products manufactures commercial grade castor oil at our production complex situated at Survey No. 301 P-2, Jada-Kotarwada Road, Village Sardarpura, Taluka Deodar, District Vav-Tharad, Gujarat 385330. Our plant operates with a dedicated 50 TPD seed crushing capacity based strictly on mechanical screw expelling technology:

1. Seed Reception and Pre-Cleaning: Castor seeds harvested across the North Gujarat agricultural belt arrive at our intake yard. The seeds pass through vibratory screen cleaners, air aspirators, and high-intensity magnetic grids to eliminate chaff, soil particles, plant stalks, and metallic debris.
2. Conditioning and Expeller Pressing: Cleaned seeds feed into heavy-duty mechanical screw expellers. The expeller barrel uses continuous rotational pressure to compress the seed mass, rupturing oil cells and expelling the raw triglyceride fluid through drainage cage bars. This process is entirely mechanical; no hexane or chemical solvent is used at our facility.
3. Gravity Settling of Foots: The crude expelled oil contains coarse meal solids (foots). It flows into primary settling troughs where heavy particulate matter separates under natural gravity settling.
4. Plate-and-Frame Clarification: Settled oil is pumped through recessed plate-and-frame filter presses fitted with woven cotton and synthetic filter fabrics. This step removes fine suspended solids, delivering clarified, clear amber unrefined commercial castor oil.
5. Quality Verification and Tank Storage: Each production run transfers to dedicated clean steel storage tanks where in-house QC technicians draw representative samples for lot release analysis.

Commercial Castor Oil Supplier in Gujarat: Sourcing & Operations

Partnering with an established commercial castor oil supplier in Gujarat offers distinct operational advantages. As a direct commercial castor oil supplier in Gujarat, we maintain reliable bulk inventories ready for rapid factory dispatch.

Gujarat produces over three-quarters of India's annual castor harvest, driven by fertile semi-arid soil and established agricultural marketing infrastructure across North Gujarat's castor belt (Banaskantha and Vav-Tharad region). Sourcing seeds directly from regional farmers and APMC mandis across Tharad, Deesa, and Palanpur allows our facility to procure freshly harvested seed with optimal oil quality and minimal hydrolytic deterioration.

From our Deodar crushing plant, road logistics provide rapid connectivity across domestic industrial corridors and seaport departure gates:

• Western India Industrial Corridors: Seamless transit direct road transit connects our facility to major manufacturing clusters in Ahmedabad, Vadodara, Dahej, Ankleshwar, and Vapi.
• Northern Industrial Markets: Reliable freight lines supply manufacturing facilities in Rajasthan, Haryana, Delhi NCR, and Punjab.
• Port Logistics for Export Enquiries: Export enquiries welcome. Our plant is equipped with road access to Kandla (Deendayal Port) and Mundra Port, allowing liquid flexitanks and containerized drums to arrive at dockside container freight stations efficiently.

Technical Specifications & Plain Parameter Explanations

Industrial buyers evaluate commercial castor oil against established standard parameters. Understanding these parameters ensures correct selection for technical applications:

• Free Fatty Acids (FFA): Specified at 2.0% maximum (calculated as oleic acid). Free fatty acids indicate the degree of hydrolytic breakdown in the seed before and during extraction. Keeping FFA below 2.0% is vital for downstream alkyd synthesis and lubricant stability.
• Moisture and Volatile Matter: Specified at 0.5% maximum. Residual moisture can cause haze, accelerate storage degradation, and cause uncontrolled foaming during high-temperature esterification or polyurethane urethane reactions.
• Colour (Lovibond Scale): Measured in a 1-inch cell, specified at 40 units maximum (Yellow + 5xRed). The natural golden-amber coloration is standard for unbleached technical oil.
• Hydroxyl Value: Specified between 160 and 168 mg KOH/g. This represents the concentration of free reactive secondary hydroxyl groups, serving as the critical benchmark for isocyanate stoichiometry in polyurethane compounding.
• Iodine Value: Typically ranges from 82 to 90 g I2/100g, verifying the presence of a single unsaturated double bond per ricinoleic chain and confirming resistance to atmospheric oxidative rancidity.
• soap formation Value: Ranging between 176 and 187 mg KOH/g, providing the basis for alkali consumption in specialty soap making, sulfonation, and fatty acid cleavage reactions.

Primary Industrial Applications

The natural fatty acid profile of commercial castor oil supports diverse chemical manufacturing sectors:

1. Industrial Lubricants and Heavy-Duty Greases

Due to its secondary hydroxyl group, commercial castor oil exhibits high surface affinity for metal substrates. It provides boundary lubrication films with enhanced load-carrying capacity and high shear stability in two-stroke motor oils, industrial gear lubricants, and wire rope greases.

2. Alkyd Resins and Industrial Coatings

In architectural coatings and maintenance enamels, commercial castor oil acts as a non-drying, plasticizing fatty component. Its hydroxyl functionality reacts into the polymer backbone, providing elasticity, adhesion to metal, and resistance to chemical corrosion.

3. Turkey Red Oil (Sulfonated Castor Oil)

Commercial grade oil is the industry-standard raw material for manufacturing sulfonated castor oil (Turkey Red Oil). Reacting unrefined oil with concentrated sulfuric acid creates an anionic surfactant that disperses freely in water, widely used in textile dyeing, leather tanning, and agrochemical formulations.

4. Bio-Based Polyurethanes and Potting Compounds

Reacting the trifunctional hydroxyl structure of commercial castor oil with polyisocyanates produces resilient polyurethane potting resins, joint sealants, and elastomeric protective liners with excellent electrical insulation.
