Cold Pressed Castor Oil

What Cold Pressed Castor Oil Does & Buyer Problems It Solves

What It Does:

• Provides deep moisturization and skin nourishment – the high ricinoleic acid content penetrates deeply into the skin and hair shaft, delivering intensive hydration, reducing transepidermal water loss, and conditioning dry or damaged tissue.
• Supports scalp health and hair growth – cold pressed castor oil is widely used in hair care for promoting hair thickness, reducing scalp dryness and dandruff, and strengthening hair follicles through its anti-inflammatory and antimicrobial fatty acid profile.
• Delivers antioxidant and anti-inflammatory activity – natural tocopherols and ricinoleic acid in cold pressed castor oil help reduce inflammation when applied topically, making it suitable for sensitive skin formulations and wound-care adjacent applications.

Buyer Problems It Solves:

• If your cosmetic or personal care formulation requires a 100% natural, solvent-free castor oil that resonates with clean beauty consumers – cold pressed castor oil carries the natural extraction story that heat-refined grades cannot.
• If your supplier’s cold pressed castor oil has an inconsistent colour, odour, or ricinoleic acid content – Nova Industries’ controlled cold pressing and batch testing ensures uniform quality across large and recurring orders.
• If you’re developing products for markets requiring no chemical extraction residues (hexane-free, solvent-free) – our cold pressed oil is purely mechanically extracted, with no chemical solvents used at any stage.
• If you need cold pressed castor oil with organic certification for use in certified natural or organic formulations – we offer organically certified cold pressed castor oil alongside our conventional cold pressed range.

Key Properties & Performance Characteristics

• Appearance: Pale to light yellow, clear to slightly hazy, thick viscous liquid
• Ricinoleic Acid Content: 85–90% – preserved through cold pressing without thermal degradation
• Acid Value: ≤ 4 mg KOH/g (low free fatty acids indicating fresh, good-quality oil)
• Saponification Value: 176–187 mg KOH/g
• Iodine Value: 82–90 g I₂/100g
• Specific Gravity (25°C): 0.957–0.962
• Viscosity: High natural viscosity – typical of unadulterated cold pressed castor oil
• Peroxide Value: ≤ 5 meq O₂/kg (freshness indicator)
• Extraction Method: Mechanical cold press – no hexane, no solvents
• Tocopherols: Naturally preserved – contributes to oxidative stability and skin benefit

Stability, Shelf Life & Storage

• Shelf Life: 18–24 months from production date under recommended storage
• Storage Temperature: 15°C–25°C in a cool, dry, shaded environment
• Light Protection: Store in dark amber glass, opaque HDPE, or light-shielded MS containers – UV exposure accelerates peroxide formation
• Oxidation: Cold pressed oil has slightly lower oxidative stability than refined grades due to natural tocopherol content – reseal containers promptly after use
• Temperature Fluctuations: Avoid repeated freeze-thaw cycles which can affect clarity
• Packaging Options: 1 litre HDPE bottles, 5 litre HDPE cans, 200 kg MS drums – custom packaging available for bulk cosmetic manufacturers

Manufacturing & Quality Control

Cold Pressed Castor Oil at Nova Industries is produced through the following process:

• Seed Selection: Carefully selected Ricinus communis seeds – non-GMO and tested for aflatoxin and heavy metal content
• Cold Pressing: Mechanical extraction at controlled low temperatures (below 60°C) to preserve natural composition
• Settling & Filtration: Natural settling followed by fine filtration to achieve target clarity without bleaching or deodorization
• No Solvent Use: No hexane, no chemical solvents, no high-temperature processing
• Batch Testing: Acid Value, Peroxide Value, Iodine Value, Colour, Saponification Value, Moisture tested per batch
• Certifications: Certificate of Analysis (CoA) per batch; organic certification available; MSDS provided
