Extra Pale Grade Castor Oil

Manufactured by Nova Industries

Nova Industries manufactures Extra Pale Grade Castor Oil, a premium quality oil distinguished by its exceptionally light color and low acidity.

This grade is produced exclusively from the first mechanical pressing of high-quality castor seeds, without the use of chemical solvents. The resulting crude oil undergoes a specialized low-temperature refining and bleaching process to preserve the oil’s natural integrity while achieving a color profile significantly lighter than standard commercial grades.

1. Technical Significance

The “Extra Pale” designation refers specifically to the low color value on the Lovibond scale (typically Yellow < 9.0 in a 5.25″ cell).

• Color Stability: Crucial for applications where the final product must remain water-white or transparent. The low pigment content ensures it does not alter the shade of light-colored resins or clear coatings.
• Low Acidity: With a Free Fatty Acid (FFA) content typically below 0.35%, this grade offers superior oxidative stability and reactivity in urethane and esterification reactions.
• Purity: Being a “First Press” oil, it is free from the solvent residues and gums often found in solvent-extracted grades.

2. Industrial Applications

This grade is the preferred choice for industries where aesthetics and purity are non-negotiable.

High-End Coatings & Resins

• Clear Varnishes: Used as a plasticizer and drying oil modifier in non-yellowing clear varnishes and white alkyd enamels.
• Polyurethanes: Acts as a high-purity polyol for transparent casting resins and optical-grade encapsulants.

Cosmetics & Personal Care

• Color Cosmetics: Ideal for use in clear lip glosses and transparent soaps where base oil color must be minimal.

Specialty Chemicals

• Esters: The preferred feedstock for manufacturing light-colored esters (e.g., Butyl Ricinoleate) used in food packaging and medical plastics.
