Pale Pressed Grade Castor Oil (PP)

Overview

CanCastor's Pale Pressed Grade Castor Oil (PP) stands as a testament to unparalleled purity and superior performance in industrial applications. Sourced from the meticulously controlled first pressing of premium Ricinus communis seeds, this exceptional oil is distinguished by its remarkably lighter color and low acidity, indicating minimal degradation and excellent oxidative stability. As a naturally derived triglyceride primarily composed of ricinoleic acid (an 18-carbon unsaturated fatty acid with a hydroxyl group), Pale Pressed Castor Oil (PP) (INCI: Ricinus Communis (Castor) Seed Oil, CAS: 8001-79-4) offers unique bifunctional chemistry.

Its characteristic hydroxyl functionality and double bond impart exceptional versatility, making it a cornerstone ingredient across a diverse range of chemical syntheses and product formulations. CanCastor leverages its deep industrial chemistry expertise and robust global supply chain to deliver a PP grade that consistently exceeds rigorous industry benchmarks for quality and performance. Our clients across various sectors, from high-performance coatings to advanced lubricants and specialty polymers, rely on CanCastor's PP grade for its consistent quality, enabling predictable and superior end-product characteristics. This grade is specifically engineered to meet the demanding requirements of technical and industrial applications where color, low acidity, and consistent reactivity are paramount, ensuring optimal results in your most critical processes.

Key Physical & Chemical Properties

CanCastor's Pale Pressed Grade Castor Oil (PP) is rigorously tested to ensure adherence to stringent quality parameters:

• Acid Value: Max 2.0 mg KOH/g – Indicative of low free fatty acid content, crucial for stability and minimizing side reactions in polymer synthesis.
• Hydroxyl Value: 160-168 mg KOH/g – Measures the concentration of hydroxyl groups, vital for reactive applications, especially in polyurethane chemistry.
• Iodine Value: 82-90 g I2/100g – Reflects the degree of unsaturation, relevant for oxidative crosslinking and chemical modification.
• Saponification Value: 176-187 mg KOH/g – Represents the total ester content, confirming the high purity of the triglyceride structure.
• Specific Gravity (25°C): 0.956-0.963 – Essential for precise formulation and blending calculations.
• Color (Gardner): Max 2 – A remarkably light color profile, critical for applications requiring clear or light-colored end products.
• Viscosity (25°C): 630-880 cP – Defines the rheological behavior, impacting processability and the flow characteristics of finished formulations.
• Moisture Content: Max 0.25% – Ensures product integrity, preventing unwanted hydrolysis and degradation during storage and use.
