Overview
Rapeseed oil acid, chemically known as erucic acid, is a monounsaturated fatty acid primarily derived from rapeseed and mustard seed oils. It is characterized by a 22-carbon chain with one double bond at the omega-9 position. Historically, erucic acid was abundant in traditional rapeseed oil, but modern low-erucic acid varieties (like canola oil) have reduced its dietary presence. In industrial contexts, rapeseed oil acid is valued for its chemical stability and versatility. It serves as a precursor for various derivatives used in lubricants, surfactants, and plasticizers. Its non-food applications dominate the market, particularly in Europe and Asia, where it is produced on a large scale.
Physical and Chemical Properties
Erucic acid is a viscous, oily liquid at room temperature, with a faint odor. Its high molecular weight contributes to its stability and resistance to oxidation, making it suitable for long-term storage under proper conditions. The acid is insoluble in water but dissolves readily in organic solvents like ethanol, ether, and chloroform. Key chemical properties include its reactivity with bases to form salts (erucates) and its ability to undergo hydrogenation to produce behenic acid. Its melting point (33-34°C) and boiling point (381°C) reflect its suitability for high-temperature applications, such as industrial lubricants and coatings.
Main Applications
Rapeseed oil acid is extensively used in the manufacturing of lubricants, particularly for high-pressure and marine environments, due to its thermal stability and adhesion properties. It is also a key ingredient in surfactants and emulsifiers, where its long carbon chain enhances surface activity. In the plastics industry, erucic acid derivatives act as plasticizers, improving flexibility in PVC and other polymers. Additionally, it finds niche applications in cosmetics (e.g., hair conditioners) and pharmaceuticals (e.g., drug delivery systems). Its use in biodiesel production is limited due to crystallization issues at low temperatures.
Safety and Storage
While erucic acid is not highly toxic, prolonged skin contact or inhalation of vapors can cause irritation. Proper personal protective equipment (PPE), including gloves and goggles, is recommended during handling. Storage should be in tightly sealed containers, away from heat sources and oxidizing agents, to prevent degradation. Regulatory limits exist for erucic acid in food products (e.g., EU restricts it to ≤5% in edible oils), but industrial-grade applications face fewer restrictions. Spills should be contained with absorbent materials and disposed of according to local environmental guidelines.
B2B Procurement Guide
When sourcing rapeseed oil acid, prioritize suppliers with certifications like ISO or GMP, especially for pharmaceutical or cosmetic applications. Specify purity requirements (typically 90-99%) and request COA (Certificate of Analysis) to verify quality. Bulk purchases (e.g., drums or totes) often reduce costs, but ensure storage capacity aligns with shelf-life considerations. Regional suppliers in Europe (e.g., Germany, France) and Asia (e.g., China, India) dominate the market. Compare prices and logistics options, as shipping viscous liquids may require temperature-controlled transport. For niche uses, consider derivatives like erucamide or glycerol monoerucate, which offer enhanced functionality.
