High-efficiency Oleate Ester
Overview
High-efficiency Oleate Ester is a synthetic ester derived from oleic acid, optimized for industrial cleaning and lubrication applications. Its molecular structure combines hydrophobic and hydrophilic properties, making it effective in breaking down oils and greases while remaining environmentally preferable to petroleum-based alternatives. Widely adopted in Europe and North America under REACH and EPA compliant formulations, this ester is increasingly replacing traditional solvents in metal degreasing and parts cleaning due to its lower VOC emissions and superior performance in hard water conditions.
Physical and Chemical Properties
As a low-viscosity liquid with mild odor, High-efficiency Oleate Ester exhibits excellent thermal stability up to 200°C, making it suitable for high-temperature applications. Its flash point typically exceeds 150°C, classifying it as non-flammable under normal storage conditions. The ester demonstrates remarkable hydrolytic stability compared to other vegetable oil derivatives, maintaining effectiveness even in alkaline cleaning systems (pH 8-11). Its iodine value (usually 80-90 g I₂/100g) indicates good resistance to oxidation when properly stabilized with antioxidants.
Main Applications
In industrial cleaning, this ester serves as the active component in precision degreasers for aerospace and automotive components, where residue-free performance is critical. It effectively removes machining oils, coolants, and particulate contamination without damaging sensitive substrates. The lubricant industry utilizes it as a base stock or additive in biodegradable hydraulic fluids and chain lubricants, where its film strength and anti-wear properties outperform conventional mineral oils. Textile manufacturers employ it as a spin finish for synthetic fibers to reduce friction during processing.
Safety and Storage
While classified as non-hazardous under GHS standards, workplace exposure limits should be monitored during high-temperature spraying applications. Proper ventilation is recommended when used in enclosed spaces due to potential aerosol formation. Storage in 200L steel drums or IBC totes requires protection from direct sunlight to prevent UV degradation. Shelf life typically exceeds 24 months when stored below 30°C. Incompatible with strong acids/oxidizers - separate storage is advised.
B2B Procurement Guide
Industrial buyers should specify technical parameters including ester content (≥90%), acid value (<5 mg KOH/g), and peroxide value (<10 meq/kg) to ensure quality consistency. Bulk shipments (20+ metric tons) often qualify for 10-15% price discounts from major chemical distributors. Certifications to request include USDA BioPreferred (for North American markets), EU Ecolabel compliance, and ISO 14001 manufacturing certification. Sample testing for compatibility with existing formulations is strongly recommended before large-scale procurement.
