Molecular formula: C18H36O3
Molecular weight: 300.48
Raw material source: obtained through hydrogenation, saponification, and acid refining of castor oil
Physicochemical properties
Appearance: White flake / crystalline solid with a slight oily odor
Melting point: 74~76°C
Boiling point: 180°C (decomposition)
Flash point: 231.8°C
Density: 1.0238 g/cm³
Solubility: Insoluble in water; soluble in ethanol, ether, chloroform, mineral oil, and organic solvents
Characteristics: The molecule contains both carboxyl and hydroxyl bifunctional groups, making it highly prone to salt formation with metal ions. It exhibits exceptional gelling and thickening properties, along with excellent thermal stability and resistance to acidification and oxidation
Core Product Advantages
- The bifunctional group structure is the core raw material for producing lithium-based grease, resulting in grease with high dropping point, water resistance, anti-compression properties, and minimal loss;
- The paste exhibits excellent performance, with a fine and stable texture that resists layering under both high and low temperature conditions;
- Low chroma and low impurities, suitable for high-end cosmetics and color cosmetics;
- Low toxicity, good biocompatibility, suitable for daily chemical and pharmaceutical auxiliaries.
Key Application Areas
