  • Applications

    Chemical name: Ricinoleic Acid - CAS number: 141-22-0. Ricinoleic acid is a hydroxy fatty acid derived from castor oil and serves as a versatile building block in industrial chemistry. It is widely used as a feedstock to synthesize polyurethane polyols for coatings, adhesives, and flexible foams; as a precursor for plasticizers in PVC and other polymers; as a basis for surfactants and detergents used in household and personal-care products; as a component in alkyd and oil-based coatings and inks; as a starting material for lubricants and lubricant additives; and in cosmetics and personal care as emollients and texture-enhancing ingredients. Subject to local regulations and formulation limits.
