Zinc ricinoleate, as the name suggests, is a compound formed by the chemical reaction between ricinoleic acid (also known as 12-hydroxy-9-octadecenoic acid) and zinc ions. Ricinoleic acid, as an unsaturated fatty acid, mainly exists in castor oil and has good lubricity, stability and biodegradability. Zinc, as an important trace element, plays multiple key roles in living organisms, such as participating in enzymatic reactions and maintaining the health of the immune system. The combination of the two enables zinc ricinoleate to perform outstandingly in terms of chemical stability, lubricity, and oxidation resistance. Chemically, zinc ricinoleate usually appears as a white or light yellow powder-like solid, with good solubility and thermal stability. This compound not only retains the natural advantages of ricinoleic acid but also enhances its chemical activity and application scope through the introduction of zinc.
