Description

Castor Oil, Propoxylated is a non-ionic surfactant and polyol derivative produced by the controlled addition of propylene oxide to castor oil. This versatile chemical intermediate is valued for its excellent emulsifying, lubricating, and solubilizing properties, as well as its ability to impart flexibility and hydrophobicity to final formulations. It is a critical raw material for manufacturers in the polyurethane, coatings, and personal care industries seeking bio-based and high-performance components.

Application

• Polyurethane Systems: A key bio-based polyol for flexible foams, elastomers, coatings, and adhesives, offering enhanced flexibility and hydrolytic stability.
• Coatings & Inks: Used as a modifying resin or plasticizer in alkyd paints, polyurethane coatings, and printing inks to improve adhesion, gloss, and water resistance.
• Lubricants & Greases: Serves as a high-performance base oil or additive in biodegradable lubricants, metalworking fluids, and specialty greases.
• Personal Care & Cosmetics: Functions as an emollient, viscosity modifier, and hair conditioning agent in creams, lotions, and hair care products.
• Textile & Leather Processing: Acts as a softening agent, lubricant, and water repellent finish in textile auxiliaries and leather treatments.
• Plasticizers: Employed as a secondary plasticizer and stabilizer in PVC and other polymer compounds to enhance low-temperature flexibility.
