Sulfonated castor oil
Sulfonated castor oil, identified by CAS number 8002-33-3 and widely known as Turkey Red Oil, is a chemically modified vegetable oil produced through the controlled sulfonation of castor oil with sulfuric acid. This process converts the triglyceride into an anionic surfactant, granting it excellent water-dispersibility and emulsifying capabilities that raw castor oil lacks. Typically appearing as a viscous, amber-colored liquid, this material retains the inherent lubricating properties of its parent oil while functioning effectively in aqueous systems. In industrial and research contexts, it is highly valued for its versatility as a wetting agent, dispersant, and lubricant. Handling should follow standard industrial safety protocols, including the use of appropriate personal protective equipment and storage in a cool, well-ventilated environment to ensure chemical stability. As a bio-based raw material, it serves as a functional and reliable alternative to synthetic surfactants across numerous manufacturing sectors.
• Textile and Dyeing Industry: This material acts as a vital wetting and leveling agent during the dyeing and finishing of fabrics. By reducing the surface tension of the dye bath, it facilitates uniform penetration of pigments into fibers, particularly cotton and linen, which helps prevent streaking and ensures consistent color application.
• Leather Processing: In the leather industry, sulfonated castor oil is utilized as a fatliquoring agent. It penetrates the hide to lubricate internal collagen fibers, resulting in finished leather that is soft, flexible, and durable. Its anionic nature allows it to remain stable during various tanning stages, providing necessary lubrication without compromising the structural integrity of the skin.
• Metalworking Fluids: It is frequently employed as an emulsifier and lubricant additive in metalworking formulations. It aids in the creation of stable oil-in-water emulsions used for cooling and lubricating cutting tools, thereby reducing friction, minimizing heat buildup, and extending the operational life of machinery during high-speed processing.
• Personal Care and Agrochemicals: The compound serves as a solubilizer and secondary emulsifier in cosmetic products, such as bath oils and cleansers, where it helps disperse fragrance oils. In agriculture, it is used as a surfactant in pesticide and herbicide formulations to enhance the coverage and adherence of active ingredients on foliage.
