  • Applications

    Aluminum oleate, CAS 688-37-9, is a metal soap of oleic acid used as a thickener and rheology modifier in oil- and solvent-based systems. In coatings and printing inks, it helps control viscosity and stabilize formulation structure. In cosmetics and personal care, it serves as a thickener for gels and creams, improving the feel and stability of products. In polymers and plastics, it can function as a processing aid and stabilizer, aiding processing and thermal stability in certain formulations. As a metal soap, it is used as a lubricant-thickener in lubricants and greases, providing viscosity and film-forming properties. It may also be employed as an auxiliary additive in adhesives or sealants to adjust rheology and compatibility of formulations.
