Chemax EM-1169 is a premium surfactant blend that delivers effective emulsification, wetting, and dispersion in industrial and metalworking formulations. Supplied as a clear, yellow liquid, it is ideally suited for producing stable vegetable oil emulsions, including soybean oil systems. Chemax EM-1169 provides excellent hard-water stability and broad system compatibility with various process chemistries in the metalworking industry. The surfactant also disperses easily in water.
Many vegetable oil-based cleaners, metalworking fluids, and textile formulations rely on suitable emulsifiers to prevent emulsion instability, resulting in separation or creaming. In hard-water applications, many surfactants tend to form insoluble salts that precipitate and impact product performance.
