Emulsifier OP-7, chemically characterized as an Octylphenol ethoxylate with an average of seven ethylene oxide units, is a non-ionic surfactant valued for its high chemical stability and emulsifying properties. Frequently designated in industrial safety data sheets as Polyoxyethylene octyl phenyl ether, Octoxynol-7, or Ethoxylated octylphenol, this liquid agent functions as a penetrating detergent in textile processing and a heavy-duty emulsifier in metalworking fluids. We offer bulk supply of this surfactant with competitive factory pricing, customized specifications for hydroxyl value control, and regulatory support documents including MSDS, TDS, COA.

Product Description
Emulsifier OP-7 is supplied as an octylphenol ethoxylate nonionic surfactant used in industrial chemical systems requiring surface activity, emulsification, wetting, penetration, and formulation compatibility. It is generally positioned as an industrial surfactant raw material rather than as a consumer-facing finished ingredient.
This product is commonly applied in textile auxiliaries, industrial cleaning systems, metalworking fluids, and related formulation environments where nonionic compatibility and processing performance are required. Technical documents such as COA, TDS, and SDS may be provided according to the supplied grade.
