OPP-10 Octylphenol Polyoxyethylene Ether Phosphate is an anionic surfactant prepared by phosphating and modifying octylphenol polyoxyethylene ether (OP-10), with CAS number 51811-79-1. The product appears as a light yellow to yellow viscous liquid. Its molecular structure contains both ether bonds (nonionic hydrophilic groups) and phosphate ester groups (anionic hydrophilic groups). This unique "dual hydrophilic" structure imparts the dual characteristics of nonionic and anionic surfactants to the product.
The core performance of this product is manifested in three aspects: first, excellent emulsifying ability and dispersion stability, allowing efficient emulsification of various oily substances in the aqueous phase and maintaining long-term emulsion stability; second, outstanding wetting and penetrating properties, rapidly reducing interfacial tension to quickly spread and penetrate liquids; third, superior chemical tolerance—maintaining stable interfacial activity under acidic, alkaline, and hard water conditions. This characteristic makes it particularly outstanding in complex working environments.
In addition, OPP-10 also integrates additional functions such as antistatic and anti-rust/corrosion inhibition. In textile processing, it can effectively eliminate static electricity accumulation on fibers; in metalworking fluids, it provides short-term rust protection, truly achieving "multi-purpose use" and helping downstream users simplify formulations and reduce costs.
