Polyoxyethylene Nonylphenol (NP-9)
CAS 26027-38-3C15H24O(C2H4O)9617.6 g/mol
Polyoxyethylene Nonylphenol (NP‑9) is a widely used non-ionic surfactant known for its exceptional emulsifying, wetting, and detergent properties. In industrial applications such as cleaning, textile processing, agrochemicals, and more, it facilitates processes by improving the spread and adhesion of formulations. It is particularly valued in the formation of detergents and paints, where its ability to stabilize and enhance texture is crucial. As a versatile agent, NP‑9 supports a wide range of industrial sectors across Kenya and East Africa.
