Nonylphenol Ethoxylate NP-9

Nonylphenol Ethoxylate NP-9 (CAS 9016-45-9, molecular formula C15H24O(C2H4O)9) is a formulation raw material used by detergent, personal care and industrial cleaning manufacturers who need stable active matter and reproducible performance. China Chemicals supplies it at Active matter 99% min in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as NP-9, Nonoxynol-9, Nonylphenol Polyethoxylate. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
