A readily biodegradable, nonionic NPE-replacement surfactant for heavy-duty degreasing and hard-surface cleaning — engineered to drop in for NP9 or NP10.

Berol® 609 is a nonionic alcohol-ethoxylate blend built to do one job exceptionally well: replace nonylphenol ethoxylates (NP9 / NP10) without reformulating around them. It is engineered to match their key surfactant properties — low surface tension and a low critical micelle concentration for fast wetting and oil release — so it drops straight into existing degreaser and hard-surface formulations.
What sets it apart is not a single headline cleaning number — in Nouryon’s own comparative work its raw cleaning is as good as the best alcohol-ethoxylate competitors. The real, repeatable advantages are practical and formulation-level: superior high-temperature stability of the finished cleaner (it stayed clear at 50°C where competitors clouded), very fast cold-water dissolution (≈3 s vs 76 s for NP9 at 5°C), fast emulsification and “break” of used motor oil, and complete water solubility that removes the need for a hydrotrope. Add readily-biodegradable status and TSCA/DSL listing, and Berol 609 becomes a compliance-driven upgrade that is easier to make and more robust in the drum.

In Nouryon’s comparative study against NP9 and competitor alcohol ethoxylates (Norfox 609, Tomadol 900/901/902), the cleaning performance of Berol 609 was always at least as good as the alternatives, with its clearest advantage in high-temperature stability of the cleaning formulation; NP9 performed consistently worse on wetting. Berol 609 also showed one of the fastest oil “break” rates on used motor oil. Full datasets are available on request.
