Sodium 2-phenylphenate

Sodium 2-phenylphenate (CAS 132-27-4) is the sodium salt of 2-phenylphenol, commercially known under trade names including Dowicide A, Natriphene, and Preventol ON. It carries no assigned E-code for food use and is registered under EC number 205-055-6. It is handled as both a solid and liquid grade depending on concentration.

In water treatment and industrial cleaning, it functions as a broad-spectrum biocide by disrupting microbial cell membranes, inhibiting bacterial and fungal growth at low concentrations. In textile and leather processing, it controls mold and microbial contamination during wet storage and transport. Personal care and agricultural formulations use it as a preservative active against gram-positive bacteria and yeasts.

This material is supplied in compliance with REACH regulations and is available in technical grade. Typical packaging includes drums and IBCs for liquid concentrations, with bag formats for solid material. Buyers should confirm grade specification and regional biocidal product authorization requirements before procurement.
