Description
A Fungicide and Bactericide. Ortho-phenyl phenol (OPP) inhibits the growth of fungi and bacteria. It is effective at concentrations as low as 0.05% by weight. OPP is an ingredient in Lysol® and has been used as a fungicides in Starch, Glue, and Polyvinyl acetate emulsions. Dilute solutions have also been used for removing lichens from Granite. OPPNa, the sodium salt of ortho-phenyl phenol, is more soluble.
