As part of a health-hazard survey on the health risk of hospital clean
ing workers from exposure to Lyorthol, a hazard assessment of o-phenyl
phenol (and its sodium salt), one of the constituents of Lyorthol, has
been prepared. In this paper, the physical and chemical characteristi
cs, kinetics and effects of o-phenylphenol and its sodium salt are des
cribed and discussed, and an overall, summarizing hazard evaluation is
presented. (C) 1998 John Wiley & Sons, Ltd.
