The Scantox study (1982e) is considered to be reliable and does not show 4-chloro-o-cresol to be a sensitiser.The BUA-Stoffbericht 134 report (1994) cited in the EU Risk Assessment Report from the Rapporteur Member State reports a further negative sensitisation study, however this has not been reported correctly and so cannot be fully reported for inclusion.


No classification is required with respect to sensitisation.
