The cancer weight of evidence determination for mixed xylenes is group D- not classifiable as to human carcinogenicity by the Guidelines for Carcinogen Risk Assessment (1986) and data are inadequate for an assessment of human carcinogenic potential due to conflicting evidence by the revised draft Guidelines for Carcinogen Risk Assessment (1999).
There is limited information on the relative toxicity of the individual isomers and the results are inconsistent. Based on available data, there do not appear to be susceptible populations.
