Vitro Dermal Absorption Rate Testing of Certain Chemicals of Interest 
to the Occupational Safety and Health Administration. Data were 
received on the following chemicals: Biphenyl (CAS No. 92-52-4); tert-
butylcatechol (TBC) (CAS No. 98-29-3); carbon disulfide (CAS No. 75-15-
0); catechol (CAS No. 120-80-9); chlorobenzene (CAS No. 108-90-7); 
cyclohexanol (CAS No. 108-93-0); p-dichlorobenzene (CAS No. 106-46-7); 
dimethylacetamide (DMAc) (CAS No. 127-19-5); ethylene dichloride (CAS 
No. 107-06-2); hydroquinone monomethyl ether (HQMME) (CAS No. 150-76-
5); methyl formate (CAS No. 107-31-3); vinyl toluene (CAS No. 25013-15-
