- Executive summary:
Justification for read across
Treated distillate aromatic extracts (TDAEs) are a further processing of untreated distillate aromatic extracts (UDAEs) in an attempt to reduce the amount of 3-7 ring PAC that is present. Since the treatment is mostly a selective reduction of PACs, the data from UDAEs can serve as read across where treatment was insufficient and a significant amount of PACs still remain (≥ 3 wt% DMSO extractables as measured by IP-346). Where treatment was sufficient to reduce the 3-7 ring PACs (<3 wt% DMSO extractables as measured by IP-346), the material is most similar to a lubricating base oil and it is this data that should be used for read across.
Male and female rats were administered a single oral dose of undiluted distillate aromatic extract at a dose of 5000 mg/kg bw. There were no deaths during the 14 day observation period.
No treatment-related lesions were observed at gross necropsy.
The LD50 of the test material was > 5000 mg/kg.
