GHS criteria not met
Conclusions:
20% of the animals used at the dose level of 8ml/kg died. LD50 is greater than 8ml/kg
Executive summary:

In this guideline (CFR 1500.3) study the LD0 of the test material was determined to be 8 ml/kg bw. 5 male and 5 female rats were dosed orally by gavage at 8 mL/kg and observed for 2 weeks post-dose. 2 deaths were observed.
