- Executive summary:
In an acute oral toxicity study performed according to test guidelines OECD 423, Ditetrahydrofurylpropane was initially administered by oral gavage to three female Wistar rats at 2000 mg/kg body weight. In a stepwise procedure additional groups of females were dosed at 2000, and 300 mg/kg body weight. All animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed on the day of death or after terminal sacrifice (Day 15). Three (of the six) females dosed at 2000 mg/kg bw were found dead or sacrificed moribund between Days 1 and 2. No mortality occurred at 300 mg/kg bw. The surviving animals had recovered from the clinical symptoms between Days 3 and 7. The mean body weight gain shown by the surviving animals over the study period was considered to be normal. No substance related abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 value of Ditetrahydrofurylpropane in Wistar rats was established to be within the range of 300-2000 mg/kg body weight. According to the OECD 423 test guideline the LD50 cut-off value was considered to be 2000 mg/kg body weight.

In a stepwise procedure additional groups of females were dosed at 2000, and 300 mg/kg body weight. All animals were subjected to daily observations and weekly determination of body weight.

The surviving animals had recovered from the clinical symptoms between Days 3 and 7. The mean body weight gain shown by the surviving animals over the study period was considered to be normal. No substance related abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 value of Ditetrahydrofurylpropane in Wistar rats was established to be within the range of 300-2000 mg/kg body weight. According to the OECD 423 test guideline the LD50 cut-off value was considered to be 2000 mg/kg body weight. Therefore, the oral LD50 was set to be between 300 and 2000 mg/kg bw.
Dermal:
In an acute dermal toxicity study performed according to OECD 402 test guidelines, Ditetrahydrofurylpropane was administered to five Wistar rats of each sex by a single dermal application at 2000 mg/kg body weight for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15). No mortality occurred. Hunched posture, piloerection, chromodacryorrhoea, ptosis, and/or lethargy were noted in four males and 2 females on Days 1 and/or 2. The body weight gain during the observation period was within the range expected for rats used in this type of study. No abnormalities were found at macroscopic post mortem examination of the animals. The dermal LD50 value of Ditetrahydrofurylpropane in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for classification or non-classification
Based on the available data the substance is classified for Acute toxicity Category 4, H302 according to CLP Regulation (EC) 1272/2008. According to the same regulation, no classification for Acute dermal toxicity is required.
