- 5000 mg/kg
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Observations were 1, 3 and 6 h post application, once daily there after. Weighing was prior to application and at termination of the study
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight - Statistics:
- none
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 000 mg/kg bw
- Mortality:
- 4 of 10 animals died.
day 0 -1: no death occurred
day 2: one male
day 3: one male; one female
day 4: one female
day 5 -14: no death occurred - Clinical signs:
- other: Slight to severe depression of activity was noted for 5 animals. One animal appeard dehydrated on the second and the third day. Muscle tremor was noted for two animals on the second day.
- Gross pathology:
- No pathological changes were observed at necropsy of the surviving animals. Gastrointtestinal irritation and motteld to bleached liver lobes was observed in the animals found dead.
- Executive summary:
Oral toxicity was examined in a guidline study similar to OECD 401. The study is reliable with some minor restriction mainly due to poor documentation of the test substance. Male and female Wistar rats recieved a limit dose of 5000 mg/kg. 4 (2 m/2f) animals died. The LD 50 therfore is > 5000 mg/kg. Gastrointestinal irritation and mottled liver lobes were observed at necropsy.
Conclusion
Dimethanol-divinyl ether of 1,4- cyclohexane is practically non-toxicic after swallowing.

No mortality (LD50 > 2000 mg/kg) and no clinical symptoms were observed. Necropsy reveald no gross findings. Beyond this sight reddening and scaling were observed at application site.
Conclusion
Dimethanol divinyl 1,4-cyclohexane is practically non-toxic after skin contact.

Additional information
Oral toxicity was examined in a guideline study similar to OECD 401 (val 2). Five Male and female Wistar rats recieved a limit dose of 5000 mg/kg . 4/10 (2 m/2f) animals died. The LD 50 was determined to be > 5000 mg/kg. Gastrointestinal irritation and mottled liver lobes were observed at necropsy of animals that died. There were no gross findings in animals that survived.
The acute dermal toxicity was examined in a study similar to OECD Guideline 402 (Val 2). 3 male and female rabbits recieved a limit dose of 2000 mg/kg on abraded and non abraded dorsal skin. No mortality (LD50 > 2000 mg/kg) and no clinical symptoms were observed. Necropsy reveald no gross findings. Beyond this, slight reddening and scaling were observed at application site.
Justification for selection of acute toxicity – oral endpoint
Only one study available
Justification for selection of acute toxicity – dermal endpoint
Only one study available
Justification for classification or non-classification
Classification for acute toxicity is not warranted according to the criteria of EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
