Test material
- Reference substance name:
- 3,6,9-trioxaundecane-1,11-diol
- EC Number:
- 203-989-9
- EC Name:
- 3,6,9-trioxaundecane-1,11-diol
- Cas Number:
- 112-60-7
- Molecular formula:
- C8H18O5
- IUPAC Name:
- 2,2'-[oxybis(ethane-2,1-diyloxy)]diethanol
- Test material form:
- liquid
Constituent 1
- Specific details on test material used for the study:
- - Source: the test substance is obtained from UCC plant in Texas City , TX (sample no. 48-349)
Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Weight at study initiation: 2.0 - 3.0 kg
- Diet: appropriate commercial diet
- Water: municipal water
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- Rabbits were subjected to 24 hours of contact with the test material which is retained under impervious sheeting on the clipped, intact skin of the trunk. As necessary for larger doses, gauze is wrapped around the trunk over the sample to prevent leakage. Vetrap® Bandaging Tape is wrapped over the impervious sheeting and the animal is returned to its cage for the contact period.
- Duration of exposure:
- 24 h
- Doses:
- 16 mL/kg
- No. of animals per sex per dose:
- 5
- Control animals:
- not specified
- Details on study design:
- After the contact period, excess fluid is removed to diminish ingestion. Observations for skin reaction are made at one hour, 7 days and 14 days after the contact period. Five male and 5 females are included on each level used for the LD50 calculation. Animal weights are recorded at 0 days (before dose), 7 days and 14 days (just prior to sacrifice). At death or sacrifice, each animal is subjected to gross pathologic evaluation.
- Statistics:
- LD50's and the estimated LD50 slopes are calculated by the moving average method (Thompson, 1947; Weil, 1983) and are based on a 14-day observation period.
