Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- TEST SITE
- Area of exposure: 6 x 6 cm² clipped skin of the dorsal area of the trunk
- % coverage: 10
- Type of wrap if used: the test material was held in contact with the skin with surgical gauze and a piece of self adhesive bandage
REMOVAL OF TEST SUBSTANCE
- Washing: residual test material was removed with cotton wool moistened with arachis oil BP
- Time after start of exposure: 24 h - Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg bw
- 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: The animals were observed for deaths or overt signs of toxicity 30 min, 1, 2 and 4 h after dosing and subsequently once daily for 14 days. Body weights were recorded prior to treatment and on Day 7 and 14 after dosing.
- Necropsy of survivors performed: Yes, all animals were subjected to gross necropsy.
- Other examinations performed: After removal of the dressings and subsequently once daily for 14 days, the test sites were examined for evidence of primary irritation and scored according to Draize scoring system.
Results and discussion
- Preliminary study:
- One male and one female rat were initially treated with the test item at a dose level of 2000 mg/kg bw. As no mortalities were noted a further group of animals (four males and four females) was similarly treated with the test item at a dose level of 2000 mg/kg bw to give a total of five males and five females.
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred during the study period.
- Clinical signs:
- other: No clinical signs of toxicity were observed up to the end of the 14-day observation period.
- Gross pathology:
- No abnormalities were noted at necropsy.
- Other findings:
- - Primary irritation: Signs of dermal irritation included very slight to well defined erythema, slight edema, scattered areas of green necrosis, scattered areas of blanching, small scattered superficial scabs, hardened light and dark brown colored scabs, scab cracking, scab lifting to reveal glossy skin, dried blood and/or bleeding, crust formation and desquamation. Adverse dermal reactions prevented the accurate evaluation of erythema and edema at the treatment sites of two male and two female animals.
Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No. 1272/2008
- Conclusions:
- CLP: not classified
