Administration / exposure
- Type of coverage:

- Details on dermal exposure:
- The backs of the animals were shaven (approximately 10 % area of the total body surface) 24 hours prior to the treatment. The test item was applied in a single 2000 mg/kg bw dose uniformly over the shaved skin throughout a 24- hour exposure period. Sterile gauze pads were placed on the skin of the rats. These gauzes were kept in contact with the skin by a patch with adhesive hypoallergenic plaster. The entire trunk of the animal was wrapped with semi-occlusive plastic wrap for 24 hours. At the end of the exposure period, residual test item was removed, using body temperature water.
- Duration of exposure:
- 24 hours
- Doses:
- Preliminary test: 5, 50, 300, 2000 mg/kg bw
Main test: 2000 mg/kg bw - No. of animals per sex per dose:
- Preliminary test: 2 (females)
Main test: 5 - Control animals:
- no
- Details on study design:
- Observations:
- Mortality: Inspection for signs of morbidity and mortality were made twice daily at the beginning and end of the working day.
- Clinical observations: Careful clinical observation was made at the following intervals: 1h, 5h after the treatment and once each day for 14 days thereafter. Individual observations included the skin and fur, eyes and mucous membranes, and also respiratory, circulatory, autonomic and central nervous system, somatomotor activity and behaviour pattern. Particular attention was directed to the observation of tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma.
- Body weight: The body weight was recorded on day 0 (shortly before treatment), on day 7 and on day 14 with a precision of 1 g in the main study.
- Pathology: At the end of the observation period all rats of the main study were sacrificed under isofluran anaesthesia. After examination of the external appearance, the cranial, thoracic and abdominal cavities were opened and the appearance of the tissues and organs was observed, and any abnormality was recorded with details of its location, colour, shape and size. - Statistics:
- No statistical analysis has been performed.

Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: No behavioural changes or systemic toxic signs were noted during the study. Dermal irritation symptoms as erythema and other signs were observed in all animals on the treatment site. The redness was detected between Day 1 and Day 7 in males and between Da
- Gross pathology:
- All animals survived until the scheduled necropsy on Day 14. No pathological changes were found related to the effect of the test item during the macroscopic examination of male animals. No macroscopic alterations due to the systemic toxic effects of the test item were found in females, but external necropsy findings were detected on site of the administration. Wounds on the treated area were observed in all females. Very slight redness were recorded in two animals, well defined erythema was detected in one animal and moderate to severe erythema was observed in two animals. Slight hydrometra was observed in two females and moderate hydrometra was found in two females. Hydrometra was an indication for the sexual cycle of female animals and is a frequent observation in experimental rats with no toxicological meaning.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The dermal LD50 of the test item, observed in a GLP compliant OECD 402 study, is >2000 mg/kg bw .
- Executive summary:
In a GLP compliant acute dermal toxicity study performed according to OECD 402, 5 male and 5 female Wistar rats were exposed to
Polypropoxylated p-nonylphenol-formaldehyde-diethanolamine, Mannich base at 2000 mg/kg bw by the dermal route. The test item, dissolved in sunflower oil was applied semi-occlusive and left in contact with the skin for 24 hours, followed by a 14-day observation period. No mortalities occurred. No behavioural changes or systemic toxic signs were noted during the study. Dermal irritation symptoms as very slight to well defined erythema in males and very slight to severe erythema in females were observed on the treatment site. These symptoms were observed in the first week in males and throughout the 14-day observation period in females. Other signs as wounds and/or crusting appeared in males between Day 2 and Day 12. Wounds occurred in all females between Day 1 and Day 14. The body weight development was undisturbed in all male animals. The body weight loss was observed in all females in the first week and in one female in the second week. Four animals did not regain its original body weight. No treatment-related macroscopic alterations of organs and tissues were seen during necropsy. The external alterations (erythema, wounds) occurred in females were in line with the observed local irritant symptoms. Under the experimental conditions, the acute dermal LD50 value of
Polypropoxylated p-nonylphenol-formaldehyde-diethanolamine, Mannich base is determined to be greater than 2000 mg/kg bw.
