Test animals
- Species:
- rat
- Strain:
- other: CFY
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- - Source: Interfauna UK Limited, Huntingdon, Cambridgeshire, UK
- Age at study initiation: approx. 6 - 8 weeks
- Weight at study initiation: 200 - 245 g
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- water
- Details on dermal exposure:
- The compound was administered either unchanged at a volume of 0.63 mL/kg (= 500 mg/kg) or in water at a volume of 5 mL/kg (=2000 mg/kg).
Since the compound is described as corrosive and dermal irritative reactions were noted in the 500 mg/kg group (undiluted test material), dilution
for testing of the acute dermal toxicity at 2000 mg/kg bw is justifiable.

REMOVAL OF TEST SUBSTANCE
- Washing (if done): yes

Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- No deaths occured during the study.
- Clinical signs:
- other: 500 mg/kg/bw: no clinical signs throughout observation period 2000 mg/kg/bw: hunched posture, abnormal gait (waddling), lethargy, and decreased respiratory rate (shortly after treatment, free of symptoms thereafter)
- Gross pathology:
- Terminal autopsy revealed slight bruising in the subcutaneous tissue of one male and one female rat dosed at 500 mg/kg bw and scab formation with or without ulceration was seen in all rats dosed at 2000 mg/kg bw.
An area of minimal congestion of the stomach (mucosal aspect) was seen in one female rat dosed at 2000 mg/kg bw. - Other findings:
- Dermal reactions:
necrosis in all rats dosed at 500 mg/kg bw, persisting until day 12
well defined to moderate oedema in rats dosed at both levels
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute lethal dermal dose (LD 50) of Amine KK to rats was greater than 2000 mg/kg body weight
- Executive summary:
In a GLP-compliant study similar to OECD TG 402, the test compound Amine KK (cocoalkylamine), a yellow liquid (purity 100%), was dermally applied under occlusion to Sprague-Dawley rats. At a dose level of 500 mg/kg body weight, the test material was applied undiluted (application volume 0.63 ml/kg bw), at a dose level of 2000 mg/kg bw the substance was diluted to a 40% solution (w/v) in distilled water (application volume 5 ml/kg). Compared to a regular OECD TG 402 study a reduced number of animals was used (4 instead of 5 animals/dose). There were no mortalities, hence, the LD50 is > 2000 mg/kg bw. No clinical signs were observed at 500 mg/kg bw. At 2000 mg/kg, hunched posture, abnormal gait, lethargy and decreased respiratory rate were noted. Signs of dermal reactions at the application site of both treatments were well defined to moderate oedema until days 4-5. Hard scabs, persisting to the end of the observation period, frequently prevented the assessment of oedema
