Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the results of the study, since there were no mortalities observed as a result of systemic toxicity caused by the test substance, the dermal LD50 value of Rosin Amine 90 in male and female Wistar rats was established to be more than 2000 mg/kg bw. According to GHS and EC Regulation No. 1272/2008, the test substance does not have to be classified and has no obligatory labelling requirements for acute dermal toxicity.
- Executive summary:
This study was conducted to assess the systemic toxicity of the test substance, Rosin Amine 90, in a process carried out in accordance with the following guidelines; OECD No.402 (1987) "Acute Dermal Toxicity", Commission Regulation (EC) No 440/2008, B3: "Acute Toxicity (Dermal)", EPA, OPPTS 870.1200 (1998), "Acute Dermal Toxicity" and JMAFF Guidelines (2000), including the most recent revisions. The study was thought to provide a rational basis for risk assessment in humans, since the dermal route is a possible route of exposure during the manufacture, handling or use of the test substance.
Rosin Amine 90 was administered to five Wistar rats of each sex by a single dermal application at 2000 mg/kg body weight for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed on the day of death or after terminal sacrifice (Day 15).
The main clinical signs observed for all animals from Day 1 -3 were flat posture, hunched posture and/or chromodacryorrhoea. Additionally, one animal showed hunched posture up to Day 8. During he observation period, general erythema, erythema maculate, scales, scabs, thickened areas, fissures, wounds and/or brown staining were noted in the treated skin-area of the animals. In addition, one animal had scabs on the left flank during the observation period. Two animals (one male and one female) were sacrificed for human reasons on Day 6, but there were no mortalities as a result of systemic toxicity caused by the test substance. The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity. There were no abnormalities found during the macroscopic post-mortem examination of the animals.
Since no mortality occurred due to systemic toxicity by the test substance, the dermal LD50 value of Rosin Amine 90 in male and female Wistar rats was established to be more than 2000 mg/kg body weight. Based on these results, Rosin Amine 90 does not have to be classified and has no obligatory labelling requirement for acute dermal toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).
