Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Remarks:
- male
- Details on test animals or test system and environmental conditions:
- Animals:
Species: Albino rabbit, New Zealand White, (SPF-Quality). Recognized by international guidelines as the recommended test system (e.g. EC, OECD). Source: Charles River Deutschland, Kisslegg, Germany. Number of animals: 3 Males. Age and body weight: at least 6 weeks old and at least 1.0 kg. Identification: earmark. Health inspection: performed prior to the commencement of treatment, to ensure that the animals were in a good state of health. Special attention was paid to the skin to be treated, which was intact and free from abnormalities.
Conditions:
Environmental controls for the animal room were set to maintain 18 to 24°C, a relative humidity of 40 to 70%, approximately 15 room air changes/hour, and a 12-hour light/12-hour dark cycle. Any variations to these conditions were maintained in the raw data and had no effect on the outcome of the study. Accommodation: animals were individually housed in labeled cages with perforated floors (Ebeco, Germany, dimensions 67 x 62 x 55 cm) and shelters (Ebeco, Germany, dimensions 40 x 32 x 23 cm). Acclimatization period was at least 5 days before start of treatment under laboratory conditions. Diet: pelleted diet for rabbits (Global Diet 2030 from Harlan Teklad®, Mucedola, Milanese, Italy) approximately 100 grams per day. Hay (TecniLab-BMI BV, Someren, The Netherlands) and wooden sticks (Swedish aspen wood, Bioservices, Uden, The Netherlands) were available during the study period. Water: free access to tap water. Diet, water and cage enrichment evaluation for contaminants and/or nutrients was performed according to facility standard procedures. There were no findings that could interfere with the study.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: untreated skin of each animal
- Amount / concentration applied:
- 0.5 mL
- Duration of treatment / exposure:
- 4h
- Observation period:
- 1, 24, 48 and 72 hours after exposure
- Number of animals:
- 3
- Details on study design:
- The study was performed in a stepwise manner and was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner 7 days later, after considering the degree of skin irritation observed in the first animal.

- Irritant / corrosive response data:
- Irritation:
Four hours exposure to 0.5 mL of the test substance resulted in very slight erythema in the treated skin areas of the three rabbits on Day 1. No oedema was noted.
Corrosion:
No evidence of a corrosive effect on the skin. - Other effects:
- Coloration / Remnants:
No staining of the treated skin by the test substance was observed. Sticky remnants of the test substance were present on the skin on Day 1 and 2.
Toxicity / Mortality:
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.
Any other information on results incl. tables
The results were evaluated according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations and the EC criteria for classification and labelling of dangerous substances and preparations (Council Directive 67/548/EEC and all adaptations to technical progress and amendments of this Directive published in the Official Journal of the European Union).
Applicant's summary and conclusion

- - does not have to be classified
- Executive summary:
A study was conducted to determine the skin irritation/corrosion potential of the test substance according to OECD Guideline 404, EU Method B.4 and EPA OPPTS 870.2500. Three New Zealand White rabbits were exposed to 0.5 ml test substance by application onto clipped skin (150 cm2 area) for 4 h using a semi-occlusive dressing. The untreated skin of each animal served as the reference control. Four hours after application, the dressing was removed and the skin cleaned of residual test substance using tap water. Skin reactions were assessed 1, 24, 48 and 72 h after exposure. Exposure to 0.5 mL of the test substance resulted in very slight erythema in the treated skin areas of the three rabbits on Day 1. No oedema was noted. No corrosive effects on the skin were observed. Under the study conditions, the test substance was considered as not irritating to skin (van Huygevoort, 2012).
