Constituent 1
- Specific details on test material used for the study:
- Two 50 g samples of the test substance were received from the sponsor on April 9, 1987. Each sample was designated: "metachlooperbenzoe zuur", Ch 04.87.006J. The test substance was named m-chloroperoxybenzoic acid.
Just prior to application, the test substance was moistened with water in a ratio of 1: 1 (w/w) , to ensure good contact with the skin of the rabbits.
Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Healthy male, young adult, New Zealand White albino rabbits obtained from ENKI-Konijnenfarm, Someren, the Netherlands, were used as the experimental animals. The body weight range was 2500-3500 g. The animals were identified by earmarking, and subsequently housed individually in suspended, galvanized cages, fitted with a wire-mesh floor and front. The cages were placed in a room, controlled for light (12 hours light/12 hours dark cycle), temperature (18 ± 3°C), ventilation (c. 10 air changes/hour) ,and relative humidity (at least 40%) throughout the test period.
A standard laboratory rabbit diet and tap water were provided ad libitum.
Test system
- Type of coverage:
- not specified
- Preparation of test site:
- clipped
- Remarks:
- Electric clippers were used to remove the hair from the back and flanks of the animal.
- Vehicle:
- water
- Remarks:
- 0.5 g of test material was moistened with 0.5 g of water.
- Controls:
- no
- Amount / concentration applied:
- Just prior to application, the test substance was moistened with water in a ratio of 1: 1 (w/w) , to ensure good contact with the skin of the rabbits.
- Duration of treatment / exposure:
- Exposure period: 4 hrs
- Observation period:
- Initial skin reaction was observed after 1 hr. Further readings were made after 24, 48 and 72 hours, and after 8,14 and 23 days.
- Number of animals:
- 1 rabbit.
- Details on study design:
- The study was started with one rabbit. Depending on the severity of the skin effects observed in this animal it would be decided to conduct a full study with three rabbits or to use no more than one rabbit. After an acclimatization period of six days, i.e. one day prior to the start of the experiment, the hair was removed from the back and flanks of the animal using electric clippers in a way as to avoid abrasions.
An amount of 0. 5 g test substance moistened with 0. 5 g water was brought on a small area of intact skin under a plastic cup with a diameter of about 1 inch. The cup was fixed to the application site by means of adhesive tape and the entire trunk of the rabbit was wrapped with an impervious material to maintain the cup in position and to retard evaporation of volatile substances.
After an exposure period of 4 hours the cup and the test material applied were removed and one hour later, the resulting skin reactions were evaluated by the method of Draize et al. (J. Pharmacol. Exp. Ther. 82 (1944) 377-390).
One hour after treatment, the resulting skin effects were of a severe degree. Therefore, it was decided not to continue the study with another two rabbits.
Further readings were made after 24, 48 and 72 hours, and after 8,14 and 23 days.

Any other information on results incl. tables
Skin irritation scores recorded at 1-72 hours after removal of the test substance are shown in table 1.
At 1 hour, and at 24, 48 and 72 hours after removal of the test substance, skin effects such as erythema could not be observed because of the ischemic necrosis or incrustation which was present on the entire site of the application.
The following skin effects were observed up to 72 hours after removal:
slight or severe oedema
- moderate to severe or severe ischemia
- slight haemorrhages
- moderate to severe incrustation
After 8 days, severe incrustation was observed.
After 14 days, slight incrustation and scar tissue formation were observed.
After 21 days, scar tissue was still observed.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1C (corrosive) based on GHS criteria
- Conclusions:
- On the basis of the results obtained it is concluded that, according to the EEC-standards (as published in the Official Journal of the European Communities, L 257, Volume 26, 16 September 1983), m-chloroperoxybenzoic acid is irritating and corrosive to skin.
- Executive summary:
1. A sample of m-chloroperoxybenzoic acid was examined for acute dermal irritating/corrosive properties in an experiment with one albino rabbit. The test substance was moistened with water, in a ratio of 1:1, before it was applied to the skin. The dermal exposure period was 4 hours.
2. The dermal effects and skin reactions observed consisted of severe oedema, severe ischemic necrosis, slight haemorrhages, severe incrustation and scar tissue formation. Because of the severe degree of the effects observed it was decided to use only one rabbit instead of three.
3. On the basis of the results obtained it was concluded that, according to the EEC-standards, m-chloroperoxybenzoic acid is irritating and corrosive to skin.
