Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Healthy New Zealand White rabbits (Porton strain) aged ·13 - 17 weeks with average body weights of 3.04 kg. (males) and 2.46 kg (females), bred on the premises and maintained under a semi-barrier system. Six rabbits (3 of each sex) were acclimatized in the test area for one week prior to the start of the trial. The rabbits were caged singly in an experimental room maintained at a temperature of 20degrees C (+/-1°) and a relative humidity of 50-70%. Animals were exposed to artificial light for 10 hours daily from 08.00 - 18.00 hours. A commercial irradiated diet (Styles-Oxoid) was fed ad lib. Sterile filtered water was available at all times.
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- other: shaved with one area intact and one area abraded
- Vehicle:
- unchanged (no vehicle)
- Controls:
- no
- Amount / concentration applied:
- 0.5 ml
- Duration of treatment / exposure:
- 24 hours
- Observation period:
- 14 days
- Number of animals:
- 6
- Details on study design:
- Twenty-four hours prior to the dermal application, the backs of the rabhits were shaved over an area consisting of at least 10% of the total body surface. Two test sites lateral to the mid line "of the back were used on each rabbit. lmmediately before the application of the test compound, the right hand site was abraded with the point of a sterile hypodermic needle. The abrasions were sufficiently deep to penetrate the stratum corneum but not to damage the dermis. The left hand site remained intact.
0.5ml of the test compound was applied to each test site on a 2.5cm square gauze pad. These were covered with aluminium foil secured with adhesive tape. The test sites were then covered by a 6 inch wide self adhesive bandage in order to retain the test substance in close contace with the skin.
After 24 hours the dressing was removed and· the intact and abraded application sites were assessed for oedema and erythema. A further assessment was made at 72 hours and for any further period considered necessary up to 14 .

- Irritant / corrosive response data:
- 24 hours: Well defined erythema was present on 2/6 intact sites and all the remaining sites were showing evidence of necrosis. Moderate to severe oedema was also seen on all sites.
72 hours: Eschar formation involving dermal layers was ssen on 4/6 intact and 6/6 abraded sites. The remaining 2 intact sites were showing slight to well defined erythema. Slight to severe oedema was present on all sites.
6 days: Eschar formation was seen on 4/6 intact and 6/6 abraded sites with the remaining 2 intact sites showing well defined-erythema. Slight ·to moderate oedema was also present on all sites. 3 rabbits were sacrificed at this time.
10 days: The 3 remaining rabbits showed eschar formation and very slight to slight oedema on all sites.
14 days: (Termination of study) Eschar formation was still present on all sites and very slight to slight oedema on 2/3 intact and 3/3 abraded sites.
"If sufficient time had been allowed to elapse all sites would have eventually healed with some residual scarring.
Generally, there was very little difference seen in the reactions between intact and abraded sites.
The primary irritation score was 7.2.
Applicant's summary and conclusion
- Interpretation of results:
- corrosive
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- The test material is corrosive to skin in the albino rabbit.
- Executive summary:
Healthy New Zealand White rabbits (Porton strain) were tested for skin irritation with the test material. Reactions of 4+ (according to Draize scoring) for erythema and oedema was seem on abraded and intact sites on all animals at 72 hours and was still seen at 14 days on 3/6 animals. The test material is considered corrosive to skin in the albino rabbit.
