- The body weight was recorded at start and on day 3 of the test.
TEST SITE
- Area of exposure: An area of at least 36 cm2 was shaved on both flanks of the animals approximately 24 hours before treatment.
- Type of wrap: A gauze patch (20 cm2) was applied to the flank. A control gauze patch was applied to the contralateral flank. Both gauze patches were moistened before application with distilled water containing 0.5 % carboxymethylcellulose and 0.1 % polysorbate 80. The patches were loosely covered with an aluminium foil (36 cm2) and held in place by an adhesive tape.
REMOVAL OF TEST SUBSTANCE

Approximately 1, 24, 48 and 72 hours after the end of exposure
SCORING SYSTEM:
- Method of calculation: following the OECD TG 404 system. For criteria, see 'Any other information on materials and methods incl. tables'. - Irritation parameter:
- erythema score
- Basis:
- animal: #1, #2, #3
- Time point:
- 24/48/72 h
- Score:
- 0
- Max. score:
- 4
- Remarks on result:
- no indication of irritation
- Irritation parameter:
- edema score
- Basis:
- animal: #1, #2, #3
- Time point:
- 24/48/72 h
- Score:
- 0
- Max. score:
- 4
- Remarks on result:
- no indication of irritation
- Irritant / corrosive response data:
- Two animals exhibited slight erythema reactions (score 1) one hour after treatment with test substance. Scores of erythema and oedema for the recordings 24 to 72 hours in all 3 animals were zero (considered to be non-irritating).
- Other effects:
- BODY WEIGHT
The body weights of all rabbits were considered to be within the normal range of variability.
DURATION OF THE IN-LIFE PHASE
Because no reactions were observed at 24 hours to 72 hours after removing the bandages, the test was ended after the 72 hours evaluation. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- Because the mean values of the recordings 24 to 72 hours after application were scored zero, the test substance can be classified as non-irritant.
- Executive summary:
The primary skin irritation potential of the test substance was investigated according to the GLP compliant OECD TG 404. An amount of 0.5 g unchanged test material was applied under occlusive conditions for 4 hours to the clipped backs of 3 females albino New Zealand White rabbits (KFM-NZW), using a gauze patch of 20 cm2. A control gauze patch was applied to the contralateral flank. Both gauze patches were moistened before application with distilled water containing 0.5 % carboxymethylcellulose and 0.1 % polysorbate 80. The patches were loosely covered with an aluminium foil (36 cm2) and held in place for 4 hours by an adhesive tape. Scoring was performed at 1, 4, 24, 48 and 72 hours and after 3 days of application following OECD TG 404.
Two animals exhibited slight erythema reactions (score 1) one hour after treatment with test substance. Since no reactions were observed at 24 hours to 72 hours after removing the bandages, the test was terminated after the 72 hours evaluation. Scores of erythema and oedema for the recordings 24 to 72 hours in all 3 animals were zero. Under the conditions of this study, the test substance was considered not to be irritating to the skin of rabbits.

- INSTILLATION
The test substance was placed into the conjunctival sac of the left eye of each animal, after gently pulling away the lower lid from the eyeball. The lids were then held together for about one second in order to prevent loss of the test material. The right eye remained untreated and served as a control.
OCULAR SCORING
The ocular reactions were evaluated 1, 24, 48, and 72 hours after the instillation of the test substance according to the OECD scoring system (see Table 1 at ‘Any other information on methods and materials incl. tables’). A slit-lamp was used to facilitate the evaluation.
The irritant/corrosive potency of test substance was classified according to the EC Commission Directive No. 83/467, 1983. Ocular lesions which occur within 72 hours after exposure and which persist for at least 24 hours and correspond to the following values determined on the rabbit according to the eye irritation method:
- The mean value of the scores for each type of lesion, calculated over all the animals tested, is one of the following:
(1) cornea opacity two or more
(2) iris lesion one or more
(3) redness of conjunctivae 2.5 or more
(4) oedema of conjunctivae
(5) (chemosis) two or more
- or, in the case where the Annex V test has been completed using three animals, either cornea opacity, iris lesion, redness of conjunctivae or oedema of conjunctivae (chemosis) equivalent to a mean value such as is quoted above, but calculated for each animal separately, has been observed in two or more animals.
In both cases all scores at each of the reading times (24, 48, and 72 hours) and for an effect should be used in calculating the respective means values.

Skin irritation in rabbits, Schneider 1988
The primary skin irritation potential of the test substance was investigated according to the GLP compliant OECD TG 404. An amount of 0.5 g unchanged test material was applied under occlusive conditions for 4 hours to the clipped backs of 3 females albino New Zealand White rabbits (KFM-NZW), using a gauze patch of 20 cm2. A control gauze patch was applied to the contralateral flank. Both gauze patches were moistened before application with distilled water containing 0.5 % carboxymethylcellulose and 0.1 % polysorbate 80. The patches were loosely covered with an aluminium foil (36 cm2) and held in place for 4 hours by an adhesive tape. Scoring was performed at 1, 4, 24, 48 and 72 hours and after 3 days of application following OECD TG 404.
Two animals exhibited slight erythema reactions (score 1) one hour after treatment with test substance. Since no reactions were observed at 24 hours to 72 hours after removing the bandages, the test was terminated after the 72 hours evaluation. Scores of erythema and oedema for the recordings 24 to 72 hours in all 3 animals were zero. Under the conditions of this study, the test substance was considered not to be irritating to the skin of rabbits.
