- PROCEDURE:
Approximately 24 hours before the test item application, each rabbit was clipped free of hair from the dorso-lumbar region using electric clippers exposing an area of skin approximately 100 mm x 100 mm.
Approximately 0.5 ml of the test item was applied under a 2-ply 25 mm x 25 mm porous gauze pad to one intact skin site on each animal. Each treatment site was covered with "Elastoplast" elastic adhesive dressing for four hours. The animals were not restrained during the exposure period and were returned to their cages immediately after treatment.
At the end of the exposure period the semi occlusive dressing and gauze were removed from each animal and the treatment site washed with warm water to remove any residual test item. The treated area was blotted dry with absorbent paper.
Examination of the treated skin was made approximately 1 hour following removal of the dressings and 24, 48 and 72 hours after exposure. Additional observations were made for all animals on Days 5 through to 14. Local dermal irritation was assessed using the numerical system, see any other information on materials and methods
Any other skin reactions if present, were also recorded. - Irritation parameter:

- Irritant / corrosive response data:
- Please see attached background information for individual skin reactions.
Severe erythema with slight to moderate oedema and necrotic patches were seen in all three animals. The necrotic patches began sloughing off in two animals on Day 11 revealing new skin underneath. Blanching of the skin and desquamation (characterised by dryness of the skin) were observed in all animals. Reactions gradually ameliorated however very slight to well defined erythema with or without very slight oedema was still evident in all animals at study termination on Day 14. - Other effects:
- There were no other signs of toxicity or ill health.
- Interpretation of results:
- Category 1C (corrosive) based on GHS criteria
- Conclusions:
- A single semi occlusive application of the test substance to intact rabbit skin for four hours elicited severe dermal irritation with necrotic patches.
The test item meets the criteria for classification according to the Classification, Labelling and Packaging Regulation (CLP) or the Globally Harmonised Classification System. - Executive summary:
Introduction.
The study was performed to assess the irritancy potential of the test item to the skin of the New Zealand White rabbit. The method was designed to be compatible with the following:
- OECD Guidelines for the Testing of Chemicals No. 404 “Acute Dermal Irritation/Corrosion” (adopted 17 July 1992)
- Method B4 Acute Toxicity (Skin Irritation) of Commission Directive 92/69/EEC
- EPA Health Effects Test Guidelines OPPTS 870.2500 Acute Dermal Irritation EPA 712 -C-98 -196 (August 1998)
Results.
A single 4-hour, semi-occluded application of the test item to the intact skin of three rabbits for four hours elicited severe dermal irritation with necrotic patches.
Conclusion.
The test item is classified as corrosive according to the Classification, Labelling and Packaging Regulation (CLP) or the Globally Harmonised Classification System.

- Executive summary:
Introduction
A primary dermal irritation study was performed to evaluate the irritancy potential of the test item to the skin of the New Zealand White rabbit.
Method
The test item was applied to 1 intact test site on each of 6 rabbits and covered with impervious bandages for 4 hours. After which the test sites were wiped clean of residual test material and evaluated for erythema, edema and other lesions at 30 - 60 minutes, at 24, 48 and 72 hours and on days 4 to 7.
Results
Well defined to moderate erythema and slight to moderate edema was observed for all animals. Desquamation was noted at the test sites of 2 animals at 72 hours, 4 animals at Day 4 and 5 and for all animals on Days 6 and 7. Dermal reactions decreased in severity from 24 hours to day 7.
No mortalities occurred during the study and all animals were free of overt signs of toxicity.

- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS
- Source: Young adult male and female albino New Zealand rabbits obtained from Clerco Research Farm, Cincinnati, OH, USA
- Housing: The animals were housed individually in stainless steel cages with wire mesh floors.
- Diet (e.g. ad libitum): Purina Certified Rabbit Chow 5322 was fed throughout the study.
- Water (e.g. ad libitum): Free access to filtered tap water was provided through an automatic watering system.
- Acclimation period: 7 days.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 67 ± 5 F
- Humidity (%): 30 - 70%
- Ventilation: The animal room was well ventilated and air conditioned
- Photoperiod (hrs dark / hrs light): lighting was controlled by automatic timers to give twelve hours continuous light (06:00 to 18:00) and twelve hours darkness. - Vehicle:
- unchanged (no vehicle)
- Controls:
- other:
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied : 0.1ml
- Observation period (in vivo):
- 1hr, 24, 48 and 72 hours and 7 days after instillation of the test item
- Number of animals or in vitro replicates:
- 3 males and 3 females
- Details on study design:
- REMOVAL OF TEST SUBSTANCE
- Washing (if done): Eyes were not washed after treatment
SCORING SYSTEM: Draize
TOOL USED TO ASSESS SCORE: A pocket flashlight without magnification was used at all evaluation intervals. A 2% sodium Fluorescein solution in deionised water was used at all evaluations except for those done at 1 hour after instillation. - Irritation parameter:

Additional information
Two in vivo dermal irritation studies and one in vivo eye study are available. The most recent in vivo dermal irritation study was considered the most reliable and was used for classification. This study showed the substance to be corrosive. The substance can therefore be considered to lead to serious eye damage.
Justification for classification or non-classification
According to the criteria for classification and labelling of substances and mixtures (Regulation (EC) No. 1272/2008), the substance qualifies for classification as Skin Corrosive 1C, H314: Eye Damage 1, H318.
