Details on study design:
TEST SITE
- Area of exposure: 2.5 cm x 2.5 cm (area of gauze patch used)
- Type of wrap if used: gauze patch secured in position with adhesive strapping

REMOVAL OF TEST SUBSTANCE
- Washing: gentle swabbing with cotton wool soaked in ether
- Time after start of exposure: 4 hours

SCORING SYSTEM:
Approximately 1, 24, 48 and 72 hour(s) after patch removal, the test sites were examined and scored acording to the scale of Draize. The scores for erythema and oedema at the 24 and 72 hour readings were totalled for the 3 test rabbits (12 values). This total was divided by 6 to give the Primary Irritation Index of the test item. This index was used to classify the skin irritation according to the scheme shown under "Any other information on materials and methods incl. tables".

Well defined erythema accompanied by minimal oedema, with the reactions extending beyond the site of application was noted in 3/3 rabbits at the 1 -hour reading and in 2/3 rabbits at subsequent 24, 48 and 72 -hour observations. The skin irritation had become less marked in one rabbit by the 24 -hour reading when barely perceptible erythema was seen in this animal. In addition, desquamation was noted in 2/3 rabbits at this stage. Similar levels of reaction persisted at subsequent 48 and 72 -hour readings. A reduction in the level of reaction was seen at day 7 when barely perceptible erythema accompanied by desquamation, with the reactions extending beyond the site of application was apparent in the remaining animal at this stage.

Interpretation of results:
moderately irritating
Remarks:
Migrated information
Executive summary:

In a primary dermal irritation study (Jones & Collier, 1985), 3 young adult New Zealand White rabbits were dermally exposed to 0.5 mL of ZD 8 Gewaschen for 4 hours. Animals then were observed for 7 days. Irritation was scored by the method of Draize (1959). The primary irritation index was used for classification of irritancy.

In this study, ZD 8 gewaschen was a moderate irritant based on well defined erythema accompanied by minimal oedema noted and scored in all rabbits.

No evidence of corneal damage was noted throughout the 72-hour study period. Iridial inflammation was apparent in 2/3 rabbits at the 1-hour reading only. Slight conjunctivitis identified by redness (grade 2) and swelling (grades 1-2) was noted in 3/3 rabbits at the 1-hour reading. The reactions had resolved completely by the 24-hour (1/3 rabbits) or the 48-hour observation (2/3 rabbits). In addition, 0/3 rabbits showed evidence of positive ocular irritation.

Executive summary:

In a primary eye irritation study (Jones & Collier, 1985), 0.1 mL of undiluted ZD 8 Gewaschen was instilled into the conjunctival sac of the right eye of young adult New Zealand White rabbits. Animals then were observed for 72 hours following treatment. Irritation was scored by the method of Draize (1959) and the test item was classified for its ocular irritation potential according to Kay & Calandra (1962, modified). The treatment resulted in a maximum mean score of 10 and the test item was classified as a minimal irritant (class 3 on a scale of 1 to 8).

In this study, ZD 8 Gewaschen was a minimal irritant to the rabbit eye.

Additional information

In a primary skin irritation study (Jones & Collier, 1985), 3 young adult New Zealand White rabbits were dermally exposed to 0.5 mL of ZD 8 Gewaschen (identical to 1-Hexanol, 2-ethyl-, manuf. of, by-products from, distn. Residues) for 4 hours. Animals then were observed for 7 days. Irritation was scored by the method of Draize (1959). The primary irritation index was used for classification of irritancy. ZD 8 gewaschen was a moderate irritant based on well defined erythema accompanied by minimal oedema noted and scored in all rabbits. The mean erythema score (24, 28 and 72 hour reading) was 1 for animal #1, and 2 for animal #2 and #3. The mean oedema score (24, 48 and 72 hour reading) was 0, 1 and 0.67 for animal #1, #2 and #3, respectively. Mild signs of irritation were still present at the end of the observation period.

In a primary eye irritation study (Jones & Collier, 1985), 0.1 mL of undiluted ZD 8 Gewaschen was instilled into the conjunctival sac of the right eye of young adult New Zealand White rabbits. Animals then were observed for 72 hours following treatment. Irritation was scored by the method of Draize (1959) and the test item was classified for its ocular irritation potential according to Kay & Calandra (1962, modified). In this study, ZD 8 Gewaschen was a minimal irritant to the rabbit eye.


Effects on skin irritation/corrosion: irritating

Effects on eye irritation: slightly irritating

Justification for classification or non-classification

Based on the results of the skin and eye irritation key toxicity studies. 1-Hexanol, 2-ethyl-, manuf. of, by-products from, distn. Residues is classified and labelled for skin irritation / corrosion according to Directive 67/548/EEC as R38, irritating to skin and according to Regulation 1272/2008/EC as Cat. 2, H315, causes skin irritation.
