Room no: 106/ RCC Ltd, Füllinsdorf
Conditions: Standard Laboratory Conditions, Air-conditioned with target ranges for room temperature 17 - 23 °C, relative humidity 30-70 % and approximately 10-15 air changes per hour. Room temperature and humidity were monitored continuously and values outside of these ranges may have occasionally occurred, usually following room cleaning. These transient variations are considered not to have any influence on the study and, therefore, these data are not reported but are retained at RCC. The animals were provided with an automatically controlled light cycle of 12 hours light and 12 hours dark. Music was played during the daytime light period.
Accommodation: Individually in stainless steel cages equipped with feed hoppers and drinking water bowls. Wood blocks (RCC Ltd, Füllinsdorf) and haysticks 4646 (batch no. 0206, Provimi Kliba AG) were provided for gnawing.
Diet: Pelleted standard Provimi Kliba 3418 rabbit maintenance diet ad libitum (batch no. 64/02) provided by Provimi Kliba AG, CH-4303 Kaiseraugst. Results of analysis for contaminants are archived at RCC Ltd, Itingen.

- 500 mg
- Duration of treatment / exposure:
- 4 h
- Observation period:
- 10 days
- Number of animals:

- Details on study design:
- TEST ITEM PREPARATION: 0.5 g (per animal) of FAT 40810/A was weighed as delivered by the sponsor and then moistened with approximately 0.1 mL of purified water before application. The pH of the test item was measured before the study initiation date. A formulation of 1 % in water was prepared. The pH was found to be 5.19. According to Directive 92/69 EEC, B.4. and OECD Guidelines 404, a test item needs not to be tested if the pH-value is less than 2 or greater than 11.5, owing to its predictable corrosive properties.
TREATMENT: Four days before treatment, one flank was clipped with an electric clipper, exposing an area of approximately 100 sq.cm (10 cm x 10 cm). The skin of the animals was examined one day before treatment, and regrown fur of all animals was again clipped. Animals with overt signs of skin injury or marked irritation which may have interfered with the interpretation of the results were not used in the test. On the day of treatment, 0.5 g of FAT 40810/A was placed on a surgical gauze patch (ca. 4 cm x 4 cm). This gauze patch was applied to the intact skin of the clipped area. The patch was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape. The duration of treatment was 4 hours. Then the dressing was removed and the skin was flushed with lukewarm tap water to clean the application site so that any reactions (erythema) were clearly visible at that time.
OBSERVATIONS: Viability/Mortality: Daily from delivery of the animals to the termination of test. Clinical signs: Daily from delivery of the animals to the termination of test. Body weights: At start of acclimatization, on the day of application and at termination of observation.
IRRITATION SCORES: The skin reaction was assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEC, July 31, 1992 approximately 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after the removal of the dressing, gauze patch and test item. To allow further examination of the test site animal No. 63 was re-clipped on completion of the 48-hour examination.

The test item caused red staining of the treated skin. This
effect was reversible and was no longer evident 10 days
after treatment.
MORTALITY/CLINICAL SIGNS: No mortality and no clinical signs observed. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT40810/A is non-irritating to skin.
- Executive summary:
The primary skin irritation potential of FAT 40810/A was investigated by topical semi occlusive application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. This study was conducted in accordance with OECD test guideline 404 in a GLP certified laboratory. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours, as well as 7 and 10 days after removal of the dressing. The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.
The application of FAT 40'810/A to the skin resulted in no signs of irritation. The test item caused red staining of the treated skin. This effect was reversible and was no longer evident 10 days after treatment, the end of the observation period for all animals. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals.
Thus, the test item did not induce significant or irreversible damage to the skin. Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 06, 2001), FAT 40'810/A is considered to be "not irritating" to rabbit skin.

- Number of animals or in vitro replicates:
- 3
- Details on study design:
- TEST ITEM PREPARATION: 0.1 g (per animal) of FAT 40810/A was weighed and applied undiluted as it was delivered by the sponsor. The pH of the test item was measured for a previous study (RCC Study number 847220, skin irritation with FAT 40810/A in rabbits) and was found to be 5.19. According to Directive 92/69 EEC, B.5. and OECD Guidelines 405, a test item needs not to be tested if the pH-value is less than 2 or greater than 11.5, owing to its predictable corrosive properties.
TREATMENT: The eyes of the animals were examined one day prior to test item administration. Animals with overt signs of ocular injury or irritation which may have interfered with the interpretation of the results were not used in the test. On the day of treatment, 0.1 g of FAT 40810/A was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of test item. The right eye remained untreated and served as the reference control. The treated eyes were not rinsed after instillation.
OBSERVATIONS:
Viability/Mortality Daily from acclimatization of the animals to the termination of test.
Clinical signs: Daily from acclimatization of the animals to the termination of test.
Body weights: At start of acclimatization, on the day of application and at termination of observation.
IRRITATION SCORES: The ocular reaction was assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEC, July 31, 1992 at approximately 1, 24, 48 and 72 hours, as well as 7, 10, 14, 17 and 21 days after application. When present, corrosion and/or staining of sclera and cornea by the test item were recorded and reported. Eye examinations were made with a Varta Cliptrix diagnostic-lamp (Roth AG, CH-4153 Reinach/Switzerland).

- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Due to discoloration of the eyes by FAT 40810/A the substance is considered causing irreversible effects to eyes (CLP Category 1, H318)
- Executive summary:
The primary eye irritation potential of FAT 40810/A was investigated according to OECD test guideline no. 405. The test item was applied by instillation of 0.1 g into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours, as well as 7, 10, 14, 17 and 21 days after test item application. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctivae were 0.33, 0.67 and 0.33 for reddening and 0.0, 0.0 and 0.0 for chemosis, respectively. The instillation of FAT 40810/A into the eye resulted in mild, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae and chemosis. These effects were reversible and were no longer evident 72 hours after treatment. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. Red staining of the treated eyes by the test item was observed in all animals throughout 10 days after treatment and persisted in two animals up to 21 days after treatment, the end of the observation time for all animals. No other clinical signs of substance related effects were observed. Due to discoloration of the eyes by FAT 40810/A the substance is considered causing irreversible effects to eyes (CLP Category 1, H318).
Reference
Comments: All irritant effects (slight reddening of the conjunctivae and the sclerea, slight swelling) were fully reversible within 1 to 2 days. However, due to the irreversible coloration after 21 days, the substance needs to be classified as irritant and labelled with R41.
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irreversible damage)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Additional information
FAT 40810/A was investigated for skin and eye irritation/corrosion in vivo using rabbits (OECD 404 and 405). Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 06, 2001), FAT 40810/A is considered to be "not irritating" to rabbit skin, as no signs of skin irritation were observed throughout the entire study. Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 06, 2001), with the exception of the red staining, which was still evident at termination, FAT 40810/A is considered to be "not irritating" to the rabbit eye. However, due to the irreversible coloration after 21 days, the substance needs to be classified as irritant (Xi, R41 according to DSD) respectively as causing irreversible damage to eyes according to CLP (Category 1, H318). Data for respiratory irritation are not available.
Effects on eye irritation: irritating
Justification for classification or non-classification
Based on two in vivo studies using rabbits, investigating skin and eye irritation potential, FAT40810/A is not classifiable for skin irritation corrosion according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC). Although no significant eye irritation was observed, the substance caused staining of the eyes which did not fully revers during the observation period and thus FAT40810/A is classified as causing irreversible effects to eyes according to CLP (i.e. Category 1, H318) and accordingly as irritant (Xi), R41 according to DSD. Data for respiratory irritation is not available.
