Breeder: Grimaud freres selection S.A.S., La Corbiere, Roussay, France.
Number: three animals were used, as recommended by the international guidelines.
Age/weight: on the day of treatment, the animals were 2 to 4 months old and had a mean body
weight istandard deviation of2.6 i0.1 kg.
Acclimation: at least 5 days before the beginning ofthe study.
Identication: individual metal ear tag.
The conditions in the animal room were set as follows:
. temperature: 18 ± 3° C
. relative humidity: 30 to 70%
. light/dark cycle: 12 h/12 h
. ventilation: approximately 12 cycles/hour ofltered, non-recycled air.
The temperature and relative humidity were under continuous control and recording. The records were checked daily and led. In addition to these daily checks, the housing conditions and corresponding instrumentation and equipment were veried and calibrated at regular intervals.
The animals were housed individually in Pajon cages (50 cm x 57 cm x 75 cm).
Each cage was equipped with a food container and a water bottle.
During the study, the animals had free access to 110C pelleted diet (SAFE, Villemoisson, Epinay-sur-Orge, France). Food was analyzed regularly by the supplier for composition and contaminant levels. Drinking water ltered by a FG Millipore membrane (0.22 micron) was provided ad libitum. Bacteriological and chemical analyses ofwater are performed regularly by external laboratories. These analyses include the detection of possible contaminants (pesticides, heavy metals and nitrosamines). No contaminants were known to have been present in the diet or drinking water at levels which may be expected to have interfered with or prejudiced the outcome ofthe study. - Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The untreated skin served as control.
- Amount / concentration applied:
- Doses of 0.5 mL of the undiluted test item were placed on a dry gauze, which was then applied to an area of approximately 6 cm2 of the anterior left ank (application for 3 minutes), the anterior right ank (application for l hour) or the posterior right ank (application for 4 hours) of the animals. The gauze pad was held in contact with the skin by means of an adhesive hypoallergenic aerated semi-occlusive dressing and a restraining bandage.
The untreated skin served as control. No residual test item was observed on removal ofthe dressing. - Duration of treatment / exposure:
- 3 minutes on anterior left ank, 1 hour on anterior right ank and 4 hours on posterior right ank
- Observation period:
- The skin was examined approximately 1 hour, 24, 48 and 72 hours after removal of the dressing. Since there were persistent irritation reactions (dryness) at 72 hours in animal No. 697 (anterior left ank), the observation period was extended up to their complete reversibility (Le. day 14).
- Number of animals:
- 3 male animlas
- Details on study design:
- Criteria for irritation
A substance or a preparation is considered to be irritating to the skin if, when it is applied to healthy intact animal skin for up to 4 hours, significant inammation is caused and which persists for 24 hours or more after the end of the exposure period.
Criteria for corrosion
A substance or a preparation is considered to be corrosive if, when it is applied to healthy intact animal skin, it produces full thickness destruction of skin tissue on at least one animal during the test for skin irritation, or if the result can be predicted (for example: from strongly acid or alkaline reactions). - Irritation parameter:

- Executive summary:
In this study 3 animals were exposed topically to 2-ethylhexyl salicylate over a period of 3 minutes, 1 hour and 4 hours respectively. One hour following removal of the patches slight erythrema were noted at the sites exposed to 3 minutes and 1 hour wereas the erythema were well-defined (grade 2) where exposed for 4 hours. However, all erythema fully reversed within 24 hours and onyl in one animal following 48 hours. No Edema were recorded in any of the animals at any time. Dryness of skin was noted in one animal following 3 minutes exposure but this fully reversed within 14 days. Thus, the test item was considered non-irritant following the CLP (Regualtion EC No 1272/2008) classification system

Additional information
Skin irritation:
In a GLP compliant OECD404 guideline study with rabbits using 99.8% pure 2-ethylhexylsalicylate applied over 3 minutes, 1 hour and 4 hours respectively well-defined erythema were noted directly following removal of the test item but the skin fully recovered within 24 hours (in one animal within 48 hours). No edema were observed at any time. In a second study (Test No. 1989132) the potential primary skin irritation of test article at different concentrations was investigated. Six female rabbits were administered dermally at 4 different concentrations of 100%, 25%, 5% and 1% of test article and a vehicle control on each animal. The mean scores for erythema and edema at 100% test concentration were 2.5 and 1.7, respectively, and not fully reversed within 14-day observation period. The mean scores for erythema and edema at 25% test concentration were 1.7 and 0.9, respectively. The mean score for erythema at 5% test concentration was 0.1, as well as 1% test concentration, and fully reserved within 72 hours. On day 7, edema, erythema and a layer of scales were observed on the test sites of four of the rabbits, treated with 100% test concentration. Scales were seen on the test sites of all the rabbits, treated with 25% test concentration, along with erythema on two rabbits. On day 14, scattered to thick layer of yellow scales were seen on the test sites of five of the rabbits, treated with 100% test concentrations. Scattered scales were seen on the test sites of two of the rabbits, treated with 25% test concentration. However, as the purity of test material was not recorded in the test report and the results do contradict the first study when comparing results for neat substance, the effects seen in this second study may have been attributable to impurities present in the test item and thus this study was disregarded and not used for classification and risk assessment.
Therefore, pure test article is considered to be not a skin irritant under the condition of an OECD404 test protocol according to CLP (Regulation EC No 1272/2008).
Eye irritation:
Two eye irritation studies are available, one testing undiluted material and another supporting study using 50% solution of test item. Under the conditions of the first study using undiluted material (Report No 31722 TAL) , the test item 2-ethylhexyl salicylate (SALICYLATE D'OCTYLE) was slightly irritant when administered by ocular route to rabbits, when 0.1 ml of neat material was applied to rabbit eyes. The criteria for classification according to CLP (regulation EC No 1272/2008) were not met. Another study (Test No. 1989133) was conducted to investigate the primary eye irritant effect of test article in a 50% solution. About 0.1 ml of the diluted test article was placed in the left eye of each rabbit by gently pulling the lower lid away from the eyeball to form a cup into which the test substance was dropped. The eyes were examined and the grade of ocular reaction was recorded 1 hour later. 24 hour later an examination was performed before and after installation of oculoguttao flouresceini. After the examined the eyes were rinsed with 20 ml of a 0.9% sodium chloride solution. The eyes were also examined 48 and 72 hours after the treatment. Slight reactions of conjunctiva (redness) were seen in one rabbit at the 1- and 24-hour reading. No reactions of the conjunctiva, iris or cornea were observed in any of the rabbits at the 48- and 72-hour readings.
It is concluded that the test article in neat form and as 50% solution did not cause positive eye response in rabbits.
Justification for selection of skin irritation / corrosion endpoint:
OECD TG and GLP compliant study
Justification for selection of eye irritation endpoint:
OECD TG and GLP compliant study, Substance was tested undiluted whereas supportive study only 50% conc. was applied
Justification for classification or non-classification
In an OECD404 guideline study according to GLP the pure test substance (99.8% purity) was found to be non-irritant according to the criteria in CLP (Regulation EC No 1272/2008) and only slight, respectively well-defined, erythema were observed directly after removal of the patches which full reversed within 24 respectively 48 hours. In another primary skin irritation/corrosion test in 6 rabbits with 2-ethylhexyl salicylate, the individual mean of scores 1, 2 and 3 days after treatment were 3.0, 2.0, 1.67, 2.33, 3.0, 3.0 for edema and 2.33, 1.0, 1.3, 1.67, 1.67, 2.33 for erythema. However, in the study report no purity was provided and it cannot be excluded that effects seen were caused by impurities. Thus this study was disregarded for classification and classification is based on the first study with 99.8% purity. Therefore, 2-ethylhexyl salicylate is not to be classified for skin irritation/corrosion according to the criteria laid down in the EU Dangerous Substances Directive (67/548/) and according to the criteria of the EU Classification Labelling and Packaging Regulation (1272/2008/EC).
In guideline-compliant acute eye irritation/corrosion test in rabbits, neat and 50% 2-ethylhexyl salicylate caused no corneal opacity, iridial irritation and no irritation of the conjunctivae consisting chemosis or discharge at levels triggering classification. Therefore, 2-ethylhexyl salicylate does not have to be classified according to the criteria laid down in the EU Dangerous Substances Directive (67/548/) and according to the criteria of the EU Classification Labelling and Packaging Regulation (1272/2008/EC).
No conclusion on classification and labeling regarding respiratory tract irritation can be derived due to lack of data.
