The objective of this OECD 423 study was to assess the adverse effects which can follow within a short period of time after a single oral gavage administration of EC 903-162-9 to rats. The test item was administered to 2 groups, each comprising 3 female Sprague-Dawley rats, at a dose level of 2000 mg/kg. The animals were observed for 14 days after the day of dosing. The test item was formulated in corn oil. The dose volume, 4 mL/kg, was based on the concentration of the test formulation (500 mg/mL). Individual doses were based on each individual animal’s body weight on the day of dosing. The following parameters and end points were evaluated in this study: clinical signs, body weights, body weight changes, and gross necropsy findings.
All animals survived treatment and no adverse clinical signs or macroscopic abnormalities were recorded in any animal. Body weight gains were considered to be acceptable for rats of this age and strain. Under the conditions of the study the median lethal dose level (LD50) of EC 903-162-9 in Sprague-Dawley rats were considered to not exceed 2000 mg/kg.

- Executive summary:
The objective of this OECD 402 study was to assess the adverse effects which can follow within a short period of time after a single dermal administration of EC-903-161-3 to rats.
The test item was administered to a single group of 5 male and 5 female Sprague-Dawley rats. The study design was as follows:

The selected dose level for this study was 2000 mg/kg. The Sponsor stated that the test item density was 1.185 kg/L. Because the density was not used to calculate the administered dose volumes, the actual dose level was 2370 mg/kg.
The test item was administered, as supplied, onto the dorsal trunk under a gauze patch which was covered with semi-occlusive tape, then secured with occlusive tape (iethe site was fully occluded). The dressings remained in place for 24 h. The dose was calculated on the basis of the body weights of the animals on the day of dosing. Animals were observed for signs of reaction to treatment a minimum of 5 times on the day of dosing. Thereafter animals were observed once daily from Day 2 until the end of the observation period on Day 15. Body weights were recorded weekly and all animals were subjected to a necropsy examination.
The following parameters and end points were evaluated in this study: clinical signs, body weights, body weight changes, and gross necropsy findings.
There were no unscheduled deaths during the observation period.
There were no systemic signs of toxicity noted in any animal at any observation timepoint and local findings at the dosing site were restricted to test item residues at the test site, which was seen in all animals on Day 2 only.
Body weight gain was considered to be acceptable for rats of this age and strain. No abnormal findings were noted at necropsy.
Under the conditions of the study, the median lethal dermal dosage (LD50) for EC-903-161-3 in Sprague-Dawley rats was estimated to be greater than 2370 mg/kg.The study is being used as read across from EC 903-161-3 to EC 903-162-9. The justification for this read across is provided in IUCLID section 13.

Additional information
Acute toxicity oral
A limit test study conducted in accordance with the OECD 423 guideline reported that there were no deaths following a single oral dose of test article among rats dosed at 2000 mg/kg. No adverse clinical signs or macroscopic abnormalities were recorded in any animal and
no signs of systemic toxicity were noted during the study. The acute median lethal oral dose was found to exceed 2000 mg/kg, therefore the test material was considered to have no significant acute toxic risk if swallowed.
Acute toxicity dermal
A limit test study conducted in accordance with the OECD 402 guideline reported that there were no unscheduled deaths during the observation period following a single dermal administration of test article onto the dorsal trunk under a gauze patch among rats dosed at 2370 mg/kg. There were no systemic signs of toxicity noted in any animal at any observation time point and local findings at the dosing site were restricted to test item residues at the test site, which was seen in all animals on Day 2 only. The acute median lethal dermal dose was found to exceed 2370 mg/kg, therefore the test material was considered to have no significant acute toxic risk if in contact with skin. The acute dermal study is read across from material EC 903-161-3. The justification for use of this read across is detailed in IUCLID section 13. It is considered the LD50 of >2370 mg/kg bw for EC 903-161-3 is also representative of that of EC 903-162-9.
Acute toxicity inhalation
In accordance with Rule 8.5 of Annex VIII of the REACH Regulation, a study of the acute inhalation toxicity is not required, since studies of acute toxicity via oral exposure and via dermal exposure have been provided. Furthermore, the potential for inhalation exposure to occur is considered negligible.
Justification for selection of acute toxicity – oral endpoint
Key study conducted in accordance with OECD guideline 423 and GLP.
Justification for selection of acute toxicity – dermal endpoint
Read across of study conducted in accordance with OECD guideline 402 and GLP on an analogue substance. Justification for suitability for read across is provided in IUCLID section 13.
Justification for classification or non-classification
Acute Toxicity Oral
The acute oral LD50 is >2,000 mg/kg bw, therefore no classification for acute oral toxicity is required according to regulation (EC) 1272/2008 (CLP).
Acute Toxicity Dermal
An acute dermal LD50 value of >2,370 mg/kg bw was recorded in a relevant read across study (justification for read across is presented in IUCLID section 13), therefore no classification for acute dermal toxicity is required according to regulation (EC) 1272/2008 (CLP).
Acute Toxicity Inhalation
No acute inhalation toxicity data are available. Based on the low acute toxicity via both the oral and dermal routes of exposure, no classification for acute inhalation toxicity is proposed.
Specific Target Organ Toxicity - Single Exposure
No adverse clinical signs or macroscopic abnormalities were recorded in any animal, there were no remarkable bodyweight changes. Consequently, no classification for Single Exposure Specific Target Organ Toxicity is required under regulation (EC) 1272/2008 (CLP)
