Description of key information
With regard to the acute toxicity of the registered substance, key studies for the oral and dermal exposure routes are available. Using the acute toxic class method according OECD test TG 423, a single oral application of Glucamide OL to rats at a dose of 2000 mg/kg body weight was associated with unspecific signs of toxicity but not mortality. Based on the results, the LD50 cut-off value of Glucamide OL is 5000 mg/kg body weight.
The acute dermal toxicity of the registered substance was evaluated in an OECD 402 study according to GLP. After topical treatment with the limit dose of 2000 mg/kg body weight neither mortality nor significant clinical symptoms of intoxication were observed. The LD50 after dermal treatment was established to be greater 2000 mg/kg body weight.

- Observation Period
All animals were observed for 14 days after dosing for general clinical signs, morbidity and mortality.
Weight Assessment
The animals were weighed on day 1 (prior to the administration) and on days 8 and 15.
Clinical Examination
A careful clinical examination was made several times on the day of dosing (at least once during the first 30 minutes and with special attention given during the first 4 hours post-dose). As soon as symptoms were noticed they were recorded. Thereafter, the animals were observed for clinical signs once daily until the end of the observation period. All abnormalities were recorded.
Cageside observations included changes in the skin and fur, eyes and mucous membranes. Also respiratory, circulatory, autonomic and central
nervous systems and somatomotor activity and behaviour pattern were examined. Particular attention was directed to observations of tremor,
convulsions, salivation, diarrhoea, lethargy, sleep and coma.
Pathology
At the end of the observation period the animals were sacrificed with an overdosage of sodium pentobarbital injected intraperitoneally (Narcoren®, Merial; lot no. 231073, expiry date: 31/07/2016) at a dosage of approximately 8 mL/kg bw.

LD50 cut-off (rat): 5000 mg/ kg bw - Executive summary:
The acute oral toxicity of C18/C18 unsatd.-Glucamide was investigated in a GLP compliant study according to OECD TG 423. Two groups, each of three female WISTAR Crl: WI(Han) rats, were treated with the test item by oral gavage administration at a dosage of 2000 mg/kg body weight. The test item was suspended in the vehicle aqua ad injectionem (sterile water) at a concentration of 0.2 g/mL and administered at a dose volume of 10 mL/kg. All animals used in the study after their entrance at BSL were allowed to acclimatise to the laboratory conditions for at least 5 days. The animals were observed on delivery, on inclusion in the study and before administration for mortality/morbidity and other clinical signs. All animals were examined for clinical signs several times on the day of dosing and once daily until the end of the observation period. Their body weights were recorded on day 1 (prior to the administration) and on days 8 and 15.All animals were necropsied and examined macroscopically.

All animals survived until the end of the study showing signs of toxicity. Throughout the 14-day observation period, the body weight gain of the test animals was within the normal range of variation for this strain. At necropsy, no treatment-related macroscopic findings were observed in any animal of any step. The most relevant clinical findings in the animals treated with the test item at a dose of 2000 mg/kg bw were reduced spontaneous activity, wasp waist, piloerection and hunched posture. The animals recovered from all symptoms by day 3 of treatment. Under the conditions of the present study, a single oral application of the test item C18/C18 unsatd.-Glucamide to rats at a dose of 2000 mg/kg body weight was associated with signs of toxicity but not mortality.
The median lethal dose of C18/C18 unsatd.-Glucamide after a single oral administration to female rats, observed over a period of 14 days is: LD50cut-off (rat): 5000 mg/ kg body weight

Acute toxicity: via inhalation route
Link to relevant study records
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size

- Preparation of the Animals
The animals were marked for individual identification by tail painting.
Approximately 25 hours before the test, the fur was removed from the dorsal area of the trunk using an electric clipper.
Care was taken to avoid abrading the skin, and only animals with healthy intact skin were used.
No less than 10% of the body surface was cleared for the application.
Prior to the application a detailed clinical observation was made of all animals.
Application
The test item was applied at a single dose, uniformly over an area which was approximately 10% of the total body surface.
The test item was held in contact with the skin by a dressing throughout a 24-hour period. The dressing consisted of a gauze-dressing
and non-irritating tape and was fixed with an additional dressing in a suitable manner. - Duration of exposure:
- The test item was held in contact with the skin throughout a 24-hour period. At the end of the exposure period the residual test item was removed using corn oil.
- Doses:

- Details on study design:
- Observation period:

At the end of the observation period the surviving animals were sacrificed with an overdosage of pentobarbital injected intraperitoneally (Narcoren®, Merial) at the dosage of approximately 8 mL/kg bw. All animals were subjected to gross necropsy. All gross pathological changes were recorded and in case of findings the tissues were preserved for a possible histopathological evaluation. The preserved tissues of which no histopathological evaluation was made will be discarded 3 months after the release of the final report unless otherwise agreed upon with the sponsor.

Individual reactions of each animal were recorded at each time of observation.
Toxic response data were recorded by sex and dose level.
Nature, severity and duration of clinical observations were described.
The body weight changes were summarised in a tabular form.
Necropsy findings were described.

Additional information
Justification for classification or non-classification
Based on the results from an OECD TG 423 guideline study which revealed a LD50 cut-off value of 5000 mg/kg body weight, no classification according to CLP of Glucamide OL is warranted with regard to acute oral toxicity.
Based on the results from an OECD 402 guideline study which revealed a LD50 greater 2000 mg/kg body weight, no classification of Glucamide OL according to CLP is warranted with regard to acute dermal toxicity.
