Endpoint summary

Description of key information

In Compliance with the OECD 401 Guidelines:

The aim of this study was to assess the potential toxicity and lethality of a single oral exposure of 2 000mg/kg body weight.

The rats were observed up to 14 days after the oral dose.

No mortality occured, no clinical sign was observed, individual growth weight of the rats remain normal and regular.

Effects on organs: did not show any visible organic or tissular lesion.

=> LD50 oral, rat > 2000 mg/kg bw/d

 

In Compliance with the OECD 402 Guidelines :

A limit test study was conducted to assess the acute toxicity of the test item by dermal route.

2000 mg/kg body weight of the test item was administrated to 5 male and 5 female Sprague-Dawley rats.

- There were no deaths

- No signs of systemic toxicity were noted during the study

-All animals showed expected gain in bodyweight during the study

- No abnormalities were noted at necropsy

The acute dermal (LD0) of the test animal, lipacide UG, in the Sprague-Dawley CD strain was found to be higher than 2000 mg/ kg body weight.

The test item does not need to be classified in accordance with the Comission Directive 93/21/EEC.

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

Details on test animals or test system and environmental conditions:

Five male and five female Sprague Dawley CD (Crl: CD (SD)IGS BR) strain rats were supplied by Charles River (UK), Kent. On receipt the animals were randomly allocated to cages. The females were nulliparous and non-pregnant. After an acclimatisation period of at least five days the animals were selected at random and given a number unique within the study by indelebile ink-marking on the tail and a number written on a cage card. At the start of the study the males weighed 200 to 206 g, and the females 202 to 225 g, and were approximately eight weeks of age.

The animals were housed in suspended polypropylene cages fournished with woodflakes. The animals were housed individually during the 24 hour exposure period and in groups of five, by sex for the remainder of the study. Free access to mains drinking water and food (rat and mouse SQC expanded Dict No.1, special diets services limite, Witham, Essex, UK) was allowed throughout the study. The diet, drinking water and bedding were routinely analysed and were considered not to contain any contaminants that could reasonably be expected to affect the purpose or integrity of the study.

The temperature and relative humidity were set to achieve limits of 19 to 25°C and 30 to 70% respectively. Any occasional devitaions from these targets were considered not to have affected the purpose or integrity of the study. The rate of air exchange was at least 15 changes per hour and the lighting was controlled by a time switch to give twelve hours light and twelve hours darkness.

Type of coverage:

semiocclusive

Vehicle:

water

Remarks:

distilled water

Details on dermal exposure:

One day before treatment the back and the flanks of each animal were clipped free of hair.
a group of five male and five female rats were treated with the test material at a dose level of 2000 mg/kg. The appropriate amount of test material, moistened with distilled water, was applied as evenly as possible to an area of shorn skin (approximately 10% of the total body surface). A piece of surgical gauze was placed over the treatment area and semi-occlued with a piece od self adhesive bandage. The animals were caged individually for the 24-hour exposure period. Shortly after dosing, the dressings were examined to ensure that they were securely in place.

Duration of exposure:
