Prior dermal treatment the fur was removed mechanically from the dorsal skin of the animals over an area of approximately 30 cm2.
The adequate amount of the test substance was pasted and evenly spread on sheets (size 6x8 cm) of aluminium foil. Afterwards the foil covered with test compound was applied to the shaved and intact dorsal skin and fixed with an elastic plaster bandage (Fixomull and Elastoplast, width 8 cm, Beiersdorf AG) wrapped around the animal's body.
After the end of the 24 hours dermal exposure period the bandage was removed and the treated skin area rinsed with lukewarm water to wash off any non-absorbed remnants of the test compound.
The observation period after treatment was 14 days. Clinical symptoms were recorded twice daily (morning and afternoon), on weekends and public holidays only once a day. Body weight development was determined weekly. At the end of the observation period the animals were killed by CO2 asphyxiation, dissected and examined for macroscopically visible changes. - Statistics:

Additional information
Testing on the above endpoints gave the following results:
Acute toxicity: Oral.
- LD50: >2000 mg/kg
Acute toxicity: Dermal.
- LD50: >2000 mg/kg
Acute toxicity: Inhalation.
Not measured.
The test substance has a presumed very low vapour pressure and is a granular product; hence the potential for the generation of inhalable forms is low. In addition, production and use is done in a closed process without isolation of reaction products. The isolated product are dust free granules (non-dusty solid) which may be formulated into a liquid preparation of low volatility and the use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur. Dermal exposure is considered to be the appropriate route of exposure and has been assessed accordingly. No acute inhalation test was performed.
The following information is taken into account for any hazard / risk assessment:
Oral, inhalation and dermal acute toxicity are all considered.
Value used for CSA:
LD50 (oral): 2000 mg/kg bw
LD50 (dermal): 2000 mg/kg bw
Justification for classification or non-classification
The above studies have all been ranked reliability 1 according to the Klimisch et al system. This ranking was deemed appropriate because the studies were conducted to GLP and in compliance with agreed protocols. Sufficient dose ranges and numbers are detailed; hence it is appropriate for use based on reliability and animal welfare grounds.
The above results triggered no classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008). No classification for acute effects is therefore required.
