Summary of acute toxicity

Key value for chemical safety assessment

Acute toxicity: via oral route

Endpoint conclusion
Dose descriptor:
LD50
Value:
2 000 mg/kg bw

Acute toxicity: via dermal route

Endpoint conclusion
Dose descriptor:
LD50
Value:
2 000 mg/kg bw

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 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 Klimish 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.
