Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

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 for the parameters tested:

 Acute toxicity: Oral: LD50: 

Two studies are available for this endpoint:

1) LD50 >2000 mg/kg (K1 study)

2) LD50 > 5000 mg/kg (K3 study).

For the purposes of risk assessment, the lower value is taken; however neither value is indicative of toxicity by oral ingestion.

Acute toxicity: Dermal:

Two studies are available for this endpoint:

1) LD50 >2000 mg/kg (K1 study)

2) LD50 >2000 mg/kg (K3 study).

For the purposes of risk assessment, the lower value is taken; however neither value is indicative of toxicity by dermal application.

Acute toxicity: Inhalation: Not measured.

 

The substance is of sufficiently low vapour pressure to preclude exposure via inhalation at significant volumes. In addition, production and use is done in a controlled process precluding the substance forming aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur. This is also applicable to the use of the substance. 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 to 3 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. The majority of the information has been provided from a migrated NONS file referring to studies, which are more than 12 years old, with the permission of ECHA.

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.
