Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The studies were performed in 1974, prior to availability of OECD guidelines and EU-testing methods, but however do follow scientific principles.
Oral toxicity was tested at six different dose levels with 10 rats each, whereas deraml toxicity was only tested at one dose level (5 g/kg bw) as this value already was lower than the LD50 (1 out of 5 animals died). Symptom observed were recorded and reported.
GLP compliance:
no
Remarks:
pre-dates GLP
Test type:

Limit test:
no

Effect levels
Sex:
male/female
Dose descriptor:
LD50
Effect level:
2 300 mg/kg bw
Based on:
test mat.
95% CL:
>= 1 893 - <= 2 707
Mortality:
At 5 g/kg bw all animals died (8 on day 1, 1 on day 2 and 1 on day 4)
At 3 g/kg bw eight animals died on day 1, but none thereafter
At 2.5 g/kg bw five animals died on day 1, but none thereafter
At 2 g/kg bw 3 animals died on day 1 and none thereafter
At 1 g/kg one animal died on day 1 and none thereafter
At 0.5 g/kg bw none of the animals died
Clinical signs:
other: Ataxia, depression, loss of righting reflex, increased respiration, tremors and twitches were observed symptoms.

Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Remarks:
not applicable to CLP
Conclusions:
The LD50 determined was 2.3 ±0.407 g/kg bw.
Executive summary:

The substance was assessed for acute oral toxicity to rats, by applying six different doeses (0.5, 1, 2, 2.5, 3 and 5 g/kg bw) to groups of 10 rats each (males and females). Mortality was observed at all dose groups except of 0.5 g/kg bw. The LD50 determined was 2.3 ±0.407 g/kg bw. Symptoms observed were ataxia, depression, loss of righting reflex, increased respiration, tremors and twitches.
