EC number: 425-220-8
CAS number: 5945-33-5
LD50 Oral: >2000mg/kg bw (OECD 401, GLP)LD50 Dermal: >2000mg/kg bw (OECD 402, GLP))
In acute oral toxicity studies carried out in 10 male/10 female
and 5 male/5 female animals (Annex V guideline limit tests, 5000mg/kgbw)
the LD50 was determined to be >5000mg/kg bw. In two further acute oral
toxicity studies carried out in 5 male and 5 female animals (guideline
limit tests, 2000mg/kg bw) the LD50 was determined to be >2000mg/kg bw.
As one of these tests was carried out in accordance with OECD 401/GLP,
it was chosen as the key study and the LD50 value >2000mg/kg bw was
chosen as the key value for the acute oral toxicity endpoint.
