EC number: 252-091-3 | CAS number: 34562-31-7
Oral LD50 > 500 mg/kg bw, dermal LD50 > 1000 mg/kg bw
The oral LD50 of the test material is ≥500 mg/kg bw according to a U.S. DOT guideline study.
Erythema was noted on all animals after the 24h exposure period, but resolved in all animals by day 5.
The substance has an oral LD50 > 500 mg/kg bw; this meets the criteria for classification as acute oral toxicity 4 (300 mg/kg > LD50 < 2000 mg/kg). The dermal LD50 is > 1000 mg/kg bw and evaluated as "non-toxic" with lethality reported, though this single dose is not sufficiently high to meet GHS requirements for non-classification. Due to the absence of any animal deaths at 1000 mg/kg bw, and the evaluation of "non-toxic" according to U.S. DOT guidance, the substance is not classified for acute toxicity by the dermal route. However, due to an indication of skin irritation and severe damage to the eye, protection from dermal exposure is recommended by the use of personal protective equipment.
