In an acute oral toxicity study according to OECD 401, a group of fasted male and female SPF Wistar rats were given a single oral dose of Ethyltriglycol methacrylate at a limit dose of 5000 ml/kg bw and observed for 14days.
Oral LD50Combined = > 5000 ml/kg bw equals ca. 5100 mg/kg bw
OECD GHS Category 5 ranges from 2000 -5000 mg/kg bw and represents the lowest hazard category for classifying the acute oral toxicity of a chemical substance. ("Criteria for hazard Category 5 are intended to enable the identification of the test substances which are of relatively low acute toxicity hazard but which, under certain circumstances may present a danger to vulnerable populations". (OECD guideline 425 annex 4)).
Based on the results of this study ( LD50 limit test in male and female rats) Ethyltriglycol methacrylate is not classified according to EU-GHS and OECD GHS criteria.

In an acute dermal toxicity study (Limit test according to OECD 402), a group of 5 male and 5 female Wistar Crl: WI(Han) rats (source: Charles River, age: 9 weeks (m) and 13 weeks (f), weight: 236 to 249g (m) and 208 to 220 g (f)), were given a single dermal dose of undiluted Ethyltriglycol methacrylate (purity: 98.95%) at a dose of 2000 mg/kg bw. Animals were then observed for 14 days.
Dermal LD50Males/Females = > 2000 mg/kg bw
Ethyltriglycol methacrylate is practically nontoxic in rats based on the dermal LD50in rats. The substance has no toxicity category according to Annex VI to Commission Directive 2001/59/EC, REGULATION (EC) No 1272/2008 and according to OECD GHS criteria.
There were no treatment related signs of mortality or signs of toxicity but signs of irritation. All signs of irritation were reversible within the observation period.
This acute dermal limit test study is classified as acceptable. It does satisfy the requirements for an acute dermal study in the rats according to OECD 402.

Ethyltriglycol methacrylate is of low acute oral and dermal toxicity.
LD50: > 5100 mg/kg bw (oral rat, standard acute method) supported by LD50: > 2000 mg/kg/bw (oral, rat, standard acute method, limit test, single dose) is higher than 2000 mg/kg bw in rats.
