In an pre-guideline acute oral toxicity study, groups of fasted male and female SPF Wistar rats were given a single oral dose of Ethylene glycol dimethacrylate > 98.5 % at doses of 7.94, 8.89, 10.00, 11.20 and 12.60 ml/kg bw and observed for 14 days.
Oral LD50Combined = 8.30 ml/kg bw equals ca. 8700 mg/kg bw
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)).
Ethylene glycol dimethacrylate is of very low oral toxicity based on this LD50 test in males and females.

- Executive summary:
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: 231 to 247g (m) and 217 to 229 g (f)), were given a single dermal dose of undiluted Ethyleneglycol dimethacrylate (purity: 99.88%) at a dose of 2000 mg/kg bw. Animals were then observed for 14 days.
Dermal LD50Males/Females = > 2000 mg/kg bw
Ethyleneglycol dimethacrylate 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.

Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Additional information
Ethyleneglycol dimethacrylate is of low acute oral and dermal toxicity. LD50: 8700 mg/kg bw (oral rat, standard acute method) is higher than 2000 mg/kg bw in rats. In a recent GLP limit test performed according to OECD guideline 402, the dermal LD50 of EGDMA was found to be higher than 2000 mg/kg bw in rats with no mortality or relevant signs of toxicity.
Compliance to REACh requirements
The requirements are covered with reliable studies for all three exposure routes, all performed with the substance itself.
Justification for classification or non-classification
As oral and dermal LD50 are higher than 2000 mg/kg bw in rats, Ethyleneglycol dimethacrylate is not classified according to the Annex VI to the Directive 67/548/EEC and the CLP Regulation (EC) N° (1272-2008) nor according to UN-GHS.
