Description of key information

Additional information

Ethytriglycol methacrylate (ET3EGMA) is a clear colourless to yellowish liquid at 20°C and 1013 hPa with an ester-like odour.

No melting point of ET3EGMAwas detected but a glass transition temperature at - 98°C at 1000 hPa (OECD 102).

The boiling point of ET3EGMA is reported to be 292°C at 1000 hPa (OECD 103).

The relative density of ET3EGMA is reported to be 1.02 at 20°C (DIN 51757).

In accordance with column 2 of REACH regulation annex VII, a granulometry test does not need to be conducted as the substance is a liquid.

The vapour pressure of ET3EGMA is reported to be 0.077 Pa at 20°C (OECD 104).

The n-Octanol/Water partition coefficient (log Kow) of ET3EGMA is reported to be 2.08 (OECD 117) at ambient temperature.

The water solubility of ET3EGMA is reported to be 61.4 g/L at 20°C (OECD 105).The substance is therefore very soluble (> 10000 mg/L) in water.

The flash point of ET3EGMA is reported to be 151 °C at 1013 hPa (ASTM D 93 / Pensky Martens Closed Cup).

The auto-ignition temperature of ET3EGMA is reported to be 260 °C at 1003 hPa (DIN 51794).

According to REACH Regulation (Annex XI, 1.), the study on flammability does not need to be conducted if the available data are sufficient for assessment. For ET3EGMA, a test on flash point is available. Pyrophoricity and flammability on contact with water are not expected based on a consideration of the structure of the substance.

In accordance with column 2 of REACH regulation annex VII, explosive properties testing does not need to be conducted as there are no chemical groups associated with explosive properties in the molecule. ET3EGMA is non-explosive.

In accordance with column 2 of REACH regulation annex VII, oxidising properties testing does not need to be conducted on the basis of chemical structure.

In accordance with column 1 of REACH regulation annex IX, stability in organic solvents testing is not required as stability of the substance is not considered critical. The test substance has no particular reactivity towards typical solvents and is not used in solution.

In accordance with column 2 of REACH regulation annex IX, dissociation constant testing does not need to be conducted as there are no dissociable groups.

The static viscosity of ET3EGMA is reported to be 4.91 mm²/s at 20°C and 2.97 mm²/s at 40°C (OECD 114).
