Additional information

Phototransformation in air

After evaporation or exposure to air, methyl formate and its hydrolysis product methanol and formic acid will be slowly degraded by photochemical processes.

Hydrolysis

Parent compound: In contact with water, the substance will hydrolyse slowly. Under alkaline conditions the substance will hydrolyse rapidly.

Hydrolysis product formic acid: The hydrolysis of the formic acid is not expected. In addition, the substance is readily biodegradable according to OECD criteria.

Hydrolysis product methanol: The substance is readily biodegradable according to OECD criteria.

 

Biodegradation in water: screening tests

The substance as well as its hydolysis products (methanol and formic acid) are readily biodegradable according to OECD criteria.

Biodegradation in water and sediment: simulation tests

In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.2 and 9.2.1.4, Column 2, the study does not need to be conducted if the substance is readily biodegradable. Methyl formate and its hydrolytic products are experimentally assessed to be readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no biodegradation studies in surface water and sediment will be provided for substances.

Biodegradation in soil

In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.3, Column 2, the study does not need to be conducted if the substance is readily biodegradable. Methyl formate and its hydrolytic products are experimentally assessed to be readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no biodegradation studies in soil will be provided for substances.

 

Bioaccumulation

Significant accumulation of methyl formate and its hydrolysis products (methanol and formic acid) in organisms is not to be expected.

Adsorption / desorption

Adsorption of methyl formate and its hydrolysis products (methanol and formic acid) to the solid soil phase is not expected.

Henry's Law constant

From the water surface, methyl formate will slowly evaporate into the atmosphere. The hydrolysis products methanol and formic acid are not expected to significantly volatilize from the aquatic compartment.
