Description of key information
Additional information
Dichloromethane is a colourless liquid with a melting point of -95°C and a boiling point of 40 ºC at 101.3 kPa. The relative density of dichloromethane at 25 ºC is 1.32 g/cm3. (All from CRC Handbook of Chemistry and Physics, 1994). This substance is not produced nor transported as an aerosol nor as a gas under pressure.
The vapour pressure of dichloromethane is 470 hPa at 20°C. The octanol/water partition coefficient (log Pow) is 1.25, the water solubility is 13.2 g/l at 25 ºC (All from: Illustrated Handbook of Physical-Chemical Properties and Environmental Fate for Organic Chemicals, 1993). The viscosity of the substance is 0.425 mPa s (McGovern, 1943).
In accordance with
column 2 of REACH Annex VII, data on the particle size are not needed as
the substance is a liquid. Based on its structure, dichloromethane is
not expected to be surface active. The substance remains undissociated
in water as it does not contain chemical groups which are capable of
dissociation. n the particle size are not needed as the substance is a
liquid. Based on its structure, dichloromethane is not expected to be
surface active. The substance remains undissociated in water as it does
not contain chemical groups which are capable of dissociation. In
accordance with column 1 of REACH Annex IX, the study is not required,
as the stability of the substance is not considered to be critical. The
substance is a chlorinated hydrocarbon. This kind of substances usually
does not react with common organic solvents like alkanes, alcohols,
ketones, aromatic hydrocarbons and halogenated hydrocarbons.
The self-ignition temperature of dichloromethane is 605ºC at 101.3kPa (CRC Handbook of Chemistry and Physics, 1994). The substance is non-flammable (CRC Handbook of Chemistry and Physics, 1994), does not have pyrophoric properties and does not react with water. Based on this, dichloromethane does not need to be classified as flammable according to EU Directive 67/584/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008. The substance does not contain chemical groups associated with explosive or oxidising properties, therefore classification for these hazards is not warranted according to EU Directive 67/584/EEC and Regulation (EC) No. 1272/2008 on Classification, Labelling and Packaging of Substances and Mixtures (CLP Regulation).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
