20 °C

Additional information

In the key study, the material was reported to be miscible in all proportions with water at 20.0 ± 0.5 °C, by visual assessment, using a flask method, designed to be compatible with Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The standard EC A6/ OECD 105 methodology was not applicable to this test item, due to its miscibility with water. A water solubility of miscible with water at 20°C was also reported in a well-documented company supporting study which meets generally accepted scientific principles. The original reference was not available for review and no further information is available. Consequently, the reliability of the data is with restriction. In 2001 the American ACGIH reported a water solubility of miscible with water at 20°C. The result was sourced from a secondary source which has been subject to peer-review and which is recommended for use in chemical safety assessment by the ACGIH. The result is considered to be reliable. A water solubility of 1,000,000 mg/l at 20°C (QSAR) was also obtained using appropriate predictive methods. The substance is known as fully water miscible.

For the purpose of completing the chemical safety assessment, the water solubility was assumed to be 100,000 mg/L, which is the maximum water solubility value allowed in Euses.
