Description of key information
Water solubility determinations (following EU Method A.6) have been run on both ethyl hexyl methoxycrylene (EHMC)(EC Number 700-213-5) and undecenyl methoxycrylene (UMC)(EC Number 700-824-2). In addition, the water solubility of EHMC was determined in test media from a Daphnia magna 21-day reproduction test.
Key value for chemical safety assessment
- Water solubility:
- 0.04 mg/L
- at the temperature of:
- 20 °C
Additional information
The two chemical substances, EHMC and UMC, are closely related in molecular structure, molecular mass, and functional groups. The only difference between these substances chemically is the alcohol group on the ester functionality. For EHMC, the alcohol moiety is 2-ethylhexyl- (branched eight-carbon chain), and for UMC the alcohol moiety is undecenyl (straight eleven-carbon chain with a C=C alkene bond at the end of the chain). These two substances, based on their close similarity of molecular structure and functionality, are expected to have similar properties. UMC information is being used as read across data for toxicological endpoints for this registration. In the case of EHMC, the water solubility was determined by measurement to be 0.00004 g/l at 20º C. The water solubility for UMC was determined by the same method to be 0.00017 g/l at 20º C. The close agreement of these water solubility values supports the similarity of properties and read across approach for EHMC and UMC.
The water solubility of EHMC was determined without the aid of a co-solvent or auxiliary solvent in the test media used for the Daphnia magna 21 -day reproduction toxicity test. The use of solvents, in some cases, has been recognized to contribute to ecotoxicological effects which are not found when test organisms are exposed to the substance without the use of an auxiliary solvent. Using a slow-stir method and without auxiliary solvent, the concentration of EHMC ranged from 0.0000427 to 0.000151 mg/l for filtered samples and 0.000717 to 0.00182 mg/l for centrifuged samples.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
