Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Water solubility
Administrative data

Description of key information
The water solubility of Dodecane-12-lactam, manufacturing of, by-products from, distillation residues, or 10-undecenoic acid was evaluated in a GLP-study performed in accordance with OECD testing guideline 105 (flask method)
As the test item is present as a complex reaction product of unknown and variable composition, standard tests for water solubility are not typically appropriate for the test item: phase separation and a range of solubilities were observed from 0.4103 to 0.8460 g/L (depending on pH and the substance considered).
Key value for chemical safety assessment
- Water solubility:
- 612.5 mg/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of Dodecane-12-lactam, manufacturing of, by-products from, distillation residues, or 10-undecenoic acid was evaluated in a study performed in accordance with OECD testing guideline 105 and GLP requirements.
The flask method was used.
As the test item is present as a complex reaction product of unknown and variable composition, standard tests for water solubility are not typically appropriate. Therefore phase separation and a range of solubilities were observed and portions of the test item remained undissolved :
Milli-RO water = 0.4671 g/L (Dodecane-12-lactam principal component)
= 0.9368 g/L (combined hydrocarbon structures of test item)
pH 4 buffer = 0.4280 g/L (Dodecane-12-lactam principal component)
= 0.4560 g/L (combined hydrocarbon structures of test item)
pH 7 buffer = 0.4103 g/L (Dodecane-12-lactam principal component)
= 0.6125 g/L (combined hydrocarbon structures of test item)
pH 9 buffer = 0.4346 g/L (Dodecane-12-lactam principal component)
= 0.8460 g/L (combined hydrocarbon structures of test item)
Validity criteria were fulfilled.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
