Description of key information
The density and relative density of an aqueous solution of the substance at 20ºC was determined to be 1.09 g/cm3 and 1.09, respectively.
The density and relative density of a freeze dried aqueous solution of a substance analogue (C12-C14 alkyl derivatives) at 20ºC was 1.33 g/cm3 and 1.33, respectively.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.33
Additional information
A gas comparison pycnometer was used for the determination of the density and relative density of a substance analogue (C12-C14 alkyl derivatives). A freeze dried aqueous solution was used in this study.
A pycnometer was used for the determination of the density and relative density of an aqueous solution of the substance. Both studies were performed in accordance with OECD 109 (1995) and according to GLP principles.
The rationale to read across the data is attached in Section 13.
