Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Overall solubility of detectable components at 23°C and at pH 5.2:

7.5 mg/L (of Dehydrogenated abietic acid and Abietic acid)

Estimated solubility of both not detectable components:

0.07 mg/L at 25°C

Key value for chemical safety assessment

Additional information

The determination was performed by HPLC according to OECD Guideline 105.

The test item is a mixture of four different components: Calcium salt of Monohydrogenated Abietic Acid (main component), Dehydro Abietic Acid, Abietic Acid and Bishydrogenated Abietic Acid.

The water test samples of this analyses have been analysed via HPLC-UV and evaluated at the wavelength 200 nm and 240 nm. In these test samples only two components of test item have been observed and evaluated: Abietic Acid and Dehydro Abietic Acid.

As the solubility of Monohydrogenated abietic acid (main component) and Bishydrogented abietic acid could not be detected therefore their solubilities have to generate by calculation using WSKOW v1.42.

- Monohydrogenated abietic acid (main component): 0.074 mg/L

- Bishydrogenated abietic acid: 0.061 mg/L
