Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A test was conducted on the substance in itself in order to evaluate the water solubility of AP1300S. The study was conducted according to the OECD Guideline 105. Based on the observations reported above the solubility in water was stated as < 20 µg/L (mean +standard deviation).

Moreover the solubility of the AP 1300 S has been estimated by two different tools which predicted very similar values:

WATERNT v1.01 tool

9.72e-007 mg/l

WSKOW v1.42

1.259e-011 mg/l

In both cases, the substance is estimated to be insoluble in water. The water solubility value reported for the Similar Substance 01 (CAS 21850-44-2) in the ECHA website is lower than 0.1 mg/l, confirming the behaviour in water expected for AP 1300 S.

Considering the whole data set available for AP1300S, the substance is considered as insoluble in water.
