Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key information: Water solubility (OECD 105/EU Method A.6, shake flask method): < 1.0 mg/L at 20 °C - insoluble
Disregarded information: Target and read-across substance (1,3,4-Thiadiazolidine-2,5-dithione, reaction products with hydrogen peroxide and tert-dodecanethiol, No CAS, no EC) are considered as slightly soluble (Ziegenfuss, 1990 and Bouillon, 1998).

Key value for chemical safety assessment

Water solubility:
0.1 mg/L
at the temperature of:
20 °C

Additional information

The key value was determined according to OECD 105 / EU Method A.6 (Fox, 2012). The test substance can be considered as insoluble in water.

According to the harmonized OPPTS test Guideline 830.7840 (that is similar to OECD 105) the shake-flask method may pose difficulties in the case of surface-active materials. Therefore, the used method was maybe not appropriate for a surface-active material like the test substance; however, QSAR estimations confirm the insolubility of the test substance in water.
