Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A journal article that describes the methodology is also available (Meylan et al., 1996). The WSKOWWIN program estimates the water solubility of an organic compound using the compounds log octanol-water partition coefficient (log Kow). A brief description is given below.

Data Collection
A database of more than 8400 compounds with reliably measured log Kow values had already been compiled from available sources. Most experimental values were taken from a "star-list" compilation of Hansch and Leo (1985) that had already been critically evaluated (see also Hansch et al, 1995) or an extensive compilation by Sangster (1993) that includes many "recommended" values based upon critical evaluation.  Other log Kow values were taken from sources located through the Environmental Fate Data Base (EFDB) system (Howard et al, 1982, 1986).  A few values were taken from Section 4a, 8d, and 8e submissions the to U.S. EPA under the Toxic Substances Control Act (see http://www.syrres.com/esc/tscats_info.htm).
Water solubilities were collected from the AQUASOL dATAbASETM of the University of Arizona (Yalkowsky and Dannenfelser, 1990), Syracuse Research Corporation's PHYSPROP© Database (SRC,1994), and sources located through the Environmental Fate Data Base (EFDB) system (Howard et al, 1982, 1986). Water solubilities were primarily constrained to the 20-25oC temperature range with 25oC being preferred.
Melting points were collected from sources such as AQUASOL dATAbASETM,  PHYSPROP©, and EDFB as well as the Handbook of Chemistry and Physics (Lide, 1990) and the Aldrich Catalog (Aldrich, 1992).

Water Solubility Estimate from Log Kow (WSKOW v1.42): Water Solubility at 25 deg C (mg/L): 9.333e-033
Executive summary:

WSKOW predicted that Tris(2-decyltetradecyl) 1,2,4-benzenetricarboxylate has a Water Solubility at 25 °C: 9.333e-033 mg/L

Tris(2-decyltetradecyl) 1,2,4-benzenetricarboxylate is a similar substance in the registered subststance.

Description of key information

The water solubility at 25 °C was predicted based on a representative structure as 9.333e-033 mg/L. Based on the molecular size and composition the registered substance and its isomers can be considered as poorly soluble.

Key value for chemical safety assessment

Water solubility:
0 mg/L
at the temperature of:
25 °C
