Description of key information

Two separate TGD-approved handbooks agree that the substance is soluble in water.

Key value for chemical safety assessment

Water solubility:
181 000 mg/L
at the temperature of:
25 °C

Additional information

Information regarding water solubility of SBA was sourced from two separate handbooks. Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Edition) and CRC Handbook of Chemistry and Physics (81st Ed), which are known to contain peer-reviewed data of Klimisch-2 reliability, report that the substance is "soluble in about 12 parts water" (equivalent to 7.7 vol%) and “very soluble”, respectively. No information on solution temperature or pH was reported. Water solubility of SBA also was sourced from the Handbook of Environmental Data on Organic Chemicals (3rd Ed.), and from a publicly available document by Heftner (1984), reporting water solubility values of 125,000 mg/L at 20°C and 181,000 mg/L at 25ºC, respectively.  No information on pH was reported in either source. Although comparable, these data have been obtained from secondary sources, and as such are of Klimisch-4 reliability and the validity of the sources cannot be assessed.
