Additional information

SDIBP has a very low logPow (-3.11) and LogKoa and Koc values of SDIBP was found as 8.16 and 238.9 L/kg in QSAR KowWin/HenryWin prediction method and MCI method by EPISUITE 4.00, respectively. An environmental assessment of hydrotropes was conducted under the Organisation for Economic Co-operation and Development (OECD) Screening Information Data Sets (SIDS) for High Production Volume (HPV) Program via the Global International Council of Chemical Associations (ICCA) Hydrotropes Consortium (Stanton et al., 2010). The assessment was based on a search for and evaluation of available data on physical–chemical properties, biodegradability, removal by wastewater treatment, and aquatic toxicity. Partitioning, once released into the environment, and exposure in surface waters were modeled for consumer use and manufacturing scenarios relevant to the United States, Europe, and Australia. The models indicated >99% of the hydrotropes will partition to water. Furthermore, given the low potential for hydrotropes reaching the terrestrial compartment and their lack of persistency or bioaccumulation, the focus of the assessment was on the aquatic environment, specifically the water compartment. The closest a predicted environmental concentration came to the toxicity threshold (PEC/PNEC ratio) is 0.125.

Based on the environmental assessment and QSAR prediction, therefore SDIBP is likely to have a very low potential for absorption and bioaccumulative in the environment.
