The biodegradation of the SDIPB was determined in two biodegradability test. SDIBP was 11% degraded in ready biodegradability test according to OECD guideline 301B. The reference substance was 85% degraded after 28days and met the 10-day window requirement in key study based on CO2 evolution (Huntsman, 2012). The test substance was 36% degraded at the end of 56 days in enhanced ready biodegradation test according to OECD guideline 301B under GLP (Huntsman, 2013), and therefore cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No. 301.B. Similar biodegradation profile estimation was found to be "biodegrades fast", and "does not biodegrades fast" in QSAR linear model and non-linear model methodology, respectively, by EPISUITE 4.00. SDIBP is stable to hydrolysis. SDIBP is soluble in water and is neither sorptive nor volatile, nor bioaccumulative. The substance is therefore not persistent and is mainly partitioning to the water compartment.
