Description of key information

Key study: Based on the experimental results on analogue substance methyltriacetoxysilane (OECD 301F and GLP), the read-across approach was applied and NOEC (28 d) for propyltriacetoxysilane was calculated to be 105.45 mg/L. 

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
105.45 mg/L

Additional information

Key study: Read-across from experimental data on analogue substance Methyltriacetoxysilane:

In the ready biodegradability test was perfomed according to OECD Guideline 301 F on analogue methyltriacetoxysilane the 28 day-NOEC was determined to be 100 mg/L since the substance degraded well and did not inhibit the degradation of the toxicity test. Based on these results, the read-across approach was applied and 28 day-NOEC for propyltriacetoxysilane was calculated to be 105.45 mg/L under test conditions.
