- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- See attached background material, attached further below in the present section.
- Qualifier:
- according to guideline
- Guideline:
- other: REACH guidance on information requirements and chemical safety assessment, chapter R.6: QSARs and grouping of chemicals, May 2008.

Result Classification: 5.00 -> hours 4.00 -> days 3.00 -> weeks
(Primary & Ultimate) 2.00 -> months 1.00 -> longer
Biowin5 (MITI Linear Biodeg Probability): 0.8471
Biowin6 (MITI Non-Linear Biodeg Probability): 0.8776
A Probability Greater Than or Equal to 0.5 indicates --> Readily Degradable
A Probability Less Than 0.5 indicates --> NOT Readily Degradable
Biowin7 (Anaerobic Linear Biodeg Prob): 0.9146
A Probability Greater Than or Equal to 0.5 indicates --> Biodegrades Fast
A Probability Less Than 0.5 indicates --> Does NOT Biodegrade Fast - Validity criteria fulfilled:
- not applicable
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Sodium isostearoyl lactylate (ISL) is predicted to be readily biodegradable by the (Q)SAR model BIOWIN v4.10.
- Executive summary:
Sodium isostearoyl lactylate (ISL) is predicted to be readily biodegradable by the (Q)SAR model BIOWIN v4.10.
Reference
