Endpoint:
biodegradation in water: simulation testing on ultimate degradation in surface water
Type of information:
experimental study planned
Study period:
TBA
Justification for type of information:
Substance name: 2,2'-[oxybis(methylene)]bis[2-ethylpropane-1,3-diol]

-No existing GLP studies available for this endpoint
-No existing non-GLP studies available for this endpoint
-No historical environmental data available for this endpoint
-No existing (Q)SAR information can properly assess this endpoint
-No sufficient information available that could fulfill the standard information requirement through the weight of evidence approach
-No information from structurally similar substance can be used to fulfill the standard information requirement through grouping and read-across

Considerations that the specific adaptation possibilities of annexes VI to X (and column 2 thereof) of the REACH regulation are not adequate to generate the necessary information:
Aerobic Mineralization in Surface Water- Simulation Biodegradation Test design is the standard information requirement for substance registered for 100 tons or more per year (Annex IX, Section 9.2.1.2, column 1, of the REACH regulation).
Qualifier:
according to guideline
Guideline:
OECD Guideline 309 (Aerobic Mineralisation in Surface Water - Simulation Biodegradation Test)
GLP compliance:
yes

Aerobic and Anaerobic Transformation in Aquatic Sediment Systems Test design is the standard information requirement for substance registered for 100 tons or more per year (Annex IX, Section 9.2.1.4, column 1, of the REACH regulation).
Qualifier:
according to guideline
Guideline:
OECD Guideline 308 (Aerobic and Anaerobic Transformation in Aquatic Sediment Systems)
GLP compliance:
yes

Description of key information

A testing proposal is suggested on these endpoints as no available studies neither GLP or non-GLP are available to cover the information requirements for this tonnage level.

Key value for chemical safety assessment
