A mixture of: esters of C14-C15 branched alcohols with 3,5-di-t-butyl-4-hydroxyphenyl propionic acid; C15 branched and linear alkyl 3,5-bis(1,1-dimethylethyl)-4-hydroxybenzenepropanoate; C13 branched and linear alkyl 3,5-bis(1,1-dimethylethyl)-4-hydroxybenzenepropanoate

Biodegradation in soil

Administrative data

Endpoint:

biodegradation in soil: simulation testing

Type of information:

experimental study planned

Remarks:

See below

Study period:

Upon receipt of ECHA decision.

Justification for type of information:

In accordance with Chapter R.11: PBT/vPvB assessment, Figure R.11—3: Integrated Assessment and Testing Strategy for persistence assessment – maximising data use and targeting testing, it is considered appropriate to assess this endpoint without the need to assess via the OECD 309 study. The substance is not readily biodegradable, but shows a propensity towards inherent biodegradation. The log Koc was above 5.0 for the test substance at a temperature of 20˚C and Koc is set at > 100,000. The substance therefore has a propensity to absorb to sludge, soil and sediment based on the available information. It is considered appropriate therefore to conduct this test as part of hazard assessment to preclude the possibility of "P".
