Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The indirect photolysis half-life was predicted using AOPWIN from the EPISUITE v4.11 program and the methodology described by Atkinson et al. (1985). The predicted half life of the measured constituents of the category (at equal or above 0.1% w/w) range between 0.056 and 5.88 days, considering 12-h daylight.

According to REACH Annex VIII, a hydrolysis study does not need to be conducted if the substance is readily biodegradable, or the substance is highly insoluble in water. However, evaluation of the molecular structure of the constituents indicates that this endpoint is scientifically not necessary for this category as none of the constituents contain any hydrolysable groups such as hydroxyl, sulfhydryl, carbonyl, carboxyl, amino, or phosphate groups. Therefore, conducting this type of study would not yield any useful information about the possible decomposition of constituents in the environment. Therefore, according to REACH Annex XI Section 1.2, the study can be waived because testing does not appear to be scientifically necessary based on the structures of the constituents.
