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.

Additional information

The substance Isotridecanol, ethoxylated, < 2.5 EO (CAS 69011-36-5) is considered to be readily biodegradable. Alcohol ethoxylates, like Isotridecanol, ethoxylated, will be rapidly mineralised in the environment and thus abiotic degradation by hydrolysis is not a relevant degradation pathway for the substance. Abiotic degradation in water, soil, sediment and air is generally not expected because of the chemical structures of alcohol ethoxylates.

The adsorption potential of alcohol ethoxylates is depends on the properties of the AE substance. Properties like chain length of the alcohol and level of ethoxylation drive the adsorption potential, but it also depends on the properties of the soil, sediment or suspended solids to which the substance adsorbs. The log Koc values estimated for Isotridecanol, ethoxylated, < 2.5 EO (CAS 69011-36-5) range from 2.532 to 3.263 when calculated with the log Kow based method. The log Koc range calculated by the MCI based method is 2.376 – 2.645.The available QSAR calculations demonstrate a decreasing potential for adsorption potential with increasing level of ethoxylation.

Experimentally determined BCF-values given for pure homologues and summarized in the publication of Tolls et al. (2000) are used as read-across data for the endpoint bioaccumulation in water. It can be stated that bioaccumulation of alcohol ethoxylates is regarded to be negligible as the surfactants will be rapidly metabolised.
