Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
An experimental determination is not applicable as the test substance is surface active.
However, log Pow values were calculated for individual constituents using KOWWIN v.167, in order to determine a log Pow value usable for a conservative environmental risk assessment of the aquatic compartment:
The estimated values of the individual constituent are as follows:
log Pow of "structure A"= 1.06 to 5.97
log Pow of "structure B"= 4.6 to 14.4
log Pow of "structure C"= -1.8
log Pow of "structure D"= 1.1 to 6
log Pow of "structure E"= 8.5 to 23
Key value for chemical safety assessment
Additional information
The partition coefficient n-octanol/ water (Pow) cannot be determined, because the test item consists of a mixture of compounds with different properties and because the test item is surface active.
The estimation of the Pow from the solubilities of the test item in water and in n-octanol is not possible either, because the test item is partly soluble in water and a defined water solubility cannot be determined.
For getting a reasonable value for a a conservative environmental risk assessment of the aquatic compartment an additional calculation was provided. The log Pow values of the individual constituent have been generated using KOWWIN (v1.68) module of software EPI Suite v.4.11.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
