Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Significant accumulation in organisms is not to be expected.
Key value for chemical safety assessment
Additional information
The substance consists of both an organic pigment (CAS 147-14-8) and a tensid (dodecylbenzylsulfonic acid). The organic pigment is neither well soluble in water (4 - 9 µg/L) nor in octanol (0.1 -0.4 µg/L). Therefore bioaccumulation of this pigment is not expected (logPow -1.95 to -1.0). The tensid, is also not bioaccumulative in organisms since the BCFs for surfactants are reported as being comparatively low and are generally below the conventional level of concern (McWilliams & Payne, 2001). Commercial LAS, C11.6 alkyl chain length, has a BCF of 66 l/kg (Tolls et al. 1997).
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.
