Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Sulfosuccinate of Lanoline Alcohol is a complex substance that can disperse into the water and with surface active properties, therefore we can say that water is an interested compartment.
The substance is estimated as non hydrolysable. In addition to the hydrolysis, information on the biodegradability of chemicals may be used for classification and labelling on the hazard assessment, chemical safety assessment and persistency assessments (for PBT/vPvB assessment). Sulfosuccinate of Lanolin Alcohol was found to be not ready biodegradable under the conditions applied in a Manometric Respirometry test, having not reached the pass level (60% biodegradation) during the 10-day window (range of biodegradation: 11.2% - 31.6%) and having showed a maximum biodegradation of 44.8% during the test period (mean of two replicates). Even so, the test item did not show any inhibitory effects on the microorganism activity in the toxicity control at 10th day of test period.
The biodegradability curve can show that, despite the low final value of biodegradability, the test item increases its capacity to be biodegrade during time.
Bioaccumulation and adsorption/desorption are based on the physicochemical properties (octanol-water partition coefficient log Kow < 3).
A BCF for Risk assessment could not be estimated due to the very complexity of the molecule. Estimation on BCF/BAF (EPIWIN) for Log Kow < 1.0 the derived QSAR is assigned a log BCF 0.50.
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.
