Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Computer modelling predicts that, if released to the environment, over half of LAS would partition to soil, and the remainder would be found in water and sediment. If released to water, it is predicted to be removed by biodegradation in under two days; when released to soil, removal is predicted to take 28 days. Similar investigations using laboratory studies and computer modeling indicate that when commercial LAS is mixed with activated sludge, almost all of the LAS (92 -98%, Kp=2,500 L/kg, log Kp= 3.4) would sorb to the sludge in under 10 minutes, and that while most of the added LAS sorbed to the sludge, it was available for biodegradation, which removed more than 99%. LAS is not anticipated to be found in air to any significant amount due to the low vapor pressure, calculated as 3 x 10-13Pa for C12LAS.
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.
