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


The soil adsorption coefficient of benzenesulfonic acid, di-C10-14-alkyl derivs., sodium salts was determined by the computer program KOCWIN v2.00 (EPIWIN software v4.11) by US-EPA (ATL, 2017).The EPIWIN estimates the organic carbon-normalized adsorption coefficient for soil (and for sediment), which is designated as Koc. Two different models are used for this estimation: the Sabljic molecular connectivity (MCI) method as well as with the traditional method which is based on logPow. The traditional method gives a logKoc of 5.793 and the MCI method reveals a comparable value of 7.101 as result. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
