Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Sludge-water partitioning coefficients were measured for a range of fragrance ingredients including Cashmeran. A mixture of sludge and a buffer solution was incubated under sterile and anoxic conditions at 20°C for 21 days. Samples were taken at 5 points in time. After extraction they were analysed by GC/MS in SIM mode. Log Kd for the substance was 1.95 +/- 0.18 (adsorption) and 2.03 +/- 0.11 (desorption). With the fraction of organic carbon in sludge given as foc ~ 0.5, Koc is estimated to be 200.

Key value for chemical safety assessment

Koc at 20 °C:
