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.
