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.

Additional information

The ready biodegradability of Hexyl salicylate has been determined according to the OECD guideline 301F. In the conditions of the test, Hexyl salicylate undergoes 91 % biodegradation after 28 days. Biodegradation reaches 82 % at the end of the 10-day window (days 2 to 12).

Thus, Hexyl salicylate should be regarded as readily biodegradable according to this test.

In addition at the concentration used in the test (100 mg/L), it is not inhibitory to the micro-organisms.

The logKow value of Hexyl salicylate is 5.50 according a study conducted by Rudio, J. in 1996.

In addition, data was taken from the Handbook of Chemical Property Estimation Methods which describes the methods used for estimating bioconcentration factors in aquatic organisms. These methods are based on data from laboratory experiments that were designed to maintain relatively constant amounts of the chemical in the water environment, and where equilibrium concentrations of the chemical could be ascertained.

Using the above logKow figure, a BCF was derived using the Handbook of Chemical Property Estimation Methods. The BCF was found to be 8913.

The Koc for hexyl salicylate was also estimated to be 2981.This suggests that Hexyl Salicylate has a slight mobility in soil.
