Description of key information

The log Kow value of Benzyl acetate was found to be 1.96 (Sangster, 1989). The log Kow is below the trigger of 3 therefore the substance is not expected to bioaccumulate in living organisms. According to Column 2 of Annex IX of the REACH regulation, no bioaccumulation study is required if the log Kow is below the trigger of 3.

However, 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 log Kow figure, a BCF was derived using the Handbook of Chemical Property Estimation Methods.The BCF was found to be 8. According to the guidance on information requirements and chemical safety assessment part B, Benzyl acetate is not considered to be hazardous as the BCF is below 10.
