Description of key information

Additional information

Information is available for the ready biodegradability, inherent biodegradability and adsorption coefficient of hexyl acetate. A QSAR was also conducted to estimate the bioconcentration factor (BCF).

In an OECD 301D test hexyl acetate was found to be 66% degraded within 28 days, however, it did not meet the 10 -day window and is considered to be 'readily biodegradable but failing 10 -day window'. A further study on inherent biodegradability is available, conducted to OECD 302C. As the substance was 85% degraded within the 28 days, it is also considered to be inherently biodegradable.

The adsorption coefficient of hexyl acetate was determined in an OECD 121 HPLC test. The log Koc was determined to be 2.47 (Koc= 293).

A QSAR for bioconcentration carried out using the experimental log Kow estimated a log BCF of 1.844 (BCF=69.88 L/kg wet-wt) indicating a low potential for bioaccumulation.
