A 28-day ready biodegradability was carried out with hexyl acetate according to OECD 301 D. After 28 days the test substance was found to be 66% degraded. However the 10-day window was not achieved. As such the test substance falls into the category of 'readily biodegradable, but failing 10-day window'.

An inherent biodegradability study was also conducted for hexyl acetate by a manometric respirometry test according to OECD guideline 302 C. The test substance was found to be 85% degraded after 14 days. As such the substance can be classified as inherently biodegradable.

Simulation testing for soil and sediment is not considered as the substance has been shown to be inherently biodegradable and exposure to soil and sediment is considered unlikely. Further to this the substance has been shown to be readily biodegradable but failing the 10 -day window.
