Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Description of key information

Based on the biodegradation study (OECD TG 301F-Manometric Respirometry Test), Pentyl propionate is considered to be readily biodegradable.

Additional information

There are two biodegradation studies available. In a GLP study conducted according to OECD TG 301F (Manometric Respirometry Test), biodegradation of pentyl propionate began soon after addition to the test mixtures, and after 28 days reached 90.1 ± 6.5% (mean ± 1 SD) based on biological oxygen demand (BOD) and exceeded 60% biodegradation within 5.9 days of the start of the test and within the 10-day window detailed in OECD 301F. The results of this test demonstrated that Pentyl Propionate can be classified as “readily biodegradable”, according to the OECD 301F: Manometric Respirometry Test.

A supporting study followed the procedures outlined in Standard Methods for the Examination of Water and Wastewater, 16th Ed., American Public Health Association. This study determined there was 84% biodegradation of the material by Day 10 and 97% biodegradation by Day 20. This offers supporting evidence that the material is readily biodegradable.

Biodegradation tests for sediment simulation testing, ultimate degradation in surface water simulation testing, and soil simulation testing were not performed as these tests are not needed because the substance was determined to be readily biodegradable.
