EC number: 232-304-6
CAS number: 8002-26-4
A complex combination of tall oil rosin and fatty acids derived from acidulation of crude tall oil soap and including that which is further refined. Contains at least 10% rosin.
A Final Decision letter
(CCH-D-2114412576-50-01-F) was received for this substance on 09 July
2018 which requested further information on the PBT properties of the
Block 10 Aldehyde consituents in this substance. As a first step Abietal
was chosen to represent the Aldehyde Block 10 consituents and a ready
biodegradation study was comissioned and depending on the outcome of
that study the requirement for further testing for Persistence,
Bioaccumulation and Toxicity would not be required.
The results show that Abietal meets the
criteria in the OECD 301B to be labelled readily biodegradable e.g. at
least 60% biodegradation in 28 days. Meeting the 10-day window was not a
requirement according to both the ECHA Final Decision Letter and OECD
The test item is non-persistent, and
satisfies the criteria to be labelled readily biodegradable based on the
results obtained in the second experiment.
Therefore, no further work on the
persistence of DTO or its consituents is required.
