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.
Biodegradation: 73.2% in 28 days (OECD 301F).
the purposes of modelling the fate of each constituents block in waste
water treatment plant, a standard biodegradation rating for individual
constituents was assigned on the basis of the BIOWIN score and expert
judgement. As far as possible, the constituents allocated to each
hydrocarbon block had the same BIOWIN-based biodegradation rating.
However, to avoid use of too many blocks, and to ensure that the range
of log Kow values within individual blocks was not excessive,
in some cases RB10 and RBN and also INHN and INHY constituents were
grouped together. Where this was necessary, the overall degradation
rating for the block was assigned on a case-by-case basis, taking into
account the rating for the most abundant constituent(s) in the block.
