This substance is identified by SDA Substance Name: C16-C18 and C18 unsaturated alkyl carboxylic acid methyl ester and SDA Reporting Number: 11-010-00.
Waiving based on exposure and Chemical Safety Assessment
According to Column 2 of REACH annex X the
test if the results of the chemical safety assessment indicates no need
to investigate further the effects of the substance and/or relevant
degradation products on sediment organisms.
The substance is very poorly soluble in
water and readily biodegradable. The equilibrium partitioning method,
following a fugacity model III indicate a partition of the substance on
sediments of 85.5%, based on high Kow.
But based on results of bacteria
inhibition and biodegradability, it is not previewd a toxicity effect on
A tier 1 Risk Assessment based on the
European main use of the substance elaborated with EUSES 2.0 showed no
concern; it is assumed that water exposure will not occur because the
exposure scenarios is focused only on industrial application where all
waste, when present, is sent to STP, where a 100% of degradation occurs.
(See annex in the "Long term toxicity to fish" end point summary)
