With respect to the registrant's EU supply chain MTF is only imported as
a monomer in polymers - the discreet or unreacted monomer is not
present. Residual amounts of MTF in the prepared polymers are not
significant (refer to "Monomer residue analysis" report in dossier
section 13 - residual MTF was found to be less than the analytical Limit
of Quantitation of 3 ppm).
On this basis it is considered that no exposure of MTF to the
environment may occur through the registrant's European supply chain and
therefore MTF does not present a risk to the environment.
With reference to the Regulation (EC) 1272/2008, as Adapted for
Technical Progress by Regulation (EU) 286/2011 (second ATP to CLP
Regulation), Annex 1, Table 4.1.0, MTF is classified as hazardous the
the aquatic environment. The relevant acute LC50 or EC50 values for
fish, crustacea and algae or aquatic plants are all within the range 0.1
- 1 mg/L with corresponds to a classification as Acute Category 1. With
reference to table 4.1.3 of Annex 1, the corresponding M-factor the the
acute hazard is 1.
With respect to the chronic hazard, no relevant long-term (chronic) data
are available for MTF; the chronic hazard is therefore classified with
reference to section (iii) of table 4.1.0. In the available ready
biodegradability study MTF was found not to have degraded over the
28-day test period. As noted above, the acute L(E)C50 values for fish,
crustacea and algae are all within the range 0.1 - 1 mg/L which
therefore corresponds to a classifiation in Chronic Category 1 (M-factor
The corresponding signal word for labelling is "Warning" and the Hazard
Phrase "H410: Very toxic to aquatic life with long lasting effects"
should be applied.
