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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
Any other information on results incl. tables
Instance: If one assumes a one hour skin contact (assuming T = 37°C and intimate
contact) with 1 dm2 of a PMMA polymer of any thickness and having 1% MMA as an
initial concentration, then the maximum possible migration (assuming complete
MMA uptake through the skin) is estimated to be approx. 4.5 µg for WP = 1 and
14 µg for WP = 0.99 conditions. In relation to the maximum possible migration,
even these overexaggerating assumptions lead to relative migrations as low as
between 0.0004% and 0.0012% of maximum possible migration in case of a 0.1 mm
thick PMMA layer. For thicker layers, for lower CP,0 values and in real life
(where only a fraction of the total MMA uptake can occur) the relative
migration would be one to several orders of magnitude lower.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
