Results and discussion
Any other information on results incl. tables
The low PAH amounts that were extractable with toluene from cured rubber compounds (containing 30% carbon black) suggest that the PAHs become part of the network formed during the vulcanizat ion process.
The sum of 8 EU priority PAHs that migrated into toluene from uncured and cured rubbe r compounds was low (total immersion, 168h at 30°C). For uncured compounds the total 8 EU PAH were less than 2 mg/L (ppm); from cured compounds it was less than 0.05 mg/L (ppm); migration of PAHs from uncured and cured rubber samples into artificial sweat, saliva and water was below the limit of quantification.
Applicant's summary and conclusion
- Conclusions:
- Migration of PAHs from uncured and cured rubber samples into artificial sweat, saliva and water was below the limit of quantification.

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.
