Carbon Black Content for Medical-Grade Coatings
Carbon Black Content for Medical-Grade Coatings
(OP)
Hi.
Anyone know permissible carbon black levels for use in medical-grade, non-implantable coatings?
Any empirical data available with respect to cytotoxicity?
Thanks!

RE: Carbon Black Content for Medical-Grade Coatings
Anyone else interested? I've found my answer.
While carbon black was reclassified 'Group 2B' some time ago, the route of entry was inhalation (by rats).
To be classified a carcinogen or reproductive toxin, by OEHHA'a own definition, carbon black must meet the following criteria:
1) airborne
2) unbound
3) respirable size
But, within polymeric films (coatings), carbon black is encapsulated. ..."Exposure to carbon black, per se, does not occur when it remains bound within a product matrix, such as rubber, ink, or paint."
