Occupational Exposure Limit (OEL) for Baytubes defined by Bayer MaterialScience
(Nanowerk News) Bayer MaterialScience (BMS) has recently implemented a product stewardship program to ensure the safe use of its products. Baytubes, BMS multi-wall carbon nanotubes, have also been part of this program.
The latest results of sub-chronic inhalation studies support the conclusion that Baytubes act like poorly soluble particles. Based on previous single and recent repeated inhalation studies BMS just derived an Occupational Exposure Limit (OEL). The OEL was set at 0.05 mg/m³. All relevant information are now included in the updated Safety Data Sheet and will further ensure that our customers work safely with our Baytubes.
The detailed results of the inhalation studies have been recently published in the peer-reviewed journals Inhalation Toxicology, Toxicological Sciences and Toxicology.
