  • How much CBS can be retained in a rubber product?
  • Taking into account that the maximum concentration of CBS in the uncured compounds is 3.5 % (technical rubber), the amount of CBS that can be retained in the finished product is limited to 0.2 %. Due to the resulting low concentration of CBS, a considerable exposure to CBS during the processing of rubber goods is not expected.
  • Does CBS affect the processing of rubber goods?
  • Due to the resulting low concentration of CBS, a considerable exposure to CBS during the processing of rubber goods is not expected. Therefore, the processing of rubber, e.g. cutting, melting, is not considered in this report. Occupational exposure limits for CBS have not been established in Western Europe and USA.
  • Is repeated dose toxicity a concern for Scenario 1 (production of CBS)?
  • With respect to systemic effects there is concern for repeated dose toxicity (inhalation) for scenario 1 (production of CBS). The lowest critical endpoint-specific exposure level is 2 mg/m3 which results from systemic effects after repeated inhalation. This level should be used as reference for establishing an occupational exposure limit.
