  • Is CBS a rubber accelerator?
  • Almost all rubber compounds on the market contain rubber accelerator as CBS in a wide range of products, but it is difficult to know which rubber product contain which rubber accelerants. Therefore the use of CBS in consumer product cannot be ruled out completely.
  • How much air is released from a generic rubber manufacturing site?
  • Releases to air from a generic rubber manufacturing site have been estimated according to OECD emission scenario document to be 31 kg/day expressed as unreacted CBS. It is noted, that the major part of this amount is expected to be released in form of breakdown products.
  • What is the NOAEL/reproductive organ toxicity of CBS?
  • With the assumption of hydrolysis of CBS to equimolar amounts of CHA and MBT and with molecular weights of 99.18 for CHA free base and of 264.5 for CBS these values are converted to a NOAEL/reproductive organ toxicity of 267 mg/kg bw/day (Brune et al., 1978) and 218 mg/kg bw/d (Gaunt et al., 1976) for CBS.
