- Is DCBS a sulfonamide accelerator?
- Soluble in acetone organic liquids, including fats and oils, insoluble in water. DCBS is a sulfonamide accelerator with excellent anti-scorching property and delayed onset of cure. It is compatible with natural and synthetic rubbers. Suitable for radial ply tyre, rubber belts and shock absorber, etc. Particularly it produces good adhesion to metal.
- Is DCBS a toxicity hazard?
- The acute toxicity of N,N-dicyclohexyl-2-benzotazothiazolesulfenamide (DCBS) is low. The oral LD50 in rats is greater than 1,000 mg/kg and the dermal LD50 in rabbits is more than 2,000 mg/kg. This chemical is moderately irritating to skin and slightly irritating to eyes but no sensitizing to skin.
- Is DCBS genotoxic in vivo?
- The weight of evidence suggests this chemical may not be genotoxic in vivo. DCBS is a white powder with a water solubility of 1.9 x 10-3 mg/L at 25 °C, a melting point of 99 °C at 1013 hPa and a vapour pressure of < 7.0 x 10-5 Pa at 100 °C.
- Does DCBS have a high bioaccumulation potential?
- DCBS is a white powder with a water solubility of 1.9 x 10-3 mg/L at 25 °C, a melting point of 99 °C at 1013 hPa and a vapour pressure of < 7.0 x 10-5 Pa at 100 °C. A measured log Kow value of >4.8 suggests that this chemical is suspected to have a high bioaccumulation potential.
