Description of key information
Additional information
Reaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenol is a non volatile, poor soluble in water, solid substance. The estimated QSARs data on environmental degradation of Reaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenol are summarized in table below. Overall, the QSAR estimated data suggest that this substance will not degrade fast in the environment.
Table. Degradation rates ofReaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenol
Degradation rate in water: |
Abiotic transformation: Hydrolysis is not a relevant degradation route for the substance.
Biotic transformation: DT50=37.5 days (900 hours) |
Degradation rate in sediment: |
DT50=337.5 days (8100 hours) |
Degradation rate in soil: |
DT50=75 days (1800 hours) |
Degradation rate in air: |
DT50=0.585 days
