Additional information

Reaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenolis a solid substance, which is not soluble in water. It has some potential to absorb to soil and sediment particles.

Generally, a BCF/BAF in fish of ≥ 500 is indicative of the potential to bioconcentrate for classification purposes in accordance with CLP/GHS criteria.

The BCF/BAF values estimated forReaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenolare above the cut-off values for bioaccumulation indicating some potential to bioaccumulate in aquatic organisms.
