Key value for chemical safety assessment

Additional information

N-[3-(trimethoxysilyl)propyl]butylamine hydrolyses in contact with water to the corresponding 3-(N-butylamino)propylsilanetriol, which have low log Kow values (<3) and thus have low potential for bioaccumulation. Therefore, in accordance with Column 2 of REACH Annex IX, a bioaccumulation study does not need to be conducted for the silanol hydrolysis products.
