Additional information

Tripropylene glycol n-butyl ether highers is readily biodegradable. According to REACH Annex IX requirements, water and sediment simulation tests shall only be considered for substances with a high potential for adsorption to sediment. Further, the study does not need to be conducted if the substance is readily biodegradable. Because TPnB highers is readily biodegradable and has low potential for adsorption to sediments, a simulation test in water and sediment can be waived.
