Description of key information

Waiver - 2,4,7,9-Tetramethyldec-5-yne-4,7-diol is used as a co-formulant in plant protection products.  In-field use of plant protection products can result in exposure to agricultural soil or to edge-of-field water bodies mainly as a result of spray drift (spray formulations only).Therefore, in accordance with the requirements under REACH, it is necessary to conduct risk characterisation for the potentially exposed compartments if the substance meets the criteria for classification as dangerous according to Directive 67/548/EEC or Directive 1999/45/EC, or is assessed to be a PBT or vPvB. However, it is believed that the potential for environmental effects associated with this use of 2,4,7,9-Tetramethyldec-5-yne-4,7-diol is already inherently addressed as part of the registration procedure for plant protection products under Directive 91/414/EEC.
