Description of key information

Data waiver as study would be scientifically unjustified:
PTBBA does not have any functional groups which facilitate hydrolysis of the substance. No
data on photodegradation in water were available. The abiotic degradation rate in water is assumed to be zero. (see also p. 16, EU risk assessment report (2009))
