Administrative data

long-term toxicity to aquatic invertebrates
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
Justification for type of information:
n-butyl propionate is readily biodegradable and has a low potential for bioaccumulation (log Kow =2.67). The risk characterization shows that the PEC/PNEC ratio for freshwater is clearly <1 with a PNEC derived with acute data on three trophic levels. According to REACH Annex IX column 2, testing of chronic effects on invertebrates can be waived for n-butyl propionate.
