Additional information
Conclusion on classification
The information concerning the aquatic toxicity of N, N-Dimethyldipropylentriamine
are summarized hereafter:Acute toxicity to fish (OECD 203 and
DIN 38412 part 15
): two studies showed that LC50 _96h is higher than 100 mg/L in Danio rerioAcute toxicity to daphnia (
ISO 6341 -1991)
: EC50_48h = 9.2 mg/L in Daphnia magnaToxicity to algae(OECD 201): ErC50 -72h = 21 mg/L and NOEC = 5.7 mg/L in Pseudokirchneriella subcapitata.
N, N-Dimethyldipropylentriamine is considered as not persistent in the environment since it is readily biodegradable.
