NOEC, Ceriodaphnia dubia (water flea), semi-static test, 7 d, number of offspring, 13,020 mg/l
Dipotassium hydrogen phosphate
Acute toxicity to fish
Material is practically non-toxic to aquatic organisms on an acute basis
(LC50/EC50/EL50/LL50 >100 mg/L in the most sensitive species tested).
LC50, Leuciscus idus (Golden orfe), static test, 48 Hour, > 900 mg/l, Method Not Specified.
Persistence and degradability
Propylene glycol
Biodegradability: Material is readily biodegradable. Passes OECD test(s) for ready
biodegradability. Biodegradation may occur under anaerobic conditions (in the absence of
oxygen).

Dipotassium hydrogen phosphate
Biodegradability: Biodegradation is not applicable.
Bioaccumulative potential
Propylene glycol
Bioaccumulation: Bioconcentration potential is low (BCF < 100 or Log Pow < 3).
Partition coefficient: n-octanol/water(log Pow): -1.07 Measured
Bioconcentration factor (BCF): 0.09 Estimated.
Dipotassium hydrogen phosphate
Bioaccumulation: No bioconcentration is expected because of the relatively high water
solubility.
