CAS number: 54381-16-7
Taking into account the lack of biodegradation in a ready biodegradation
test and in a simulation test, the substance
(p-ammoniophenyl)bis(2-hydroxyethyl)ammonium sulphate is considered as
persistent or very persistent. Its log Kow is -2.8, and on the basis of
this low log Kow, it is considered as not Bioaccumulable or Very
Bioaccumulable. The chronic toxicity data assessed on daphnia
(reproduction test) and on algae (inhibition of the growth) are higher
than 0.1 mg/L and the acute toxicity on fish is higher than 1 mg/L. The
substance is neither classified as carcinogenic (cat. 1A or 1B), nor
germ cell mutagenic (Cat. 1A or 1B), nor toxic for the reproduction
(cat. 1A, 1B or 2). It is not classified as “Specific Target Organ
Toxicity Repeated Exposure category 1 or 2”. So it is considered as not
Toxic. The substance (p-ammoniophenyl)bis(2-hydroxyethyl)ammonium
sulphate is P/vP, however it is neither B/vB, nor Toxic. Therefore
(p-ammoniophenyl)bis(2-hydroxyethyl)ammonium sulphate is Not PBT and Not
Based on its physical-chemical properties, which are a very high water
solubility (178 g/L), a vapor pressure ≤ 65 Pa , a log Kow of -2.8 and a
log Koc of 0.63, the substance (p-ammoniophenyl)bis(2-hydroxyethyl)
ammonium sulphate will be found mainly in the aquatic environment when
released to the environment.
