Additional information
Maleic acid logKow = -0.48 (Sangster, 1994)
Phthalic acid logKow = 0.73 (Hansch et al., 1995)
Fumaric acid logKow = 0.46 (Hansch et al., 1995)
Benzoic acid logKow = 1.87 (Hansch et al., 1995)
Citraconic acid logKow = 0.60 (estimation KOWWIN v1.67)
All these values are well below logKow = 4 that triggers classification for bioconcentration according to CLP regulation
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
