All components show low octanol/water partition coefficient

Key value for chemical safety assessment

at the temperature of:
20 °C

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
