Description of key information
log Pow range = 5.63 - 36.44 (QSAR)
Key value for chemical safety assessment
Additional information
The log Pow of the substance Glycerides, C16-18 and C18-unsatd. mono- and di-, citrates (CAS 91052-16-3) was determined by QSAR calculation with KOWWIN v1.68.
The log Pow results for the six constituents of the substance cover a range of values:
Monoglyceride (1)/C16:0 fatty acid component = 5.63
Diglyceride (1)/C16:0 fatty acid component = 10.10
Monoglyceride (3), Citric acid/C18:2 fatty acid component = 18.50
Monoglyceride (2), Citric acid/C18:2 fatty acid component = 11.80
Monoglyceride (1), Diglyceride (2), Citric acid/C18:1 fatty acid component = 36.44
Diglyceride (2), Citric acid/C18:1 fatty acid component = 29.44
No exact temperature and pH are given; it is assumed that the results correspond to room temperature and neutral range of pH.
