EC number: 205-749-9
CAS number: 149-91-7
Experimental WS (% w/w)
Calculated WS (%w/w)
The water solubility of gallic acid has been measured using UV/vis
spectrophotometer as 1.516%w/w at 24.85°C.
Experimental WS (g/L)
26.4 (& 22.5*)
measured by gravimetry
The water solubility of gallic acid has been measured by UV
spectrophotometry and calculated as 14.7 g/L at 24.85°C.
The water solubility of gallic acid has been measured by HPLC as 13.0
g/L at 24.85°C.
weight of evidence approach applies to the publications of Daneshfar A.
et al (2008), Motta F.L. et al. (2008) and Srinivas et al. (2010) and in
handbooks of Yalkowsky & Dannenfelser (1992) and Budavari (1996).
weight of evidence approach is justified as determined from more than
one piece of information (independent sources). We claim the
reliability, relevance, adequacy and quality of the weight of evidence:
Klimisch score of 2 is assigned to the studies
of test material: substance purity ranges from ≥97% (Srinivas et
al.,2010), ≥98% (Mota et al., 2008) to 99.5% (dried gallic acid
monohydrate) without affecting the reproducibility of the endpoint
of test method and conditions: the tested methods are described in the 3
of the endpoint: the values obtained from independent sources show a
the endpoints, whereas obtained from not internationally approved test
guideline, with different sources and purity of test item lead to a
clear trend: solubility of 13.0-15.16
24.85°C and 11.4 -11.9 g/L at 20°C.
