Details on results:
The water solubility of Santoflex 14 in pH 7.0 deionized water is 0.67 mg/l.

Though there is no prescription requirement of water solubility in case of rapid hydrolysis, the chosen method (Extraction Method) is suitable for instable substances and therefore this study is used for assesement.

Conclusions:
Interpretation of results: slightly soluble (0.1-100 mg/L)
The water solubility of N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine is 0.67 mg/L at pH 7 and 25°C. (Monsanto, 1986). However this result is of theoretical interest as the substance hydrolyses rapidly with a half life of about 5 hours.
Executive summary:

The water solubility of N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine is 0.67 mg/L at pH 7 and 25 °C.
