Summary
The surface activity of vinyl stearate has provided a method for determining its solubility in water to be 0,7±0,2×10−6 mole/litre. The methods described above could be used to determine the solubility in water of any sparingly soluble surface active compound, such as stearic acid or cetyl alcohol, which formed a stable monolayer at theA/W interface. Method A could be used for compounds with a solubility as low as 10−5 mole/litre where as for Method B solubilities as low as 10−7 mole/litre could be measured.
