✦ Synopsis

The solubility features of a homologous series of alkyl phydroxybenzoates (parabens) with alkyl groups, in an ascending order from methyl to n-butyl, were investigated together with benzyl paraben and methyl p-methoxybenzoate. A phenomenon of mutual solubilizing potential was observed to exist when the solubility of a mixture of an alkyl paraben and benzyl paraben in 60 % polyethylene glycol 4Wwater was examined. The analysis was carried out by means of UV spectrophotometry and NMR spectroscopy. The 1 Supplied by Matheson Coleman & Bell.
