text: Investigations have also been conducted with a homologous series of the methyl, ethyl, propyl and butyl esters (15; the parabens) of 4-hydroxybenzoic acid  and with the phenolics, phenol (16), cresol (17) and chlorocresol (18)  on the basis of which the following conclusions have been reached: (i) activity increases in the paraben series in the order Me, Et, Pr and Bu ester, but this is accompanied by a corresponding decrease in aqueous solubility; (ii) wild-type strains of E.coli and Salmonella typhimurium are intrinsically more susceptible to parabens than rough and especially deep rough mutants; (iii) the greatest effect in the paraben series is shown by the Bu ester against the deep rough strains; (iv) in the phenolic series, phenol is the least active, chlorocresol (4-chloro-3-methyl phenol) the most active, and the greatest effect is shown by chlorocresol against the deep rough strains.
