What amount of caprylhydroxamic acid+0.5% phenoxyethanol will have the same anti fungal effect as 0.2% methyl Paraben+0.1% Propyl Paraben+0.5% phenoxyethanol in an emulsion?

    It is formula dependent - but doubt there are enough data to answer esp. as testing offers qualitative rather than quantitative assessment..    Think 0.3-0.5% for Capryl hydroxamic acid.
