Methyl Paraben vs sodium benzoate comparison as anti fungal in lotion

Abdullah

In a lotion at pH in PKa of sodium benzoate, in combination with phenoxyethanol or DMDM hydantoin, what percentage of sodium benzoate will have the same anti fungal effect as 0.2% methyl Paraben?

Use at least 2500 ppm - but parabens prob better.
