    My guess (and a guess is as good as it gets) is the following order of happiness where all will be happy, just to a different degree: mould > yeast > Gram - > Gram +.

    So Gram negative is the biggest enemy in SLES/CAPB shampoo and mould in lotion.

    @PhilGeis preserved. My point was to blend preservative that is strongest against which organisms.

    I see. You need preservation that is strong against each of the bugs.
