    I have a question, I am using different preservative that are use to kill bacteria in the product, does it act like an antibacterial product on the skin as well ? or we have to increase the portion of it ? or it can not be use as an antibacterial agent ??

    No, preservatives in formulas are not adequate to be antibacterial on the surface of skin. You can’t simply increase the level of the preservative either. There are specific regulations as to what can be used as an antibacterial agent.

    It would be a good idea if you were to give us at least basic information such as what your product is and what it is intended to do.

    Nothing wrong with that, it’s overkill though. A hand wash is fine at pH=5 and potassium sorbate (or sodium benzoate) will be perfectly adequate to preserve it, alone. Or just use methylparaben by itself.

    @Belassi right yes but my concern was that can it be used as an antibacterial for skin as well like chloroxylenol.

    Curious… Are there studies to show how the preservatives in cosmetics interact with the microbiome of the skin?

    Can anybody tell me how much of the Benzalkonium chloride or Chloroxylenol should be use in the hand wash ? I think it should not be more than 0.07%
