Help me understand, please. I understood your consideration that the product was “self-preserving” - why did you think that possible? Is there unique chemistry?

Be aware the preservative test evaluates speed and extent of kill, not growth inhibition.

Yes its good no irritation but i need to send a chalange test to make sure that E leen green B(pentylene glycol, sodioum benzoate and benzoic acid) is effective against fungal and microbs. Thanks PhilGeis for your support i appreciate that.

Thanks zetein - one is in a pump and surfactants as raw materials are often also preserved . Combination wth sufactants does effectively increase pKa - still, good luck with those.

Hello, I have formulated a micellar water, but I have a problem, when I raise the ph to 5.5, the solution becomes cloudy. How do I fix this problem?

  You can create a new discussion and write your formula too so we can see what is the problem.
