  Incorporating liquid germall plus into anhydrous product

  Posted by JonahRay on January 1, 2023 at 9:21 pm

  Hi there!

  I’m looking to add a bit of preservation to an anhydrous cleansing balm formula I’m working on. The issue I’m having is liquid germall plus (Propylene Glycol (and) Diazolidinyl Urea (and) Iodopropynyl Butylcarbamate) doesn’t seem to want to incorporate and just floats around.

  I was thinking since there is a good amount of emulsifier (sorbeth-30 tetraoleate) that even 0.25% would blend right in… Does anyone have any insight or other suggestions for preservatives to use (no phenoxyethanol and no weird plant extracts).

  Thanks!

  Can you say more about the product and the micro risk you’re trying to control?

  Hi @PhilGeis, it’s an anhydrous cleansing balm. It will be packaged in a jar so there is a potential for water to be introduced.

  I understand and appreciate your objective.   It’s a tough one as passive water in open pots/jars has always deviled in use-micro.

  @JonahRay, howzabout PCMX, aka chlorxylenol? Lipid-soluble and controls molds, fungi, most bacteria. Works for me.
