  Anhydrous formula question about preservation

  Posted by Climatechangeanxiety on May 4, 2021 at 4:55 pm

  Hi! 

  So I have about 33% guar gum in my anhydrous shampoo (in addition to all my other surfs, etc). Is that bad? Let’s say it gets wet in the shower…will stuff start growing? I am using Benzyl Alchohol + DHA + a bit of KaSorbate as preservatives but afraid it’s not enough.

  This sounds like a solid product?

  hi! Yes it is a solid product. I know people say solid products don’t need preservatives but I mean…I’m got a lot of guar gum in mine…

  I actually don’t understand why people say bars don’t need preservatives?? That stuff gets wet all the time!

  Of course it gets wet - that doesn’t mean you need to preserve a film of water.  You can’t preserve water pools around the bar,.  Think your wasting your money on preservation.  
  Does the get get mushy?
