  Preservatives

  Posted by Anonymous on August 5, 2015 at 4:10 am

  Has anyone had any experiences with using potassium sorbate or absorbic acid as shampoo preservatives either? I’m making an all natural shampoo and want to avoid parabens.

  potassium sorbate works fine. Keep the pH around 5 - 5.2

  And yet another blow is struck for the anti-science crowd…

  @bobzchemist - hope I’m not too insensitive, but that comment LITERALLY made me “LOL”

  I’m perfectly fine if someone says “my customers don’t want to buy anything using parabens” - I’m in that exact situation at work myself -  but please, the “parabens are bad” claims have been thoroughly debunked.

  I think you could use sodium benzoate as well. Just be careful of the ph.
