Problem with plants extracts base on propylene glycol
Hello, I have a problem with a natural shampoo formula containing about 7% of aqueous plant extracts containing propylene glycol. A thick shampoo containing about 30% of active surfactants and about 1% of xanthan gum, when added, becomes thinner very quickly and it is not possible to thicken it with salt. Thanks in advance for your help.

Cut down the plant extracts to 1% or less. They’re not functioning in the product anyway
