Preservative for Herbal Shampoo

MissCMissC Member
Hello, Can someone please recommend a preservative that I can use to extend the life of my herbal infused shampoo? I am using fenugreek and hibiscus leaves infused in water. I am also using Coco Glucoside and Betaine Will Liquid Germall plus be sufficient?

  • Its hard to say what is most sufficient. Even if someone recommends one its important to have a preservative efficacy test performed.
