I am wanting to make liquid soap (potassium based). How much preservative is needed.?
I plan on using geography 221
Geogard 221 is typically used at 0.2 to 0.8% in both rinse-off and leave-on product formulations. The higher percent would be used if your product had a high percent of water or herbal extracts.
So the question is - Do you need to add a higher ratio of preservative to the final product (diluted)? If so, what percentage?
