Using Bentonite Clay with Herbal Powder for Scrub

Regarding your question about making a herbal powder scrub with a ratio of approximately 70% Bentonite and 30% herbal powder:

Based on the information available, Bentonite clay can be used in formulations at concentrations ranging from 1% to 100%. Therefore, using Bentonite at 70% in your mixture is acceptable in terms of the Bentonite concentration itself.

However, the overall safety and suitability of your herbal powder scrub formulation will depend on the specific herbal powder you are using, its properties, and how it has been processed. The staff's response indicates that the suitability of the formula relies on the herbal powder, not the Bentonite.
