Kids Clear™ is a 100% pure pharmaceutical grade bentonite clay that has a very high cation exchange capacity (a 98-107 meq/100g on the CEC scale), which means it has a very high ionic surface charge when mixed with warm water. The Kids Clear™ Detoxifying Clay Baths not only draw out chemical toxins and pollutants from the body, it also assists in pulling out heavy metals like mercury, cadmium, arsenic, aluminum, copper and lead.
