❌KAOLIN CLAY

The main constituent of Kaolin is Kaolinite. Kaolin clay can potentially be risky to the eyes, skin, stomach, and open wounds. 

CDC lists it as potentially toxic to inhalation, skin, and/or eye contact with these side effects: Chronic pulmonary fibrosis, and stomach granuloma.

Plus Kaolin is used as a pesticide and it is associated with lead and other heavy metals. Read here
