White clay is sometimes called kaolin, named after the Chinese city Kao-Ling where it was discovered. It is one of the main ingredients used in natural beauty products, naturopathy, and treating animals. It is quite common for clay plaster to be used to dress a lame horse.

White clay, which can also be harvested in France (the clay we particularly appreciate), is naturally rich in metals and due to its structure has a high absorption capacity. Its efficacy means it is often used in purifying products to capture sebum and impurities.

Rhassoul is a type of clay collected in the Moroccan Atlas Mountains, where the soil is not fertile but dry. Rhassoul requires limited intervention; it is simply dried in the sun and sometimes reduced to a fine powder to facilitate use.

In pharmaceutics and cosmetics, it is frequently used to neutralize substances or purify an environment, for example, water.

It is different from other clays due to its ability to absorb large amounts of water (1.66 times its weight), becoming a liquid paste. Ancestral Moroccan rituals have been using it for many years for its cleansing properties.

Rhassoul is often combined with floral water or argan oil to create a 100% natural mask.  Applied to the skin or hair, it captures sebum and impurities, acting as a natural mineral soap.
