What is "Illite" and what is its utility?

Clays are sedimentary rocks that originate from the degradation of the parent rock. Clays vary depending on the nature of the parent rock and environmental conditions.

Illite, or green clay, primarily results from the degradation of basic magnetic rocks under the influence of a cold climate. It derives its name from the American state of Illinois, where it was first described in 1937. It is composed of three layers of phyllosilicates, a layer of aluminum (Al) surrounded by two layers of silicate (Si). It also contains other minerals such as potassium, magnesium, iron, etc.

Illite is obtained through extraction from a natural quarry, followed by a crushing and fine grinding process. No chemical reactions occur. Only a subsequent heat treatment is necessary to prevent microbial contaminations.

Thanks to its structure of separated layers with interlayer spaces (a "lamellar" structure), illite has excellent absorbent properties. It can capture impurities and bacteria present on the skin and also on the scalp... In addition, it also absorbs excess sebum. This property makes it particularly relevant for the care of oily, acne-prone skin and oily scalps.

Furthermore, the presence of mineral salts on the surface of this compound gives it a negative charge. In solution, the negative charges attract the positive ions present on the skin's surface. This ionic exchange contributes to the remineralization and detoxification of the skin.

It is also noteworthy to mention the deodorizing effectiveness of green clay. It neutralizes odors and absorbs excessive perspiration, thus justifying its inclusion in certain deodorants.
