What is special about kaolinite clay? Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar.
Kaolin clay is enriched with kaolinite mineral that is ideal for all skin types. Even people with sensitive skin can use it. Bentonite is also a naturally forming clay found in cosmetics [4]. But it's mostly suitable for people with oily skin. Kaolin clay doesn't strip away the natural oil from your skin. It only removes the extra sebum oil.

Density functional modeling of the crystalline layered aluminosilicate mineral kaolinite is conducted, first to reconcile discrepancies in the literature regarding the exact geometry of the inner and inner surface hydroxyl groups, and second to investigate the performance of selected exchange-correl ….
Kaolinite is derived from the commonly used name kaolin, which is a corruption of the Chinese Gaoling (Pinyin; Wade-Giles romanization Kao-ling), meaning "high ridge," the name of a hill near Jingdezhen where the …
Kaolinite is described as a 1:1 clay mineral consisting of two layers joined through an apical oxygen. One layer is known as the siloxane layer and consists of silicon tetrahedra joined in an hexagonal array. This layer is coupled to a gibbsite-like layer consisting of octahedral aluminium bonded to four OH units and two oxygen atoms.
Kaolinite (Kaolinite). Kaolinite played an important part in early human civilization, providing the raw material for tiles, bricks, and pottery. While the soft clay is the main component of china and porcelain, kaolinite has numerous other applications, often used in agriculture, as well as for making paints, ceramics, rubber, and paper.
Near-infrared spectrum of kaolinite is characterized by absorptions in the regions around 7000 cm −1 (1.4 µm) and 4500 cm −1 (2.2 µm) related to Al 2-OH vibrations, forming the so-called "1.4 and 2.2 µm doublets" [unless specified, all the details about NIR spectral signature of kaolinite are taken from Madejová et al.
