Kaolin er en sædvanligvis hvid eller hvidlig bjergart domineret af ler og med lavt jernindhold. Kaolinit er det dominerende mineral i de fleste kaoliner. De største forekomster findes i Cornwall, Georgia og South Carolina, USA. Kaolin bruges endvidere synonymt med kaolinit som fællesbetegnelse for alle tolags dioktaedriske silikater. Disse opdeles i …

Kaolin's main component, kaolinite, is a white, powdery mineral that does not absorb water. Along with kaolinite, kaolin clay also contains other minerals, such as feldspar, muscovite, and quartz.

Kaolin clay is also used to help bulk out product, act as a mild preservative and improve the longevity of powdered cosmetics. Kaolin, also known as China clay, is a naturally occurring porous soft clay that is rich in the mineral, kaolinite. Both are given their names from 'Kaoling' which is the hill where it was first mined.
