Kaolins are clays with a wide range of uses, being one of them as a component in several types of cosmetics. There are not many published researches available concerning the sorption capacity of cosmetic oils in kaolins, mainly related to creams and emulsified products. This paper is focused in a commercial kaolin from the state of São Paulo, Brazil. Characterization was made using techniques such as XRD, FTIR, SEM, particle size distribution, etc. Oil sorption capacity of the kaolin was measured considering different types of oils mainly used in cosmetics formulations. Results obtained in some of the tested oil systems were superior to 150% oil absorption, on a weight basis.
