In Cosmetics, talc is compounded into products which are not absorbed by the human body. Thus, talc of high chemical purity, more than 99%, (free from Asbestos and Biminerals) is preferred.
Talc ore is ground to a semi fine powder to produce and maintain the right size and shape spectrum and controlled particle size distribution thus avoiding the clogging of skin pores and thereby maintaining normal body functions of perspiration etc.
Talc products Besta and Finex, maintain lubricity to skin over a longer period because of their high purity and platy particle shape. Talc also imparts softness and high perfume retention.
