Kaolin is a naturally occurring, purified white clay used as an adsorbent, diluent, and protective agent in pharmaceutical and cosmetic formulations.
In oral products, it has historically been used as an adsorbent for mild gastrointestinal discomfort, often in combination with pectin or other actives.
In topical preparations, kaolin provides coverage, oil absorption, and a smooth texture, making it suitable for masks, powders, and dermatological pastes.
Its fine particle size, chemical inertness, and good suspension properties also make it useful as a filler in tablets and as a rheology modifier.
Pharmacopeial grades are carefully controlled for purity, heavy metals, and microbiological quality.
