Use of Natural Halloysite as a Functional Cosmetics Carrier
Correspondence to : aumsuh@kigam.re.kr
Abstract
Natural halloysite is mostly found in the form of a tubular structure with a 15–125 nm internal lumen. This kaolin clay can be used for encapsulating a liquid ingredient of cosmetics and for immobilizing an inorganic solid-phase ingredient. In this paper, the encapsulation and immobilization procedures are introduced and two example applications are reviewed to demonstrate the usefulness of halloysite as a cosmetics carrier. It may help attract more interest in cosmetic applications of halloysite and thus spur more research on the utilization of natural clays.
