About HALLOYSITE

A natural clay nanotube mineral — absorbs oil and adds texture while delivering a silky feel to skin products.

Detailed Analysis

Halloysite is a naturally occurring aluminosilicate clay mineral (kaolin group) with a distinctive nanotubular structure. It functions as an absorbent, anti-sebum agent, colorant, and viscosity controller. Its tubular morphology gives it a higher surface area than flat clays like kaolin, making it an excellent oil absorber. Halloysite has been studied for drug delivery applications. No GHS hazards or EU restrictions apply. Generally recognized as safe for topical use.
