The ingredient narratives reshaping clean beauty.

Kaolin

aka china clay · hydrated aluminum silicate · kaolin clay

A naturally occurring clay mineral used as a mattifying and stabilising agent in colour cosmetics. One of the foundational clean-beauty powder ingredients.

Benefits
  • Oil absorbent — mattifying effect
  • Stabilises emulsions and suspensions
  • Improves texture in powder formulas
  • Mild skin conditioning
  • Natural mineral — minimally processed
Example uses
  • Bronzing crèmes
  • Setting powders
  • Clay face masks
  • Mattifying primers
  • Talc-free foundations
Formulation notes

Fine particle size (1–2 microns typical) required for cosmetic use. Functions in both anhydrous powder formulas and emulsions. Opaque white — colour management in tinted products.

Watchouts

Contamination risk: naturally occurring kaolin deposits can contain asbestos (tremolite) co-contamination. Cosmetic-grade kaolin must be certified asbestos-free. This distinction is critical given the talc/asbestos controversy.

Clean beauty perception

Universally accepted in clean beauty as a natural clay mineral. The asbestos contamination risk in natural clays requires supply chain vigilance that is not always communicated to consumers.
