What is Zeolite?

Zeolite comprises a group of hydrated aluminosilicate minerals featuring a microporous, cage-like crystalline structure derived from volcanic sediments or lab synthesis. In cosmetics, it features prominently in mattifying powders, purifying clay masks, dry shampoos, and deodorant formulations. Its high surface area and ion-exchange properties allow it to selectively adsorb excess sebum, moisture, odors, and surface debris, thereby reducing facial shine, improving powder dispersibility, and enhancing overall product stability. As an anticaking and bulking agent, it maintains powder uniformity and adds lightweight volume. Certain zeolite variants demonstrate capacity to capture reactive oxygen species, contributing mild antioxidant behavior without altering product pH significantly.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Absorbent
Absorbs water and/or sebum to reduce greasiness and shine, improve dry touch, and help keep powders and emulsions feeling lighter on skin.
Deodorant agent
Targets malodor by neutralizing odor molecules, inhibiting odor-causing microbes, or adding fragrance notes to improve underarm and body freshness.
Anticaking agent
Prevents powders from clumping by reducing moisture pickup and improving flow, keeping loose and pressed powders uniform during storage and use.
Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Deodorant
Helps control body odor by reducing odor-causing bacteria and/or neutralizing or masking malodor, without necessarily reducing sweat production.

Benefits

Absorbs sebum and impurities to promote a cleaner, less shiny appearance.

Helps control odor by neutralizing malodor molecules in deodorants.

Provides lightweight bulking and anticaking for smoother powder textures.
