What it is
Zeolite is a class of crystalline aluminosilicate minerals with a porous, cage-like structure that gives it a high capacity to absorb liquids and odors. In cosmetic formulas it is used as an absorbent and bulking agent, helping to control oil, mattify, and modify the texture and feel of the product. In sunscreens it can contribute to a less greasy, more powdery finish.
Safety & warnings
Zeolite is an inert mineral powder generally well tolerated on skin. As with other fine mineral powders, care to avoid inhalation during manufacture and use is sensible. It is not associated with notable comedogenicity at typical use levels.
Origin & sourcing
Natural or synthetic; zeolites occur as natural minerals and are also manufactured synthetically, both consisting of aluminosilicate frameworks.
