MICA (Mica (CI 77019)) – function in cosmetics

A mineral pigment that adds shimmer and slip.

What it is

Mica is a naturally occurring silicate mineral ground into thin, flat particles. It reflects light, giving a pearly or shimmering effect, and improves how powders spread; it is often coated with titanium dioxide or iron oxides.

Where it is used

Found in eyeshadows, highlighters, powders, lipsticks and shimmering body products.

Limits of interpretation

The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.

The INCI name does not show where the mica was mined; responsible sourcing is a supply-chain question the label cannot answer.

Functions

Anticaking

Preventing agglomeration of particulate solids into lumps or hard masses (cohesive cake), thus allowing free flow of particles.

Bulking

Non-reactive (chemically inert), solid ingredients that dilute other solids and/or increase the volume of cosmetic products.

Colorant

Exclusively or mainly intended to colour the cosmetic product, the body as a whole or certain parts thereof, by absorption or reflection of visible light; (precursors of oxidative hair colorants shall be deemed colorants). All authorised colorants are substances in the positive list of Annex IV to the Cosmetics Regulation 1223/2009.
