Ingredient review
Epoxy Resin Coated Aluminum Powder
INCI: ALUMINUM POWDER (AND) EPOXY RESIN
A metallic pigment that adds sparkle but may raise concerns for inhalation or skin sensitivity in some formulations.
In plain English
This ingredient is a fine aluminum powder coated with a thin layer of epoxy resin. It's used in makeup like eyeshadows and nail polish to create a shiny, metallic finish. The coating helps the powder stick better and last longer on the skin or nails. While generally safe on intact skin, it's not recommended for use in loose powders or sprays because inhaling aluminum particles can be harmful.

What it is
A synthetic pigment made from aluminum particles encapsulated in epoxy resin to prevent oxidation and improve cosmetic performance.
How it works
The aluminum core reflects light, giving a metallic sheen, while the epoxy coating protects the aluminum from reacting with other ingredients and helps the pigment adhere to the skin or nail surface.
