Stability

Epoxy coatings can undergo degradation when exposed to solvents such as dimethyl ether (DME), which can lead to delamination. Alcohols and water may also compromise the integrity of epoxy-based coatings in certain formulation contexts.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) has not specifically evaluated 'Epoxy Resin Coated Aluminum Powder'. While Aluminum Powder (CAS Reg No 7429-90-5) is FDA-listed for external cosmetic use, including the eye area, the safety concern stems from the epoxy coating. Uncured epoxy resin is classified as a powerful irritant (Skin Irritant category 2, Eye Irritant category 2) and potent sensitizer (Skin Sensitizer category 1), capable of inducing severe allergic contact dermatitis. Although fully cured epoxy resin is generally considered non-irritating and non-sensitizing, the potential for measurable amounts of uncured reagents to persist significantly elevates the overall risk profile of this ingredient in cosmetic applications.

Our Assessment

Verdict

Avoid

Given its sole function as a cosmetic colorant and the significant, inherent risks associated with potential uncured epoxy resin—a known irritant and sensitizer—this ingredient is not recommended for precision skincare formulations.
