Aluminum/Magnesium Hydroxide Stearate

What Aluminum/Magnesium Hydroxide Stearate is & what it does

Aluminum is a lightweight metallic element that appears in cosmetics in several forms, most often as compounds rather than the pure metal. In skincare and sunscreen formulas aluminum-based ingredients can act as pigments (when coated on micas), opacifiers, or carriers for color. On an INCI list, the plain entry usually points to aluminum used in colorant or pigment systems rather than as an antiperspirant active.
