Safety Risk Labels

This ingredient has the following documented risks:

Organ Risk: A European chemical regulator (ECHA) has classified magnesium hydroxide as toxic or harmful for non-reproductive organs in some assessments. That means, in certain situations or at higher exposures, it could hurt organs such as the liver, kidneys, or lungs.
Irritant: Reviews by a European chemical agency (ECHA) and a cosmetic safety panel (CIR) report limited evidence that magnesium hydroxide can irritate skin, eyes, or the respiratory tract, and animal studies show eye irritation at high doses. This can cause redness, stinging, tearing, or coughing in sensitive people.
Absorbed: Nano-focused sources note nanoparticle forms and warn that nano-scale materials may absorb through skin. Supplier notes also list nanopowder forms of magnesium hydroxide, so those forms could enter the body through the skin more easily than larger particles.
Asthma: The same ECHA and cosmetic industry assessments mention limited evidence of respiratory irritation. If inhaled or if it causes lung irritation, magnesium hydroxide could make breathing problems or asthma worse in some children.
Immune system: A European chemical review (ECHA) found limited evidence of skin toxicity or allergic reactions. That suggests some people could have immune or allergic skin responses, like rashes or contact sensitivity.
