Is this safe for 0-6 month old newborns to use Magnesium Hydroxide?

YES - Generally Safe
Danger Score: 2 (Lower is safer)
Quick Answer: Magnesium Hydroxide is generally considered safe for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For infants (0-6 months), magnesium hydroxide is generally low risk when used in a product made for babies. However, babies have very delicate skin, so we are a little more careful than with adults.

What to Do

Choose products specifically labeled for babies or newborns. Avoid any product that lists “nanopowder,” “nano,” or is a loose powder. Don’t put products with this ingredient near your baby’s eyes, mouth or on broken skin. Apply a small amount first and watch the area for redness, swelling, increased fussiness, or rash. If you see any of those signs, stop using the product and check with your pediatrician.

⚠️Warnings

Some official reviews note limited evidence of skin, eye or breathing irritation (European Chemicals Agency). Industry safety panels say the ingredient is safe when formulas avoid irritation (Cosmetic Ingredient Review). Independent sources flag potential concerns if the ingredient is present as a nano-sized powder. Also, some product-verification programs require extra safety data before allowing this ingredient in verified baby products. Because of these findings, avoid powdered or nano forms and stop use if your baby shows irritation; consult your child’s doctor for persistent problems.

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.
