Is this safe for 0-6 month old newborns to use Hydrated Silica?

🚨
NOT RECOMMENDED
Danger Score: 6 (Lower is safer)
Quick Answer: Hydrated Silica not recommended for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For newborns and babies (0–6 months), hydrated silica should be treated with caution. There isn’t strong evidence showing it’s clearly safe for very young infants, and some scientific reviews have raised concerns from animal studies and from persistence in the environment.

What to Do

When caring for a baby under 6 months, choose products specifically labeled for infants and avoid items that list hydrated silica when possible. Don’t use products with hydrated silica on broken, sore, or diaper-rash skin. If a product with this ingredient is used, do a small patch test on non-sensitive skin, stop use if you see redness, swelling, or a rash, and check with your pediatrician.

⚠️Warnings

Avoid using hydrated silica in leave-on baby products and on irritated or broken skin. Watch for signs of irritation (redness, rash, swelling). Note that Cosmetic Ingredient Review has reported animal tumor findings in some studies, and Environment Canada and the U.S. National Library of Medicine list concerns about persistence and accumulation—these are the sources behind the caution. Some product-safety programs also restrict this ingredient unless manufacturers provide extra safety evidence.

Safety Risk Labels

This ingredient has the following documented risks:

Cancer: Animal studies reported tumor formation at low doses, according to the Cosmetic Ingredient Review. That means there is some evidence from lab animals that this ingredient can cause tumors under certain conditions.
Builds Up: Records from the U.S. National Library of Medicine list this ingredient as persistent and bioaccumulative in wildlife and humans, and the ingredient profile flags high persistence. That means it can accumulate in bodies and the environment over time.
Absorbed: The ingredient summary notes enhanced skin absorption, and the Cosmetic Ingredient Review flagged data gaps in safety assessments. This signals a chance the material can get through skin and into the body more easily than expected.
Banned: This ingredient is restricted in some product standards and cannot be used in certain verified products without clear safety proof; industry guidance (Cosmetic Ingredient Review) also recommends limits. That means some regulators or standards bodies limit its use.
Environmental: The U.S. National Library of Medicine and the ingredient profile identify persistence and bioaccumulation in wildlife, indicating a real potential for long-term environmental harm.
