Is this safe for 0-6 month old newborns to use Hydrogenated Polyisobutene?

YES - Generally Safe
Danger Score: 2 (Lower is safer)
Quick Answer: Hydrogenated Polyisobutene is generally considered safe 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: this ingredient is commonly used as a skin moisturizer and is viewed as low risk in adults. Because baby skin is thinner and more sensitive, it should be used with caution. In small amounts in products made for infants it is generally okay, but avoid routine heavy use on very young babies.

What to Do

Choose products specifically labeled for infants or newborns. If a product contains this ingredient, use a small amount and avoid applying it to very large areas every day. Do a simple patch test on a small area (for example, the forearm) and wait 24 hours to watch for any redness or irritation. Do not use on broken or inflamed skin. If your baby has eczema, very sensitive skin, or was born prematurely, talk with your pediatrician before use.

⚠️Warnings

Stop use and contact your pediatrician if you see redness, swelling, rash, or other signs of irritation. Note there are industry notes about safe concentration limits and some data gaps (Cosmetic Ingredient Review - CIR) and a European agency has reported possible non-reproductive organ toxicity in some assessments (European Chemicals Agency - ECHA). Because of these notes and the limited infant-specific testing, avoid heavy or daily use on newborns and do not apply to open or damaged skin.
