For babies 0–6 months old (newborns, infants) this ingredient is best avoided when possible. It can make skin more likely to absorb other substances and has been linked to some cases of contact allergy. Overall health risks are low in adults, but infants have thinner, more absorbent skin, so we are more cautious.
If you care for a newborn or infant, choose products labeled for babies that do not list isopropyl myristate when possible. Do not use creams or lotions with this ingredient on broken skin or large surface areas of an infant. If a product with it is already in use, watch the skin closely for any redness, rash, or swelling and stop use if these appear. For any concerning reaction, contact your pediatrician.
Watch for signs of skin reaction (redness, rash, itching, swelling). The warning comes from published human case reports of contact dermatitis and a lab study showing the ingredient can increase skin absorption (see studies on penetration enhancement and contact allergy). Also note that regulatory reviews (Environment Canada) state it is not expected to be systemically toxic, but those findings are from adult-focused data, not infant-specific tests.
