For infants aged 6–12 months, potassium sorbate is a common preservative and is usually safe in small amounts, but it can sometimes cause skin irritation or an allergic skin reaction.
Use baby-formulated products that list ingredients clearly. Before using a new product on your baby (infant), do a small patch test on a little area of the inner forearm or thigh and wait 24–48 hours. Avoid putting products that contain potassium sorbate on broken, red, or irritated skin. If your baby has eczema or a history of skin sensitivity, consider choosing products labeled without this preservative. If you see persistent redness, bumps, swelling, blistering, or if your baby seems uncomfortable, stop use and contact your pediatrician.
The Cosmetic Ingredient Review (CIR) has strong evidence that potassium sorbate can cause skin allergy or irritation in some people — so watch for rashes or worsening skin. Some product-verifying programs restrict or avoid this ingredient unless manufacturers provide extra safety information. Other official reviews note low concern for cancer or developmental harm and that it does not build up in the body (Environment Canada, FDA references).
