For toddlers (1–2 years) propylene glycol is usually low risk at small amounts. It can cause skin or eye irritation in some children and may help other chemicals soak into the skin more easily.
Use products that list it at low concentrations, avoid putting it on broken, red or sore skin (including the diaper area), do a small patch test first, and stop use if you see redness, swelling, or a rash. Keep products away from your child’s mouth and eyes.
Watch for skin irritation or rash — this is the main concern (based on safety reviews and toxicity listings). Also note that some safety reviews say it can increase skin absorption of other ingredients (Cosmetic Ingredient Review), and government assessments have flagged possible effects at high exposures (Environment Canada). The U.S. National Library of Medicine lists it as a possible skin irritant. If you notice any reaction, stop use and talk to your pediatrician.
