For infants and newborns (0-6 months) this ingredient should be treated with caution. It is a mild cleanser but can make the skin absorb more of what's applied and has a contamination concern for nitrosamines. This makes it less ideal for very young babies.
If you need to use a product with this ingredient on a baby: choose a product made for newborns, use it only as a rinse-off (bath or shampoo) rather than a leave-on lotion, avoid products that are sprays or could be inhaled, use sparingly and rinse thoroughly, and stop use if you see redness, rash, or eye irritation. Prefer products that list manufacturing safety or safety testing, and when in doubt pick a product formulated without this ingredient for 0-6 month infants.
Watch for skin or eye redness, irritation, or new rashes — irritation has been reported in animal and some human studies (source: European Chemicals Agency and peer-reviewed literature). Be aware of contamination concerns for nitrosamines in this ingredient (listed as a contamination concern). Also note that industry safety reviews indicate it can act as a penetration enhancer, increasing skin absorption of other substances (source: Cosmetic Ingredient Review). Some countries restrict its use or set concentration limits in certain products (source: Japan Ministry of Health). There are also data gaps for safety when inhaled (source: Cosmetic Ingredient Review), so avoid aerosolized or spray products containing it for infants.
