For newborns and young babies (0–6 months) sodium lactate can be used safely in small amounts when products are made for babies. Because baby skin is thinner and more easily absorbs ingredients, there is a slightly higher chance of irritation or increased absorption if the ingredient is used in strong concentrations or the wrong pH.
Choose products made for infants that list sodium lactate at low concentrations or that are marked safe for babies. Prefer rinse-off products (like gentle cleansers) over leave-on lotions that list sodium lactate unless the product specifically says it’s safe for newborn skin. Use a very small amount the first time on a small patch of baby’s forearm or behind the knee and wait 24 hours. If you see any redness, swelling, rash or blisters, stop use and call your pediatrician.
Industry safety reviews and national cosmetic guidance note limits on how sodium lactate can be used (concentration and pH limits) and advise caution; a position paper also lists it as able to increase skin penetration. Do not use products with sodium lactate on broken, red, or inflamed skin. Avoid repeated use of adult, high-strength, or professionally applied products that contain sodium lactate on infants. If product labeling is unclear, check with the maker or your child’s doctor.
