For infants (0-6 months): Alginic acid is a thickener made from seaweed and is generally low risk for babies when used on normal, unbroken skin. It is often used to give creams and gels a smooth feel.
Use products that are made for babies and keep usage simple. Apply a small amount to a tiny area first (a patch test on the forearm or inner thigh) and watch the area for 24–48 hours. Do not use on red, raw, or broken skin. If your baby has eczema or very sensitive skin, check with your pediatrician before using new products.
Stop use and contact your pediatrician if you see redness, swelling, a rash, blisters, or any breathing trouble after application. Some product standards ask manufacturers to show extra safety information before using this ingredient in finished products—this is a product-level restriction from regulatory or industry reviewers (for example, the U.S. food safety authority, Environment Canada assessments, and cosmetic safety reviewers). Those reviews say the ingredient itself is low concern, but parents should still avoid products with lots of other unfamiliar or strong ingredients and watch for reactions.
