Is Ensulizole safe during pregnancy?
Chemical sunscreen filter FDA wants more safety data on. Mineral sunscreen is the dermatologist pick in pregnancy; sun protection still matters.
What the sources say
FDA has asked for more safety data on ensulizole before calling it generally recognized as safe, while stressing this is not a finding that it is unsafe. A 2025 pregnancy photoprotection review lists phenylbenzimidazole sulfonic acid among organic filters with low systemic absorption. AAD recommends a zinc oxide and/or titanium dioxide sunscreen during pregnancy. Limit: when possible choose mineral sunscreen; if a chemical sunscreen is what you have, using it is better than burning. No breastfeeding-specific guidance beyond keeping products off the nipple.
Common alternatives
Also listed as
2-phenylbenzimidazole-5-sulfonic acid, eusolex 232, pbsa, phenylbenzimidazole sulfonic acid
