Regulators / frameworks: EU Cosmetic Regulation, Denmark (national ban for under-3s)
Parabens are esters of para-hydroxybenzoic acid used as preservatives in cosmetics, pharmaceuticals and food. Five parabens are banned in EU cosmetics under Annex II of Regulation (EC) 1223/2009 (isopropyl-, isobutyl-, phenyl-, benzyl-, pentyl-paraben). Propyl- and butyl-parabens are restricted to lower concentrations under Annex V. Some parabens have shown weak estrogenic activity in laboratory studies.
Always verify each substance's current regulatory status at the primary register before relying on it.
