US labels don’t have to name the allergens inside a fragrance, so there may be more than this list shows. The EU requires these allergens to be named on cosmetic labels above 0.001% in leave-on products ([Regulation 1223/2009, Annex III](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:02009R1223-20250501)).

Common questions about Thinksport / Think Thinkbaby Safe Sunscreen SPF 50+ Is Thinksport / Think Thinkbaby Safe Sunscreen SPF 50+ reef safe? “Reef safe” isn’t a regulated label claim, so we answer by law instead.

In Maui County (Maui, Molokaʻi, Lānaʻi), which allows only mineral sunscreens, it is allowed. In Hawaiʻi County (the Big Island), which has a mineral-only rule for sales, it is allowed. Oʻahu and Kauaʻi have no county rule, so only the statewide law applies there. Does Thinksport / Think Thinkbaby Safe Sunscreen SPF 50+ contain oxybenzone? No. It contains neither oxybenzone nor octinoxate, the two chemicals banned under Hawaii’s statewide law. Is Thinksport / Think Thinkbaby Safe Sunscreen SPF 50+ a mineral or chemical sunscreen?
