Fragrance allergens, essential oils and alcohol
None of the 80 fragrance allergens on the EU list appear on this label, and it lists no fragrance, essential oil or drying alcohol.
The EU requires these allergens to be named on cosmetic labels above 0.001% in leave-on products (Regulation 1223/2009, Annex III). They can cause skin reactions in people who are sensitized; they don’t affect whether a sunscreen is legal anywhere we track.

Common questions about Thinksport / Think Thinkbaby Clear Zinc Sunscreen SPF 30
Is Thinksport / Think Thinkbaby Clear Zinc Sunscreen SPF 30 reef safe?
“Reef safe” isn’t a regulated label claim, so we answer by law instead. It meets every sunscreen law we track, including the mineral-only rules in Maui County, Hawaiʻi County (Big Island) and Palau. Its only UV filters are minerals, which every law we track permits.
Is Thinksport / Think Thinkbaby Clear Zinc Sunscreen SPF 30 legal in Hawaii?
Under Hawaii’s statewide law (Act 104, which bans oxybenzone and octinoxate) it is allowed. 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.

Mineral. Its UV filter is zinc oxide 20%.
Is the zinc oxide in Thinksport / Think Thinkbaby Clear Zinc Sunscreen SPF 30 non-nano?
