Common questions about Thinksport / Think Thinksport Kids Clear Zinc Sunscreen SPF 30 Is Thinksport / Think Thinksport Kids 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 Thinksport Kids 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. Does Thinksport / Think Thinksport Kids Clear Zinc Sunscreen SPF 30 contain oxybenzone? No. It contains neither oxybenzone nor octinoxate, the two chemicals banned under Hawaii’s statewide law. Is Thinksport / Think Thinksport Kids Clear Zinc Sunscreen SPF 30 a mineral or chemical sunscreen? Mineral. Its UV filter is zinc oxide 20%. Is the zinc oxide in Thinksport / Think Thinksport Kids Clear Zinc Sunscreen SPF 30 non-nano? The brand labels its mineral filter as non-nano.
