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. ### Does Thinksport / Think Thinkbaby 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 Thinkbaby 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 Thinkbaby Clear Zinc Sunscreen SPF 30 non-nano? The brand labels its mineral filter as non-nano. Particle size is a brand claim: US sunscreen labels aren’t required to state it, and no sunscreen law we track regulates it. ### Is Thinksport / Think Thinkbaby Clear Zinc Sunscreen SPF 30 water resistant? Yes, for up to 80 minutes of swimming or sweating, according to its label. Reapply after 80 minutes in the water, immediately after towel drying, and at least every 2 hours. ### What is the NDC and UPC for Thinksport / Think Thinkbaby Clear Zinc Sunscreen SPF 30?
