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 SPF 50+ Baby Clear Zinc Sunscreen for Sensitive Skin 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 SPF 50+ Baby Clear Zinc Sunscreen for Sensitive Skin contain oxybenzone? No. It contains neither oxybenzone nor octinoxate, the two chemicals banned under Hawaii’s statewide law. ### Is Thinksport / Think Thinkbaby SPF 50+ Baby Clear Zinc Sunscreen for Sensitive Skin a mineral or chemical sunscreen? Mineral. Its UV filter is zinc oxide 23.4%. ### Is the zinc oxide in Thinksport / Think Thinkbaby SPF 50+ Baby Clear Zinc Sunscreen for Sensitive Skin non-nano? Its Drug Facts ingredient list doesn’t state particle size, and US labels aren’t required to. Many brands make non-nano claims elsewhere on the pack or website. No sunscreen law we track regulates nano particles. ### Is Thinksport / Think Thinkbaby SPF 50+ Baby Clear Zinc Sunscreen for Sensitive Skin water resistant?
