Common questions about Thinksport / Think Thinkkids Brush-On Sun Shield SPF 30
Is Thinksport / Think Thinkkids Brush-On Sun Shield 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 Thinkkids Brush-On Sun Shield 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.
