Highlighted ingredients are regulated somewhere; red ones are restricted in at least one location we track. Dotted ones are listed below.

Fragrance allergens, essential oils and alcohol

Fragrance allergens on the EU list: Benzyl Alcohol (Benzyl Alcohol: The EU label rule applies when it is used as a fragrance. In sunscreens it is often a preservative.)

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.

Note: Brand page prints 'Helianthus Annuus (Sunflower) Seed Oil Stearic Acid' without a comma; split into two ingredients here. Travel and 32 oz refill pages carry the same list. The antioxidant blend is kept as one item as labeled. Asterisks marking organic ingredients were removed.

Common questions about Stream2Sea Water Sport Sunscreen SPF 30

Is Stream2Sea Water Sport 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 Stream2Sea Water Sport 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 Stream2Sea Water Sport Sunscreen SPF 30 contain oxybenzone?

No. It contains neither oxybenzone nor octinoxate, the two chemicals banned under Hawaii’s statewide law.

Is Stream2Sea Water Sport Sunscreen SPF 30 a mineral or chemical sunscreen?

Mineral. Its UV filter is titanium dioxide 8.8%.

Is the titanium dioxide in Stream2Sea Water Sport 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 Stream2Sea Water Sport 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.
