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

None of the 80 fragrance allergens on the EU list appear on this label, and it lists no fragrance, essential oil or drying alcohol.

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: Discontinued: saltandstone.com lists no SPF products as of 2026-09-23 (full Shopify catalog checked). Ingredients from the FDA DailyMed label (Salt & Stone, Inc., SPL effective 2023-10-28); label lists inactives alphabetically. Directions say to use a water-resistant sunscreen if swimming or sweating, so recorded as not water resistant. 'Keip' kept as printed (likely 'Kelp'). No brand product page or image found; size not stated on the label text. Appears to be a different formula from the Lightweight Sheer Daily Sunscreen SPF 40.

Common questions about Salt & Stone Lightweight Sheer Mineral Sunscreen SPF 30

Is Salt & Stone Lightweight Sheer Mineral 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 Salt & Stone Lightweight Sheer Mineral 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 Salt & Stone Lightweight Sheer Mineral Sunscreen SPF 30 contain oxybenzone?

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

Is Salt & Stone Lightweight Sheer Mineral Sunscreen SPF 30 a mineral or chemical sunscreen?

Mineral. Its UV filter is zinc oxide 15.7%.

Is the zinc oxide in Salt & Stone Lightweight Sheer Mineral 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 Salt & Stone Lightweight Sheer Mineral Sunscreen SPF 30 water resistant?

No. It makes no water-resistance claim, so it isn’t meant for swimming or heavy sweating. Use a water-resistant sunscreen for time in the water.

What is the NDC for Salt & Stone Lightweight Sheer Mineral Sunscreen SPF 30?

Salt & Stone Lightweight Sheer Mineral Sunscreen SPF 30 is listed with the FDA under National Drug Code 71585-144. The NDC identifies this sunscreen on its FDA drug label (DailyMed); package sizes carry longer package NDCs.
