Using a double boiler or a glass bowl on top of a pot with a few inches of water in it, heat the coconut oil, shea butter, beeswax and vitamin E (if using) over medium low heat until there are no solid bits left. Remove the oil mixture from the stovetop. Add zinc oxide, arrowroot powder and essential oils (if using). The FDA recommends that zinc oxide in sunscreen should not make up more than 25% of the total ingredients. Nano vs. non-nano zinc oxide. So, the one ingredient I want to touch on is zinc oxide. Zinc oxide is a mineral powder and is hands down one of the safest forms of sun protectant available. A 2010 study in the Journal of Photochemical and Photobiological Sciences stated that “based on data from internationally-recognized guideline studies and current 20+ year history of human use is that nano-structured titanium dioxide and zinc oxide are safe,” and that the “risk for humans…is considered negligible.” Generally speaking, though, eco-sunscreens are natural alternatives to traditional sunscreens: they are biodegradable and made of non-toxic ingredients, such as zinc oxide and titanium dioxide Containing 22.4% of Non-Nano Zinc Oxide, this mineral sunscreen fared very well when put under intense testing in our Manhattan-based Lab. Not only does it have a high zinc oxide percentage that provides powerful SPF32 UVA and UVB protection, but it’s also reef safe and cruelty-free. 2. Methodology. To identify the most relevant articles (available in the most well-known medical/biology/chemical databases, such as Scopus, PubMed, and Web of Science) for this review as precisely as possible, “zinc oxide nanoparticles,” “traditional techniques,” and “biomedical applications” were used as primary keywords, and “plant extracts” and “green synthesis” were 4cMCaPS. 2 Only one active ingredient: Non-nano zinc oxide. So in our reef-safe rules, we looked for only two active ingredients: non-nano zinc oxide, and titanium dioxide (but only in conjunction with zinc). For kids and babies, we’re being a little stricter and recommend that sunscreens only contain non-nano zinc oxide. SPF 30+ BROAD-SPECTRUM PROTECTION – With a sole active ingredient of 23% Non-Nano Zinc Oxide, our Tinted Face Lotion 30+ provides UVA-UVB true broad-spectrum coverage ; SAFE FOR OUR PLANET – Reef-safe, Leaping Bunny certified cruelty-free, non-GMO and biodegradable in a reusable plastic-free tin. Protect yourself and the environment! Part of the clear zinc oxide is enriched with larger particles which makes it as efficacious as regular non-nano zinc oxide making it safe to use on the skin and non-harmful to the ecosystem. Why Avoid Chemical-Based Sunscreen Chemical sunscreens are made up of ingredients like oxybenzone, octinoxate, octocrylene, and avobenzone. EWG's Sunscreen Guide. Our 2023 Guide to Sunscreens profiles more than 1,700 products, and only about one in four products meets our standards for adequate sun protection and avoids ingredients linked to known health harms. Products marketed for babies and kids do slightly better, on average, with one in three meeting our standards. Type: Mineral | Active ingredients: Titanium dioxide 2%, zinc oxide 17% | Price per The formula is hypoallergenic and non-nano (more on that later), and it leaves skin feeling soft and
