The FAQs below cover the most common questions and concerns our customers have about our products.

Yes, our products are safe to use on children older than 6 months of age. In fact zinc oxide is one of the ingredients The Skin Cancer Foundation recommends parents look for in the sunscreens they buy.

We have checked with our chemists in order to give you the most accurate information on nano-particles and all of our products are free of them. In December of 2008 Consumer Reports Health did tests on five brands of sunscreen including Zinka. We were the only company out of the five that was nano-particle free. Check out their website at to get more in depth information on the test.

Here is some more info on the concerns with nano-particles:

There has been speculation that physical sunscreen ingredients, like zinc oxide and titanium dioxide release nano-particles into the water. When these particles settle, they can clog the pores of marine life like coral. There is no conclusive data on this that I am aware of.

The self proclaimed “Environmental Working Group” publishes reports that basically associate something bad with every ingredient used for sunscreen. If they don’t someone else will. There are no confirmed results of their findings. Some believe the FDA doesn’t regulate sunscreen, however that is completely false. They pre-approve and publish a list of ingredients that can and can’t be used in sunscreens. If they deem an ingredient to be harmful then it will be removed. These studies are inconclusive and don’t take levels of percentages into play. It is common knowledge to most that there have always been things that are healthy in certain doses and potentially not in large amount.

There will always be someone who says something is wrong with everything… 6 months later, they will change their mind to focus their attention on something else. There is a lot of money spent behind the scenes by influential companies to try and swing customer perception towards their products and their respective ingredients. This is very apparent when everyone was convinced that Mexoryl was the greatest thing to ever hit the US. What they didn’t advertise is the fact that it is impossible to stabilize it in a waterproof solution, so it’s basically useless. The latest buzz word that they are pounding is Helioplex. This is just a combination of two active ingredients that are commonly found in a number of existing formulas… They basically just made up a new fancy word for something that has been used for a long time.

In conclusion, you will never satisfy 100% of the market and it is very expensive to try. You need to be confident with your formula, the way it wears and its overall performance. We have always operated under the notion that the most effective sunscreen is one that someone will actually wear. It doesn’t matter what a sunscreen contains or does if nobody will apply it because it feels like mud. The notion that wearing no sunscreen at all is better than wearing certain sunscreens is absolutely ridiculous. The market changes and so do the buzz words.

For what it’s worth.. if you bottle a formula without nano-particles, then another contingent of people will complain that it doesn’t have a physical block. So far, it has proven impossible to please everyone with a single formula because someone is always coming out with a new test that says you should or shouldn’t be doing one thing or another.

Since it is water-resistant Zinka Nosecoat won’t just wash off with water. The best thing to use is baby wipes. If you don’t have any wipes then a paper towel or cloth towel will work well too.

Soak the garment in OxiClean and then run it through the wash.

Yes, the color of the Nosecoat tube is the color of the sunscreen.

UVA rays penetrate deeper layers of the skin, damage collagen and cause wrinkling and leathering of the skin.
UVA rays also penetrate glass, even car windows.

UVB rays are the principal cause of reddening of the skin and sunburn, which can lead to melanoma (the most advanced case of skin cancer) and direct DNA damage. UVB rays are the strongest from 10:00 a.m. to 4:00 p.m., but they can burn and damage the skin year round especially in higher altitudes.
