Want to buy something locally. What works for you may not work for anyone else and to protect yourself (and them) the best bet is to run your product through the official testing channels. So you have seen it suggested that layering sunscreens with different actives can help. I have always been involved in the sunscreen market and have worked with all of the chemical filters including the Tinosorbs (Ciba) and Univul Grades (BASF) plus the original Parsol MCX and 1789 from Roche, now DSM. If one is very sensitive then I guess 93% UV is filtered with SPF 15, vs getting 97% UV filtering with SPF 30, is the benefit. Ive produced some really nice high SPF products with these chemical filters and it is much easier to get a light feeling product that people want to wear but these days as pretty much all of my clients want natural I work with Titanium Dioxide and Zinc Oxide. Those pre-dispersed UV filters are just as hard to use as the powders as it is not just the form of the zinc that makes it tricky, it is preventing it from agglomerating in a formula and making sure it is evenly distributed. I spent around $5000 of my own money testing sunscreens to get the data about how important testing is. Zinc is by far the hardest ingredient to work with in any situation because of its charge density, Titanium Dioxide doesnt have this problem. After some more research, it was your blog that stopped me at my tracks! Ive read that zinc oxide and titanium dioxide if inhaled can be dangerous. I do wish, generally, that there was more expert guidance on the internet for hobbyists interested in home experimentation, who have no intention of using any cosmetic product long-term without testing, but still enjoy the challenge. Now I am afraid that I am magnifying the sun ray on my skin and age me faster by exposing myself to intense uv rays.. I was also reading a post you wrote on emulsifiers, again, all so new to me!

In creating this recipe, we took inspiration from sun protection products to create a DIY loose powder for summer. Also, are you a chemist? And do you know if Zinc ox.

However, theres times when I just cant do without it, mainly being water sports such as wake-boarding or surfing. Thanks so much , Dear RealizeBeautyEd, There goes another $3000 Come up with a wonderful formula. Melt beeswax, [], DIY Sunscreen Making your own sunscreen doesnt have to be hard! Thank you in advance~. Oils have no pH so you dont need to consider that in an oil-only formula. . Great post! This inevitably results in a very thick application that is nothing like what the average person would use and is why some brands achieved SPF for their product. Its also unfortunate that the home chemists who do go commercial successfully dont clarify that at that point they are often working with copackers/white label facilities who have appropriate industrial equipment and testing protocols. I own a small skincare company, and have been formulating a zinc oxide sunscreen for several years. Ive been doing a lot of research and found the pros and the cons. I dont own a brand. Thanks again! The lips are the start of the digestive system so it might be coming from food exposure and avoiding something you are eating might just relax the lips enough to cope with a lip balm but then again it might not. 1 set of mini measuring spoons (TAD, SMIDGEN, DROP). And something cosmetically elegant. check out the website Special Chemicals here for a list of options. Cover the jar and shake it for an additional 30 seconds to further blend the powders together. I have a feeling this is just mindless spam as it isnt even relevant to the article but it is somewhat typical of the shadow boxing arguments that go on online. Zinc Oxide powder is either going to leave you very white (large particles) or exposed to nanoparticles (if the zinc goes on clear). i stumbled on your blog, its great! Pharmaceutical grade pigments are not necessarily good enough to give a solid SPF so its possible to have a zinc product that goes on white and looks like its covering when in reality the coverage is full of minute holes. Hi Whitney, I cant talk for a specific sunscreen but zinc alone is able to provide good coverage and it should be enough for egret day use. Then theres the mixing and general manufacturing method. Are the official testing channels the greatest thing since sliced bread? However, after reading your article I am now not sure what to do. So the zinc oxide could help with skin problems, but leave a greasy feel? There is nothing wrong with the ingredients that Ive highlighted and looking at reviews for this product people seem to like it. UV naturals is another that I know does everything properly and invests in full and regular testing. I appreciate that this is not a good life plan and accept that I might well suffer for it but I am yet to find a daily use product that I feel happy in wearing. Ill check out Nivea/Hamiltons, thanks for the recommendations. If all commercially produced sunscreens state reapplication is needed after 80 minutes, then, theoretically wouldnt a stated SPF of 15 (with a poorly applied functional real life SPF of 9) be adequate for someone who takes >10 minutes to burn? Also without proper testing you can never be sure if your creation is giving you the protection you think it is. Heat will help to disperse zinc oxide but it isnt essential though. I can understand why people might feel uncomfortable with formulations they havent made or ingredients they have no relationship with but I can honestly say that making your own Sunscreen is far more risky. Am i correct to assume that mineral sunscreen manufacturers are aware of this issue, and formulate their product accordingly so that it provides effective and uniform coverage? Layering a bad product might help a bit but it wont be pleasant to use and may still not give you enough of an SPF. Here is a link relating to your original question:http://www.cosmeticsdesign.com/Formulation-Science/Encapsulation-technology-can-increase-SPF-of-organic-sunscreens.

I cant make personal recommendations for anyone else as this is a science blog and not a beauty/ product review blog. This quick and easy recipe will keep you safe in the sun without absorbing the toxic chemicals from regular sunscreen. I have one tinted moisturiser which recorded an SPF of 12.8 on the market (a secondary sunscreen) and two zinc only formulations pending marketing that meet SPF 15. I was only wistful that there arent more like it- with the understanding, as I think we agree, that experts cant be expected to give away knowledge or tutor for free, only appreciated for whatever guidance they choose to offer. There are fragrance free, cosmetic sunscreens, light weight sprays and gels plus heavier more traditional products. Just because its a creamy goo to the naked eye clearly means nothing. This year I was planning to order zinc from Amazon so I could try making a sunscreen that didnt smell like diaper ointment, but it sounds like maybe Im better off sticking with the diaper ointment since the zinc is already blended into it. Wow, the fact that someone would sell something like that with those claims worries me greatly! Rose tinted specs are well and truly binned. SPF testing of mineral cosmetics used to involve applying a thick layer of moisturiser or base product first then layering the mineral foundation at the required 2mg/cm2 rate over the top. Im just wondering how accurate that impression is- whether immediate use and frequent reapplication affect the clumping, settling, and dispersal issues discussed, particularly as it relates to what I suspect are the majority audience for this post- folks who live mostly indoors but just want to whip something up for their upcoming beach holiday and dont plan to use this as a daily application for farm work or bikini modeling. Thanks! We all wish there was a sunscreen that can address the 370-400nm wavelength of UVA1! I do seem like Dr No on this post and I get that. Ignorance can be so dangerous! Im sure these companies test their sunscreens in a lab, but if the percentage of the zinc oxide is the same and every single other ingredient is the same, how is one more effective than the other? Hi there, Do you know if this still occurs with zinc particles 100-200nm in size? I hope that helps, keep asking the questions as Ill answer what I can but with sunscreen Im sticking by my advice not to make your own unless youve invested in testing to confirm you are on the right track. Point of Interest. i have some qns, wonder if you can help? Im disappointed that it cant safely be done at home, but grateful now that I know better than to put my family at risk. I was wondering if since store-bought oxide ointment could be used solely as sunscreen. My homemade experiment was spot on and passed all tests . You will need either an emulsifier or suspending agent or both for your sun protection product. Even a change in fragrance can affect SPF. The reason I am so against people making their own sunscreen is because while the risks to the individual of getting cancer from using either a nano particulate sunscreen or one made with chemicals are nothing compared to the risk of developing skin cancer from wearing an ineffective product. http://www.keeperofthehome.org/how-to-make-your-own-sunscreen-lotion. Also you dont need an SPF to utilise zinc in the formula, you could add zinc anyway as it can be helpful as an antimicrobial agent in skin care and can also help to dry the skin a little if it is too greasy (although it can also feel greasy so thats the pay-off). Help! Most decent DIY recipes indicate to use a percentage of zinc oxide mixed with butters/waxes/oils/etc. Halfway filling up Amazon with (expensive high quality) products and then came across your website! Would that work as a good sunscreen? The variability of the suns intensity is not something that can be controlled outside of a laboratory and so it is easier to fall into a trap of thinking that something is working better than it is not if a) the persons UV exposure wasnt actually as long or as extreme as they perceived or b) the person used more or less than the recommended amount of sunscreen. non-nano uncoated particle zinc oxide works great (its NOT expensive at all), no burns, great tan, no clumps. Id be fine with nano but many people looking for natural products are not). The bit that the craft market dont realise is just how much research and how many options exist with zinc. I do drive a lot so my arms gets a beating from the sun but i always make sure i reapply, yet i still have this nasty zebra tan. Zinc Oxide homogeneous dispersions do not require high shear mixers or homogenizers so not only are they easy to use, they also provide broad range UVA and UVB sun protection using non micronized zinc oxide, the same material that Badger uses in its sunscreens. I expect now that daily sunscreen use is becoming more widespread and sunscreen is added to so many lotions and cosmetics, more people will become sensitized to it like my daughter and I did. In other words, how do we know a sunscreen with zinc oxide works without the issues you discussed? Also penetration of a substance through the skin is not entirely (or even majority) about size, its quite complex. Ive seen many different sunscreen formulations get scaled up. Just make sure you read the MSDS as you would with any chemical and handle accordingly while manufacturing. Thats really my point. I realize sunscreens degrade especially Avobenzene without another to stabilize it. SPF 15 will not protect a fair skinned person here in Australia where the UV index can easily exceed 10 and with the added bonus of the hole in the ozone layer we do need as much protection as we can get. Vegetable oils such as soy, olive, hemp, avocado and others contain different benefits that condition your skin. Being aware of the testing required to ensure a functional product like a sunscreen actually does work for people other than yourself is a key responsibility of the brand owner. A thorough mix before using might be enough but not always. I wanted to ask a question about using zinc oxide powder as a sunscreen. Formulating together also means that there is no incompatibility between carriers, emulsifiers or film formers. Whats your thought? Just keep in mind that a poorly covering sunscreen is actually worse than none at all and you will understand why this is all so dangerous. Its efficacy might be enhanced by other ingredients or reduced too, depending on what the rest of the formula contains. So Ive been living by this. Ive tried some natural brands (I dont want to name and shame them) that I dont think were properly formulated to disperse the ZnO evenly, just by how badly I burned when using them. Your email address will not be published. Zinc dispersions will have a shelf life and it would not be unusual for that to be around 2-3 years. Does this claim hold water? If you are a very fair skinned surfer what Id recommend is something like a Burquini type of garment or one of the all-in-one lightweight diving suits that we have to wear on the barrier reef. I do know there are some good ones out there but Ive also seen bad. Soy does contain phyto-eostrogens which indisputably interact with mammalian androgen receptors.

Is there anything to support the idea of laying down a chemical sunscreen, then applying a layer of physical sunscreen on top? Jemma. First off, thanks so much for the vast research and work you put into this invaluable article! Im in the US and have loved some European sunscreens that combine filters that we dont have access to, like tinosorb S and M, and have read that they can provide superior broad spectrum protection (Especially on the UVA side of things) compared to a lot of the sunscreens available here. Understandable, though, given that homespun is a solid marketing angle. Do you have any recommendations for brands of sunscreen that are natural & safe to put on the skin? (LogOut/ SPF 12 would actually work for me as Im rarely out in sunworshipping but it might not work if I used it on a sunny beach holiday. I reapplied it every hour like I used to do with commercial sunscreen. It is TGA listed and is quite popular too. This lack of rigorous testing, their marketing it as safer than chemical sunscreens and the fact that they havent done any appropriate labeling in accordance with EU and FDA regulations terrifies me since I have had several family members get serious skin cancer in the past. But that was over one year and several thousands of dollars worth of investment in time, materials and testing later and that was BEFORE we started trying to change preservative systems, add different actives, change emulsifiers and add perfumes. This doesnt sound like useful advice to me. The silicone is a big no, no though and many people looking for naturals would avoid the brand because of that. I have some friends and family waiting hopefully to act as guinea pigs to help me work out if it works! Many people, like myself, and also yourself from what i have read, come across the idea of making a homemade sunscreen with zinc oxide and it seems simple enough. The face powder that I wear contains sunscreen, however, since it is pricey, I thought that dusting powder zinc oxide on my face would be an inexpensive solution. Those that I expected would give me an easy 30 came in at a dismal 12, those that were a sure 15 were only a 7 and one that looked amazing and a sure-fire 35 ish read only 8 on the SPF scale. Such is life. Does it have an expiry date? Your chemist or health food store should be able to point you in the direction of a suitable micronised sunscreen. sowhen are u gonna sell suncreen u made for us?:))). But then came the day of reckoning. If the zinc is going grainy it is clumping and therefore not available to work as a sunscreen. I also like some of the silicone coated Zinc and Titanium particles like those made by Kobo but cant use those in my natural formulating. Great post! and conventional baby sun screen gives you a chemical burn what gives? I took them to the sunscreen testing lab and they failed. Zinc is allowed for sunscreens in the USA up to 25% and in Europe you can ad as much as you like I think but you would have to get the formula safety assessed. Would mixing mineral makeup (with titanium dioxide and zinc oxide as ingredients) with lotion make it ineffective as a sunscreen? There are many ways that we (cosmetic chemists) can boost SPF but pretty much all of the things that help film formers, absorbent spheres, SPF stabilisers etc are synthetic and cant be used to make a natural product. This is an interesting article. This is really one of the biggest challenge for a fomulator. Stir in 1 tbsp. A professional sunscreen has this tested and has to pass a UV balance screening BEFORE it even goes near to the skin. Completey out of touch, just like most skin products companies. Im at a loss. I just use an empty vitamin bottle, add about one teaspoon Olive oil for two teaspoons zinc oxide and shake really sharply. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Some UV filters do degrade (Avobenzone is one) but the product formulator should be able to account for that as the solution has been available since the late 1990s and is well known. Grind the powder and test on your skin after each addition of pigment. With that in mind, Im looking to start my own small cosmetics company, and itd really be neat if I could manage to formulate a sunscreen to sell. If all sunscreen needs reapplied after 80 minutes, even a person who burns after 5 minutes at UV index 11 should-based on the info we are publicly told here-, an SPF of 16 should be adequate. But reapply at 80 minutes and Im covered right? My problem with certain sectors of the home made market is that they fail to appreciate (or at least they seem to) the value of that detail and think that they can overcome it with lots of made with love and wistful thinking. I love Tinosorb sunscreens but i find them way too oily to use on my body. or it will be just like those commercially prepared? Manufacturers do know about zinc clumping and go as far as they can to mitigate this but manufacturers do sometimes put products that fail onto the market either it was a badly made batch that got thorough the QC department or it is a formula that turns out to not be quite as good as they thought it was. Hi there, I was wondering what you think about Zinka. As for emulsifiers I possibly didnt mention that because it would have been a given. A lot of really great information to think on.. Coconut Oil Directions 1. Adorable Baby: https://www.ewg.org/sunscreen/about-the-sunscreens/827064/Adorable_Baby_Sunscreen_Lotion%2C_SPF_30%2B/ Zinc is very tricky and while I have been making zinc based formulations for five years I can assure you that getting a good SPF is far from easy. Why had no one thought of this yet?!? I did not grow up with sunscreens either. Today we are going to be demonstrating how to create a Easy Zinc Oxide Sunscreen Recipe at home using La Lune Naturals Zinc Oxide Powder. Not to mention price goes up significantly and I just dont see the needthen again I dont see the sun as evil. I intend to use it on my neck and body. It was written more to highlight that.
