How do you avoid sunscreen stains on white clothes?
I have read (in a blog, referencing a call to Coppertone customer service) that avobenzone is the ingredient responsible for those stains. The reason it doesn't show up until after you wash your clothes is that it reacts with the iron in your water. I would assume that people with treated water ("city water", we call it) would not have these stains, while those of us with well water do.I went to the drug store and bought some sunblock WITHOUT avobenzone. I took some of several sprays and one lotion and applied directly to an old white t shirt, then washed the t- shirt. Guess what? Some of the sunscreens WITHOUT avobenzone still stained! Here are the results, summarized.*PLEASE DO NOT TAKE THIS AS A GUARANTEE! These are my results, with my water and detergent, etc.BEST:Coppertone Oil Free lotion SPF 15, (white bottle) NO AVOBENZONE left no stain.NO-AD lotion SPF 15 (pink bottle) NO AVOBENZONE left a very faint "off white" stain that would not be noticed on anything except white - I suspect it's more the oil in the lotion that the sunblock.OK: I would use these when I had on colored fabrics, NOT WITH WHITE!!!!!Coppertone Dry Spray SPF 10 (brown can) NO AVOBENZONE left a faint stain that came out with bleach.Neutrogena Spray SPF 45 WITH Avobenzone left a faint stain. NO-AD Spray Lotion 30 (kids, Tinkerbell can) NO AVOBENZONE left a faint stain.Rite-Aid (white can with purple letters) NO AVOBENZONE left a faint stain.WORST:NO AD lotion SPF 50 (orange bottle) NO AVOBENZONE!?! left an orange stain. Light, but wanted to list it here because it did NOT have Avobenzone.Coppertone Ultraguard Spray SPF 15 (white can with blue top) WITH AVOBENZONE left horrible dark orange stains that would not come out with bleach.Walmart store brands of SPF 30 spray (white and purple can) WITH avobenzone.Coppertone Sport Lotion SPF 30 (Blue bottle) WITH Avobenzone .SO - No avobenzone does not equal no stains, but it seems to mean the stains will be lighter. Lotions also seem to be better than sprays. Bummer. I am trying to apply and let it sink in before dressing, and when we go to the beach when we HAVE to use sprays to chase down a kid and a husband who hate sunscreen application, I guess we will wear old/colored clothes. I am going to call my local Avon rep and see what she's got for me - I'm willing to pay for something that won't stain!That said, for stains you already have, I have used "The Works" bathroom cleaner, spraying onto wet clothes (usually right after I take them out of the washer and find new stains) and letting them sit for 15-30 minutes. I have not had any clothes damage - clored and white cotton t-shirts, bathing suits, everything seems fine. I think any cleaner that is made to remove rust stains would work, so try what you have before running out and buying "the Works".
What specialist material is used in sunscreen?
cream
What does sunscreen contain?
Titanium dioxide, zinc oxide and avobenzone all protect across the entire UVA spectrum. Many also include UVB-absorbing ingredients, and the rest of the product is the same as any moisturizer or lotion (water, emollients, water-binding agents, preservatives, etc.)
What chemical formula is sunscreen?
hi, there are sunscreens that are Chemical, and sunscreens that are Physical: Chemical sunscreens absorb UV rays: Octylmethylcinnamate, avobenzone, PARSOL1789, PABA, Mexoryl, Benzophone, oxybenzone, octocrylene, homosalte Physical Sunscreens reflect UV rays: zinc oxide, titanium dioxide
What are the ingredients for sun screen?
Some of the ingredients contained in chemical sunblock designed to prevent UVB radiation include: · Cinnamates · OMC (Octyl Methoxycinnamate) · Ethylhexyl p-Methoxycinnamate · Salicylates · OCS (Octyl Salicytate) · Homomenthyl Salicylate · Triethanolamine · PABA (Para Aminobenzoic Acid)· Padimate O · Padimate A · Glyceryl Aminobenzoate · Octyl Dimethyl Paba · Octocrylene · Zinc Oxide · Titanium Oxide The sunscreen ingredients that are used to absorb UVA radiation include: · Benzoophenones · Oxybenzone · Dioxybenzone · Avobenzone
What part of DNA absorbs uv light?
In suntan lotion it is avobenzone and/or octyl methoxycinnamate. Many organic molecules (natural and man-made polymers) absorb UV. DNA absorbs UV-B (which can cause damage) - as can the cornea of the eye! The cornea also absorbs UV-A but seems to not suffer much with it. Much of the sun's UV-A, UV_B and UV_C radiation is absorbed by the Ozone Layer when it enters the atmosphere.
What is the highest spf number for children under 2 years?
Many sunscreens are advertised for kids, but reviews say the only differences between these and adult sunscreens are irritating fragrances, and sometimes, the form of UVA protection. Titanium dioxide and zinc oxide are less irritating to sensitive skin than avobenzone. Blue Lizard Baby sunscreen SPF 30 (*est. $13/9 ounces) contains a combination of titanium dioxide (10%) and zinc oxide (5%), and it's both fragrance and chemical free. Keep in mind that Blue Lizard Baby is identical to their Sensitive formula. Banana Boat Sport (*est. $13/8 ounces) is recommended in two sunscreen reviews, but again, you'll need to read the label to be sure you're getting UVA protection. The Banana Boat Sport spray sunscreen formula contains avobenzone, while the Sport lotion sunscreen formula does not have any of the recommended UVA-protecting ingredients. Banana Boat Kids Quik Blok Sunblock Spray Lotion (*est. $7/8 ounces) contains avobenzone, which can be more irritating to kids' skin than the titanium dioxide or zinc oxide used in Blue Lizard Baby sunscreen. Spwipes (*est. $9/10-pack) is sunscreen packaged in the form of disposable towelettes. While this sounds like a convenient option for kids who might not sit still for a lotion application, Spwipes don't contain any UVA-protecting ingredients. They come in SPF 30 and are water and sweat resistant. One 10-pack provides about four adult applications. While throwaway towelettes might be ideal for a hike in the woods when you don't want to lug a big bottle along, it's more cost effective and safer to choose one of the sunscreens in ConsumerSearch Fast Answers, which offer UVA protection and more applications for the price.
Which rays emitted by the sun can be detrimental for your health?
Your typical sunburn is caused by UVB radiation from the sun and is what most sunscreens are made to protect against. The radiation that really causes the detrimental health problems is UVA however much less potent then UVB UVA is the culprit that causes wrinkling, skin cancer, and other health problems associated with the sun. Unlike UVB UVA penetrates deep into the tissue causing damage that is much more detrimental. Unfortunately studies have shown that although many sunscreens say they protect against UVA there is a huge discrepancy when looking at the amount of protection given to UVB compared to UVA. If there has been a problem in the past with health problems caused by sun radiation my suggestion would be to find a sunscreen containing the ingredient Avobenzone the only drug shown to protect against long wavelength UVA.
How do you avoid sunscreen stains on clothing?
I have very few tips on how to avoid it, but if you do get the stains, I do have a remedy that works to get them out. Before I note that remedy, if you are experiencing orange or brown stains as a result of sunscreen, it MAY be due to a reaction between an ingredient avobenzone in the sunscreen product and the iron in the water (hard water, usually). If the above interaction seems to be what's causing it, then you can try to avoid the stains by not using sunscreen products that have avobensone. There are some very common brands of sunscreen that don't have that ingredient. You just need to read the label. You also need to try to avoid hard water. Get a water softener, etc. If you do get the stains, here's what's worked for me on some really, really bad sunscreen stains: 1) Buy a bottle of BIZ stain remover (in you local grocery store's detergent aisle). BIZ has enzymes that help remove these "reaction" stains. 2) directly apply a bit of BIZ to the stain and work it into the clothing. 3) Mix 1/4 cup white vinegar and 1/4 cup of biz with hot or very warm water. The vinegar will help neutralize the iron if you have hard water. 4) Let clothing soak in this mixture for a few hours. Periodically check the clothing and if you still see affected areas, gently scrub that area and then let soak longer. 5) Dump soaking clothing in washer and use BIZ in place of your regular detergent and wash with HOT water. 6) At end of wash cycle, check clothing. If stains still exist, do not dry them. Repeat above until they are out.
Is sunscreen bad for you?
Some sunscreens can pose risks. The sunscreens under question are chemical sunscreens (ingredients like: octylmethylcinnamate, oxybenzone, avobenzone, benzophone, mexoryl, PABA and PARSOL 1789.) These ingredients are in question because they have the ability to enter the blood stream and disrupt the endocrine system. Hormones are released by your endocrine glands, and hormones are lipid (fat) based molecules. Many of these sunscreen ingredients are also fat based, and have the ability to "confuse" your body's reception to it's own hormones. Sunscreen chemicals that mimic hormones often mimic estrogen, and are called xenoestrogen. There are several more reasons why chemical sunscreens are in questions: 1) because they generate a great amount of free radical activity. (free radicals are those things we're always trying to fight with anti-oxidants, free radicals can damage the cell wall) 2) chemicals sunscreen cause allergic reactions to many sensitive folks 3) finally, these chemicals are linked to damaging the coral reef! look up sunscreen and the reef and you will see photos of diseased and dying reefs. (and to think, it was only the effect of a minute amount of sunscreen washing off in the water daily, it had a big effect!) I hope you'll stay safe in the sun and make smart decisions when buying sunscreen.I use the EWG to help me with my product choices: http://www.cosmeticsdatabase.com/special/sunscreens2008/index.php I just bought #2 TruKid. It's awesome, good on sensitive skin, mildly scented, and broad spectrum physical block, which makes me happy I'm not harming the environment or myself. == == == == Kevin Trudeau thinks it causes cancer, but then he spent time in prison.
How do you avoid facial wrinkles?
To help avoid facial wrinkles, it's important to protect your skin from the sun by using sunscreen daily, staying hydrated, eating a healthy diet rich in antioxidants, not smoking, and following a consistent skincare routine that includes moisturizing and using products with retinoids or peptides. Additionally, avoiding repetitive facial expressions that can lead to the formation of wrinkles, such as squinting or frowning, can also help prevent them.
What does the SPF number on sunscreen lotions mean?
The SPF of a sunscreen is a laboratory measure of the effectiveness of sunscreen - the higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn). The SPF is the amount of UV radiation required to cause sunburn on skin with the sunscreen on, relative to the amount required without the sunscreen.[10] So, wearing a sunscreen with SPF 50, your skin will not burn until it has been exposed to 50 times the amount of solar energy that would normally cause it to burn. The amount of solar energy you are exposed to depends not only on the amount of time you spend in the sun, but also the time of day. This is because, during early morning and late afternoon, the sun's radiation must pass through more of the Earth's atmosphere before it gets to you. In practice, the protection from a particular sunscreen depends on factors such as: * The skin type of the user. * The amount applied and frequency of re-application. * Activities in which one engages (for example, swimming leads to a loss of sunscreen from the skin). * Amount of sunscreen the skin has absorbed. The SPF is an imperfect measure of skin damage because invisible damage and skin aging are also caused by ultraviolet type A (UVA, wavelength 320 to 400 nm), which does not cause reddening or pain. Conventional sunscreen blocks very little UVA radiation relative to the nominal SPF; broad spectrum sunscreens are designed to protect against both UVB and UVA.[11][12][13] According to a 2004 study, UVA also causes DNA damage to cells deep within the skin, increasing the risk of malignant melanomas.[14] Even some products labeled "broad-spectrum UVA/UVB protection" do not provide good protection against UVA rays.[15] The best UVA protection is provided by products that contain zinc oxide, avobenzone, and ecamsule. Titanium dioxide probably gives good protection, but does not completely cover the entire UV-A spectrum, as recent research suggests that zinc oxide is superior to titanium dioxide at wavelengths between 340 and 380 nm.[16] Owing to consumer confusion over the real degree and duration of protection offered, labeling restrictions are in force in several countries. In the EU sunscreen labels can only go up to SPF 50+ (actually indicating a SPF of 60 or higher)[17] while Australia's upper limit is 30+ [18]. The United States does not have mandatory, comprehensive sunscreen standards, although a draft rule has been under development since 1978. In the 2007 draft rule, Food and Drug Administration (FDA) proposed to institute the labelling of SPF 50+ for sunscreens offering more protection. This and other measures were proposed to limit unrealistic claims about the level of protection offered (such as "all day protection").[19] UV-B sunlight spectrum (on a summer day in the Netherlands), along with the CIE Erythemal action spectrum. The effective spectrum is the product of the former two. The SPF can be measured by applying sunscreen to the skin of a volunteer and measuring how long it takes before sunburn occurs when exposed to an artificial sunlight source. In the US, such an in vivo test is required by the FDA. It can also be measured in vitro with the help of a specially designed spectrometer. In this case, the actual transmittance of the sunscreen is measured, along with the degradation of the product due to being exposed to sunlight. In this case, the transmittance of the sunscreen must be measured over all wavelengths in the UV-B range (290-320 nm), along with a table of how effective various wavelengths are in causing sunburn (the erythemal action spectrum) and the actual intensity spectrum of sunlight (see the figure). Such in vitro measurements agree very well with in vivo measurements.[20] Numerous methods have been devised for evaluation of UVA and UVB protection The most reliable spectrophotochemical methods eliminate the subjective nature of grading erythema.[21] The above means that the SPF is not simply the inverse of the transmittance in the UV-B region. If that were true, then applying two layers of SPF 5 sunscreen would be equivalent to SPF 25 (5 times 5). The actual combined SPF is always lower than the square of the single-layer SPF.
