The high reflection above the uv spectrum (above 400 nm) into the visible light region of the electromagnetic spectrum is what causes the whitening effect and flashback when using inorganic sunscreens. You can use less of an inorganic sunscreen compared to an organic sunscreen Myth! All sunscreens are tested at the same density, which is 2 milligrams of sunscreen per square centimetre. That applies to inorganic, organic, spray, stick, lotion, wipes, etc. If you want to get as close as possible to the protection on the label of the sunscreen product, you need to apply it at the same density it was tested. Inorganic sunscreens sit on the skin. Organic sunscreens absorb into the skin Myth! Think of it this way, if we want to protect ourselves from the rain we need to hold the umbrella above our heads.

Only about 5 of uvb light is reflected by inorganic sunscreens and the remainder gets absorbed and converted just like organic sunscreens. The results of a measurement show how much energy is reflected by different types and sizes of titanium dioxide. The horizontal scale represents the electromagnetic spectrum with my yellow highlight marking the uv spectrum. The vertical scale represents how much of the energy is being reflected, the higher up on the chart the greater the amount of reflection. Between 250 nm and 350 nm titanium dioxide reflects less than 10 of the energy. Between 350 nm and 400 nm there is more reflection depending on the form of titanium dioxide and the particle size. The anatase form of titanium dioxide exhibits more reflection than the rutile form of titanium dioxide. These forms have to do with the way the titanium and oxygen atoms are arranged in the titanium dioxide. Sunscreens often use rutile titanium dioxide because experiential they are safer and less reactive. The same is seen with zinc oxide, with most of the reflection being above 350. The rest of the uv spectrum is absorbed.

Metal oxides, like titanium dioxide and zinc oxide, have solid structures made of alternating sheets of metal and oxygen atoms. The principle behind the uv protection is exactly the same as organic sunscreens. Instead of the arrangement and amount of carbon bonds, qualitative the particle size of the titanium dioxide or zinc oxide determines which parts of the electromagnetic spectrum it absorbs. There is a strong belief that these inorganic metal oxide sunscreens act by reflecting uv light instead of absorbing it, but this isnt the complete story. Uv light is divided into uvb and uva. Uvb is between 280 to 315 or 320 nm and uva is between 315 or 320 to 400. Inorganic sunscreens predominately absorb in the uvb spectrum and reflect in the long uva (above 360 nm) and visible spectrum.

The energy from uv light promotes electrons in the conjugated carbon bonds of organic sunscreen molecules from a lower energy state to a higher energy excited state. The excited electrons in the bonds then relax or release the absorbed energy by stretching, vibrating, or bending this turns that energy into heat. In some cases, the organic sunscreen chemical cant relax and release the absorbed energy by bending, stretching, or vibrating and the absorbed energy causes a change in its structure. This is what happens with avobenzone, it absorbs the uv energy and instead of relaxing, it changes its structure and this new structure formed from avobenzone doesnt absorb uv energy as well. As more and more avobenzone molecules structures change, the less uv energy is absorbed by the sunscreen formula. Some writing of the new structures formed from avobenzone are also more irritating and sensitising to the skin. Photo-stabilizers prevent this from happening by absorbing the energy from excited avobenzone and releasing it before its structure can change. Inorganic sunscreens work very similarly even though their structure is different from organic sunscreens.

Inorganic and organic neatly divide the two sunscreen types and are also descriptive. I know most companies wont want to confuse their customers by labelling their 80 organic-certified sunscreen product with titanium dioxide as inorganic, but at least as sunscreen shoppers we can understand the difference! Inorganic sunscreen and organic sunscreens work differently mostly myth! Its often said that inorganic sunscreens (titanium dioxide and zinc oxide) reflect uv off of the skin and organic sunscreens absorb uv and convert it into heat. In reality, for most of the uv spectrum they work very similarly. Organic sunscreens absorb uv because of the way the bonds between their carbon molecules are arranged. The number of bonds between the carbon atoms in the sunscreen molecules and their conjugated arrangement give sunscreens their absorptive properties in the uv region of the electromagnetic spectrum. Remember that conjugated means alternating single and double bonds!

Well, theyre both metal oxides or metals combined with oxygen. Metal oxide sunscreen doesnt have the alinsky same ring to it, but there is another way to describe them. Organic, in marketing, organic is a label that describes how something is produced often with a safe-list of chemical treatments and approved practices. In chemistry, organic means the chemistry of compounds that contain carbon. Titanium dioxide and zinc oxide dont contain carbon. Theyre made up of metal and oxygen and classified as inorganic. Marking thesis the categories as organic and inorganic makes more sense because all of the sunscreen chemicals used contain carbon, except for titanium dioxide and zinc oxide.

If you look at the chemical structure of an organic sunscreen like avobenzone youll see that they have single bonds alternated with double bonds. This alternation or conjugation of the single and double bonds allows the molecule to absorb energy along the electromagnetic spectrum. The amount of conjugation determines which part of the electromagnetic spectrum they absorb, whether that be in the visible spectrum to produce a colour, or in the ultraviolet spectrum to protect our skin from.

These are myths and are not backed by research or chemical knowledge. By following these rules (or myths) youre not using your sunscreen to its greatest effect! Dividing sunscreens into physical and chemical isnt the best way to. These two categories overlap completely. If we were to draw a venn diagram of the two groups, itd look like this.


Chemicals are physical they have a mass and take up space. On the other end, the physical sunscreens titanium dioxide and zinc oxide are chemicals, you can find the elements titanium and zinc on the periodic table. Its sometimes explained that titanium dioxide and zinc oxide are suspensions of particles, they dont dissolve or form solutions like chemical sunscreens. This is true and their even distribution in the sunscreen formula and on the skin is very important poor distribution can greatly reduce how much uv protection titanium dioxide or zinc oxide can provide on the skin. However, there are caveats, sunscreens like tinosorb M (inci: Methylene bis-Benzotriazolyl Tetramethylbutylphenol) also exist as particle suspensions not solutions. Tinosorb M comes as a very fine suspension of particles in water. So, if you were to draw the line based on that youd have to include tinosorb M,  a chemical sunscreen with the physical sunscreens. What does differentiate titanium dioxide and zinc oxide then?

Question for you: How do you teach students to tell the difference between fact and opinion? Titanium dioxide and zinc oxide are often categorised as physical sunscreens, whereas every other sunscreen used is considered a chemical sunscreen. Physical Sunscreens, chemical Sunscreens, zinc Oxide, titanium dioxide. Octocrylene, avobenzone, octinoxate, octisalate, statement oxybenzone, homosalate, mexoryl. Mexoryl xl, tinosorb s, tinosorb m, youll often find different rules and advice for using physical and chemical sunscreens. One dermatologist says that you need to apply less physical sunscreen compared to a chemical sunscreen. Theres also the belief that physical sunscreens provide protection instantly, dont resume absorb into the skin, dont degrade in the sun, and dont need reapplication.

How do the two writers portray the subject in a different light? Watch a clip from a presidential debate and have small groups choose three statements made by each candidate to research further. Are the statements factual? If not, why do students think the candidates chose to include that information? In Grades 912: go lab on a twitter scavenger hunt, where students analyze the last several tweets of a politician, writer or other figure and decide which are facts and which are opinions, performing additional research if necessary. Challenge students to bring in examples of opinions that are presented as facts from news stories, blog posts or elsewhere online. Discuss how and why the writer made the choice to convey the information the way that he or she did.

facts and which are opinions. In Grades 35: teach students about opinion trigger words, such as believe, think feel, always, never and none. Invite students to search for these words in newspaper editorials and in regular articles. Which kinds of stories have more opinion trigger words? Study examples of persuasive writing and show students how writers use facts to support their opinions by highlighting opinions in one color and supporting facts in another. In Grades 68: Discuss how nonfiction writers bring their own biases and opinions to what they write. You might read two picture book biographies of the same person to illustrate this point.

They simply sound the same when spoken. Later we'll talk about the texting version "UR".(God, it's like the English language had a bastard child - and its name is "TXT".). As a busy election season always seems to demonstrate, learning how to tell fact. Opinion is not only a skill that will serve students across the curriculum and on standardized tests, but also throughout their lives. This is especially true in an information-driven world where anyone can disseminate facts via tweets, wikipedia entries or blog posts. With that in mind, here are some of our favorite ways to teach this valuable skill at every grade level. In Grades K2: Write simple facts and opinions on strips of paper, such as Ice cream is made of milk and sugar and Vanilla ice cream is the best. Have students sort the strips into two piles, true for everyone eksempel and not true for everyone.

Let me begin this article by stating a fact: i am not an English major or an expert on the language. Let me also state another fact: you don't have to be an expert to understand the difference between "your" and "you're". These, as we shall discover, are two commonly mixed up and misused words that quite frankly, tick me off. They both sound the same when spoken. However, they mean completely different things when written. Some other words like "lead" are written the same way, but spoken differently and have very different meanings (i.e., as a verb to show someone to a destination, or as a noun in the case of from the element with an atomic number of 82). The meaning is defined by the context of what you are reading. you're " and "y our however, cannot be interchanged when writing because they are spelled differently and mean completely different things.
