    Here is one organization fighting animal testing. It is interesting that they point our that animal testing is still used even though it supplies results that are not always applicable to humans. I think this could be a really interesting blog topic!

    The entire premise of animal testing is and has been a hot topic for a while now. It poses big ethics questions that can be looked into. However, there was something in the article that said that even if a product blinds an animal, it sometimes is still sold to humans, which raises the question of whether or not animal testing even has a purpose anymore.
  • Jenny Mu on 17 Dec 12
     
    Animal testing is pretty big in the cosmetic world, but we definitely need to relate it back to chemistry some how. I think if we find some sort of connection to chemistry, then we're golden :)
  • Andrew Kang on 18 Dec 12
     
    well in the real world no field of science stands on its own. it is always interwoven with other fields, like chemistry and biology especially since we're looking at cosmetics. this article seems mostly ethics/biology concerned so i don't know how relevant it will be :/
  • Amanda Jara on 18 Dec 12
     
    Yeah, you have a point. But wasn't there a part of the project that we needed to include that related to a field other then chemistry?
  • Amanda Jara on 18 Dec 12
     
    If worse come to worst, we can always relate how an animal absorbs the cosmetics' chemicals differently than humans do (relating it back to chemistry).
  • Andrew Kang on 19 Dec 12
     
    true true so this covers the whole "relating to other fields" topic. and animal chemistry (is there such a thing?) is definitely worth looking at.

    Amanda - this might help with your blog post on colors in makeup
  • Amanda Jara on 26 Nov 12
     
    Yeah this is great! It's really interesting to see what goes into making the different colors. It's amazing how different the same product can be just because it has a different color.
  • Jenny Mu on 27 Nov 12
     
    that's a good point, that maybe you have the same eyeshadow in different colors, yet each of those different colors is actually made up of different stuff. It kind of makes you think... is there one color that is better than the rest because of its components? hmm...
  • Katie Rigdon on 28 Nov 12
     
    I saw your tweet about crushed beatles and I think I saw the same article when I was doing some research on the same topic too! It's really interesting, apparently the FDA has to approve color additives. This (http://www.fda.gov/forindustry/coloradditives/coloradditiveinventories/ucm115641.htm) is an extensive list of all the color additives they have approved so you might be able to get some good information from there. The FDA website in general has a lot of really great resources for our blog.
  • Jenny Mu on 28 Nov 12
     
    *beetles not beatles. Haha we don't want crushed brit bands in our cosmetics :) yeah that's a really interesting page. I think I just spent the last 10 minutes scrolling through all the things and picking out the ones that I recognized from the back of food wrappers. But I wish they would put what color the additive is, so you can see what colors go into your products. But maybe they didn't put the color because it changes based on the chemistry of the item that it's going into? that could be interesting to look into...
  • Katie Rigdon on 01 Dec 12
     
    haha sorry about that typo :) oh and I'm pretty sure I found a page that lists what color it is. Let me see if I can find it again.

  • Katie Rigdon on 11 Dec 12
     
    The chemistry behind soaps could be a really interesting topic. I know in AP Chemistry we were talking about how some soaps just remove the oils on your skin, but it is also really important for soaps to moisturize your skin as well as clean it so that your skin doesn't get really dry.
  • Katie Rigdon on 11 Dec 12
     
    Sorry I just realized that that last comment wasn't totally related to the article but it is another aspect of soaps that we could look into. It could also be interesting to compare the ingredients of different soaps and see if the differences really affect their performance.
  • Andrew Kang on 12 Dec 12
     
    It's not related to this article but it is related to what we're learning in class/cosmetics - I smell a possible blog post.
  • Amanda Jara on 14 Dec 12
     
    Going off of what Katie said about soaps removing the oils on you skin, I know some people who have really sensitive skin and actually break out into rashes after using certain soaps. Maybe we can look why that happens, (is it the removal of oils, or the addition of chemicals that are supposed to help moisturize the skin). From there we can probably find the ingredient that leads to such effects.
  • Andrew Kang on 14 Dec 12
     
    That's a good idea - the "or." Perhaps it is actually both? And these ingredients that supposedly help moisturize your skin, how are they passing testing if they dry it out? Things to look into.
  • Katie Rigdon on 16 Dec 12
     
    It looks like a this topic could really tie in with the last topic in advanced chem in terms of polar and non-polar molecules. Yay connections :)
  • Amanda Jara on 16 Dec 12
     
    Maybe we can go even further and see if it is the different combinations of ingredients that causes reactions. Perhaps it may be the case that one ingredient may be harmless if it is alone, but when combined with something else, it can change its properties.
  • Jenny Mu on 17 Dec 12
     
    I'm in the process of writing a blog post on soaps, and iin my research, I basically found that soaps are made from fats and salts, which make the non polar and polar, and so that lets them bind to non polar things like grease and polar things like water, and they lets them wash stuff away. Thats a way we can relate this to the stuff we're learning in class :)

chemistry moisturizer skin emulsions

shared by Katie Rigdon on 29 Nov 12 - No Cached
  • Katie Rigdon on 30 Nov 12
     
    Hey guys so the interesting aspect of this article is the part about emulsions. Emulsions are basically mixtures of water, oil, and surfactant (something that binds to both oil and water and therefore helps them combine). This topic is interesting in terms of moisturizers because your skin needs oil to moisturizer it but just putting oil on our skin is very messy. Emulsions allow for neat and tidy moisturizers for our skin!
  • Jenny Mu on 19 Dec 12
     
    So bringing back an old article, do you guys think we could relate this to what we're learning in class by looking at the process of mixing water, oil, and surfactant. Because water and oil naturally repel, do you guys think that getting them to mix together would be an endothermic reaction, because thats not how they want to be? Just a random thought :D

    The radiation that comes from the sun, known as the solar spectrum, contains the visible sunlight that we see as well as invisible components of "light." The different parts of the solar spectrum have different wavelengths. Some of the solar spectrum is blocked by the earth's atmosphere, including the ozone layer that people are concerned about losing.

    I think I will write my next blog post on this topic so I am going to post a few more links and let me know what you guys think!
  • Jenny Mu on 26 Nov 12
     
    relating it to chemistry, it would be interesting to look at the different chemical compounds and which one help deflect which uv rays. I think this site mentions para-amino benzoic acids, zinc oxide, and titanium oxide.
  • Andrew Kang on 28 Nov 12
     
    everyone knows that there's chemistry behind sunscreen but it'd be cool to finally to see HOW the chemistry works! good idea
  • Katie Rigdon on 28 Nov 12
     
    Yeah! It's also kind of interesting because there are two different types of sunscreen: chemical and physical. I can talk about the differences there too!
  • Amanda Jara on 28 Nov 12
     
    I wonder if the sunscreens that created the thick, white 'goo' is stronger and more efficient than the transparent sunscreens used today. Most bottles of sunscreen say to reapply within a certain number of hours, so it can be interesting to see how older formulas of sunscreen compare to those most commonly used today.
  • Jenny Mu on 28 Nov 12
     
    That's a really good point, Amanda. Those thick white sunscreens that just show up on your skin opaquely probably helps to protect your skin just by blocking out the sun... Nowadays, since no one wants to have gross, whitish stuff on their face, sunblock has become clear so that you can't see it. I think they protect you from the sun by either absorbing the rays, like with oxybenzones, or reflecting the sun in tiny particles of metal oxides. Changing sunscreen to be transparent was probably for aesthetic reasons, but which way is better for sun protection? Is just straight up blocking out the sun with an opaque covering better or are these new, fancier ways better...
  • Amanda Jara on 29 Nov 12
     
    The Nanomaterials article above mentions something about using smaller particles between 20-200nanometers which make the lotions nearly clear. Because of this, I would hypothesize that it is not as effective. In addition, continuing with this topic, (despite this being from the above article) the nanoparticles seem to have a negative effect on the aquatic life and their environments.
  • Jenny Mu on 30 Nov 12
     
    hmmm interesting that you say that we could tie in environmental effects into one of our blog posts maybe? Perhaps about the chemical compounds in our personal products, and how they affect the environment? I think sunscreen is a big one, because a lot of the time, people just go into the water right after they put it on, so it can come off into the water and affect aquatic life. Good idea

  • ...5 more annotations...
  • Syn-Coll stimulates the collagen synthesis in human fibroblasts. Skin aging and chronic UV exposure particularly, leads to degenerative changes in skin. The degenerative changes in skin are characterized by distinct alterations in the composition of the dermal extra cellular matrix.
  • Tissue growth factor is known as the key element in the synthesis of collagen and binds to a particular sequence in the TSP molecule. This sequence is known as ARG-PHE-LYS.
  • As a molecule able to activate TGF, Syn-Coll is considered to be an ideal aqueous based peptide. It contains a unique sequence designed to mimic the human body's own mechanism to product collagen via TGF. Accordingly, Syn-Coll actively compensates for any collagen deficit, thus making the skin look younger and rejuvenated.
  • The results of the Syn-Coll clinical studies are astounding. After 84 days of twice-daily application, a panel of 60 volunteers experienced 2.5% Syn-Coll parameters average relief (Rz) and maximum relief (Rt) significantly decreased by -12%: -22 μm and -36 μm respectively (p= 0.05) characterizing smoothing and anti wrinkle effects.

    I was actually trying to find an article on the chemical processes behind anti-aging cremes the other day but I haven't found a good one yet.

      The article kept stressing the benefits of colloidal gold as opposed to gold in flakes or just applied to the skin. Perhaps we could look at nanochemistry in cosmetics - it was nanoparticles that gave the colloidal cream its advantage and with anything you apply to your skin perhaps there is consideration given to the substance on the molecular scale for its efficacy.
    • Jenny Mu
      Jenny Mu on 17 Oct 12
       
      But we should also consider the element itself. Whether in nanoparticles or in flakes, what scientific evidence is there that gold is good for the skin? Or is it just one big, expensive scam...

    I think that talking about skin lightening, which is really important in old ladies with dark spots, could be a good blog post. I think this site is really helpful in terms of explaining things thoroughly but in an easyish to understand way too. It appears that because theres a glucose attached to the molecule of arbutin, it makes it much more effective. This kind of relates to chemistry so thats good :D
  • Andrew Kang on 22 Nov 12

  • Katie Rigdon on 28 Nov 12
     
    Wait this is a great article because it really explains the detailed structure of arbutin as well as how it works to lighten skin. The alpha vs beta aspect could also potentially be interesting to expand upon.
  • Amanda Jara on 28 Nov 12
     
    From what I understand by reading it, the glucose added onto the hydroquinone makes it safer. There was also a mention of 'anti-cancer activity' on melanoma cells. This can definitely be expanded upon since it is something so different from everything else researched.

  • Jenny Mu on 12 Dec 12
     
    I like the idea of just looking at how it penetrates the skin, and I think we can relate it back to cosmetics through that because a lot of cosmetic products need to find effective ways to get their ingredients to penetrate the skin, because otherwise, they wouldn't really work. just an idea
  • Amanda Jara on 14 Dec 12
     
    Kind of going off of what Katie said about cosmetics healing the body, you can always find the foundation commercials advertising regenerating ingredients that "take years off your face." it can be a different angle to discuss instead of usual topic of how facial cosmetics cause premature aging.
  • Andrew Kang on 14 Dec 12

  • Amanda Jara on 18 Dec 12
     
    This may seem a little random, but after reading all of these articles, it's a bit unnerving to think that we let preservatives sit on our faces all day long, gathering into our pores and clogging them. From reading this article the word 'inorganic' and 'plastic' stood out to me the most since these are unnatural products that block pores.
  • Jenny Mu on 19 Dec 12
     
    I agree with you, Amanda, that thinking about all the stuff in our cosmetics seems "unnerving". Ignorance is bliss, but now that we are more educated about the chemistry behind cosmetics, its seems really weird to be putting all these strange chemicals on our face. When I read the labels on my products, I used to just think, "wow look at all those chemicals with long names" but now I recognize them and think, "There are pthalates and sodium lauryl sulfates, and all those other dangerous compounds in my shampoo?????"

    This is an easy to read, interesting blog post about the usage of worlds like "hypo-allergenic" and "non-comedogenic" on cosmetics, and what it actually means chemically for products to be labelled with those words. This kind of addresses what we were talking about on the simvastatin article, about cosmetics that can help clear skin Things that are non-comedogenic do not necessarily clear skin, but they do not cause acne. We could start there, looking at chemical compounds in cosmetics that can cause acne and that don't cause acne and then look into how to treat it.
