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 Insect Repellent DEET | Pesticides | US EPA - 2 views

www.epa.gov/...deet.htm

shared by Katie Rigdon on 12 Dec 12 - No Cached

After completing a comprehensive re-assessment of DEET, EPA concluded that, as long as consumers follow label directions and take proper precautions, insect repellents containing DEET do not present a health concern. Human exposure is expected to be brief, and long-term exposure is not expected. Based on extensive toxicity testing, the Agency believes that the normal use of DEET does not present a health concern to the general population. EPA completed this review and issued its reregistration decision (called a RED) in 1998. (More about REDs)

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!

Sunscreen (also known as sunblock) is a lotion, spray or other topical product that helps protect the skin from the sun's ultraviolet (UV) radiation, and which reduces sunburn and other skin damage, ultimately leading to a lower risk of skin cancer.

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 thought this article was really interesting as it talks about how different sunscreens differ from each other based on the frequencies of light they absorb.

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!

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.

Interesting article about causes of skin allergies from WebMD. Looks like fragrances can play a big part in allergies and it also looks like there are some things that you can do to prevent these allergic reactions.
