Product Information

Wash your hands with plenty of dish soap and warm water for 30seconds. While washing, thoroughly rub your hands free of sunscreen. Then rinse your hands with rubbing alcohol and dry them with paper towels. vc_row full_width=”stretch_row_content”][vc_column][vc_single_image image=”28506″ img_size=”full” alignment=”center”][/vc_column][/vc_row][vc_row full_width=”stretch_row” fullwidth=”true” fullwidth_content=”false” css=”.vc_custom_1549033832259{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column width=”1/6″][/vc_column][vc_column width=”2/3″][vc_custom_heading text=”Here, you’ll find all the information you need to take the first steps in being a Solar Buddies supplier.” font_container=”tag:h3|font_size:32px|text_align:center|line_height:38px” use_theme_fonts=”yes”][vc_column_text] You will prepare a set of standards containing different concentrations of sunscreen. The UV meter readings for each standard will change depending on the amount of sunscreen in the water sample. Based on the Beer-Lambert law, the relationship between the sample's absorbance and the sunscreen concentration should be linear. This linear relationship will allow you to calculate the sunscreen concentration of your unknown sample. Solar Buddies are unique because they are a refillable applicator that allows you to use a sunscreen of your choice. They are easy to use, with less mess and no waste. There’s always a slight risk of contamination when transferring products from one container to another. To minimize this risk, always use clean tools and bottles, and avoid touching the lotion directly with your hands

Set a timer for one minute and start it. Then swirl the water around in the bag. Make sure the water covers your finger. This simulates entering the water 7minutes after applying sunscreen. Chemical sunscreen containing at least one of the following ingredients: avobenzone, homosalate, octisalate, or octocrylene. Should be a lotion (not a spray) and have the same SPF as the physical sunscreen. Set a timer for one minute and start it. Then swirl the water around in the bag. Make sure the water covers your finger. This simulates entering the water 15minutes after applying sunscreen. The results of this science project told you how much sunscreen got from your pointer finger into the water sample—and the number might seem very small to you. However, you are not only putting your pointer finger in the water when swimming in the ocean—you go into the water with your whole body! Can you extrapolate from your results how much sunscreen would get into the water from your whole body? How does the surface area of the pointer finger relate to the surface area of your body? You also need to take into account how much of your body you actually put sunscreen on.

This standard is a 1:10 dilution of standard #2 and has a sunscreen concentration of 0.003g per 10mL water. Figure 3. Physical sunscreen (left) reflects UV light, whereas chemical sunscreen (right) absorbs UV light and transforms it into harmless radiation. On the right is the same setup from the side. The cuvette is held right against the UV sensor with minimal space in between. Whisky connoisseurs Stephen and Jacqueline Pyne from Scotch Galore Whiskies were next in the Den. They provide a free-to-use online platform for buying and selling whisky, earning a small commission on each exchange. After a muddling explanation of the finances and concerns expressed about a limitation on potential profit, all of the Dragons were out, recommending that this is a great business exactly as it is. To a happy and hopeful Series 21

This standard is a 1:2 dilution of standard #5 and has a sunscreen concentration of 0.0015g per 10mL waterThis was a great result for the Solar Buddies entrepreneurs. I’m now personally excited to see these sunscreen applicators on the shelves this summer! It is important to note that with the UV meter you do not directly measure the absorbance of your sample. Absorbance means how much light gets absorbed by your sample. What you measure with the UV meter is the amount of light passing through the sample, which is called transmittance. The absorbance has a logarithmic relationship to the transmittance. You can use Equation 2 to convert a value from percent transmittance (%T) to absorbance. Figure 4. Setup (not to scale) for measuring your samples. The UV radiation from the sun passes through your water sample before it hits the UV sensor. Since it also passes through the sides of the vessels holding the sample, those vessels need to be standardized. Cuvettes,—which are clear, flat, and 1cm wide—are designed precisely for this application.
