Yes its safe to decant sunscreen from one container to another as long as you ensure the original and the new bottle are clean from contaminents however, there are some precautions to consider The sun is on the left. In the middle, a blue rectangle represents a cuvette filled with sample. On the right, an orange box represents the UV meter. A yellow line from the sun to the UV meter represents the sunlight shining on the UV sensor. The line color gets lighter after passing through the cuvette due to UV light absorption of the sample. The Physics Classroom (n.d.). The Electromagnetic and Visible Spectra. Retrieved February 21, 2023.Add 0.3g of the mineral sunscreen containing zinc oxide or titanium dioxide to the cup labeled "physical sunscreen."

The main focus of this science project will be to test how much of the potentially harmful chemicals in sunscreens get from your skin into the water at different intervals after sunscreen application. We can use this information as a proxy for how eco-friendly or reef-safe the products are. This standard is a 1:2 dilution of standard #5 and has a sunscreen concentration of 0.0015g per 10mL water Kelli and Laura worked with Cardiff Metropolitan University to come up with the design. When businesses have this sort of relationship with an academic organisation, it’s likely there would be some sort of IP ownership agreement and/or non-disclosure agreement in place.Use the spreadsheet program to add a linear trendline to your data. Display the correlation factor R 2 and the equation of the trendline in your plot. Note:The correlation factor tells you how well the trendline matches your data. A perfect fit is 1. Your correlation factor should be at least 0.9. If this is not the case, you might have made some mistakes while preparing your standard solutions or during your measurements. Repeat your measurements or make new standard solutions until you achieve a correlation factor greater than 0.9 before continuing your data analysis. This standard is a 1:2 dilution of standard #2 and has a sunscreen concentration of 0.015g per 10mL water. 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. The UV index ranges described start at 0 to 2, which is considered low-risk, with an estimate of 60 minutes to sunburn and a recommendation of sunscreen with SPF 15. At the high end of the scale, a UV of 10+ carries extreme risk, with only 10 minutes to sunburn. Recommendations at this level include sunglasses, cover up and hat, sunscreen with SPF 50+, and avoiding the sun from 11 a.m. to 5 p.m.

Chemical sunscreen uses different active ingredients. These can include avobenzone, homosalate, octocrylene, and octisalate. When chemical sunscreen is applied, these chemicals penetrate the skin. Once there, they absorb harmful UV radiation and transform it into non-damaging radiation or heat, as shown in Figure 3 on the right. Because the UV-absorbing chemicals need time to penetrate the skin, it is important to apply chemical sunscreen at least 15 minutes before sun exposure. One benefit of chemical sunscreens is that they do not leave a white layer on your skin like mineral sunscreens do. As discussed in this project, there are many different UV-absorbing sunscreen chemicals. Some of them have already been banned in several locations. Take a closer look at all the active ingredients in chemical or physical sunscreens. Do some research to find out what their function is and if there are any health or toxicity issues associated with them. What do your water solubility results mean regarding the eco-friendliness or reef safety of the different types of sunscreens? Although Jo Proud’s business was straightforward, it was one of the most heartwarming pitches of the entire series. Teddy bears that represent different moods and emotions captured the hearts of the fire-breathing dragons so much that when Peter Jones suggested the five join forces to become a mega dragon and invest in Proud’s Mood Bears, they all heartily agreed.Once you have a good calibration curve, you can use the trendline equation to calculate the sunscreen concentration of your samples. Because you plotted absorbance on the y-axis, the "y" in your trendline equation represents the absorbance of your measured sample. The "x" of your trendline equation represents the sunscreen concentration of your sample, since you plotted the sunscreen concentration on the x-axis. The cuvettes contain milky-white sunscreen solutions, with the highest concentration on the left and the lowest concentration on the right. This standard is a 1:10 dilution of standard #2 and has a sunscreen concentration of 0.003g per 10mL water.

As an IPO Associate Patent Examiner myself, I was really impressed when Laura went straight into asserting that they have a granted UK patent ( GB2531771B) and an international patent pending ( WO2023007111) covering the sponge and rollerball partnership. So where’s the IP in Solar Buddies’ 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.
