Sunscreen is a staple in any household and with a variety of varying brands and SPF values it can be difficult to decipher which is the best choice. UV-visible spectrophotometry is one useful analytic method to compare the effectiveness of differing sunscreen samples. Absorbance of UVB and UVA radiation can be compared between the sunscreens by looking in the wavelength ranges of 290 to 320 nm (UVB) and 320 to 400 nm (UVA). Between the four varying sunscreens (Up & Up SPF 30 and 50 and Banana Boat SPF 30 and 50), the Up & Up SPF 50 showed greatest absorbance at all wavelength values. Submitted as part of the CHE-300 Analytical Chemistry course.
