Sunscreen soap and UV radiationFeatured science projectScience project video

Observation

It  was observed that  increasing the concentration of the Octyl Salicylate in the soap used to coat the glass surface resulted in increasingly lower UV index readings. This means that increased concentrations of Octyl Salicylate resulted in more effective blockage of UV radiation.
