Homosalate is an organic compound used in some sunscreens. It is made by the Fischer–Speier esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, the latter being a hydrogenated derivative of isophorone. Contained in 45% of U.S. sunscreens, it is used as a chemical UV filter.[3] The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295nm to 315nm, protecting the skin from sun damage. The hydrophobic trimethyl cyclohexane f...
