Infobox disclaimer and references

Homosalate is an organic compound used in some sunscreens. It is an ester formed from salicylic acid and 3,3,5-trimethylcyclohexanol, a derivative of cyclohexanol. It is found in many Coppertone products.

Additional recommended knowledge

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 cyclohexanol portion provides greasiness that prevents it from dissolving in water.
