Going outside at 11 o’clock? Have you worn sunscreen?

Cinoxate

Cinoxate is an organic compound used as an ingredient in some types of sunscreens. It is a slightly yellow viscous liquid that is insoluble in water, but miscible with alcohols, esters, and vegetable oils. It protects skin against the sun by absorbing UV-A and UV-B rays.

Trolamine salicylate

Trolamine salicylate is used as an ingredient in sunscreens, analgesic creams and cosmetics. The salicylic acid portion contributes to both the sun protection effect (by absorbing UVB radiation) and to the analgesic effect. The triethanolamine neutralizes the acidity of the salicylic acid. One benefit of this topical analgesic is that it has no odour, in contrast to other topical analgesics such as menthol.

Homosalate

Homosalate is an organic compound used in some sunscreens. Homosalate is present in 45% of U.S. sunscreens. It is used as a chemical UV filter. The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295 nm to 315 nm, protecting the skin from sun damage. The hydrophobic trimethylcyclohexane functional group provides greasiness that prevents it from dissolving in water.
