What is Homosalate?

Homosalate, chemically known as 3,3,5-trimethylcyclohexyl salicylate, is a synthetic organic compound derived from salicylic acid and a cyclohexanol derivative. It belongs to the salicylate class of chemical sunscreens, commonly used in sun protection products. As an oil-soluble ingredient, it penetrates the skin's upper layers and absorbs ultraviolet B (UVB) radiation in the 295-315 nm range, converting it into harmless heat to shield skin from sun-induced damage. Beyond sun protection, it serves as a fragrance component to stabilize scents and mask odors, while its emollient properties help maintain skin's moisture barrier, promoting softness. Typically incorporated into lotions, creams, and sprays at regulated levels by authorities like the FDA and EU.
