Homosalate

Homosalate is a synthetic organic UV filter that primarily absorbs UVB radiation (wavelength range 290-315 nm). It's an ester formed from salicylic acid and 3,3,5-trimethylcyclohexanol, creating an oil-soluble compound that's particularly valued for its excellent solubilizing properties for other UV filters. Formulators choose homosalate not only for its sun protection capabilities but also because it helps dissolve and stabilize other sunscreen actives in formulations, often allowing for higher SPF values while maintaining elegant, non-greasy textures.
