Isoamyl P-Methoxycinnamate
What is Isoamyl P-Methoxycinnamate?
Isoamyl p-methoxycinnamate is a synthetic organic compound from the cinnamate class of ultraviolet filters. Chemically, it is the isoamyl ester of p-methoxycinnamic acid, created through esterification. It belongs to the sun protection category in cosmetics, commonly found in lotions, creams, and sprays. This oil-soluble ingredient works by selectively absorbing UVB rays in the 290-320 nm range. When UV photons strike the molecule, it enters an excited state and releases the energy as harmless heat, blocking radiation from reaching skin cells. This mechanism helps mitigate UV-induced effects without reflecting light like physical blockers. It integrates well into formulations for even coverage and is often paired with other filters for enhanced protection across UV spectra.
