senseschemical

Senseschemical is a neologism used to describe chemicals that interact with the senses or the study of such interactions. It can refer to individual chemical compounds that influence perception—such as odorants, tastants, and irritants—and to a broader field concerned with how chemicals shape perception and behavior. The term is not widely established in formal literature, but it appears in discussions of chemosensation, sensory science, and product development as a concise way to reference the chemical basis of sensation.

Chemicals central to senses include odorants that bind to olfactory receptors to produce smell, tastants that stimulate gustatory receptors to evoke taste, and irritants that activate the trigeminal system, contributing to chemesthesis. In vision, photochemical processes in the retina underlie color and brightness, illustrating how chemistry underpins multiple sensory modalities.

Applications span fragrance and flavor design, food science, and pharmacology, as well as neuroscientific and ecological research into chemical communication. By studying the properties and perceptual effects of these chemicals, researchers seek to predict sensory outcomes, optimize consumer experiences, and understand safety and regulatory considerations across industries.
