The Full Story

Aldehyde C-18 (gamma-nonalactone, CAS 104-61-0) is a nine-carbon gamma-lactone. At low concentrations: creamy-milky. At medium: unmistakable coconut. At high: waxy and fatty.

Found naturally in coconut, peach, raspberry, dairy. The molecule most responsible for the sunscreen association in Western culture.
