Abstract

Photolabile scent storage substance that are capable of photoinduced release of cyclic compounds have at least one cyclic double bond. These scent storage substances are special ketones, and enable greatly improved stability of the scent impression, in particular with a fresh character, in typical applications, for example in textile laundering, room scenting, and in the cosmetic sector. More economical utilization of the stored scents can thereby be ensured. Also described are corresponding washing or cleaning agents, scenting methods, and methods for manufacturing the special ketones.
