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.

Abstract: Photolabile fragrance storage substances capable of photo-induced release of odorant aldehydes and odorant ketones are described in addition to a process for long-lasting fragrancing of surfaces and a process for producing said fragrance storage substances.

Abstract: Fragrances having a fresh character are usually very volatile and therefore not very economical in typical applications such as washing or cleaning processes for example. For that reason they have to be used in relatively large amounts in order to bring about appropriate effects. The present invention describes photolabile pro-fragrances that allow for a greatly improved persistence of the fragrance impression, in particular one having a fresh character, in typical applications. A more economical use of the fragrances in question can be ensured in this way.

Abstract: Fragrances having a fresh character are usually very volatile and therefore not very economical in typical applications such as washing or cleaning processes for example. For that reason they have to be used in relatively large amounts in order to bring about appropriate effects. The present invention describes photolabile pro-fragrances of formula (I) that allow for a greatly improved persistence of the fragrance impression, in particular one having a fresh character, in typical applications. Said pro-fragrances attach very readily to target substrates, such as textiles for example. A more economical use of the fragrances in question can be ensured in this way.

Abstract: Scents having a fresh odor are usually very volatile, and therefore have a low yield in typical applications such as washing or cleaning processes. They must therefore be used in relatively large quantities so that commensurate effects can be achieved. The invention describes specific ketones as photolabile scent storage substances which enable greatly improved persistence of the scent impression, in particular with a fresh odor, in typical applications. Corresponding washing or cleaning agents and air freshening agents, and a method for scenting surfaces, are also described.
