Abstract: Photolabile pro-fragrances may include the ketones of Formula (I) Such compounds may be used in detergents, cleaning agents, cosmetic agents, air-care agents, and combinations thereof. The photolabile pro-fragrances may create a long-lasting fragrance on surfaces or in a room using the aforementioned pro-fragrances.

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: The present invention relates to the field of fragrance storage means as used, for example, in the field of washing or cleaning compositions, cosmetic compositions and air freshening compositions. The invention relates to specific diazirines which function as thermally labile and acid-labile fragrance storage means. The present invention further relates to washing and cleaning compositions, cosmetic compositions and air freshening compositions comprising such diazirines. The invention further relates to a method of long-lasting fragrancing of surfaces, and likewise to a method of long-lasting room fragrancing.

Abstract: The invention relates to specific ketones of formula (I) which act as photolabile pro-fragrances. The invention also relates to detergents or cleaning agents, cosmetic agents and air fresheners including such ketones. The invention further relates to a method for creating a long-lasting fragrance on surfaces and also to a method for creating a long-lasting fragrance in a room using the aforementioned ketones.

Abstract: A method for producing photo-cleavable fragrance pre-cursors is described, which includes potential stereoselective method steps, agents containing the fragrance pre-cursors and the use of the fragrance pre-cursors for prolonging the scent impression in the agent and on surfaces treated with said agent.

Abstract: The invention relates to specific ketones of formula (I) which act as photolabile pro-fragrances. The invention further relates to detergents or cleaning agents, cosmetic agents and air freshening products including ketones of said type. The invention also relates to a method for lastingly scenting surfaces and a method for lastingly fragrancing rooms using said ketones.

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: Fragrances that provide a scent of freshness tend to be volatile and are therefore not very economical when used in typical applications such as washing or cleaning processes, so they have to be used in relatively large quantities to be able to produce adequate effects. The disclosed photolabile pro-fragrances provide a much longer-lasting sense of fragrance, in particular with a scent of freshness, when used in typical applications, thus allowing said fragrances to be used economically.

Abstract: The present invention relates to a method for producing photocleavable scent precursors, to products containing the scent precursors, and to the use of the scent precursors for prolonging the scent impression in the product and on surfaces treated with the product.

Abstract: Many fragrances that provide a scent of freshness tend to be highly volatile and are therefore not very economical when used in typical applications such as washing or cleaning processes, so they have to be used in relatively large quantities to be able to produce adequate effects. The disclosed photolabile pro-fragrances provide a much longer-lasting sense of fragrance, in particular with a scent of freshness, when used in typical applications, thus allowing said fragrances to be used efficiently.
