Definitions
- the present invention is in the field of fragrance storage materials, as they are used for example in the field of detergents or cleaners, cosmetics and air care products.
- the invention relates to specific cyclic ketals which function as fragrance storage materials.
- the present invention relates to detergents and cleaners, cosmetics and
- Air care products containing such ketals It also relates to a process for the long-lasting scenting of surfaces.
- fragrances that give the products a pleasant smell. In most cases, the fragrances mask the odor of the other ingredients, resulting in a pleasant odor impression for the consumer.
- Fragrances are important constituents of the formulation, especially in the detergent sector, since the laundry should have a pleasant and fresh fragrance both in the moist and in the dry state. Basically, the use of fragrances involves the problem that fragrances are more or less volatile compounds, but a long-lasting scent effect is desired. Especially with fragrances that represent the fresh and light notes of the perfume and evaporate very quickly due to their relatively high vapor pressure, the desired longevity of the fragrance impression is hardly achievable.
- Fragrance storage molecule for example, are hydrolysis or photolabile, are known in the art and provide a way to release fragrances delayed. Environmental factors induce breakage of a covalent bond in the fragrance storage molecule, releasing a fragrance.
- Ketals are known in the art as fragrances and perfume precursors, so-called profragrances. Ketals as fragrances are disclosed, for example, in International Patent Publication WO 2014/183883 A1. The cyclic ketals described therein act directly as fragrances with amber smell. However, fragrance precursors which release the actual fragrance molecule by hydrolysis of the ketals are not mentioned.
- German patent application DE 19718537 A1 describes depot preparations for the targeted release of fragrance, which are obtainable by the reaction of fragrance aldehydes or ketones with polyhydroxy compounds.
- fragrance intensity is low when using many known fragrance storage molecules and the fragrance effect only for a short time. Therefore, there is still a need for alternative fragrance storage molecules that effectively release fragrance and have a sufficiently high fragrance intensity.
