| abstract |
Fragrances having a fresh odor are usually very volatile and are therefore not very economical when used in typical applications such as e.g. washing or cleaning processes. They therefore have to be used in relatively large quantities to be able to produce adequate effects. The invention relates to certain ketones as photolabile pro-fragrances which have a greatly improved stability of the scent impression, especially the fresh odor, in typical applications. The invention further relates to corresponding detergents and cleaning agents, air cleaning products and to a method for scenting surfaces. |
