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.
具有清新气味的香味通常非常挥发,因此在洗涤或清洁过程等典型应用中产量较低。因此,必须使用相对较大的量,以达到相应的效果。该发明描述了特定的
酮类作为光敏香味储存物质,从而在典型应用中特别是具有清新气味的情况下,实现了香味印象的大大改善。还描述了相应的洗涤剂、清洁剂和空气清新剂,以及一种用于给表面添加香味的方法。
