Abstract (en)
[origin: WO2013000669A1] Fragrances having a fresh scent are usually very volatile and therefore not very economical in typical applications, such as washing or cleaning processes. Thus, said fragrances must be used in relatively large quantities, in order to bring about appropriate effects. The invention relates to photolabile pro-fragrances of the formula (I) that facilitate a greatly improved stability of the olfactory impression, in particular a fresh scent, in typical applications. Said pro-fragrances bind very easily to target substrates, such as textiles. Thus, an economical use of the relevant fragrances can be ensured.
