Abstract
We describe a process for perfuming fabrics washed in the presence of a lipase-containing detergent and, optionally, subsequently treated with a fabric softener, said process being characterized in that said detergent and/or said fabric softener contains a compound of formula ##STR1## wherein a. R represents a radical derived from an fragrant alcohol of formula ROH and Y represents a C.sub.7 to C.sub.24 linear or branched, saturated or unsaturated alkyl radical, or a --(CH.sub.2).sub.n COOR group wherein R is defined as above and n is an integer from 0 to 6; or PA1 b. Y represents a C.sub.7 to C.sub.24 linear or branched, saturated or unsaturated alkyl radical and R represents a group of formula ##STR2## wherein, either R.sup.1 represents hydrogen and R.sup.2 represents an alkylidene radical derived from a fragrant aldehyde of formula ##STR3## or R.sup.2 represents an alkylidene radical and R.sup.1 an alkyl radical, R.sup.1 and R.sup.2 being then derived from an fragrant ketone of formula ##STR4## and, optionally, being part of a ring such as indicated by the dotted line which contains 5 to 18 carbon atoms and can be substituted. The process has the advantage of providing an effect…
