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 p1 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 of slow diffusion ("slow release") of said fragrant alcohol, aldehyde or ketone, thus prolonging the odor effect of the latter on fabrics.
