wherein R.sub.1 through R.sub.4 is independently H or methyl; and
R.sub.5 is a branched or linear, saturated or unsaturated C.sub.3-C.sub.7 alkyl, alkenyl, cycloalkyl or cycloalkenyl residue,
as perfume ingredients in personal care and household care products.

A fragrance precursor of 3-(4-isobutyl-2-methyl phenyl)propanal, comprising at least an enamine and/or an aminal as reaction product of 3-(4-isobutyl-2-methylphenyl)propanal (compound according to formula (I)) and a primary and/or secondary amine ##STR00001##
useful as a perfume ingredient.

The present invention relates to use of at least one compound of formula (I) as aroma ingredient. The compound of formula (I) is used to impart an aroma impression which is reminiscent of a sweet note, technical note, tobacco note, balsamic note, herbal note, fruity note, woody note, pine needle note, eucalyptus note, powdery note, or a combination of two or more notes to a composition and also enhancing and/or modifying the aroma of a composition. The present invention is further directed to a composition comprising compound of formula (I) and (i) at least one aroma chemical different from compound of formula (I) or (ii) at least one non-aroma chemical carrier, or (iii) both (i) and (ii).

The present invention relates to the use as perfuming ingredient, in particular to confer odor notes of the violet, violet leaves type, of a compound of formula (I), wherein n represents 1 or 2, A represents CH.sub.2 or CO; and R represents a C.sub.1-4 alkyl or alkenyl group or a C.sub.3 cycloalkyl group, or when A is a CH.sub.2 group R may also represent a C.sub.1-3 acyl group. Moreover, following what is mentioned herein, the present invention comprises the invention's compound as part of a perfuming composition or of a perfuming consumer product. ##STR00001##
