Abstract: Use of aldehyde compounds (I) or their mixtures containing at least one compound (I) or at least two compounds (I), as a perfume with a lily of the valley-note, as an agent for increasing substantivity and/or retention of a perfume composition and/or as a fixative, is claimed. Use of aldehyde compounds of formula (I) or their mixtures containing at least one compound (I) or at least two compounds (I), as a perfume with a lily of the valley-note, as an agent for increasing substantivity and/or retention of a perfume composition and/or as a fixative, is claimed. n : 0 or 1; either R1, R2 : 4-9C alkyl (linear and saturated); or R1+R2+C that is arranged between R1 and R2 : cyclohexyl moiety of formula (IIa); and R3-R5 : H, CH 3, ethyl, isopropyl or tert-butyl; or R1 : H; and R2 : 4-9C alkyl (branched and saturated), (IIa) or phenyl moiety of formula (IIb); and R3-R5 : H, CH 3, ethyl or isopropyl (when n = 1); or R1+R2+C that is arranged between R1 and R2 : (IIb); and R3-R5 : H, CH 3, ethyl, isopropyl or tert-butyl (when n = 0); and a, b : bond that connects (IIa) with adjacent O (when R1+R2+C = (IIa)), bond that connects (IIa) with adjacent C (when R2 = (IIa)), bond that connects (IIb) with adjacent C (when R2 = (IIb)) or bond that connects (IIb) with adjacent O (when R1+R2+C = (IIb)). Provided that when n is 1, then the bonds that link carbon atom with R1 and R2, and a and b, in (I) represent single bond, when n = 0, then the bonds that link carbon atom with R1 and R2, and a and b, in (I) represent aromatic bonds, and cyclohexyl ring, phenyl ring and groups R3-R5 exhibit 6-10C. Independent claims are also included for: (1) 2-(4-isopropylcyclohexyloxy)acetaldehyde; (2) 1-(2,2-diethoxyethoxy)-4-isopropylcyclohexane; (3) 2-(3,5,5-trimethylhexoxy)acetaldehyde; (4) a mixture comprising (a) (I), (b) 2->= 10 additional perfumes, which do not contain (I), (c) at least one solvent comprising trialkyl citrates, preferably triethyl citrate, trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate, triisobutyl citrate or tri-sec-butyl citrate, dialkyl phthalates, preferably dimethyl phthalate, diethyl phthalate or dibutyl phthalate, benzyl benzoate, isopropyl myristate or dioctyl adipate, and/or (d) washing and cleaning agents, hygiene or care products for body and hair care, cosmetics and household products, fine fragrances, perfume oils, air care products, preferably candles, air fresheners and agents for cleaning, treating and/or maintenance of surfaces and textile fibers; (5) providing skin, hair, surfaces or textile fibers with (i) a lily of the valley-odor note, optionally (iia) odor notes including floral-, fruity-, watery-, green- or aldehydic notes, and/or (iib) impressions including natural-, fresh-, nourishing-, gentle-, warm-, complex- and radiant impressions, comprising providing (I) or the above mixture, and applying (I), the mixture or perfumed product on skin, hair, fiber or textile surfaces; and (6) providing and/or enhancing (i), optionally (iia) and/or (iib), comprising mixing or contacting (I) or the above mixture with a product.
