Definitions

  • the invention relates to fragrance precursors.
  • the invention relates to the use of several classes of compounds which can act as fragrance precursors, e.g. in consumer, e.g. cosmetic products, such as deodorants and antiperspirants. These compounds are normally odourless or nearly so, but upon contacting the skin as for example, in skin care compositions or in personal care compositions, produce fragrances.
  • a principal strategy currently employed in imparting odours to consumer products is the admixing of the fragrance directly into the product. There are however, several drawbacks to this strategy.
  • the fragrance material can be too volatile, resulting in fragrance loss during manufacturing, storage, and use. Many fragrance materials are also unstable over time. This again results in loss during storage.
  • fragrances are microencapsulated or treated with cyclodextrins to form inclusion complexes to help decrease volatility and improve stability.
  • cyclodextrins can be too expensive.
  • the present invention now provides compounds (and their use), which show a low level of odour, or are even odourless, prior to application to the skin, but which release odorant molecules after application to the skin (that is, they provide a delayed release of the fragrance), in particular to the skin in the axilla.
  • the compounds under consideration are compounds of the formula
  • Rl is a radical derived from an odoriferous alcohol of the formula Rl OH, wherein
  • R 2 is one or more building blocks selected from an optionally substituted C ⁇ _30-alkyl or C2-30- alkenyl radical, a carbocyclic, aromatic or heterocyclic radical, whereby all these radicals may in addition contain one or more hetero atoms, such as O, N, S, P, and groups such as (OCH2CH2) n
  • R 3 is independently H, R 1 , R 2 , X ,
  • R 4 is R 1 or R 2 ,
  • X is H, an alkali metal ion, one equivalent of an earth alkali metal or of the Al, Zn or Fe ion, or an optionally mono-, di- or trisubstituted ammonium ion,
  • n 1 -20.
  • alcohols R ⁇ OH are primary or secondary alcohols- or phenols - such as:
  • Flavors & Fragrances * citronellol* geraniol* oct- l -en-3-ol
  • BASF * l-(2-tert-butyl-cyclohexyloxy)-2-butanol (Amber Core, Kao)* l-(4-isopropyl-cyclohexyl)-ethanol (Mugetanol, H&R)* etc.

  • glycine alanine arginine asparagine aspartic acid glutamic acid histidine isoleucine leucine lysine proline serine threonine tyrosine phenylalanine tryptophan valine gluconic acid glycyrrhizic acid, thiodiglycolic acid thiodiprop
  • R 2 extends from C l to C30 alkyl and alkenyl, and one or more unsaturations may be present, and the respective chains may be linear or branched.
  • the carbocycles encompass in particular, optionally substituted
  • cycloalkanes cycloalkenes polycycloalkanes polycycloalkenes
  • aromatic rings encompass in particular, optionally substituted
  • heterocycles encompass in particular, optionally substituted pyridine pyrrole pyrrolidine pyrimidine furane thiophene tetrah ydrofuran quinoline furanose pyranose.
  • the radicals R 3 may be the same or different.
  • the compounds I may preferably be used as sustained release odorants but also to mask or attenuate undesirable odours or to provide additional odours not initially present in consumer products, i.e. cosmetic products destined for application to human skin such as underarm deodorants or antiperspirants or other deodorants contacting the body, or in hand lotions, baby powders, baby lotions, ointments, foot products, facial cleansers, body wipes, facial make-up, colognes, after-shave lotions, shaving creams, etc.
  • the compounds I are virtually odourless under normal temperature and atmospheric conditions, i.e. about 10-50 degrees Celsius and about 20 to 100% relative humidity. However, when applied to the body, they undergo a transformation in which the fragrant alcohol is released.
  • the compounds I are not limited to any particular stereo- isomers, all possible stereoisomers, geometric isomers as well as well as racemates are thus included within the scope of formula I.
  • the compounds I upon cleavage, provide alcohols having organoleptic properties and therefore permit the development of methods useful in enhancing the odour of consumer products. These compounds may be used individually in an amount effective to enhance the characteristic odour of a material. More commonly, however, the compounds are mixed with other fragrance components in an amount sufficient to provide the desired odour characteristics.
  • the amount required to produce the desired, overall effect varies depending upon the particular compounds I chosen, the product in which it will be used, and the particular effect desired.
  • an odorant i.e. an odoriferous alcohol in an "organoleptically effective amount" is released when the deodorant is used.
  • This newly formed odorant serves to enhance the odour of the fragrance and in this way mask, e.g. the underarm odour, depending upon the selection and use levels of the compounds I.
  • the compounds I can accordingly be used in the manufacture of odorant compositions used in the preparation of cosmetic products, e.g. deodorants and antiperspirants, and as is evident from the above compilation, a broad range of known odorants or odorant mixtures can be used.
  • the known odorants or odorant mixtures set forth above can be used according to methods known to the perfumer, such as e.g. from W.A. Poucher, Perfumes, Cosmetics, Soaps, 2, 7th Edition, Chapman and Hall, London 1974.
  • the present invention relates to:
  • a fragrance precursor composition preferably a composition for application to human skin, containing an organoleptically effective amount of at least one compound of the formula I in a acceptable, preferably a cosmetically acceptable carrier.
  • a fragrance precursor containing product e.g. cosmetic product, e.g. a personal body deodorant or antiperspirant article, containing at least one compound I.
  • a method of suppressing human body malodour by means of compounds of the formula I which comprises the application, e.g. to human skin of a cosmetic product as defined above.
  • these compounds I may be obtained by reaction of the alcohol part, if necessary derivated, with the acid part, if necessary activated, of the molecule I.
  • This compound was prepared as above, but starting from 10- undecenyl bromo acetate.
  • citronellol was reacted with 3,6,9-trioxaundecanedioic acid (Hoechst) as above.

After an additional 2 hours stirring at room temperature, the reaction mixture was filtered and the white solid washed with 200 ml of MTBE. The filtrate was washed with 10% sodium bicarbonate solution, 0.1N hydrochloric acid and brine, dried and evaporated to dryness to give 35 g of yellow oil.

Abstract

L'invention concerne des précurseurs de parfums. En particulier, l'invention concerne l'utilisation de plusieurs classes de composés qui peuvent servir de précurseurs de parfums, par exemple, dans des produits de consommation tels que des produits cosmétiques, et plus précisément, des déodorants et des antitranspirants. Ces composés sont normalement sans, ou pratiquement, sans odeur, mais lors de leur contact avec la peau, comme par exemple dans les compositions de soins de beauté ou de soins personnels, ils dégagent un parfum en libérant un alcool odoriférant.
