  • European Patent EP 1 976 855 B1 describes bicyclic oxazolidines which are used as perfume precursors and release a fragrance by slow hydrolysis, thereby generating a long-lasting fragrance.
  • European patent EP 2 087 089 B1 describes the use of perfume microcapsules as a depot system, wherein the capsules break open at a defined time and provide an intense fragrance in the short term.
  • this technology is associated with great technical effort and high costs and the capsule wall material has no direct function after breaking the capsules.
  • the object of the present invention was therefore to provide a perfume composition with an arbitrary but specific scent profile which has a higher scent intensity than conventional perfume compositions, without necessarily relying on complex technologies such as perfume precursors or depot systems.
  • a perfume composition comprising at least one odor modulator compound (GMV), wherein each individual odor modulator compound, based on the total perfume composition, is contained in an amount of 2 wt .-% to 0.000001 wt .-%, and
  • the at least one heteroatom is selected from N, O, S, Si, Se, F, Cl, Br or I, and
  • the fragrance intensity of a perfume composition containing at least one odor modulator compound according to the invention is increased.
  • an odor modulator compound of the invention in a perfume composition, therefore, the amount of perfume composition in a consumer product such as Textile treatment, cleaning, cosmetics or adhesive can be significantly reduced without reducing the intensity of the fragrance or substantially alter the fragrance profile of the perfume composition.
  • perfume compositions of the present invention because of the smaller amount necessary to achieve the same scent intensity, can be more stably incorporated into common consumer products than conventional perfume compositions.
  • Numeric ranges specified in the format "from x to y" include the above values. If multiple preferred numeric ranges are specified in this format, it is understood that all ranges resulting from the combination of the various endpoints, are also included.

  • At least one odor modulator compound therefore means, for example, one or more different odor modulator compounds, ie one or more different types of odor modulator compounds. Together with quantities, the quantities given refer to the total amount of the corresponding designated type of ingredient, unless otherwise specified.
  • At least one odor modulator compound such as the odor threshold value, the ClogP value, quantities or ratios, apply to each individual odor modulator compound.

  • a fragrance is a compound which has a characteristic odor and contributes to the achievement of a specific fragrance profile of a perfume composition. Fragrances also include those compounds which alter the fragrance profile of a perfume composition such that the fragrance acquires a certain depth, which the person skilled in the art usually knows as the complexity of a fragrance. However, a fragrance within the meaning of the present invention has no direct influence on the fragrance intensity of the perfume composition, as long as the perfume composition is used at a constant concentration.
  • the fragrance profile of a perfume composition is the specific fragrance a consumer perceives due to the fragrance it contains.
  • a fragrance for example, flowery, spicy, sweet, sour, tart, fresh, woody, fruity, leathery, oriental, animal, chypre, fougere, citrus, edible, green, musky, ozone, aldehydic, smell agriculturally, aromatic or marine, which can be achieved by the special selection of the individual fragrances in the perfume composition complex fragrance profiles and a floral fragrance can smell, for example, rose, violet or lavender.
  • a scent profile is therefore the characteristic scent of each perfume composition, which results from the fragrances used.
  • An odor modulator compound (GMV) in the context of the present invention is a compound which may have a characteristic odor but at the concentration used, under the test conditions given below, not or not significantly to a change in the fragrance profile of the perfume composition containing at least one odor modulator - Connection, contributes.
  • An insignificant change in the fragrance profile of the perfume composition means that although the fragrance profile may differ slightly from the original fragrance profile of the perfume composition, it is still recognized by the skilled person as the original fragrance profile.
  • an odor modulator compound according to the present invention despite its low use concentration, has a significant influence on the consumer perceived fragrance intensity of the perfume composition, so that, for example, a lower amount of the perfume composition can be used to achieve the same fragrance intensity as in a conventional perfume composition without odor modulator compound.
  • An odor modulator compound therefore, unlike a fragrance contained in a perfume composition, does not define the fragrance profile, but rather enhances the fragrance intensity of the fragrance profile of the perfume composition as defined by the fragrances.
  • the at least one odor modulator compound does not substantially change the fragrance profile of the perfume composition, in principle any desired fragrance profile can be realized without the disturbing side notes being perceived.
  • An odor modulator compound increases the fragrance intensity of the perfume composition, which is described by the efficiency factor (E).

  • the low ratio of the at least one odor modulator compound compared to the fragrances contained in the perfume composition and the small amounts of the individual odor modulator ensures that the fragrance profile of the perfume composition changed at most insignificant, so that the expert further recognizes the fragrance profile of the original fragrance. Moreover, it is advantageous from an ecological and economic point of view to use only small amounts of the odor modulator compound.
  • the at least one odor modulator compound contains one to four heteroatoms and more preferably one to three heteroatoms independently selected from the group consisting of N, O, S, Si, Se, F, Cl, Br or I.
