Definitions

  • the invention relates to transparent liquids, in particular transparent textile treatment compositions containing at least one fragrance and microcapsules, wherein at least one odor modulator compound is contained. Furthermore, the invention relates to a method for providing transparent liquids, in particular transparent textile treatment agents such as liquid detergents or liquid fabric softeners.
  • the consumer associates with a lasting fragrance experience a long-lasting freshness and long-lasting cleanliness. For that reason, the consumer desires perfume compositions that impart a long-lasting fragrance to a substrate.
  • perfume compositions that impart a long-lasting fragrance to a substrate.
  • different methods for prolonging the scent result or methods for retarding the fragrance release are known from the prior art.
  • 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.
  • the 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 a relatively intense fragrance in the short term.
  • encapsulated fragrances has been proven for the scenting of substrates, especially of textile surfaces.
  • the encapsulated fragrances deposit on the surface, especially on and between the fibers of the textile surface, and may release the fragrance by diffusion of the fragrance from the capsule or by mechanically induced rupture of the capsule.
  • composition of the invention should also be able to be provided with any, but specific fragrance profile, which has a long-lasting high intensity of fragrance.
  • transparent, liquid perfume compositions as a microcapsule concentrate for example in the context of providing transparent liquid detergent or softener concentrates, should also be made possible.
  • a first object of the invention for solving this problem is a liquid, transparent composition, in particular as a textile treatment agent containing
  • Odor modulator compound wherein each individual odor modulator compound i) is contained in an amount of 2 wt .-% to 0.000001 wt .-% based on the totality of all the fragrances contained in the composition, and
  • ii) contains at least one heteroatom, wherein the at least one heteroatom
  • iii) has a molecular weight less than 250 g mol
  • Odor modulator compound (P) have rated as intensive, the sum of PGMV and P is at least 34.
  • the fragrance intensity of a liquid composition according to the invention containing microcapsules with at least one odor modulator compound and at least one fragrance is increased not only initially, but in particular also sustainably over a conventional perfume oil and conventional perfume microcapsules. It was particularly surprising that the effect achieved by at least one non-encapsulated odor modulator compound, by the use of at least one microencapsulated odor modulator compound is significantly enhanced again. In this case, effects were achieved, the sum of the individual effects that are achieved by the microencapsulation of at least one fragrance and the addition of at least one odor modulator compound to a perfume oil, usually even exceed, that is act synergistically.
  • a perfume composition of the invention can be stably incorporated into a conventional, especially liquid, consumer product or a highly concentrated consumer product.
  • suspensions of optical effect solids e.g. Pearlescent pigments, speckles or color pigments, a particularly good optical effect when the transparent, liquid composition according to the invention serves as a continuous phase of the suspension of these optical effect solids.
  • a fabric e.g., a composition
  • a fabric is solid according to the definition of the invention when in the solid state at 25 ° C and 1013 mbar.
  • a substance e.g., a composition
  • a substance is liquid as defined by the invention when in the liquid state at 25 ° C and 1013 mbar.
  • a chemical compound is an organic compound when the molecule of the chemical compound contains at least one covalent bond between carbon and hydrogen.
  • a chemical compound is, inversely to the definition of the organic compound, an inorganic compound when the molecule of the chemical compound does not contain a covalent bond between carbon and hydrogen.
  • the transparency of the liquid composition according to the invention can be determined by various methods.
  • the nephelometric turbidity unit (NTU) is often used as a measure of transparency. It is a unit used in water treatment for turbidity measurements in liquids. She is the unit a turbidity of a liquid measured with a calibrated nephelometer. High NTU values are measured for turbid liquids, while low values are determined for clear, transparent liquids.
  • liquids which are detectable to the naked eye in the sense of the invention have turbidity which is perceived as unaesthetic for a transparent composition.
  • the transparency of the compositions according to the invention was determined by a transmission measurement at 500 nm and 20 ° C.
  • the sample is measured in a light guide photometer (Metrohm 662 with turbidity sensor) with a light guide measuring cell with unscrewed mirror at a light path of 2 x 10 mm and a tungsten lamp (3.9 watts) as Lichttle.
  • an agent has a transmission of 55% at 500 nm, it is considered transparent in the sense of the invention. It is preferred if the agent according to the invention has a transmission of 60%, more preferably of 70%, most preferably of 80%.
  • microcapsules include any type of capsule known to those skilled in the art, but in particular core-shell capsules and matrix capsules.
  • Matrix capsules are porous shaped bodies that have a structure similar to a sponge.
  • Core-shell capsules are shaped bodies having a core and a shell.
  • Suitable microcapsules are those capsules which have an average diameter Xso, 3 (volume average) of 0.1 to 200 ⁇ , preferably from 1 to 100 ⁇ , more preferably 5 to 80 ⁇ , more preferably from 10 to 50 ⁇ and in particular from 15 to 40 have ⁇ .
  • the mean particle size diameter X 50.3 is determined by sieving or by means of a particle size analyzer Camsizer from Retsch.
  • microcapsule and “capsule” are used interchangeably for the purposes of the present invention.
  • At least one refers to 1 or more, for example, 2, 3, 4, 5, 6, 7, 8, 9 or more
  • this reference does not refer to absolute quantity of molecules but on the nature of the component.
  • 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.
  • a composition comprises at least one perfume which contributes substantially to the achievement of a specific odor profile.
  • a fragrance may be present in the form of a fragrance precursor compound or as a free fragrance.
  • a perfume oil is a combination of different fragrances and optionally solvents which produce a specific fragrance profile.
  • a perfume oil may also contain odor modulator compounds.
  • a perfume oil does not comprise any microencapsulated fragrances or microencapsulated odor modulator compounds.
  • fragrance and perfume are used synonymously in the context of the present invention.
  • a fragrance is a compound that has a characteristic odor and contributes to the achievement of a specific fragrance profile of a perfume composition or perfume oil. 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.
