Definitions

  • the present invention relates to a solid, particulate composition
  • a solid, particulate composition comprising at least one water-soluble carrier material and at least one fragrance
  • the carrier material being a water-containing salt (hydrate) whose water vapor partial pressure is equal to H 2 O at a certain temperature in the range from 30 to 100 ° C -Partial pressure of the saturated solution of this salt corresponds, so that the salt melts in its own crystal water at this temperature.
  • the composition is characterized by the fact that it has significantly improved water solubility compared to known polyethylene glycol-based compositions.
  • the invention further relates to methods for producing the solid composition, as well as a detergent or cleaning agent which contains the solid composition.
  • the present invention also relates to the use of such a detergent or cleaning agent for cleaning textiles or hard surfaces and corresponding methods for cleaning textiles or hard surfaces using such a detergent or cleaning agent.
  • a detergent or cleaning agent for cleaning textiles or hard surfaces
  • the consumer not only aims to wash, clean or care for the objects to be treated, but he also wants the treated objects, such as textiles, to be cleaned after treatment, for example the laundry smells pleasant. For this reason in particular, most commercially available detergents and cleaning agents contain fragrances.
  • Fragrances are often used in the form of fragrance particles either as an integral part of a detergent or cleaning agent, or dosed into the washing drum in separate form directly at the beginning of a wash cycle. In this way, the consumer can control the scent of the laundry to be washed through individual dosage.
  • the main component of such fragrance pastilles known in the art is typically a water-soluble or at least water-dispersible carrier polymer, such as polyethylene glycol (PEG), which serves as a vehicle for the integrated fragrances and which is more or less completely dissolved in the washing liquor during the waxing process dissolves in order to release the fragrances it contains and, if necessary, other components into the washing liquor.
  • PEG polyethylene glycol
  • a melt is produced from the carrier polymer, which contains the remaining ingredients or these are then added, and the resulting melt is then fed to a shaping process, during which it cools down solidifies and takes the desired shape. Fragrance particles from the prior art are mentioned, among other things, in the published publications DE 10 2012 218 690 A1 and DE 199 53 503 A1 described.
  • the known products have the disadvantage that the polymer materials used, in particular PEG, have a delayed solubility, which can lead to residues on the laundry or in the washing machine, especially with short wash cycles, low temperatures or other unfavorable conditions.
  • the object of the present invention was therefore to identify an alternative composition which shows a suitable processing range and at the same time has improved water solubility in the usual temperature ranges in which work is carried out.
  • the corresponding composition should also be characterized by an attractive appearance.
  • a formulation for melted bodies which comprises a carrier material, and one or more fragrances and additionally at least one water-soluble organic solvent, the carrier material being a water-containing salt (hydrate) whose water vapor partial pressure at a certain temperature is in the range from 30 to 100 ° C corresponds to the H 2 O partial pressure of the saturated solution of this salt at the same temperature, so that the salt dissolves in its own crystal water at this temperature, a process which can phenomenologically be described as melting, in which it is Thermodynamically, however, it is a solution process.
  • hydrate water-containing salt
  • the present invention is directed to the use of the melt bodies, as described herein, as textile care products, preferably scenting agents, for scenting textile fabrics.
  • the present invention is further directed to a detergent or cleaning agent comprising melts as described herein.
  • At least one refers to 1 or more, for example 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this information refers to the type of agent/compound and not the absolute number of molecules. “At least one fragrance” therefore means that at least one type of fragrance is recorded, but 2 or more different types of fragrance can also be included.
  • Water soluble as used herein means a solubility in water at 20°C of at least 1 g/L, preferably at least 10 g/L, more preferably at least 50 g/L.
  • the solid, particulate composition as described herein is prepared from a solution of the carrier material in the water/water of crystallization contained in the composition, the term “melt” also being used herein for such a solution in contrast to the established usage, to describe the state in which the carrier material dissolves in its own crystal water by splitting off water and thus forms a liquid.
  • the term “melt” as used herein therefore refers to the liquid state of the composition that arises when the temperature is exceeded at which the carrier material splits off water of crystallization and then dissolves in the water contained in the composition.
  • the corresponding dispersion which contains the (solid) substances described herein dispersed in the melt of the carrier material, is therefore also the subject of the invention.
  • the corresponding melt/melt dispersion from which it is available is always included. Since they do not differ in composition with the exception of the physical state, the terms are used synonymously herein.
  • molten body is used herein to describe the solid particles obtainable from the liquid composition upon cooling by solidification/forming.
  • the main component of the particulate solid composition as described herein is at least one water-soluble carrier material.
  • the at least one carrier material is characterized in that it is selected from water-containing salts whose water vapor partial pressure at a temperature in the range from 30 to 100 ° C corresponds to the H 2 O partial pressure of the saturated solution of this salt at the same temperature. This leads to the corresponding water-containing salt, also referred to herein as "hydrate", dissolving in its own crystal water when this temperature is reached or exceeded and thereby becoming a solid turns into a liquid state.
  • the carrier materials according to the invention preferably show this behavior at a temperature in the range from 40 to 90 ° C, particularly preferably between 50 and 85 ° C, even more preferably between 55 and 80 ° C.
  • the previously described water-soluble carrier materials from the group of water-containing salts include, in particular, the sodium acetate trihydrate (Na(CH 3 COO) ⁇ 3H 2 O), the Glauber's salt (Na 2 SO 4 ⁇ 10H 2 O), the trisodium phosphate dodecahydrate (Na 3 PO 4 ⁇ 12 H 2 O) and the strontium chloride hexahydrate (SrCl 2 ⁇ 6 H 2 O).
  • a particularly suitable hydrate is sodium acetate trihydrate (Na(CH 3 COO) ⁇ 3H 2 O), since it dissolves in its own crystal water in the particularly preferred temperature range of 55 to 80 ° C, specifically at around 58 ° C.
  • the sodium acetate trihydrate can be used directly as such, but it is also possible to use anhydrous sodium acetate in combination with free water, whereby the trihydrate then forms in situ .
  • the water is used in a substoichiometric or superstoichiometric amount based on the amount necessary to convert all of the sodium acetate into sodium acetate trihydrate, preferably in an amount of at least 60% by weight, preferably at least 70% by weight .-%, more preferably at least 80% by weight, most preferably 90% by weight, 100% by weight or more of the amount theoretically required to convert all of the sodium acetate into sodium acetate trihydrate (Na(CH 3 COO) ⁇ 3H 2 O).
  • the superstoichiometric use of water is particularly preferred.
  • composition containing 50% by weight of anhydrous sodium acetate and no hydrate thereof will contain at least 19.8% by weight of water (60% of the 33% by weight that would theoretically be necessary to contain all the sodium acetate to be converted into the trihydrate).
  • the at least one carrier material is used in an amount such that the resulting melt body, ie the fragrance pastille, is from 30 to 95% by weight. preferably contains from 40 to 90% by weight, for example 45 to 90% by weight, based on the total weight of the melt body, of the carrier material.
  • a fragrance is a chemical substance that stimulates the sense of smell.
  • the chemical substance should be at least partially dispersible in the air, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity will quickly subside. However, with a lower volatility, the odor impression is more lasting, i.e. it does not disappear as quickly.
  • the fragrance therefore has a melting point which is in the range from -100°C to 100°C, preferably from -80°C to 80°C, even more preferably from -20°C to 50°C, in particular from - 30°C to 20°C.
  • the fragrance has a boiling point which is in the range from 25°C to 400°C, preferably from 50°C to 380°C, more preferably from 75°C to 350°C, in particular from 100°C to 330°C.
  • the fragrance has a molecular weight of 40 to 700 g/mol, more preferably 60 to 400 g/mol.
  • fragrance The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Fragrances can also be used to mask unpleasant odors or to give a non-smelling substance a desired smell.
  • Individual fragrance compounds for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.
  • Fragrance compounds of the aldehyde type are, for example, Adoxal (2,6,10-trimethyl-9-undecenal), anisaldehyde (4-methoxybenzaldehyde), Cymal (3-(4-isopropyl-phenyl)-2-methylpropanal), ethyl vanillin, florhydral ( 3-(3-isopropylphenyl)butanal), Helional (3-(3,4-methylenedioxyphenyl)-2-methylpropanal), Heliotropin, Hydroxycitronellal, Lauraldehyde, Lyral (3- and 4-(4-Hydroxy-4-methylpentyl)- 3-cyclohexene-1-carboxaldehyde), methylnonylacetaldehyde, Lilial (3-(4-tert-butylphenyl)-2-methylpropanal), phenylacetaldehyde, undecylenaldehyde, vanillin, 2,
