Description

Solid perfumed composition

The present invention relates to a solid, particulate composition comprising at least one water-soluble carrier material, at least one rheology modifier and at least one perfume, wherein the carrier material is a hydrous salt (hydrate) whose water vapor partial pressure at a certain temperature in the range of 30 to 100 ° C. corresponds to the h O partial pressure of the saturated solution of this salt, so that the salt melts at this temperature in its own water of crystallization. Furthermore, the invention relates to processes for the preparation of the solid composition, as well as a washing or cleaning agent containing the solid composition. Moreover, the present invention also relates to the use of such a washing or cleaning agent for cleaning textiles or hard surfaces and corresponding methods for cleaning textiles or hard surfaces using such a washing or cleaning agent.

In the use of detergents and cleaners, the consumer not only aims to wash, cleanse or care for the objects to be treated, but also desires that the treated objects, e.g. Textiles, after the treatment, for example after the wash, smell pleasant. For this reason in particular, most commercially available detergents and cleaners contain fragrances.

Often fragrances are used in the form of perfume particles either as an integral part of a washing or cleaning agent, or dosed directly into the washing drum at the beginning of a wash cycle in a separate form. In this way, the consumer can control the fragrance of the laundry to be washed by individual dosage.

The main constituent 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 becomes more or less complete during the waxing process in the wash liquor dissolves, so as to release the fragrances contained and optionally other components in the wash liquor. For the preparation of the known fragrance pastilles, a melt is produced from the carrier polymer, which contains the other ingredients or these are then added, and the resulting melt is then fed to a shaping process, in the course of which it cools, it solidifies and assumes the desired shape.

The known products have the disadvantage that the polymer materials used, in particular PEG, have a delayed solubility, which is especially true for short Washing, low temperature or other unfavorable conditions may lead to residues on the laundry or in the washing machine.

However, it has now been found that an alternative composition which exhibits a suitable processing range and at the same time has improved water solubility in the usual temperature ranges in which work is carried out can be provided by using a water-containing salt in a formulation for fusible material as carrier material. Hydrate) is used, the partial pressure of water vapor at a certain temperature in the range of 30 to 100 ° C corresponds to the hhO partial pressure of the saturated solution of this salt at the same temperature, so that the salt dissolves at this temperature in its own water of crystallization, a process , which can be called phenomenologically melting, but which is thermodynamically a solution process. Particularly advantageous is the use of sodium acetate trihydrate.

The processing of these specific carrier materials is preferably carried out by means of a process in the course of which the salts are prepared as melts and are subsequently dropped, for example by means of a nozzle onto a cooling belt, on which they solidify and assume a final geometric shape. In processing, for example, dripping, the o.g. Melting into solidified particles has resulted in technical difficulties with respect to the reliable production of uniform particles of defined geometry and sufficient breaking strength for manufacture, packaging and transport. This resulted in difficulties in the design of the production plant and in terms of achieving a uniform product aesthetics.

It has been found that these disadvantages can be avoided regardless of the duration of the solidification process by adhering to specific rheological properties of the melt.

In yet another aspect, the present invention is directed to the use of the solid composition as described herein as a fabric care agent, preferably a fragrance, for scenting fabrics.

In yet another aspect, the present invention is further directed to a laundry or cleaning composition comprising a solid composition as described herein.

These and other aspects, features, and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Any feature of one aspect of the invention may be employed in any other aspect of the invention. In particular, it is intended that all preferred embodiments described herein be transferable to and combinable with all aspects of the invention. This applies in particular to the first to eighth aspects of the invention as described above. Further, it is to be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular that the invention is not limited to these examples.

All percentages are by weight unless otherwise specified. 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, also be recorded. "At least one" as used herein refers to 1 or more, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9 or more, more particularly, this indication refers to the type of agent / compound and not the absolute number of molecules. "At least one perfume, therefore, means that at least one type of perfume is detected, but may also contain 2 or more different types of perfume.

"About" or "approximately" as used herein in connection with a numerical value means the numerical value ± 10%, preferably ± 5%. A temperature of about 50 ° C thus means 45-55 ° C, preferably 47.5-52.5 ° C.

"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, wherein for such a solution the term "melt" is also used herein, in contrast to the established use, The term "melt", as used herein, thus refers to the liquid state of the composition which results when the temperature is exceeded in which the carrier material splits off water of crystallization and then dissolves in the water contained in the composition. The corresponding dispersion containing the herein described (solid) substances dispersed in the melt of the carrier material is thus also the subject of the invention. Thus, when reference is made below to the solid, particulate composition, the corresponding melt / melt dispersion from which it is obtainable is always included. Since these do not differ in composition except for the state of matter, the terms are used interchangeably herein.

Herein, the term "fusible body" is used to describe the solid particles obtainable from the liquid composition upon cooling by solidification / remelting.

The major component of the solid particulate composition as described herein is at least one water-soluble carrier material. The at least one support material is characterized in that it is selected from hydrous salts whose water vapor partial pressure at a temperature in the range of 30 to 100 ° C corresponds to the H20 partial pressure of the saturated solution of this salt at the same temperature. This causes the corresponding hydrous salt, also referred to herein as a "hydrate" dissolves when reaching or exceeding this temperature in its own water of crystallization and thereby of a solid changes into a liquid state of matter. Preferably, the support materials of the invention exhibit this behavior at a temperature in the range of 40 to 90 ° C, more preferably between 50 and 85 ° C, even more preferably between 55 and 80 ° C.

Among the above-described water-soluble carrier materials from the group of aqueous salts include in particular the sodium acetate trihydrate (Na (CH3COO) ^■ 3H2O), Glauber's salt (Na2S04 ^■ I OH2O), trisodium phosphate dodecahydrate (NasPC ^■ 12 H2O) and the strontium chloride hexahydrate ( SrCl ₂ ^■ 6 H2O).

A particularly suitable hydrate is sodium acetate trihydrate (Na (CH3COO) 3H2O ^■), as it is, specifically, solves in the most preferred temperature range of 55 to 80 ° C at about 58 ° C in their own crystal water. The sodium acetate trihydrate can be used directly as such, but it is alternatively possible to use anhydrous sodium acetate in combination with free water, the trihydrate then forming in situ. In such embodiments, the amount of water used is in less than or more than stoichiometric amount, based on the amount necessary to convert all the sodium acetate to sodium acetate trihydrate, preferably in an amount of at least 60% by weight, preferably at least 70% by weight %, more preferably at least 80%, most preferably 90%, 100% or more by weight of the amount theoretically required to convert all the sodium acetate to sodium acetate trihydrate (Na (CH 3 COO ) ^■ 3H2O). Particularly preferred is the superstoichiometric use of water. With respect to the compositions according to the invention, this means that when (anhydrous) sodium acetate is used alone or in combination with a hydrate thereof, preferably the trihydrate, water is also used, the amount of water being at least equal to the stoichiometrically necessary amount, to ensure that at least 60% by weight of the total amount of sodium acetate and its hydrates, preferably at least 70% by weight, more preferably at least 80% by weight, even more preferably at least 90% by weight, most preferably at least 100 wt .-%, in the form of sodium acetate trihydrate. As already described above, it is particularly preferred that the amount of water exceeds the amount that would theoretically be necessary to convert all of the sodium acetate to the corresponding trihydrate. This means, for example, that a composition containing 50% by weight of anhydrous sodium acetate and no hydrate thereof, at least 19.8% by weight of water (60% of 33% by weight, which would theoretically be necessary to remove all of the sodium acetate into the trihydrate).

All of the embodiments described below can be explicitly combined with both of the aforementioned alternatives.

In various embodiments, the at least one carrier material is used in an amount such that the resulting enamel body, ie the perfume pastilles, is from 30 to 95% by weight, preferably from 40 to 90 wt .-%, for example 45 to 90 wt .-%, based on the total weight of the fusible body, of the carrier material.

Another component of the particulate solid composition as described herein is at least one perfume. A fragrance is an odor-causing chemical substance. In order to stimulate the sense of smell, the chemical substance should be at least partially redistributable in the air, i. the perfume should be at least slightly volatile at 25 ° C. If the fragrance is now very volatile, the odor intensity then quickly decreases again. However, with lower volatility the odor impression is more sustainable, i. he does not disappear so fast. In one embodiment, therefore, the perfume has a melting point in the range of -100 ° C to 100 ° C, preferably from -80 ° C to 80 ° C, more preferably from -20 ° C to 50 ° C, especially of 30 ° C to 20 ° C. In a further embodiment, the perfume has a boiling point ranging from 25 ° C to 400 ° C, preferably from 50 ° C to 380 ° C, more preferably from 75 ° C to 350 ° C, especially from 100 ° C to 330 ° C is located.

Overall, a chemical substance should not exceed a certain molecular weight to act as a fragrance, since too high molecular weight, the required volatility can no longer be ensured. In one embodiment, the fragrance has a molecular weight of 40 to 700 g / mol, more preferably 60 to 400 g / mol.

The smell of a fragrance is perceived by most people as pleasant and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Thus, fragrances can also be used to superimpose unpleasant odors or even to provide a non-smelling substance with a desired odor.

The compositions contain as an essential ingredient a rheology modifier. Suitable rheology modifiers are inorganic and organic substances with corresponding properties influencing the rheology of the molten composition. These substances may be solid (at 20 ° C and 1 bar) or liquid ingredients, with the use of solid rheology modifiers is preferred.

The group of inorganic rheology modifiers includes, for example, the particularly preferred pyrogenic silica due to its advantageous technical effect.

This is preferably in an amount of 0, 1 to 20 wt .-%, preferably 0.5 to 3 wt .-%, more preferably 1 to 2.5 wt .-%, more preferably 1.2 to 2.0 wt. -% in the composition.

The silicas used are preferably highly disperse silicas, for example those with BET surface areas of more than 50 m ² / g, preferably more than 100 m ² / g, more preferably 150 to 250 m ² / g, in particular 175 to 225 m ² / g ,

Suitable silicas are commercially available from Evonik under the tradenames Aerosil® and Sipernat®. Particularly preferred is Aerosil® 200.

In the case of the organic rheology modifiers, the use of cellulose, in particular microfibrillated cellulose (MFC, nanocellulose), is preferred. As cellulose in particular MFCs are suitable, as for example as Exilva (Borregaard) or Avicel® (FMC) commercially available are. In addition or as an alternative to the abovementioned substances, it is possible for further solids or fillers to be present which differ from the abovementioned substances.

Microfibrillated cellulose (MFC) is preferably used in amounts of 0, 1 to 5 wt .-%, particularly preferably 0.1 to 3 wt .-%, more preferably 0.3 to 2 wt .-%, each based on the total weight of Composition, used.

In order to improve the aesthetic impression of the composition, it can be dyed with suitable dyes. Preferred dyes, the selection of which presents no difficulty to the skilled person, should have a high storage stability and insensitivity to the other ingredients of detergents or cleaning agents and to light and no pronounced substantivity to textile fibers so as not to stain them. Such dyes are known in the art and are typically used in concentrations of 0.001 to 0.5 wt%, preferably 0.01 to 0.3 wt%. Eventually, as described above, the composition may also contain free water. The term "free water" as used herein refers to water which is not bound as water of crystallization in any of the salts contained in the composition.

A composition as described herein may for example be used in the wash cycle of a laundry cleaning process and thus already transport the perfume directly to the laundry at the beginning of the washing process. Furthermore, the composition according to the invention is simpler and easier to handle than liquid compositions, since no drops remain on the edge of the bottle, which lead to edges on the substrate during subsequent storage of the bottle or to unsightly deposits in the region of the closure. The same applies in the event that some of the composition is accidentally spilled during dosing. The spilled amount can also be removed easier and cleaner. A process for the treatment of textiles, in the course of which a composition according to the invention is metered into the wash liquor of a textile washing machine, is a further subject of this application.

The composition may optionally contain other conventional ingredients, for example those which improve the performance and / or aesthetic properties.

Examples

example 1

The following table contains an example of a formulation according to the invention (all data in% by weight)

Table 1: Compositions

To prepare the sodium acetate trihydrate was heated to a temperature of 70 ° C and largely dissolved with stirring in his split-off water of crystallization. Subsequently, the other ingredients were incorporated. Using anhydrous acetate, the solution was prepared by stirring it with the formulation water and the microfibrillar cellulose containing 98% water at 70 ° C. Droppers were prepared by dropping the liquid mixture ("melt") to a cooled to room temperature (23 ° C) cooling plate.

The yield strength of the cellulose-containing formulation given above was measured as indicated in the description. It was 20 Pa. The fragrance pastilles according to the invention thus produced dripped to form uniform hemispherical pellets without falling apart.

The measurement of viscosities or a yield point was carried out using a rotational rheometer (AR G2 from TA Instruments or a "Kinexus" from Malvern).

A plate-plate measuring system with 40 mm diameter and 1, 1 mm plate spacing was used. The yield stress was determined in a step-flow procedure in which the shear stress was increased quasi-statically, ie, with the respective waiting for the equilibrium deformation or stationary flow from the smallest possible value to a value above the yield point. In a log logarithmic graph, the strain was plotted against the shear stress. In the presence of yield point, the curves thus obtained have one characteristic kink on. Below the bend, an exclusively elastic deformation takes place. The slope of the curve in the double logarithmic representation is ideally one. Above the bend, the slope of the curve increases sharply and there is steady flow. The shear stress value of the bend corresponds to the yield stress. If the kink is not quite sharp, the point of intersection of the tangents of the two curve sections can be used to determine the yield point.

For liquids that have no yield point, the graph described above is usually right-curved.
