Description

Die vorliegende Erfindung betrifft ferner ein Kit zur Herstellung einer Vorrichtung zum Freisetzen eines Wirkstoffes in die Umgebung.The present invention relates to a device ( 1 ) for releasing an active substance into the environment, comprising or consisting of the following components: a) a container ( 2 ), the at least one container opening ( 4 b) a liquid composition ( 5 ) consisting of or comprising b1) water, b2) at least one, two, three or four compounds of the general formula (I)

in which R ¹ , R ² , R ³ and R ⁴ independently of one another represent hydrogen, methyl, ethyl, propyl, butyl, pentyl or hexyl, b3) one or more active substances, b4) optionally one or more dyes and b5) optionally one or more several preservatives, and c) at least one diffusion bar ( 3 . 3 ' . 3 ' ) in contact with the liquid composition ( 5 ) and through the container opening ( 4 ) from the container ( 2 ). The present invention further relates to a kit for producing a device for releasing an active substance into the environment.

For the scenting and refreshment of rooms evaporation systems are often used in addition to spraying systems. These evaporation systems have the advantage over spraying systems of generating an almost constant fragrance over the entire running time, whereas spraying systems produce only an intense scent after each spray burst, which gradually decreases.

Evaporation systems typically consist of a container comprising a fragrance dissolved in a liquid and a diffusion stick contained in the container. The diffusion rods are designed so that they absorb the liquid and dissolved in the liquid perfume due to capillary forces and convey along the diffusion rod from the container. On the surface of the diffusion rods, the liquid together with perfume then evaporates and the fragrance is released into the environment. In order to improve the aesthetics of the evaporation systems, two-phase systems are increasingly being used, whereby the different phases can also be colored differently. The different phases are predominantly an upper phase consisting of a water immiscible oil and a lower aqueous phase.

In the WO 2004/032983 A1 For example, a composite wick is described for supplying two liquids having different properties to a surface, wherein the composite wick has a first portion intended to supply a first liquid to the surface of the wick and a second portion to supply a second liquid to the surface Surface of the wick is provided includes. The fluids used are an oil-based fluid and a water-based fluid.

In the EP 1 847 175 A1 There is described a two-phase evaporator apparatus having a container containing two immiscible liquids, and two different wicks, one of the wicks having an impermeable layer extending from its lower end to the closure lid of the container and containing the Contact of the wick with the upper liquid prevented.

In the EP 3 120 873 A1 [0009] A biphasic evaporator apparatus is described comprising a receptacle comprising a lower aqueous phase and an upper oily phase (silicone oil) and at least one hydrophobic wick of a first material and a second wick of a second material. The two different wicks evaporate the different phases more evenly.

In the US 2009/0101729 A1 a three-phase evaporator apparatus will be described. To achieve an aesthetically pleasing effect, the three phases are not miscible with each other. The specific weights of the layers are adjusted to be released to the atmosphere via a polar wick of rattan or a blend of a polar wick of rattan and a non-polar wick of glass fibers.

The two-phase evaporator devices described in the prior art have the disadvantage that an adjustment of the intensity, ie the evaporation rate, is not readily possible. When using the in the EP 1 847 175 A1 The composite wick described above can only adjust the evaporation rate during the manufacture of the wick by adjusting the diameter of the wick to the desired evaporation rate. A later adjustment of the evaporation rate is no longer possible. In the In the EP 1 847 175 A1 and EP 3 120 873 A1 two-phase evaporator devices described two different wicks are used, each type of wick is responsible for the evaporation of a phase. By adjusting the number of wicks, the evaporation rate can be adjusted, but the exact ratio between the first type of wick and the second type of wick must be taken into account. Otherwise, this leads to the fact that the individual phases are evaporated at different rates. Since the different wick types are difficult to distinguish or the end user is often unaware of the difference between both wicks, this regularly leads to the end customer being dissatisfied with the two-phase evaporator device since the phases are consumed at different rates after the end user wicks to adjust the evaporation rate to his needs.

It was therefore an object of the present invention to provide a device for releasing an active substance into the environment, in which the evaporation rate can be set by the end customer. If two liquid phases develop in the device, they should preferably be consumed as evenly as possible, so that the phase ratio remains approximately constant over the entire running time of the device.

• a) ein Behälter (2), der zumindest eine Behälteröffnung (4) aufweist,
• b) eine in dem Behälter befindliche flüssige Zusammensetzung (5) bestehend aus oder umfassend
  • b1) Wasser,
  • b2) mindestens eine, zwei, drei oder vier Verbindungen der allgemeinen Formel (I)

  • b3) einen oder mehrere Wirkstoffe,
  • b4) optional einen oder mehrere Farbstoffe und

This object is achieved according to the invention by a device ( 1 ) for releasing an active substance into the environment, comprising or consisting of the following components:

• a) a container ( 2 ), the at least one container opening ( 4 ) having,
• b) a liquid composition in the container ( 5 ) consisting of or comprising
  • b1) water,
  • b2) at least one, two, three or four compounds of the general formula (I)
    
    where R 1, R 2, R 3 and R 4, independently of one another, represent hydrogen, methyl, ethyl, propyl, butyl, pentyl or hexyl,
  • b3) one or more active substances,
  • b4) optionally one or more dyes and
  • b5) optionally one or more preservatives,
  and
• c) at least one diffusion rod ( 3 . 3 ' . 3 ' ) in contact with the liquid composition ( 5 ) and through the container opening ( 4 ) from the container ( 2 ).

It has surprisingly been found that in liquid compositions used according to the invention, the water, at least one compound of formula (I) and one or more active ingredients also contain two-phase systems can be formed, wherein the individual phases even with the use of only one diffusion bar or several diffusion rods of the same kind over the entire life of the device evenly.

This is particularly surprising because the compound of formula (I) is miscible with water in a wide range. However, the system has a miscibility gap, ie there are areas where the compound of formula (I) is not miscible with water. In the two-phase evaporator devices hitherto described in the prior art oils were used which are almost immiscible with water or almost insoluble in water. Often, silicone oils, such as decamethylcyclopentasiloxane, have been used which are almost insoluble in water. As has now been shown, you are so far erroneously assumed that for the production of two-phase systems always two substances must be used, which have no solubility in each other.

As a result of the partial mixing of water and the compound of the formula (I), the liquids are equal in viscosity and polarity, which surprisingly leads to the fact that the individual phases can be conveyed uniformly with only one type of diffusion rod and thus one uniform decrease of both phases over the entire life of the device takes place. This is not possible, for example, when using oils which by definition have a high viscosity, and water as phases, and it is therefore necessary to use two diffusion rods adapted in each case to the individual phases.

Preferred is a device according to the invention, wherein when R ^{1 is} hydrogen, R ^{2 is} methyl, ethyl, propyl, butyl, pentyl or hexyl and when R ^{2 is} hydrogen, R ^{1 is} methyl, ethyl, propyl, butyl, pentyl or hexyl.

Also preferred is a device according to the invention, wherein when R ^{3 is} hydrogen, R ^{4 is} methyl, ethyl, propyl, butyl, pentyl or hexyl and when R ^{4 is} hydrogen, R ^{3 is} methyl, ethyl, propyl, butyl, pentyl or hexyl.

A device according to the invention is particularly preferred, the compounds of the general formula (I) (2- (2-methoxy-1-methyl) ethoxy) -1-methylethyl acetate, (2- (2-methoxy-2-methyl) ethoxy) 1-methylethyl acetate, (2- (2-methoxy-2-methyl) ethoxy) -2-methylethyl acetate or (2- (2-methoxy-1-methyl) ethoxy) -2-methylethyl acetate. These compounds each have two chiral centers, so that each of the compounds is an RR, RS, SR and SS form possible. These are reproduced below:

Particularly preferred according to the invention is a device wherein the liquid composition as compounds of the general formula (I) is one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen or all the links shown above 1 to 16 includes.

Very particularly preferred according to the invention is a device wherein the liquid composition comprises as the compound of general formula (I) at least or only (2- (2-methoxy-1-methyl) ethoxy) -1-methylethyl acetate.

According to the invention, preference is given to a device in which a weight ratio between water and the sum of all compounds of the general formula (I) is from 7: 3 to 3: 7, preferably from 6: 4 to 4: 6, more preferably from 11: 9 to 9 : 11 is present, more preferably 1: 1. Since the active ingredients, in particular fragrances, are usually in the phase formed by the compounds of general formula (I), it is therefore surprising that 1: 1 mixtures have the best properties. In fact, one would rather use an excess of water to compensate for the volume of the active ingredients, so that as a result and taking into account the volume of the active ingredients two equal phases are formed. In addition, in the above-mentioned mixing ratios, two phases are formed.

According to the invention, a device is preferred in which the liquid composition contains more than 2% by weight of water, preferably more than 5% by weight of water, particularly preferably more than 10% by weight of water.

• 35 bis 51 Gew.-%, vorzugsweise 43 bis 47 Gew.-% Wasser,
• 35 bis 48 Gew.-%, vorzugsweise 43 bis 47 Gew.-% mindestens eine, zwei, drei oder vier Verbindungen der allgemeinen Formel (I),
• 0,5 bis 25 Gew.-%, vorzugsweise 6 bis 12 Gew.-% Wirkstoffe (vorzugsweise Duftstoffe) und
• 0 bis 5 Gew.-%, vorzugsweise 0 bis 2 Gew.-% weiterer Bestandteile

umfasst oder daraus besteht.Particularly preferred according to the invention is a device wherein the liquid composition

• From 35 to 51% by weight, preferably from 43 to 47% by weight, of water,
• From 35 to 48% by weight, preferably from 43 to 47% by weight, of at least one, two, three or four compounds of the general formula (I)
• 0.5 to 25 wt .-%, preferably 6 to 12 wt .-% of active ingredients (preferably perfumes) and
• 0 to 5 wt .-%, preferably 0 to 2 wt .-% of further ingredients

includes or consists of.

According to the invention, a device is preferred, wherein the liquid composition forms exactly two phases. Ie. that in addition to the aqueous phase and the phase which is formed predominantly from the compounds of general formula (I), no further phase is present, in particular no silicone phase, such as decamethylcyclopentasiloxane.

Our own investigations have shown that despite the presence of two phases in devices according to the invention, the vaporization of both phases via the diffusion rods proceeds approximately uniformly, so that the phases decrease uniformly over the entire lifetime of the device. If, nevertheless, one of the two phases should remain at the end of the life of the device according to the invention - for example, because the preferred mass ratios according to the invention are not met and a large excess of water is used - the remaining phase is then vaporized solely by the diffusion rods. Namely, since the compound of the general formula (I) and water are miscible with each other, the remaining phase always contains both components, so that the excellent vaporization properties are maintained even when there is only one phase.

According to the invention, a device is preferred in which the liquid composition does not contain decamethylcyclopentasiloxane, preferably does not contain (at 25 ° C.) liquid organosilicon compounds.

According to the invention, a device is preferred in which the mass fraction of active substances or active substances in the entire liquid composition is 0.5 to 25%, preferably from 2 to 20%, particularly preferably from 5 to 15%.

Our own investigations have shown that the above-stated mass fractions of active ingredients lead to particularly good properties. At a mass fraction of active ingredient of less than 0.5% is often not sufficient evaporation of the active ingredient achieved, so this does not seem sufficient or is perceived. If the proportion by mass of active ingredient is too high, usually too large an amount of the active ingredient is vaporized. In addition, the active ingredient has a strong influence on the viscosity and the polarity of the liquid composition at excessive mass fractions.

According to the invention, a device is preferred, wherein the active substance or the active ingredients are fragrances, antimicrobial active substances and / or insect repellents. However, it is not excluded that, for example, some fragrances also simultaneously have an effect against insects, as is the case with citronellol and geraniol, for example. According to the invention, the active ingredient is a perfume.

For the purposes of this text fragrance means a substance or mixture of substances which is perceived olfactorily. The compounds of the general formula (I) are not classified according to the invention as fragrances.

In a container ( 2 ), which has a container opening ( 4 ), there is a liquid composition ( 5 ), the two phases ( 6 . 7 ) trains. The liquid composition ( 5 ) comprises water, at least one, two, three or four compounds of general formula (I) and a fragrance mixture as active ingredient. Of the two phases ( 6 , 7) the lower phase ( 7 ) formed predominantly of water, while the upper phase ( 6 ) is formed predominantly of compounds of general formula (I) and the fragrance mixture. However, part of the compounds of general formula (I) also dissolve in the lower phase ( 7 ). In the container are three diffusion rods ( 3 . 3 ' . 3 ' ) which are in contact with the liquid composition ( 5 ) and through the container opening ( 4 ) from the container ( 2 ). With the diffusion sticks ( 3 . 3 ' . 3 ' ) are fiber diffusion sticks formed of polyethylene terephthalate. The individual phases ( 6 , 7) can be colored differently, for example, in which the lower color is not colored and the upper phase is colored with a dye that does not dissolve in the lower phase.

Example:

45 g of a mixture of the compounds (1) to (16) are mixed with 10 g of fragrance and transferred to a cylindrical glass bottle. Subsequently, 45 g of water are added. The mixture is stirred and then the mixture is allowed to stand until two phases form. The volume of the individual phases is approximately identical. Through the opening of the glass bottle, five fiber diffusion sticks of polyethylene terephthalate are introduced, so that the liquid composition can be transported via the fiber diffusion rods from the glass bottle and vaporized on the surface of the diffusion rods.

Until the complete evaporation of the liquid composition, the height of the respective phases and the weight of the glass bottle and its contents are determined. It has been shown that the phases decrease evenly and there is a uniform weight loss over the entire duration. The fragrance intensity is very good over the entire duration.
