Description

The invention relates to a water-soluble excipient for the production of fragrances to be enriched washing or rinsing in the machine drum of automatic washing machines.

From the DE 3911363 B4 It is known to use fragrances in the form of perfume tablets or capsules to make such washing or rinsing eyes. For this purpose, such a perfume tablet or capsule during a wash or rinse cycle, in this case exclusively a last wash or a final rinse phase exposed to a washing or rinsing purposes flushed amount of water. In this way, by dissolving the fragrance tablet or capsule in the flushed amount of water perfumes in sufficient quantities of washing or rinsing liquor are supplied. By exclusively adding the fragrances in the last wash cycle or in the final rinse phase, it should be ensured that added fragrances are not washed out again during the entire washing process.

The invention has the object of demonstrating a possibility with which the consistency of the active ingredient carrier can be influenced.

This object is achieved by the invention with the features of the main claim.

According to the invention it is possible, for example, to add a gelling agent to a liquid perfume concentrate or a fragrance solution in order to obtain a gelatinous gelling mass from a liquid initial state win, which disperses as portioned water-soluble drug carrier in a flushed for washing or rinsing purposes amount of water or there completely dissolves. Textiles, especially garments, in the machine drum of a fully automatic washing machine can be so evenly provided with fragrances.

Thus, for example, the active ingredient carrier can already be added to the machine drum at the beginning of the entire washing process, so that the fragrances can be released in a continuous manner into the washed-in amounts of washing water or flushing water and fixed to the textiles. Washing out of once set on the textiles fragrances takes place if at all minimally and is compensated by the continuous supply of fragrances.

Depending on the type and concentration of the gelling agent, for example in a liquid perfume concentrate, according to the invention the character, in particular the consistency, of the obtained gelatinous gelling mass can be influenced.

For example, the mixing ratio of the gelling agent to a liquid fragrance concentrate can be between 1:25 and 1: 100 in order to be able to adjust the character of the gelling compound, for example, from a slippery gel to a rubbery body. Also, by selecting a suitable gelling agent and its mixing ratio with a liquid perfume concentrate or a fragrance solution, the jelly strength of the gelling mass obtained can be influenced. For example, the jelly strength of the active substance carrier produced according to the invention can be between 50 and 500 Bloom.

In particular, when the active ingredient carrier according to the invention is to be formed into a rubber-soft body, the invention for its production offers the possibility of being able to use proven methods, in particular from confectionery production. For example, a starch bed prepared from starch powder can be used to produce impressions in the starch bed by means of a stamp. The impressions can then form molds in which the present invention with a gelling agent still liquid perfume concentrate can be poured to solidify there to drug carriers according to the invention, which may be formed in three dimensions and have a rubbery consistency. From the invention, therefore, there is the advantage that drug carriers can be molded by casting into a simple manner to arbitrarily shaped three-dimensional objects, without the aid of pressing pressures, such as those necessary for the preparation of tableted drug carriers from the above-mentioned prior art.

The invention further provides the advantage that the gelatinous gelation mass, to ensure its solubility in water, does not contain disintegrants, e.g. Sodium bicarbonate, must be added. For tableted drug carriers of the prior art disintegrants are needed to ensure their solubility. According to the invention eliminates the need for disintegrants due to the natural properties of gelatinous masses.

Furthermore, drug carriers prepared according to the invention tend to be less susceptible to crumbling due to their gelatinous composition.

As already mentioned above, the consistency of the active ingredient carrier can be achieved by adding suitable gelling agents in the appropriate ratio, for example in a fragrance solution, be influenced so that the gelatinous gelling mass assumes the character of a slippery gel. Such a gelling compound can be easily filled as a drug carrier, for example, in tubes or dispensers. In particular, the consumer is thereby given the opportunity to remove the active substance carrier in a simple manner from such packaging or containers in portions, in order to be able to expose a desired amount of the active ingredient carrier to a quantity of water scavenged for washing or rinsing purposes.

Due to the binding behavior of gelling agents, it is furthermore conceivable that the gelling mass obtained is dispersed, for example, in a quantity of flushed-in water in such a way that microscopically small perfume flocs are formed, which are e.g. on treated textiles, in particular garments. It can be assumed that fragrances dispersed in such a manner are more durable on textiles than dissolved fragrances from the above-mentioned prior art.

Furthermore, gelling agents may have environmentally friendly properties and be completely degraded, for example, in biological sewage treatment plants.

Gelling agents are usually made from multiple sugars or vegetable and animal proteins. Typical gelling agents are, for example, agar-agar, alginic acid, ammonium alginate, calcium alginate, potassium alginate, sodium alginate, pectin, amidated pectin, carrageenan, furcellaran, gelatin, gellan, guar gum, gum arabic, locust bean gum, karaya, propylene glycol alginate, tara gum, tragacanth or xanthan gum.

Preferably, however, only gelling agents from vegetable or animal proteins are used in the invention used to avoid that sugar-containing agents are used for the drug carrier according to the invention. It can indeed be expected that, especially with regard to the world food situation, the use of sugar to scent laundry will be denounced.

According to the invention, the solubility or dispersibility of the active ingredient carrier is set such that cold water can also be provided for the dispensing process.

The gelatinous gelatinizing compound formed to form the active substance carrier can be prepared, for example, for insertion into a corresponding washing or rinsing agent storage compartment, so that the gelation mass can be rinsed into the machine drum with a quantity of water intended for washing or rinsing purposes and dissolved during the rinsing process.

Preferably, however, the gelatinization compound is designed such that it can already be inserted at the beginning of a wash or rinse cycle or at the beginning of all washing or rinsing cycles in the machine drum provided with textiles, where it can be dissolved by the quantities of water soaked in washing or rinsing.

In a preferred embodiment, the gelling mass is portioned to a drug carrier having a volume of more than one cubic centimeter to about seven cubic centimeters and a perfume content of at least 1 gram, preferably more than 2.5 grams. In this way, the drug carrier can be given a format by means of which it can be added to the washing or rinsing agent storage compartment of a washing machine or directly to its machine drum. Nevertheless, it is achieved with the proposed perfume content that the fragrances can be distributed to a sufficient extent in a quantity of water flushed in for washing or rinsing purposes.

Furthermore, it is proposed that the gelation mass is portioned to a drug carrier, which is surrounded on all sides by a water-soluble coating layer. For this purpose, it is conceivable that the gelation composition has a gel-like consistency by the use of a gelling agent according to the invention and the coating layer consists of a gelling compound according to the invention which has a rather gummy consistency.

By such a measure, the coating layer can be formed for example of a water-soluble blister pack, which may for example consist of a gelatin capsule. In addition, it can also be achieved with the proposed coating layer that the fragrances do not prematurely separate from the gelatinizing compound, especially when the packaging is open. Advantageously, therefore, the coating layer is preferably free of fragrances.

As already mentioned above, the gelling agent can form, for example, a pourable solution together with a liquid perfume concentrate. The solution solidifies by the effects of the gelling agent to the gelatinous gelling mass according to the invention. According to the invention, therefore, the gelling compound can be formed by means of a mold to the functional support. It is conceivable that the mold at least partially also forms the water-soluble coating layer. Such a coating layer may, for example, be prepared in such a way that it has an upper-side opening in which the gelling compound can be poured in still liquid form in order to gelatinize there. The opening can then be closed, for example, with a lid, which is welded to, for example, the coating layer.

Furthermore, it is proposed that the gelling mass contains textile treatment agent. Preferably, the respective textile treatment agent contains vegetable extracts. With such a textile treatment agent, for example, textile fibers can be smoothed. The so-smoothed fibers make the textiles, especially after washing or ironing over and over again and longer, look new, shiny and supple. In particular, bamboo and / or calendula extracts are particularly suitable for this and are therefore preferably used.

In addition, other additives, such as stabilizers or plasticizers, can be added to the gelling compound.

Furthermore, the gelling compound may also be colored by means of coloring agents. In this case, especially colorations are considered, with which a likelihood of confusion of the active ingredient carrier according to the invention with confectionery, for example from wine gum, is not given.

For a particularly preferred embodiment of the invention, it is proposed that the gelling compound be shaped into three-dimensional fresh symbols, namely flowers, flowers or the like. Such symbols can be formed particularly easily due to the invention by means of casting.

In the following the invention will be explained in more detail by means of exemplary embodiments.

Unless otherwise stated below, the following description applies to all figures.

Especially Fig.1 shows an automatic washing machine 2 with a machine drum 5. In the machine drum 5 are garments 7, which are exposed to a washing or rinsing liquor, which is enriched with fragrances. For the production of such a washing or rinsing liquor in the machine drum 5, water-soluble active substance carriers 1 are used. For this purpose, the active substance carrier 1 fragrances 6 and are exposed during a wash or rinse cycle or during the final rinse phase, a flushed for washing or rinsing purposes amount of water. As a result, the garments 7 can be provided with fragrances 6 in sufficient quantities, without the risk that a portion of the supplied perfume 6 is washed out again with the washing process.

According to the invention, the active ingredient carrier 1 is formed from an amount of gelatin-containing gelatinizing mass 3 obtained in such a quantity, which disperses this amount in the amount of water introduced into it or dissolves completely there.

From the invention, it is possible, for example, to add a gelling agent to a liquid fragrance concentrate or a liquid fragrance solution in order to obtain a moldable gelling compound. which forms gelatinous according to the invention. The gelling compound can be introduced, for example, in prepared molds in the still liquid state to solidify there to a gelatinous drug carrier 3. especially the Fig.1 and Fig.2 show for this purpose an inventively formed drug carrier in a circular cylindrical tablet form. By type and concentration of the gelling agent used, the functional support 1 has a rubber-like consistency.

From the invention results in the particular advantage that procedures for producing a drug body 1 according to the invention can be used, which have been known for a long time, for example in confectionery production. Press forces, such as those used to make solid tableted rinse tablets of the prior art, are not required here.

For the preparation of a drug carrier 1 according to the invention a circular cylindrical shape was selected in the examples shown. However, the invention also makes it possible to give the functional support 1 in a simple way more complex three-dimensional shapes.

For this purpose, it is provided that the gelling compound 3 is formed into three-dimensional fresh symbols. Fresh symbols are understood to mean, for example, representations of flowers, flowers or citrus fruits and the like.

Since, according to the invention, the active substance carrier 1 is dispersed or completely dissolved in washing or rinsing purposes of the flushed-in amount of water, it is ensured that sufficient fragrances 6 are present in the washing or rinsing liquor obtained for ventilating the clothes 7 located in the machine drum 5.

In particular, by choosing a suitable gelling agent and its mixing ratio, e.g. With a perfume solution, a liquid perfume concentrate or a similar liquid with fragrances, cold water can also be provided for the flushing process, since the amount of gelatinous gelatinizing compound 3 used is completely dissolvable even during the flushing process with only cold water.

By adding it to the detergent storage compartment 8 of the washing machine 2, the gelation mass 3 molded to the functional unit 1 can be flushed into the machine drum 5 with a quantity of water flushed in for washing or rinsing purposes, where it then completely dissolves during the flushing process.

Preferably, the gelling mass 3 is already inserted into the machine drum 5 at the beginning of all washing or rinsing cycles in order to be completely dissolved there in a continuous manner by the quantities of water soaked in for washing or rinsing purposes.

In the exemplary embodiments shown, the gelation compound 3 is portioned to a drug carrier 1 with a volume of more than 1 cubic centimeter to about 7 cubic centimeters. The portioned gelling mass 3 in this case has a perfume content of at least 1 gram, preferably more than 2.5 grams. By this measure, it is ensured that the functional support is optionally inserted into the detergent dispenser 8 or in the machine drum 5 and has a sufficiently large amount of fragrance to obtain the washing or rinsing solution.

Especially Figure 3 shows a preferred embodiment of the invention, in which the gelling compound 3 to a drug carrier 1 is portioned, which is enclosed on all sides by a water-soluble coating layer 4. The water-soluble coating layer 4 prevents premature separation of the fragrances 6 from the gelatinous gelation compound 3. It is conceivable that the coating layer 4 is also formed by a gelatinous gelation compound 3, which in this case expediently contains no fragrances 6 and possibly by adding a suitable gelling agent in a corresponding ratio has a firmer consistency, as provided with the fragrances 6 by the coating layer 4 enclosed gelling 3.

Furthermore, it is conceivable that the wrapping layer 4 is formed by a water-soluble blister pack. It would be conceivable, for example, a gelatin capsule as a wrapping layer. 4

In addition to this, it is furthermore conceivable that the wrapping layer 4 is designed in several parts. For this purpose, for example, form a lower part of a mold, which is open at the top and can be closed on all sides with an upper lid part. In this way, for example, a weldable blister pack can be formed into which the gelatinous gelatinizing compound 3 can then be introduced before welding.

Preferably, gelling agents prepared from vegetable or animal proteins were used for the preparation of the active ingredient carrier 1 according to the invention. Among other things, this measure can ensure that the active substance carrier 1 contains no sugar-containing agents, in particular glucose-containing agents. This avoids that sugar can accumulate on garments 7 during a washing or rinsing process. Furthermore, this takes account of the world food situation, in which no sugar is used according to the invention for perfuming garments 7.

The gelling mass 3 preferably contains textile treatment agents. Textile treatment agents may contain, for example, vegetable extracts. By using vegetable extracts such as bamboo and / or calendula extracts, for example, the fibers of the garments 7 can be smoothed so that the garments 7 look longer, shiny and supple after washing. Likewise, the tensile strength of the garments 7 can also be increased by such an insert.

In addition to textile treatment agents, the gelling compound 3 molded into the active substance carrier 1 may also contain further additives. Stabilizers and plasticizers are proposed as further additives for this purpose.

Furthermore, it is proposed that the gelling compound 3 is colored. The coloring of the gelling compound 3 can serve, for example, to support a desired three-dimensional fresh symbol shape of the functional carrier 1 in color. In a particular embodiment, the active ingredient carrier 1 should resemble a flower, which should result in the dishwashing product according to the invention not only becoming aesthetically attractive but also odorally attractive.
