Description

 Process for the preparation of bitter-bodied enamel bodies

The present invention relates to a process for the preparation of perfume-containing fusible materials comprising at least one water-soluble or water-dispersible carrier polymer having a melting point> 30 ° C, at least one fragrance and at least one bittering agent, comprising the process steps described herein and the partum containing so produced

Melting body.

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.

Such fragrance particles are usually provided in the form of perfume-containing enamel bodies in batch processes. Such perfume-containing molded articles made from melts require during production that the perfume is exposed to higher temperatures. The

Finished product melt is then transferred by cooling into a shaped body. any

Production disruptions lead to the melt having to spend a long time at higher temperatures. This can lead to the degradation of thermolabile components, such as some

Perfume ingredients lead. In addition, the melting of the ingredients of the molded body including the perfume already leads to the fact that the latter is exposed to unnecessarily long high temperatures, which may also be disadvantageous for the reasons mentioned above.

In order to prevent the oral absorption of the shaped bodies, motivated by an appealing packaging and in particular the pleasant fragrance of the shaped bodies, it is customary to mix such compositions with bitter substances. On the one hand, the incorporation of sufficiently high amounts of bittering agent is often difficult, on the other hand it is general it is desirable to reduce as much as possible the amounts of raw materials used, including the bitter substances, without impairing their effectiveness.

The object of the present invention was therefore to provide a method which the

Making partum- and bitter-containing enamel body allows and at least partially overcomes the known problems.

The object has been achieved according to the invention by a process in which the bitter substance is not metered into the melt but onto the surface of the perfume-containing product produced

Melt body is applied.

In a first aspect, the present invention is therefore directed to a process for preparing partum- and bitter-containing enamel bodies comprising at least one

water-soluble or water-dispersible carrier polymer having a melting point> 30 ° C to 250 ° C, preferably> 40 ° C to 150 ° C, preferably selected from polyalkylene glycols, more preferably polyethylene glycol, at least one perfume and at least one bittering agent, said method comprising the following steps :

 (a) preparing a perfume-containing fusible body; and

 (b) applying the at least one bittering agent to the surface of the fused body obtained after step (a), wherein the bittering agent is preferably applied in the form of a solution, in particular sprayed on.

In a further aspect, the present invention is directed to the thus obtained

perfume-containing enamel body and its use as a textile care agent, preferably fragrancing agent and / or softener, for perfuming and / or conditioning textile fabrics, or as an additive in a washing or cleaning agent.

Another component of the enamel body is at least one perfume. A fragrance is an odor-causing chemical substance. To the sense of smell to stimulate the chemical substance should be at least partially distributed in the air, ie the perfume should be volatile at 25 ° C, at least to a small extent. If the fragrance is now very volatile, the odor intensity then quickly decreases again. At a lower volatility, the smell impression is more sustainable, ie it does not disappear so quickly. 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.

For solvents from the group of alcohols and glycols are concentrations in the range of 15 to 35 wt .-%, in particular 20 to 30 wt .-%, preferably 25 to 30 wt .-% bittering agent, based on the total weight of the solution.

The solvent (s) used may be removed after evaporation of the at least one bittering agent on the surface of the fusible elements.

If the at least one bitter substance is applied to the surface of the enamel bodies prepared according to the invention as described above, an application rate of already 0.5 to 10 mg, preferably 1 to 7 mg, in particular 1.5 to 5 mg, most preferably 2 to 3 mg per kg of enamel body sufficient to ensure a sufficient denaturation of the enamel body.

The application of the at least one bittering agent to the enamel body obtained according to step (a) of the process according to the invention can be carried out by means of various application methods of liquids to surfaces known in the art. For example, the application of the at least one bittering agent, in pure form or in the form of a solution, without limitation, by spraying the at least one bittering agent on the surface of the fusible body, preferably by fine atomization of the at least one bittering agent, in particular two-fluid nozzles can be advantageously used ,

In various embodiments in which the bittering agent is applied in the form of a solution, the solvent is subsequently evaporated. The evaporation preferably takes place before the further processing of the fusible bodies, i. in a continuous process before they are dropped by a conveyor. In various embodiments in which the production / shaping of the shaped bodies takes place by means of a pastillating roll, the bittering agent is applied after this shaping, usually sprayed in the form of a solution. After the spray station, one or more of these may be used in such processes

Drying hoods are arranged, which dry the moldings by means of IR or hot air.

In various embodiments, the bittern is applied only to a portion of the surface of the fuser. For example, in the case of hemispherical particles lying flat on a conveyor belt, this may be the spherical top onto which the bittering agent is sprayed. Alternatively, however, only the underside can be coated, for example, if the application / spray device is arranged so that the particles are sprayed from the bottom or dropped onto a surface sprayed with the bittering agent (usually in the form of a solution).

For spraying, for example, a spray lance can be used. This is a straight pipe mounted parallel to the conveyor, usually a conveyor, and comprising one or more nozzle heads directed at the belt.

According to the present invention, those bitter substances are particularly preferred which are soluble in water at 20 ° C to at least 5 g / l. With regard to an undesirable interaction with the fragrance components also contained in the melting bodies, in particular a change in the scent perceived by the consumer, the ionogenic bitter substances have proved superior to the nonionic, ionogenic bitter substances consisting of organic cation (s) and organic (n) anion (s) are therefore preferred for the fused article produced by the process according to the invention. Thus, in various embodiments, the at least one bittering agent is an ionogenic bittering agent.

Quaternary are outstandingly suitable in the context of the present invention

Ammonium compounds containing an aromatic group in both the cation and the anion. Thus, in various embodiments, the at least one bittering agent is a quaternary ammonium compound.

A suitable quaternary ammonium compound is, for example, without limitation, commercially available e.g. Benzyldiethyl ((2,6-xylylcarbamoyl) methyl) ammonium benzoate available under the trade names Bitrex® and Indige-stin®. This compound is also known by the name Denatonium Benzoate.

In various embodiments, the at least one bittering agent is benzyldiethyl ((2,6-xylylcarbamoyl) methyl) ammonium benzoate (Bitrex®).

It is also possible to use amorphous sodium silicates with a Na ₂ O: SiO ₂ modulus of from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8, and in particular from 1: 2 to 1: 2.6. In the context of this invention, the term "amorphous" is understood to mean that the silicates do not yield sharp X-ray reflections typical of crystalline substances in X-ray diffraction experiments, but at most one or more maxima of the scattered X-rays having a width of several degrees of diffraction angle , cause.

Alternatively or in combination with the abovementioned amorphous sodium silicates, X-ray-amorphous silicates are used whose silicate particles give washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of the size of ten to a few hundred nm, with values of up to max. 50 nm and in particular up to max. 20 nm are preferred. Such X-ray amorphous silicates also have a dissolution delay compared to conventional water glasses. Particularly preferred are compacted / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates.

Particularly preferred according to the invention are polysilicic acids, clay minerals such as montmorillonites and zeolites.

It may furthermore be particularly preferred if a montmorillonite-based clay mineral, in particular a bentonite, is used as the silicate. Another suitable clay material is, for example, a smectite clay. Preferred smectite clays are beidellite clays, hectorite clays, laponite clays, montmorillonite clays, nontronite clays, saponite clays, sauconite clays, and mixtures thereof. Montmorillonite clays are the preferred clays. Bentonites contain mainly montmorillonites and may serve as a preferred source of the inorganic solids of the present invention. The bentonites can be used as powder or crystals.

Suitable bentonites are sold, for example, under the names Laundrosil® by Süd-Chemie or under the name Detercal by Laviosa.

In a preferred embodiment, the solid compositions contain as

inorganic solid at least one inorganic salt selected from the alkali metal or alkaline earth metal salts, in particular the carbonates, sulfates, halides or phosphates and mixtures thereof. Particular preference is given to using sodium sulfate and / or sodium carbonate.

The alkali metal and alkaline earth metal salts, preferably the sodium sulfate, may be present in an amount of up to 30% by weight, preferably from 0.01 to 30% by weight, particularly preferably from 10 to 25% by weight, in particular from 18 to 22% by weight.

In various embodiments, the perfume-containing fusible article as described herein may further comprise at least one fabric-conditioning compound. In this context, a textile care compound is understood to mean any compound which gives textile fabrics treated therewith a beneficial effect, such as, for example, a textile softening effect, crease resistance or the harmful or negative effects which result during cleaning and / or conditioning and / or or wearing, such as

Fading, graying, etc., reduced.

The fabric care composition may preferably be made of fabric softening compounds, bleaches, bleach activators, enzymes, silicone oils, anti redeposition agents, optical brighteners, grayness inhibitors, anti-shrinkage agents, wrinkle inhibitors, color transfer inhibitors, antimicrobials, germicides, fungicides, antioxidants, antistatic agents, ironing aids, phobizers and the like Impregnating agents, swelling and slipping agents, UV absorbers and mixtures thereof are selected.

It is particularly preferred that the fabric care compound is a fabric softening compound. It is most preferred that the fabric softening compound is selected from polysiloxanes, fabric softening clays, cationic polymers and mixtures thereof.

The use of polysiloxanes and / or cationic polymers as textile-care compound in the melt bodies is advantageous because they not only have a softening effect but also enhance the perfume impression on the linen. The use of softening clays as textile-care compound in the melt bodies is advantageous because they additionally have a water-softening effect and so, for example

Lime deposits on the laundry can be prevented. To achieve optimum performance, it may be preferred for a fuser to contain a combination of at least two fabric care compounds.

When the enamel body produced according to the invention contains such textile-care compounds, they are used in particular as a fabric care or fabric softener or as a component of such an agent or else as a constituent of a detergent.

Such a fabric conditioner may be in the main wash of an automatic washing or

Cleaning process can be used. The fusible bodies can be added, for example, together with the washing or cleaning agent into the drum or the dispensing chamber of a washing machine. This has the advantage that no additional rinse is necessary and no unsightly deposits occur in the dispenser

Furthermore, such a solid fusible body in the wash a

 Laundry cleaning process can be used and so the textile-care compound and the perfume already at the beginning of the washing process to transport laundry, so as to be able to develop their full potential. Furthermore, this enamel body is easier and better to handle than liquid compositions, since no drops remain on the edge of the bottle, which lead to subsequent storage of the bottle to edges on the ground or to unsightly deposits in the region of the closure. The same applies in the event that something of the enamel body is accidentally spilled during dosing. The spilled amount can also be removed easier and cleaner.
