Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD The present invention relates to a shaped article having a high fragrance content. The shaped articles of the present invention can be incorporated into detergents and compositions for treating and post-treating textiles, and have a perfume content of at least 20% by weight, preferably at least 30% by weight, based on the shaped article.

BACKGROUND OF THE INVENTION In the washing, treatment and post-treatment of textile products, it is presently customary to add small amounts of perfume to detergents and post-treatment compositions, the purpose of which is to use washing or rinsing liquids. It also imparts a pleasant scent to textiles treated with such a liquid. For detergents and post-treatment compositions, in addition to color and appearance, incense is also an aesthetically important factor and an important factor in attracting consumers. For flavoring, the perfume may be incorporated directly into the detergent or post-treatment composition, or may be added separately to the washing or rinsing liquid. In the former case of these two possibilities, the properties of the product are determined. In the latter case, the consumer can personally select the fragrance from a variety of fragrances (similar to choosing an eau de toilette or aftershave lotion).

[0003] Perfume shaped articles and methods of flavoring washing and rinsing liquids are widely described in the prior art. DE 4133862 (Henkel) contains carrier materials, fragrances and optionally other conventional detergent ingredients, and contains sorbitol and a 20-70% by weight foaming system (
Shaped articles using carbonates and acids) as carrier materials are disclosed.
The shaped article can be added, for example, to the final rinse and textile softening cycle of a home washing machine and contains about 3 to 15%, preferably 5 to 10% by weight of fragrance. The shaped article is sensitive to moisture in the air because of its high disintegrant content and therefore requires protection for storage.

[0004] DE3911133 (Baron Freytag von Loringhoven) describes a process for the preparation of a washing or rinsing liquid with a high perfume content and a perfume-containing medium suitable for that purpose. This addition medium is present as a capsule or tablet and contains a liquid emulsifier together with the fragrance (in the case of capsules) or a bulking agent and the fragrance fixed on a carrier (in the case of tablets). Carriers include sodium aluminum silicate and cyclodextrin. The capsule or tablet has a flavor content of at least 1 g, and the capsule or tablet has a volume of more than 1 cm ³ . Tablets or capsules having a volume of at least 5 cm ³ and a perfume content of more than 2.5 g are preferred. Storage of such tablets or capsules requires the provision of a gas and water impermeable coating for component protection. The above references do not give further detailed formulas or physical properties for suitable tablets.

[0005] DE 195 30 999 (Henkel) also describes a method for applying perfume to textiles. In this method, a perfume-containing shaped article produced by microwave treatment of a mixture of a porous carrier material, a hydration material, and a partially liquid perfume formulation is used in the final rinse cycle of a washing machine. The fragrance content of the shaped article is 8
４０40% by weight. As carrier materials, starch, silica, silicates and disilicates, phosphates, zeolites, alkali metal salts of polycarboxylic acids, polyglucosan oxidation products, and polyaspartic acid are used. International patent application WO 94/25563 (Henkel-Ecolab) describes a method for producing detergent shaped articles by microwave methods without high-pressure tableting. Tablets produced by this method have a very high solubility or disintegration without a disintegrant,
And it is break resistant. Moreover, it is storage-stable and can be stored without further precautions. By this method it is also possible to produce tablets having a usual perfume oil content of 1 to 3% by weight in detergents.

[0006] Perfume oils are usually volatile and can be evaporated by microwave irradiation. Therefore, if a relatively high level of a volatile liquid material is to be used, a two-component system consisting of a component produced by a microwave method and a component containing a sensitive liquid material is required.

DISCLOSURE OF THE INVENTION Technical Problem to be Solved by the Invention The problem of the present invention is that despite the fact that it can contain at least 20% by weight of perfume,
It is an object of the present invention to provide a shaped article having a high fragrance content, which does not require a gas- and water-impermeable coating layer or pack for protecting the components during storage. Another object of the present invention is to provide a fragrance supply form that can be blended as a component in a normal detergent and can also be used directly in home laundry so that a fragrance can be selected personally. Met.

(Solution method) [0008] A mixture of a fatty acid and a fatty acid salt is used as a carrier material, and the fragrance content is 20 to 5%.
It was found that when the content was 0% by weight, it was possible to produce a shaped article having a high fragrance content which was versatile.

The present invention relates to a shaped article with a high perfume content comprising a carrier material, a perfume and optionally other active ingredients and auxiliaries normally present in a detergent, wherein a) the perfume content of the shaped article is reduced. B) a perfume-rich shaped article comprising 20-50% by weight, based on the weight of the shaped article, and b) at least 50% by weight of the shaped article weight after subtracting the amount of perfume comprises fatty acids and fatty acid salts. In a preferred embodiment of the present invention, the perfume content of the shaped article having a high perfume content is 2%.

Perfume beads are particularly suitable for incorporation into perfumed products, and perfume tablets are preferred for consumers to personally perfume textiles.

In the present invention, the “carrier material” includes any non-perfume material used in the shaped article of the present invention. According to the invention, a mixture of fatty acids and fatty acid salts and optionally other components is used as carrier material for the perfume. The content of fatty acids and fatty acid salts in the carrier material must be at least 50% by weight of the carrier material weight. According to the invention, the preferred shaped article with a high perfume content comprises 30-70% by weight of fatty acids and fatty acid salts, preferably 35-60% by weight, more preferably 40% by weight.
-50% by weight. In the present invention, "a mixture of a fatty acid and a fatty acid salt and, if necessary, other components" refers to a mixture of the fatty acid or the fatty acid salt with 5 to 9
It is understood that this means a mixture containing 5% by weight, but at least 50% by weight of the carrier material must consist of fatty acids and fatty acid salts. According to this, the ratio of fatty acid to fatty acid salt is 1:19 to 19: 1. In the preferred high perfume content shaped article of the present invention, the non-perfume material contains 15 to 35% by weight, preferably 20 to 25% by weight, of one or more fatty acids, based on the tablet.

Fatty acids that are not solid at room temperature (ie, pasty or liquid) may be used as fatty acids. However, from a performance standpoint, fatty acids that are solid at room temperature are clearly preferred over other fatty acids. Fatty acids can be saturated or mono- or polyunsaturated depending on the state of the material. Also in the case of unsaturated fatty acids, those which are solid at room temperature are preferable to those which are liquid or paste.

It has been achieved in various ways such as compression or overdrying. In the present invention, "amorphous" is understood to include "X-ray amorphous". In other words, the X-ray diffraction analysis indicates that the silicate does not exhibit the sharp X-ray reflection characteristic of crystalline materials, but only one or more scattered X-ray maxima with a diffraction angle width of several degrees. Means But,
Particularly good builder performance can also be achieved if the silicate particles show a weak or sharp diffraction maximum in electron diffraction analysis. This can be interpreted to mean that the silicate has microcrystalline parts with a size of ten to several hundred nm. This value is preferably up to 50 nm, especially up to 20 nm. Such so-called X-ray amorphous silicates which have a delayed dissolution as compared to normal water glass are described, for example, in German Patent Application DE-A-4400024.

In addition to or instead of the conventional bleach activators mentioned above, so-called bleach catalysts may also be incorporated into the shaped articles. The bleaching catalyst is a transition metal salt or a transition metal complex having a bleach-enhancing action, for example, a manganese-, iron-, cobalt-, ruthenium- or molybdenum-Salen complex, or a carbonyl complex. Manganese, iron, cobalt, ruthenium, molybdenum, titanium, vanadium and copper complexes, and cobalt-, iron-, copper- and ruthenium-ammine complexes with nitrogen-containing tridentate ligands may be used as bleach catalysts. .

Furthermore, the shaped article of perfume of the present invention may contain a component (so-called antifouling agent) having a positive effect on removing oil and fat from textiles by washing. This effect is particularly evident when soiling textiles that have already been repeatedly washed with the inventive detergents containing such oil and fat dissolving components. Preferred oil and fat dissolving components are, for example, nonionic cellulose ethers (e.g. methylcellulose and methylhydroxypropylcellulose having 15-30% by weight of methoxyl groups / 1-15% by weight of hydroxyproxyl groups, based on nonionic cellulose ether).

The fragrance shaped article of the present invention may be manufactured in any three-dimensional shape. In one preferred process, the carrier material and any optional components, if any, are melted at 30-80 ° C and stirred until a homogeneous melt is obtained. After adding the flavor and mixing, the melt is allowed to cool and solidify. Other optional ingredients may be incorporated into the melt before or after flavoring, and the heat-sensitive material is advantageously added just before the mixture reaches its freezing point.

It is of course possible and preferred to carry out the shaping / shaping of the heated plastic compound. That is, the plastic compound can be extruded, for example, from a porous die into a strand, which can be continuously cut and optionally rounded in a later step. The performance of the “perfume beads” thus obtained can be further improved by conventional surface treatment methods (eg powdering). While this form is suitable for incorporation directly into conventional detergents, it may be compressed (optionally as a mixture with other ingredients) to form a flavoring shaped article such as a tablet. The latter are suitable, for example, for applying fragrances to textiles in home washing machines.

The shaped article having a high perfume content of the present invention can of course be produced by other methods. In addition to the extrusion method described in detail above, for example, a method of granulating a fatty acid and a fatty acid salt with a fragrance and optionally used components, and a particulate fatty acid salt (optionally mixed with other components) and a fatty acid And a method of granulating pellets with the fragrance. The carrier material slurry can be spray dried and the fragrance sprayed on (again, optional ingredients may be present).

In another aspect, the present invention provides a shaped article having a high perfume content comprising a carrier material, a perfume, and optionally other active ingredients and auxiliaries normally present in detergents,
A mixture of a fatty acid and a fatty acid salt is used as a carrier material, and the fragrance content is 20 to 50.
It also relates to the use of shaped articles, which are in% by weight, for flavoring detergents.

In another preferred embodiment, the present invention also relates to a method of applying perfume to textiles by adding a perfume-containing solid shaped article during a washing or rinsing cycle in a washing machine. This method is a shaped article with a high perfume content containing a carrier material, a perfume and optionally other active ingredients and auxiliaries normally present in detergents, using a mixture of fatty acids and fatty acid salts as the carrier material. And adding the shaped article having a perfume content of 20 to 50% by weight to the wet laundry during the washing or rinsing cycle of the machine washing method in one piece or in divided form.

[0043] To illustrate the embodiments the present invention was produced shaped articles having the following composition:

[Table 1]

All components except the perfume oil were melted to form a homogeneous melt. Then add the balm,
The melt was cooled while stirring. The resulting formulation was extruded from a perforated die into strands to form perfume beads. The strand discharged from the extrusion die was cut into a length of 1 to 2 mm and rounded in a separate step. To improve the bead surface properties, the resulting beads were dusted with 2% by weight of rice starch, based on the weight of the beads.

This bead can be used as it is for flavoring the detergent. For that purpose, the beads can be incorporated into a solid detergent or dissolved in a liquid detergent. To provide the consumer with a product suitable for the flavoring of textile products, the beads are mixed with an additional 20% by weight (based on the weight of the tablets to be produced) of additional tableting aids (binders and disintegrants). To make tablets.
The product thus obtained, when introduced into a normal washing solution, quickly disintegrates completely and forms a perfume emulsion.

Another fragrance shaped article according to the present invention was produced. Its composition is as follows:

[Table 2]

A perfume shaped article was produced as described in the previous examples by converting all ingredients except the perfume oil to a homogeneous melt and adding the perfume oil to the substantially solidified melt.
