Definitions
- the present invention relates to particles which contain certain inorganic carrier material in a minimum amount of 30% by weight, perfume and nonionic surfactant (s) in amounts of at least 0.1% by weight, a process for producing such particles, a detergent composition containing such particles and a method for washing textiles with the aid of this detergent composition.
- the detergents and post-treatment agents serve to give the washing or rinsing solution itself, but also the textile goods treated with the washing or rinsing solution, a pleasant fragrance to lend.
- the scenting of detergents, cleaning agents and post-treatment agents is an important aspect of the aesthetic product impression and an important point in the consumer decision for or against a specific product.
- the perfume can either be incorporated directly into the agents or added to the washing or rinsing solution in an additional step.
- the first way specifies a certain product characteristic, while the second way, the consumer can individually decide on "his" fragrance from the different fragrance options on offer, comparable to choosing an eau de toilette or an aftershave.
- DE 41 33 862 discloses tablets which contain carrier materials, fragrances and, if appropriate, further ingredients customary in washing and cleaning agents, sorbitol and additionally 20 to 70% by weight of a carbonate and acid bubbling system being used as carrier material.
- These tablets which can be added, for example, to the rinse and fabric softener in a household washing machine, contain about 3 to 15, preferably 5 to 10,% by weight of fragrance. Due to the high disintegrant content of the tablets, they are sensitive to atmospheric moisture and must be stored appropriately protected.
- DE 39 11 363 discloses a process for producing a washing or rinsing liquor enriched with fragrance and a fragrance addition agent used for this purpose.
- the addition agents which are in the form of capsules or tablets, contain the fragrance together with an emulsifier in liquid form (capsules) or bound to fillers and carriers (tablets), sodium aluminum silicates or cyclodextrins being mentioned as carriers.
- the fragrance content of the capsules or tablets is at least 1 g, the volume of the compositions being over 1 cm 3 . Tablets or capsules with more than 2.5 g of fragrance and a volume of at least 5 cm 3 are preferred. During storage, such tablets or capsules must be provided with a gastight and watertight coating in order to protect the ingredients. Further details on the production and the physical properties of suitable tablets are not contained in this publication.
- the international application WO 94/25563 (Henkel-Ecolab) describes a process for the production of washing and cleaning-active moldings using microwave technology, which works without high pressure pressing.
- the molded articles produced in this way are distinguished by an extremely high dissolving speed or disintegration speed with simultaneous breaking strength, without the need for an explosive. At the same time, they are stable in storage and can be stored without additional precautions.
- moldings which have a perfume oil content which is customary for detergents and cleaning agents and between 1 and 3% by weight.
- Perfume oils are generally volatile and could therefore evaporate under the influence of microwave radiation. If higher proportions of volatile liquid substances are to be used, a two-component system consisting of a component produced using microwave technology and a component containing the sensitive liquid substances is therefore described.
- Particulate additives for scenting washing liquors and for use in detergents and cleaning agents and processes for their preparation are described in international patent applications WO97 / 29176 and WO97 / 29177 (Procter & Gamble). According to the teaching of these documents, porous carrier materials (for example sucrose in a mixture with zeolite X) are mixed with perfume and finally coated with a coating material (carbohydrates) and brought to the desired particle size distribution.
- a coating material for example sucrose in a mixture with zeolite X
- German patent application DE 197 35 783 A1 (Henkel) describes high-dose perfume moldings which contain carrier material (s), 20 to 50% by weight of fragrance (s) and, if appropriate, other active substances and auxiliaries customary in washing and cleaning agents , wherein the moldings after deduction of the amount of fragrance at least 50 wt .-% of their weight consist of fatty acids and fatty acid salts.
- These perfume moldings are suitable for scenting detergents and cleaning agents as well as for scenting textiles in a washing machine.
- a method for applying fragrances to textile goods in a washing machine is described in DE 195 30 999 (Henkel).
- a fragrance-containing molded body which is produced by irradiation with microwaves, is used in the rinse cycle of a washing machine.
- the preferably spherical shaped bodies with diameters above 3 mm and bulk densities of up to 1100 g / l can be produced by filling a mixture of predominantly water-soluble carriers, hydrated substances, optional surfactants and perfume into suitable molds and with With the help of microwave radiation sinters.
- the fragrance contents of the shaped bodies are between 8 and 40% by weight, starches, silicas, silicates and disilicates, phosphates, zeolites, alkali salts of polycarboxylic acids, oxidation products of polyglucosans and polyaspartic acids are used as carriers.
- a prerequisite for the shaped body manufacturing process described in this document is that the mixture which is sintered into shaped bodies with the aid of microwave radiation has at least partially bound water, i.e. some of the starting materials are in hydrated form.
- the invention relates to a particle which contains inorganic carrier material selected from the group comprising zeolites, sulfates, carbonates, silicates, silicic acid and / or mixtures thereof, and also perfume which is adsorbed on the carrier material and / or absorbed in the carrier material. the particles containing at least 0J% by weight of nonionic surfactant (s), based on the total particles.
- the carrier material is preferably impregnated with the nonionic surfactant, i. H.
- the nonionic surfactant is advantageously essentially distributed in the carrier material and, in particular, essentially not enriched on the surface of the carrier material.
- the particles according to the invention in comparison with corresponding particles without a nonionic surfactant, lead to a more intensive fragrance experience for the consumer, for example when washing laundry with a detergent formulation which contains the particles according to the invention. It has surprisingly been found that the consumer perceives a more intense scent of the washed laundry compared to laundry which was washed with a conventionally perfumed detergent formulation, even if the absolute amount of the perfume contained was the same. To this extent, the invention achieves a fragrance-enhancing effect which directly affects the particles, and objects into which these particles are incorporated, for example detergent formulations, and things such as B. Textiles, which are treated with the objects (here: detergent formulation).
- Another advantage of the particles according to the invention is, surprisingly, that the perfume component incorporated in the particle is stabilized in comparison to an otherwise comparable particle in which no nonionic surfactant is contained. It is often the case that perfume, which is incorporated in a carrier material, at least partially decomposes more or less slowly in the carrier material. In contrast, this decomposition is at least delayed in a particle according to the invention.
- a perfume-stabilizing effect is thus achieved by the invention. This is especially true when the particle is incorporated into an object, such as. B. in a detergent formulation, which is rather detrimental to the stability of perfume due to its object property, for example its alkalinity.
- the perfume-stabilizing effect has a particularly favorable effect.
- the scent impression resulting from the particles according to the invention lasts indirectly and immediately longer.
- “Immediate” in this context means that the particle according to the invention smells for a longer period than an otherwise comparable particle which, however, does not contain any nonionic surfactant, but does contain the same amount of perfume.
- “Indirect” in this context means that objects (e.g. Detergent formulation) which contain the particles according to the invention have a longer fragrance, and that even when these objects are used (for example detergent formulation for washing textile), the things treated with them (here: washed textile) have a longer fragrance.
- the invention therefore achieves a fragrance (impression) with a sustained-release effect, this fragrance-retarding effect (ie the temporal expansion of the fragrance impression) both on the particles and on the objects containing particles and on those with them Related objects.
- a great advantage of the invention is also surprisingly that the addition or the presence of nonionic surfactant makes it possible to load the carrier material of the particles with larger amounts of perfume. If there is no non-ionic surfactant, only smaller amounts of perfume can be absorbed. This is particularly surprising because it should be assumed that the amount of perfume that can be absorbed by the carrier material would have to decrease if the carrier material also has to absorb a certain amount of another substance. An improvement, in particular even a maximization of the perfume absorption capacity of the carrier material is thus achieved by the invention, so that perfume loading of the carrier material becomes possible to an extent which could not be achieved previously (in the absence of the nonionic surfactant).
- perfume means perfume oils, fragrances and fragrances.
- Individual fragrance compounds for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as perfume oils or fragrances.

- perfume oils can also contain natural fragrance mixtures as are available from plant sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are muscatel sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.
- a fragrance In order to be perceivable, a fragrance must be volatile, in addition to the nature of the functional groups and the structure of the chemical compound, the molar mass also plays an important role. Most odoriferous substances have molecular weights of up to about 200 daltons, while molecular weights of 300 daltons and more are an exception. Due to the different volatility of odoriferous substances, the smell of a perfume or fragrance composed of several odoriferous substances changes during evaporation, whereby the odor impressions are described in "top note”, “heart or middle note” (middle note or body) and “base note” (end note or dry out). Since the smell is largely based on the intensity of the smell, the top note of a perfume or fragrance does not consist solely of volatile compounds, while the base note largely consists of less volatile , ie there are strong odoriferous substances.
- Adhesive odoriferous substances which can advantageously be used in the context of the present invention are, for example, the essential oils such as angelica root oil, anise oil, arnica flower oil, basil oil, bay oil, bergamot oil, champagne flower oil, noble fir oil, noble pine cone oil, elemi oil, eucalyptus oil, fennel oil, fennel oil, fennel oil, fennel oil , Geranium oil, ginger grass oil, guaiac wood oil, gurjun balsam oil, helichrysum oil, ho oil, ginger oil, iris oil, kajeput oil, calamus oil, chamomile oil, camphor oil, kanaga oil, cardamom oil, cassia oil, chamomile oil, kola pomace oil, cumin oil, coriander oil, coriander oil, coriander oil, coriander oil, coriander oil - Del oil, lemongrass oil, lime oil, mandarin oil
- the higher-boiling or solid odoriferous substances of natural or synthetic origin can also advantageously be used in the context of the present invention as adhesive odoriferous substances or odorant mixtures, that is to say fragrances.
- These compounds include the compounds mentioned below and mixtures of these: ambrettolide, ⁇ -amyl cinnamaldehyde, anethole, anisaldehyde, anis alcohol, anisole, anthranilic acid methyl ester, acetophenone, benzylacetone, benzaldehyde, ethyl benzoate, benzophenone, benzyl alcohol, benzyl acetate, benzyl formiatate, benzyl formiatate, benzyl formate benzate - nat, borneol, bornyl acetate, ⁇ -bromostyrene, n-decylaldehyde, n-dodecylaldehyde,

- the delay in dissolution compared to conventional amorphous sodium silicates can be caused in various ways, for example by surface treatment, compounding, compacting / compression or by overdrying.
- the term “amorphous” is also understood to mean “X-ray amorphous”.
- silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle.
