2. Description of the Related Art Automatic dishwashers have rapidly spread in recent years, and with the spread of dishwashers, the development of dedicated detergents has also been actively carried out. In the dishwasher detergent where the object to be washed is dishware, if the scent remains on the dish, it may affect the person who eats. There was no perfuming. In recent years, since many competitors have come to the market, fragrance has come to be used, including the taste of users and the meaning of differentiating products. However, the automatic dishwasher detergent uses a unique bleach component unlike other detergents, and the bleach component affects the fragrance component,
The fragrance component was decomposed, and it was difficult to keep the fragrance stable. It has been found that the reason for this is that most of the fragrance components have a functional group in the molecule, such as an ester bond or a double bond, which can be easily decomposed by the peroxygen compound of the bleaching agent. In order to solve this problem, in the case of clothing detergents and clothing bleaching agents, there is also a method of mixing perfume components in a state where they are included in β-cyclodextrin, or performing a special treatment on the surface of the peroxygen compound. Although proposed, all of these conventional methods have been unsatisfactory because of their disadvantages in terms of cost and inability to obtain a sufficient effect. Therefore, there has been a demand for the development of a composition in which a fragrance component is stably present in a detergent for automatic dishwashers containing a peroxygen compound and a fragrance, and which can maintain the fragrance for a long period of time.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a detergent composition containing a peroxygen compound and a fragrance, wherein the fragrance is stably present for a long period of time, and the fragrance can be released for a long period of time. It is to provide.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and have completed the present invention. That is, according to the present invention, there is provided a detergent composition containing a peroxygen compound (a component), a fragrance (b component), and an alkaline silicate and sodium aluminate (c component). Provided is a cleaning composition in which sodium aluminate is present on the surface of a granular material comprising a cleaning composition made of a component other than sodium aluminate.

[0005]

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a particulate peroxygen compound (a component) is used. For this compound, sodium percarbonate or sodium perborate is used. These compounds act as bleaching agents. Sodium percarbonate or sodium perborate is not particularly limited by its shape, properties, grade, etc., and commercially available ones can be suitably used, but the stability during storage and the powder flow when used as a detergent Considering the properties and stability of the aroma, in the case of sodium percarbonate, granular sodium percarbonate surface-treated with borate, etc., and in the case of sodium perborate, monohydrate rather than tetrahydrate It is preferred that The average particle size of the granules is 0.1 to 2 m.
m is preferable. If the particle size is smaller than 0.1 mm, the surface area becomes too large,
The chance of contact with enzyme granules and flavor components increases, and the stability during storage may be insufficient. In addition, the particle diameter is 2 m
If the particle size exceeds m, it is not preferable because when a product is used as a cleaning agent, classification tends to occur in the product due to a difference in particle size. When specifically preferred examples are given by trade name, SPC series such as SPC-D, Perbon (registered trademark, manufactured by Mitsubishi Gas Chemical Co., Ltd.) and the like are very suitable.

In the present invention, the fragrance is preferably incorporated in the detergent in a range of 0.01 to 1% by weight. 0.01% by weight
If the amount is less than the above, it is not possible to finish the product with a small fragrance effect and sufficient satisfaction for consumers. Also,
Even if the amount of the fragrance is larger than this range, the fragrance may be too strong and may cause discomfort to the consumer, and in some cases, the fragrance may remain on the main body of the washing machine or the object to be cleaned. There is also.

In the present invention, an alkaline silicate and sodium aluminate (component (c)) are used. In the present invention, the surfaces of these components are treated with alkaline silicate and sodium aluminate to avoid direct contact of the perfume and other components with the peroxygen compound. When such a treatment is performed, the surface and the vicinity of the surface of the granular material are covered with the alkaline silicate and the sodium aluminate from the fragrance component and other components, or a large amount of these substances are present. As a result, the fragrance component does not come into direct contact with the peroxygen compound, and the fragrance component can be stably present. When the cleaning agent is stored for a relatively long period, moisture existing in the air is absorbed. At such time, the alkaline silicate and sodium aluminate change as follows. That is, when sodium aluminate contacts water in the presence of an alkaline silicate, these materials undergo a hydrolysis reaction to produce silica. Since silica produced by this reaction has extremely low solubility in water, a silica barrier having low affinity for water is formed. As a result, the decomposition of the perfume component by the peroxygen compound is suppressed by using the silica as a barrier between the peroxygen compound and the perfume component. In other words, the alkaline silicate and sodium aluminate are interposed between the peroxygen compound and the fragrance component and try to prevent the influence of the peroxygen compound, but are not only affected by the moisture and other moisture. When this occurs, the alkaline silicate and sodium aluminate are converted into silica, which blocks water penetration, thereby forming a barrier that can prevent the effects of peroxygen compounds. Decomposition of the fragrance component by the peroxygen compound hardly proceeds under the condition without water. The decomposition of the fragrance causes moisture absorption when stored, and the active peracid generated when the moisture due to the moisture reacts with the peroxygen compound comes into contact with the fragrance to cause the decomposition reaction to proceed. Therefore, as described above, if the detergent particles containing the fragrance are coated with the alkaline silicate and sodium aluminate, even when moisture is absorbed, water is consumed for the hydrolysis reaction on the particle surface, Further, even if water tries to proceed into the particles, water is shut off because insoluble silica having the property of repelling water is formed on the surface. Therefore, the fragrance component is kept stable. The amounts of the alkaline silicate and sodium aluminate incorporated in the composition of the present invention are 0.5 to 15% by weight and 0.1 to 15% by weight, respectively.
~ 5% by weight. If the amount is less than 0.5% by weight, the hydrolysis reaction cannot proceed sufficiently, so that a sufficient barrier effect cannot be obtained and the flavor may not be kept stable. Conversely, if it exceeds 15% by weight, too much water-insoluble silica is generated, and after use, insoluble residues may adhere to the automatic dishwasher cabinet. The mixing ratio of the two is not particularly limited, but in order to effectively suppress the decomposition of the fragrance, the ratio of the alkaline silicate to sodium aluminate is 100: 1 to 5: 1. In order for the alkaline silicate and sodium aluminate to be present on the surface of the granules, granules of a detergent component other than the peroxygen compound and sodium aluminate are formed, and then formed on the surface of the granules. Treat in the presence of sodium aluminate. In order for sodium aluminate to be present on the surface of the granular material, the surface of the granular material comprising a peroxygen compound and a detergent component other than sodium aluminate is mixed and stirred so that sodium aluminate adheres. Also, the detergent components other than the peroxygen compound, sodium aluminate and the alkaline silicate are granulated to form granules, the alkaline silicate is adhered to the surface, and then the aluminate is further deposited on the surface. Sodium deposition is performed.

[0008] The detergent for an automatic dishwasher of the present invention can preferably contain various optional components generally used in the detergent. These components include enzymes,
Surfactants, alkali agents, alkali impact agents, chelating agents, extenders, bleach activators, powder fluidity improvers, and the like.

For the purpose of further improving the detergency as a detergent, an enzyme (d component) such as amylase, protease, lipase, pullulanase and the like is preferably blended. More specific examples of preferred enzymes include termamyl, maxacar, savinase, and the like. From the viewpoint of the stability of the detergent composition, duramil (a registered trademark of Novo, Inc.)
And Durazyme (Novo Corporation, registered trademark) are most preferred, and it is most preferred to use them alone or as a mixture. If the amount of the enzyme is too large, there is an economic disadvantage due to an increase in cost.
Most preferably, it is blended in the range of When the detergent composition contains an enzyme, the peroxygen compound and the enzyme are present in the form of granules and present in the detergent and the granules of the components excluding the components excluding the peroxygen compound and the enzyme from the detergent components. To do it.

As a property required for a nonionic surfactant used for a granular detergent for an automatic dishwasher, it is important to have a low foaming property in addition to having a cleaning action. It is also possible to suppress foaming by using an antifoaming agent in combination. It is more advantageous in terms of cost that the surfactant has low foam. If it is evaluated from the point of pursuing low foaming property, specifically, it is characterized in that an alkyl group having 8 to 18 carbon atoms is contained in a hydrophobic group, and a copolymer of an oxyethylene group and an oxypropylene group is contained in a hydrophilic group. Non-foaming nonionic surfactant to be, or a mixed nonionic surfactant containing the nonionic surfactant as an essential component,
Particularly preferred. Among them, nonionic surfactants represented by the following general formulas (1) and (2) give good results. _{R 1 O (EO) n (} PO) mR 2 (1) R 1 O (EO) l (PO) kH (2) (R 1 is a linear or branched alkyl group having 8 to 18 carbon atoms, an alkenyl group Or an alkylphenyl group, R
₂ represents a linear or branched alkyl group or alkylphenyl group having 1 to 8 carbon atoms, EO represents ethylene oxide, and PO represents propylene oxide. n is 0 to 4
0, preferably 3 to 20, m is 1 to 20, preferably 5
-15, l is 0-40, preferably 3-20, k is
Represents a number from 1 to 20, preferably from 5 to 15. EO, P
When O is added, random addition or block addition may be performed. Examples of these compounds are as follows: Sophthanol EP series (registered trademark of Nippon Shokubai Chemical Industry Co., Ltd.), pull lafax series (registered trademark of BASF), Rheox, Leocon, Lionol series (Lion Corporation) Registered trademark) and the like, but are not limited thereto. The amount of the nonionic surfactant is not particularly limited, either, but is 1 to 10% by weight, preferably 1 to 5% by weight, based on the whole composition. If the amount is less than 1% by weight, the detergency against oil stains may be too low. Conversely, if it is more than 10% by weight,
The absorbency of the detergent itself may increase beyond the effects of the present invention.

As the alkali agent, sodium carbonate or the like can be preferably used, and these may be powder or granules. When these alkaline agents are used in detergents for automatic dishwashers, they are generally blended in the range of 5 to 50% by weight, and if the amount is too small, the washing power is reduced. On the other hand, if the enzyme and the bleaching agent are used together, the activity of these components may not be fully functioned even if the amount is too large.

The alkali impact agent is compounded in order to enhance the effect of the enzyme and the bleaching agent, and to adjust the pH of the aqueous detergent solution at the time of washing to be within the optimum range of 8.5 to 10.5. And sodium bicarbonate and the like are very suitable. Since the compounding amount of the alkali impact agent is compounded for adjusting the pH of the detergent aqueous solution at the time of washing as described above, the compounding amount varies depending on the compounding amount of the alkaline agent. %.

[0013] Detergents for automatic dishwashers are used for the purpose of enhancing the detergency and suppressing water spots generated by the precipitation of water-insoluble alkaline earth metal salts on the glass surface.
Chelating agents are commonly included. Specifically, low molecular weight carboxylic acid chelating agents such as succinate and citrate,
Polymeric polycarboxylic acid-based chelating agents such as polyacrylates and polyacrylic / polymaleic acid copolymers are preferred. The amount of the chelating agent varies depending on its type and performance, but is generally 5 to 25% by weight in the case of a low-molecular-weight carboxylic acid-based chelating agent, and 0% by weight in the case of a high-molecular-weight polycarboxylic acid-based chelating agent. It is preferable that the compounding amount be from 0.5 to 10% by weight. If the amount is less than this range, the chelating ability is insufficient, so that a water spot is generated or a sufficient detergency cannot be obtained. If the amount is too large, further improvement in performance is not recognized, but on the other hand, there is often an economic disadvantage such as an increase in cost.

In formulating as a granular detergent, it is also preferable to incorporate an inorganic powder such as sodium sulfate as a bulking agent. Needless to say, since the preferable compounding amount of the extender is determined by the balance with other components, there is no particularly preferable compounding amount, but if the amount of the active ingredient is too small, the performance such as detergency may be insufficient. Because there is
A range of 0 to 50% by weight is common.

It is also very preferable to add a bleaching activator, such as an organic peracid precursor or a metal complex, which further improves the performance of the peroxygen compound.

In addition to a powder fluidity improver such as amorphous silica, the detergent for an automatic dishwasher of the present invention requires various additives such as additives such as pigments. Accordingly, it is possible to appropriately mix them within a range not to impair the effects of the present invention.

The detergent composition of the present invention comprises adding a perfume to detergent base particles composed of components other than sodium aluminate and granular peroxygen compound, coating the surface with sodium aluminate, and further removing the peroxygen compound. It is most preferred to produce by mixing solids. However, it is not limited to this method.

In preparing the detergent composition for an automatic dishwasher according to the present invention, a surfactant, an alkali agent, an alkali impact agent and the like, which are optional components of the detergent composition, have a uniform composition. Stir and mix until well. Their average particle size is about 1.0 to 0.1 mm. The aggregate of this particle size constitutes the base of the detergent. The perfume is sprayed on the base of the detergent. The fragrance was diluted with a solvent. Alcohol or the like can be used as the solvent. Next, an alkaline silicate and sodium aluminate are added. Then, stirring and mixing are further repeated so that the particles adhere to the surface of the base particles of the detergent.

Next, optional enzymes and peroxygen compounds are added and mixed. The finally obtained detergent for automatic dishwashers has an average particle size of 0.1 to 2.0 mm and a bulk density of 0.8 to 1.2 g / ml. The apparatus used for the production is not particularly limited by its structure or function, but examples of the apparatus which are the most inexpensive and have high effects include a ribbon mixer, a V-type mixer, and a double cone type mixer. Above all, a ribbon mixer is very suitable in consideration of its easy handling, low cost equipment, easy metering and the like.

Next, the present invention will be described in more detail by way of examples, but the present invention is not limited to these examples.

The following three kinds of fragrances were used in the present invention. Perfume A: limonene Perfume B: limonene: pinene: linalool: ambroxane: DPG = 70: 10: 5: 5: 10 Perfume C: Mixed perfume shown in Table 1 below
