Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a granular nonionic detergent composition containing a nonionic surfactant as a main component, which is excellent in detergency, particularly detergency against polyester at low temperature.

[0002]

2. Description of the Related Art Nonionic surfactants generally have a low foaming property, their detergency is hardly affected by the hardness of water, and they are particularly excellent in dirt dispersibility and stain dispersibility at low temperatures. Furthermore, nonionic surfactants are known to be excellent surfactants because they have good biodegradability, have a low environmental load, have low toxicity, and have no safety problems. However, the nonionic surfactant, like the anionic surfactant, has a problem that the surface activity is lowered at a low temperature and the detergency at low temperature, particularly the detergency for polyester is lowered. By the way, JP-A-4-89899 uses a specific granular sodium silicate and sodium carbonate, and JP-A-4-306300 uses a crystalline aluminosilicate, a reducing agent and an enzyme. JP-A-4-3398
No. 98 discloses the use of an amorphous oil absorbing carrier, crystalline aluminosilicate and sodium carbonate.
JP-A-363400 describes the use of amorphous aluminosilicate and sodium carbonate. However, none of these techniques was able to sufficiently improve the detergency of polyester at low temperatures.

[0003]

SUMMARY OF THE INVENTION Accordingly, the object of the present invention is to provide a granular nonionic detergent composition containing a nonionic surfactant as a main component, which is excellent in detergency, particularly detergency against polyester at low temperature. And

[0004]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to achieve the above object, and as a result, by using an aluminosilicate having a crystallinity of 20 to 80% in combination with a nonionic surfactant. The inventors have found that the detergency of polyester at low temperatures can be solved, and have reached the present invention. Specifically, among various cleaning builders, aluminosilicate, in particular, is affected by external factors such as temperature and electrolyte, and the actual cation exchange capacity is lower than the theoretical value. It is known to deteriorate. By the way, aluminosilicates include crystalline ones and amorphous ones. A crystalline substance has a high cation exchange capacity, but has a low adsorption force, and is therefore easily affected by external factors. On the other hand, the amorphous one has a high adsorption power, but the cation exchange capacity is lower than that of the crystalline one, so that it is less effective for the low temperature detergency. In Japanese Patent Laid-Open No. 4-363400, in order to make up for the drawbacks of both of them, a device of mixing a crystalline substance and an amorphous substance is used, but when actually washed, the crystalline substance is crystalline. Only an intermediate effect between the single substance and the amorphous substance was exhibited. It is considered that this is because the crystalline material and the amorphous material are simply powder-mixed and exist discontinuously.

Therefore, the inventor of the present invention considered not to make up for the defects of both the crystalline and amorphous ones, but to utilize the features of both. That is, instead of simply mixing powders of a crystalline material and an amorphous material, one having a single structure in which a crystalline portion and an amorphous portion coexist is produced from the synthesis stage. It has been found that the use of the above can exert a higher detergency than the use of the crystalline substance alone, the amorphous substance alone, or the mixture thereof. That is,
The present invention has a nonionic surfactant and a crystallinity of 20-8.
It relates to a granular nonionic detergent composition, characterized in that it contains 0% aluminosilicate. The crystallinity of aluminosilicate used in the field of detergents is almost 100%.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. In the present invention, the nonionic surfactant is not particularly limited, and various nonionic surfactants can be used. Examples of preferable nonionic surfactants include the following. (1) C3-C22, preferably C8-C18 aliphatic alcohol with C2-C4 alkylene oxide on average 3
Polyoxyalkylene alkyl (or alkenyl) ether added to ３０30 mol, preferably 7-20 mol. Among these, polyoxyethylene alkyl (or alkenyl) ether and polyoxyethylene polyoxypropylene alkyl (or alkenyl) ether are preferable. (2) polyoxyethylene alkyl (or alkenyl)
Phenyl ether. (3) A fatty acid alkyl ester alkoxylate represented by the following formula in which an alkylene oxide is added between ester bonds of a long-chain fatty acid alkyl ester. R ¹ CO (OA) _n OR ² (R ¹ CO represents a fatty acid residue having 6 to 22 carbon atoms, preferably 8 to 18 carbon atoms. OA represents 2 to 4 carbon atoms such as ethylene oxide and propylene oxide, preferably 2 to 3 represents an addition unit of alkylene oxide, n represents the average number of moles of alkylene oxide added, and generally 3 to 3
It is a number of 0, preferably 7 to 20. R ² has 1 carbon atom
Represents a lower alkyl group optionally having 3 to 3 substituents. (4) Polyoxyethylene sorbitan fatty acid ester. (5) Polyoxyethylene sorbite fatty acid ester. (6) Polyoxyethylene fatty acid esters. (7) Polyoxyethylene hydrogenated castor oil. (8) Glycerin fatty acid ester.

Among the above nonionic surfactants, polyoxyethylene alkyl (or alkenyl) ethers having a melting point of 40 ° C. or less and an HLB of 9 to 16 and fatty acid methyl ester ethoxylates obtained by adding ethylene oxide to fatty acid methyl ester are particularly preferable. Used. Further, these nonionic surfactants may be used as a mixture. The nonionic surfactant is preferably contained in the granular nonionic detergent composition in an amount of 15 to 50% by weight, more preferably 15% by weight.
-40% by weight, particularly preferably 15-35% by weight. If this amount is less than 15% by weight, not only the concentration of the nonionic surfactant in the obtained detergent particles is low but also the bulk density is low, so that a good detergent effect cannot be obtained unless the amount of the detergent used is increased. This is not preferable because it results in a conflict with compactness. It is also not preferable in terms of resource saving.
On the other hand, if it exceeds 50% by weight, it is difficult to suppress the exudation, which is not preferable. The aluminosilicate used in the present invention itself has a monolithic structure in which a crystalline part and an amorphous part coexist, and a crystalline aluminosilicate and an amorphous aluminosilicate are used. Is not just a mixture of. As the aluminosilicate used in the present invention, an aluminosilicate having a crystallinity of 20 to 80%, that is,
A monolithic structure having a ratio of a crystalline portion to an amorphous portion of 2/8 to 8/2 is used. Crystallinity is measured by powder X-ray diffraction analysis. In this case, generally, the diffraction line due to the crystal has a sharp peak, and the scattering due to the amorphous becomes a very broad halo. When unbound and crystalline are mixed, the ratio of crystalline to the entire sample is called crystallinity. 12 to 1 for aluminosilicate
It can be obtained from any of the following formulas from the scattering intensity of the main peak detected at 3Å, that is, the peak that is an index of crystallinity.

Crystallinity (%) = {1- (scattering intensity of amorphous part of sample / 100% amorphous clay)} × 100 or crystallinity (%) = {crystalline part of sample Scattering intensity / 10
0% crystalline clay} × 100 This crystallinity can be freely controlled by the synthesis conditions, and the crystallinity can be set according to the purpose of use. When the detergency is targeted as in the present invention, the crystallinity is 20 to 80%, preferably 30 to 70%.
%, And more preferably 40 to 60%. Also, when importance is attached to storage stability, the crystallinity is preferably 20.
-60%, and more preferably 20-50%. If the crystallinity is lower than 20% or higher than 80%, the object of the present invention cannot be achieved. Heretofore, in the field of detergents, aluminosilicates having a crystallinity of usually 100% have been used. The coexistence of a crystalline part and an amorphous part in a single object can be easily judged from the X-ray diffraction pattern. It also shows a different diffraction pattern than the mere mixture.

As the method for producing the aluminosilicate used in the present invention, the following two methods, a crystallization method and a melting method, can be exemplified. In the crystallization method, an alumino raw material such as an aqueous solution of sodium aluminate and a silicic acid raw material such as water glass are reacted while being heated to about 100 ° C., the product is filtered, washed, and then dried at about 100 ° C. Then 50
After firing at 0 to 1000 ° C., by pulverizing,
The aluminosilicate used in the present invention is obtained. On the other hand, in the melting method, an alumino raw material such as alumina, a silicic acid raw material such as silica, and an alkali are added in an amount of 2000 to 300.
The aluminosilicate used in the present invention can be obtained by mixing while melting at 0 ° C., then rapidly cooling to 30 ° C. or lower, and crushing the produced mass. As a method for controlling the crystallinity of the aluminosilicate, the crystallization method can be used to control the firing temperature, and the melting method can be used to control the quenching temperature and speed. The aluminosilicate of the present invention is preferably 5 to 60% by weight, more preferably 10 to 60% by weight, particularly preferably 15 to 6% by weight in the granular nonionic detergent composition.
It is contained at 0% by weight. If this amount is less than 5% by weight, the fluidity and caking resistance of the resulting detergent particles are likely to deteriorate. On the other hand, if it exceeds 60% by weight, the fine powder of the obtained detergent particles increases and the dust becomes worse, which is not preferable.

In the granular nonionic detergent composition of the present invention,
Generally, various optional components used in detergents can be blended without particular limitation. Such optional components include
For example, the following components are included. There are various methods for blending these components. For example, these components may be blended in the granulation treatment step, or may be mixed with the detergent particles obtained by the granulation treatment. (1) As an inorganic cleaning builder, sodium carbonate, potassium carbonate, sodium silicate, potassium silicate, sodium tripolyphosphate, sodium pyrophosphate, etc. (2) As organic washing builders, citrate, succinate, polyacrylate, polyacrylic acid-maleic acid copolymer, EDTA and the like. (3) Bis (triazinylamino) stilbene disulfonic acid derivatives, bis (sulfostyryl) biphenyl salts [Tinopearl CBS], etc. as fluorescent agents. (4) As the enzyme, lipase, protease, cellulase, amylase and the like. (5) As a bleaching agent, percarbonate, perborate and the like. (6) Cationic surfactants such as dialkyl-type quaternary ammonium salts as antistatic agents. (7) As surface modifiers, fine calcium carbonate, fine zeolite, polyethylene glycol and the like. (8) As the anionic surfactant, α-sulfo fatty acid methyl ester salt, linear alkylbenzene sulfonate,
α-olefin sulfonate, alkyl sulfate, fatty acid soap and the like. (9) Cellulose derivatives such as carboxymethyl cellulose, polyethylene glycol and the like as anti-redeposition agents. (10) As a bulking agent, sodium sulfate, potassium sulfate, sodium chloride and the like. (11) As a reducing agent, sodium sulfite, potassium sulfite and the like.

Next, as a preferred method for producing the granular nonionic detergent composition of the present invention, there are the following methods. The granular nonionic detergent composition of the present invention is a kneading extruder, preferably a kneader, while introducing a nonionic surfactant, an aluminosilicate, and optionally other optional components, while applying shearing force in the kneader. It can be produced by mixing to form a granulated product (solid detergent), then crushing and granulating with a crushing granulator, preferably a cutter mill, and performing a consolidation treatment. The granular nonionic detergent composition of the present invention can also be produced by a stirring granulation method. In the stirring granulation method, as a stirring granulator, a nonionic surfactant and an aluminosilicate are further added to an internal stirring type granulator such as a high speed mixer, a sugi mixer, and a Loedige mixer. The granular nonionic detergent composition of the present invention can be produced by introducing a component capable of being treated and granulating. Furthermore, the detergent particles thus produced may be coated with a coating agent in a rolling drum, for example.

Further, the detergent particles thus produced may be post-added with enzymes, perfumes and the like. The obtained granular nonionic detergent composition of the present invention has an average particle size of 3
00-3000 μm, preferably 350-2000 μm
