Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet cleaner composition whose dissolution rate is less affected by water temperature and less likely to swell, and a manufacturing method thereof which can be molded by press molding.

[0002]

2. Description of the Related Art Conventionally, polyethylene glycol, which has been used as a cleaning composition that can be put into a low tank of a flush toilet,
Nonionic surfactant such as ethylene oxide, propylene oxide copolymer or its derivative, glycerin fatty acid ester, sorbitan fatty acid ester, etc. as the main agent, anion surfactant such as alkylbenzene sulfonate, etc. as the main agent Is commercially available.

However, these materials have problems that they absorb water and swell to a large extent, and that the rate of dissolution changes depending on the water temperature. If it greatly swells in water, it will cause a problem by blocking the drainage port of the low tank of the toilet, and if the melting speed differs depending on the water temperature, the number of times it can be used in summer and winter is different and the color appearance is not stable. An unfavorable surface is generated in terms of quality.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention
Toilet cleaner composition that improves the difference in dissolution between cold water (winter) and hot water (summer), is hardly affected by water temperature, dissolves at a substantially constant rate throughout the year, and does not significantly swell in water, and a method for producing the same Is to provide.

[0005]

[Means for Solving the Problems] Therefore, the surface of the drug is gradually disintegrated by the water flow caused by the discharge / inflow of water in the tank of the toilet, and a substantially constant drug is always released / dispersed in water regardless of the water temperature. Designed to be. That is, a method was developed in which the drug is gradually swollen from the surface without being swollen in water and dissolved in water.

In designing such a composition, when a fatty acid alkanolamide, an anionic surfactant, a nonionic surfactant that forms a gel in water, and a water-soluble inorganic or organic filler are blended and molded. It has been found that the above problems can be solved.

As a result of extensive studies, a fatty acid alkanolamide, which is a component which is slightly dissolved in water and does not swell at all, was used as a main component. This fatty acid alkanolamide has a property of being slightly soluble in water by itself and hardly soluble in cold water in particular, so that it is preferably used in a sufficiently fine powder state.

The amount of the fatty acid alkanolamide compounded is preferably about 10 to about 50% by weight. If it is less than about 10%, the solubility of the drug in water may be too fast or it may disintegrate. If it exceeds about 50% by weight,
A problem occurs that the solubility of the drug in water decreases.

The drug released in water is preferably dispersed as finely as possible. This is because it dissolves in water more quickly. Also, should an anionic surfactant, a nonionic surfactant that forms a gel in water, and a water-soluble inorganic or organic filler be blended in the form of fine powder that is particularly sufficiently fine to improve the solubility? Alternatively, it is preferable to heat-melt and uniformly mix with other components.

In order to show good dispersion and solubility in warm water (about 25 ° C), when anionic surfactant alone is added to fatty acid alkanolamide, it hardly dissolves in cold water (about 5 ° C), or Significant collapse and cracks were observed. That is, when the amount of the anionic surfactant added was less than about 5% by weight, the anionic surfactant was hardly dispersed and dissolved, and conversely, when the amount added was more than about 20% by weight, significant disintegration and cracking occurred.

Therefore, a water-soluble inorganic or organic filler is blended together with a nonionic surfactant that forms a gel in water, and the drug gradually disintegrates from the surface even in cold water.
It was dispersed and immediately dissolved in water. In particular, it is considered that the nonionic surfactant that forms a gel in water prevents the drug from collapsing at once, especially in cold water, and plays a role as a binder.

The amount of the nonionic surfactant which forms a gel in water is preferably about 1 to about 10% by weight. If it is less than about 1% by weight, there is a problem that gel formation in water is insufficient, and if it exceeds about 10% by weight, solubility in water increases and the drug disappears quickly or disintegrates suddenly. There is a problem that

The blending amount of the water-soluble inorganic or organic filler is preferably about 5 to about 70% by weight. About 5
If the amount is less than 10% by weight, it becomes difficult to maintain appropriate solubility in water and the difference in solubility between cold water and hot water cannot be eliminated, and if it exceeds 70% by weight, disintegration phenomenon occurs. This causes a problem that the solubility in water cannot be controlled.

The mechanism by which the drug gradually disintegrates is presumed to be as follows. First, components such as an anionic surfactant, an inorganic filler and an organic filler, which are present on the surface of the drug and have a relatively high dissolution rate, are eluted. Next, a nonionic surfactant that forms a gel in water, which has a slightly slower dissolution rate, swells on the surface and forms a gel layer. Among them, fatty acid alkanolamide (fine particles) that has the slowest dissolution rate is present. Exists. When a water flow occurs in this state, only the surface layer collapses and is dispersed / dissolved in water.

That is, since the slightly swollen nonionic surfactant forms a gel layer on the surface of the drug, and the fatty acid alkanolamide which is almost insoluble in water is dispersed therein, water permeates more than necessary into the drug. It seems that it is preventing you from doing.

When each component is dispersed in the drug in the form of fine particles or in a molten state, there are components that are melted by heat and components that are not melted by heat. When raw materials are supplied in powder form and kneaded without being melted so much, part of them is melted by heat generated by physical action such as kneading and friction in the manufacturing stage, and the surface of other components is coated. It seems that there is. From the beginning, components that melt with heat (100 ° C
When a component which becomes liquid at the temperature below is used by melting, the surface of the component such as an inorganic salt which is insoluble in the liquid component when heated (100 ° C. or lower) is coated. These melted components or components such as perfume added as a liquid from the beginning dissolve other components and act as a binder, affecting the dissolution rate of the drug. The dissolution rate of the drug is controlled by the particle size of each component, the blending amount, the degree of kneading (melting degree) with a machine, and the degree of compression. (Fatty acid alkanolamide) As the fatty acid alkanolamide, for example, one obtained by reacting at least one fatty acid having 4 to 22 carbon atoms with an alkanolamine composed of at least one alkanol having 2 to 6 carbon atoms is used. be able to. These have the advantages that they are easily available as raw materials and have cleaning power.

The fatty acid used to produce the fatty acid alkanolamide may be a single fatty acid such as lauric acid or myristic acid, or a natural fatty acid such as coconut oil fatty acid, palm fatty acid, beef fatty acid. Or a synthetic fatty acid.

Among these, as raw materials that are easily available, inexpensive and easy to use, for example, coconut oil fatty acid monoethanolamide, coconut oil fatty acid diethanolamide, coconut oil fatty acid monopropanolamide, coconut oil fatty acid dipropanolamide , Palm oil fatty acid monoethanolamide, palm oil fatty acid diethanolamide, palm oil fatty acid monopropanolamide, palm oil fatty acid dipropanolamide, beef oil fatty acid monoethanolamide,
Examples thereof include beef oil fatty acid diethanolamide, beef oil fatty acid monopropanolamide, and beef oil fatty acid dipropanolamide, but are not limited thereto.

Among them, coconut oil fatty acid monoethanolamide is advantageous in that the raw material is easily available, the cost is low, and the solid is easy to handle at room temperature.

The fatty acid alkanolamide has an average particle size (meaning 50% particle size on a mass basis) of 500 μm.
It is desirable to supply the following fine powder, preferably in a state of 300 μm or less, in order to improve solubility and dispersibility. (Anionic surfactant) As the anionic surfactant, for example, sulfonate type, sulfate type, ether sulfate type, ether carboxylic acid type, phosphate type,
Anionic surfactants such as sulfosuccinate type and taurate type can be used. These have the advantage that these anionic surfactants themselves are readily soluble in water, and therefore fatty acid amides, which are relatively insoluble in water, can be easily dissolved.

In particular, prim-alkane sulfonate having 8 to 20 carbon atoms, sec-alkane sulfonate, alkylaryl sulfonate, α-olefin sulfonate,
Alkylsulfate sodium salt, calcium salt,
And magnesium salts are preferred. Since these are general-purpose products, they are easily available, and have the advantages of excellent cleaning power and low cost.

Further, any form of powder, paste or liquid can be used, but it is preferable to supply in the form of powder in terms of easiness of mixing with other components. To disperse a fixed amount of fatty acid alkanolamide,
A small amount can be used if a fine-grained one is used. Since a large amount is required when a coarse particle size is used, the particle size and amount of the anionic surfactant used are adjusted according to the particle size of the fatty acid alkanolamide.

It is considered that the influence of the particle size of the anionic surfactant is reduced when the mixture is used under melting together with the component which is melted by heat (100 ° C. or less). (Nonionic Surfactant Forming Gel in Water) Any nonionic surfactant that forms a gel in water can be used, but among them, the following nonionic surfactants are particularly preferable. Nonionic surfactant is fine powder or heat (1
It is desirable to use it by mixing it with a component that melts at 00 ° C. or less) under melting. Higher Alcohol Ethylene Oxide Adduct A higher alcohol having 6 to 20 carbon atoms and an ethylene oxide addition mole number of 5 to 100 forms an appropriate gel in water and has appropriate solubility in water. It is preferable in some respects. It is preferably solid at room temperature, but liquid can be used.

Alkanol (C8-18) ethylene oxide (5-100 mol) adduct, alkylphenol (C7-20) ethylene oxide (5-20).
100 mol) adduct and the like are preferable.

Examples of fine powders that can be pulverized include coconut oil alcohol with 50 mol of ethylene oxide, hardened tallow alcohol with 50 mol of ethylene oxide, and nonylphenol with 50 mol of ethylene oxide. As the liquid at room temperature, 8 mol of ethylene oxide adduct of coconut oil alcohol, 10 mol of ethylene oxide adduct of nonylphenol, and the like can be used, but not limited thereto.

The higher alcohol ethylene oxide adduct is preferably used as a fine powder or mixed with a component which is melted by heat (100 ° C. or less) under melting. Polyethylene glycol and its derivatives Polyethylene glycol and its derivatives have a molecular weight of 1
Any one of 000 to 30,000 can be used. If the molecular weight is less than 1000, the solubility in water tends to be remarkably accelerated, and if it exceeds 30,000, the swelling property tends to be remarkable, and it tends to be difficult to use.

As the derivative, one obtained by blocking one or both ends of the hydroxyl group at the terminal with an alkyl group, an alkylaryl group, an acyl group or the like can be used. For example, polyethylene glycol diester, polyethylene glycol diether and the like can be used.

Polyethylene glycol and its derivatives are preferably used as a fine powder or as a mixture with a component which is melted by heat (100 ° C. or less) under melting. Polypropylene glycol and its derivatives Polypropylene glycol and its derivatives have a molecular weight of 1
Those of 000 to 30,000 can be preferably used. When the molecular weight is less than 1000, the solubility in water tends to be remarkably accelerated, and when it exceeds 30,000, the swelling property tends to be remarkable, so that it tends to be difficult to use.

As the derivative, one obtained by blocking one or both ends of the hydroxyl group at the terminal with an alkyl group, an alkylaryl group, an acyl group or the like can be used.

Polypropylene glycol and its derivatives are preferably used as a fine powder or as a mixture with a component which is melted by heat (100 ° C. or less) under melting. Ethylene Oxide / Propylene Oxide Copolymer Ethylene oxide and propylene oxide may be either random polymerization or block polymerization, and the molecular weight thereof is preferably 1,000 to 30,000. When the molecular weight is less than 1000, the solubility in water tends to be remarkably accelerated, and when it exceeds 30,000, the swelling property tends to be remarkable, so that it tends to be difficult to use.

The solubility in water can be appropriately changed by the degree of polymerization of ethylene oxide and propylene oxide and the ratio of ethylene oxide / propylene oxide.

The ethylene oxide / propylene oxide copolymer is preferably used as a fine powder or as a mixture with a component which is melted by heat (100 ° C. or less) under melting. Other polyalkylene glycols or derivatives thereof Polymers of alkylene oxides having 4 or more carbon atoms, copolymers of these with ethylene oxide or propylene oxide, and the like can also be used. Further, those obtained by reacting various compounds with terminal hydroxyl groups of these substances can also be used.

In general, the hydroxyl group at the terminal of polyalkylene glycol is highly reactive, so that it can easily form an ether bond, an ester bond, or a urethane bond with various compounds. For example, Japanese Patent Publication No. 5-38039, Japanese Patent Publication No. 5-38039
No. 430, Japanese Patent Publication No. 58-33916, JP-A-5-59.
The compounds described in, for example, No. 398 can be used.
In addition, compounds such as polyalkylene polyamine and tetronic type can also be used. However, in both cases, the swelling property becomes remarkable as the molecular weight increases, so that the molecular weight is preferably 30,000 or less.

The other polyalkylene glycol or its derivative is preferably used in the form of fine powder or a component which is melted by heat (100 ° C. or lower) and mixed under melting. (Water-soluble inorganic filler) The water-soluble inorganic filler is blended for the purpose of adjusting the dissolution rate of the composition, in addition to being blended as a cleaning aid. Specific examples include carbonates, sulfates, hydrochlorides, phosphates, borates, and boric acids of alkali metals and alkaline earth metals.

For example, comparison of sodium sulfate, magnesium sulfate, sodium chloride, magnesium chloride, sodium carbonate, sodium hydrogen carbonate, sodium phosphate, sodium monohydrogen phosphate, sodium dihydrogen phosphate, sodium tripolyphosphate, sodium pyrophosphate, etc. Examples include those that are easily soluble in water to those that are relatively insoluble in water, such as borax, boric acid, magnesium carbonate, calcium carbonate, and calcium sulfate.

Generally, when a large amount of a highly soluble drug is mixed in the drug, the drug dissolution rate is increased, but this is not always the case in the disintegrated drug. For example, when borax, which is a fine powder having a relatively low solubility, is blended in the drug, it promotes disintegration and rather accelerates the dissolution rate. The dissolution rate of the drug depends not only on the solubility of the inorganic filler, but also on its particle size, blending amount, kneading condition (molten state of a substance that melts by heat), compressibility and the like.

This applies not only to the inorganic filler but also to other raw materials. (Water-Soluble Organic Filler) A water-soluble organic filler can also be added for the purpose of adjusting the dissolution rate of the composition, in addition to being added as a cleaning aid. Specifically, the carbon number is 2
Examples thereof include carboxylic acids, hydroxycarboxylic acids, polycarboxylic acids or hydroxypolycarboxylic acids or salts thereof, aminocarboxylic acids, polyaminocarboxylic acids or salts thereof of 10 to 10.

For example, citric acid, malic acid, succinic acid,
Examples thereof include organic acids such as maleic acid, fumaric acid, gluconic acid and adipic acid, and salts thereof, aminopolycarboxylic acids such as ethylenediaminetetraacetic acid and nitrilotriacetic acid, and salts thereof. In addition, glucose, sucrose, fructose,
Examples include sugars such as lactose and urea.

Similar to the inorganic filler, the dissolution rate of the drug depends not only on the solubility of the organic filler but also on its particle size, blending amount, kneading condition (molten state of a substance that melts by heat), compressibility and the like. There is. (Water-soluble or water-dispersible pressure-sensitive adhesive) It is not always necessary to mix a water-soluble or water-dispersible pressure-sensitive adhesive, but by adding about 0.01 to about 5% by weight of this component,
It is possible to improve the adhesive force of the drug to the bottom of the tank,
It is possible to prevent the drug from easily moving in the tank even if some water flow occurs.

Specific examples include methyl cellulose, hydroxymethyl cellulose, carboxymethyl cellulose, carboxymethyl starch, pregelatinized starch, guar gum, locust bean gum, xanthan gum, sodium alginate, sodium polyacrylate, polyvinyl alcohol, polyvinylpyrrolidone, and gum arabic. Various natural and synthetic polymer compounds can be used. (Water-soluble paint) Water-soluble paint is not an essential component, but in order to give a suitable color to the flowing water and to refresh the toilet,
It is preferable to blend from about 0.01 to about 20% by weight.
It is preferable that the pottery has no dyeing property, has some light resistance, and is safe.

Further, if the chlorine resistance is too excellent, it is not preferable because it is less likely to be discolored when released into the environment. Note that, for example, blue or the like is preferably used. (Fragrance) Although fragrance is not an essential component, it has the function of a binder that dissolves a surfactant in the drug and hardens the drug, in addition to blending for the purpose of leaving a refreshing scent in the toilet after washing, It is preferable to add 0.01 to about 15% by weight.

Further, the hardness of the drug can be adjusted by the amount of the fragrance, and the dissolution rate of the drug can be controlled by the kind and blending amount of the fragrance. (Manufacturing method) It can be manufactured by tableting, melting, extrusion (kneading) or press molding.

For example, in extrusion molding, raw materials are used in the form of fine powder (the liquid component is melted and agitated with other solid components, solidified, and then finely powdered for use), such as Nauta mixer, V-shaped mixer, ribbon mixer, etc. After being supplied to a mixer and dry-blended, the mixture is introduced into a kneader such as an extruder or a continuous kneader and stirred and mixed with a liquid component to form a dough. At this time, since the raw materials are sufficiently mixed in advance, there is no need for excessive stirring and kneading. After that, the dough is introduced into a molding machine such as an extrusion granulator and compression molded into an arbitrary shape.

In the case of such a manufacturing facility, frictional heat may be generated by mechanical stirring and kneading, so be careful not to put the raw materials in an excessively molten state. In some cases, stirring and kneading while cooling. , Molding.

In the kneading method, a large amount of energy is required for solidifying when the whole is in a molten state, and the production efficiency is lowered. By supplying the raw materials in the form of fine powder and thoroughly mixing them in a dry state in advance, it is possible to quickly perform molding with a uniform composition without melting the whole and without spending energy.

Although a large amount of energy is required, heat (1
There is also a method in which a component that melts at 00 ° C. or less) and a component that does not melt are separately introduced into an extruder and stirred and kneaded while cooling to form a dough.
By adopting this method, it is possible to prepare a drug having a more uniform composition.

In the melting method, fatty acid alkanolamides,
A component such as a nonionic surfactant that is melted by heat (100 ° C. or lower) is melted by heating and uniformly stirred, and then a powder raw material is charged under stirring to uniformly disperse the raw material. Then, the mixture is cooled to near the freezing point, the fragrance is added, and the mixture is stirred uniformly and then poured into a mold to be cooled and solidified.
