Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a granular detergent that is highly soluble in water and has high detergency. ′ Traditionally, commercially available powder or granular cleaning agents reportedly contain
Surface-active rigid materials such as sodium alkylbenzene sulfonate,
There are some builders such as mirabilite, sodium tripolyphosphate, soda carbonate, and sodium metasilicate that contain a small amount of water, about 6S to 7θ%, in addition to 20%, but in many cases, the small amount is added to a large amount of water. However, depending on the purpose and place of use, solid detergents that dissolve easily just by putting them in water without stirring or other operations may be convenient and portable. , is requested.

In view of the above, the inventors conducted various studies on granular detergents with excellent solubility and detergency, and as a result, they arrived at the present invention.

The present invention combines an inorganic builder selected from phosphates, carbonates, and sulfates with alkylarylsulfonic acid, allylsulfo/acid,
A cleaning agent made by adding a glycol or alcohol solvent to one or more organic builders selected from ethylenediaminetetraacetic acid and alkali metal salts of lower fatty acids and granulating them.
It has excellent solubility and dispersibility, great cleaning power, and drains quickly.

To explain the example below, the inorganic builder includes:
Monobasic potassium phosphate, dibasic potassium phosphate, tertiary potassium phosphate, potassium birophosphate, monobasic sodium phosphate, dibasic sodium phosphate,
No. 39: Phosphates such as sodium acid and sodium birophosphate, carbonates such as potassium carbonate and sodium carbonate, magnesium sulfate and other highly soluble sulfates, which can be used singly or in combination.
Those that can be used in combination of more than one species and are relatively soluble are preferred.

Organic builders include sodium alkylbenzenesulfonate, sodium alkylnaphthalenesulfonate and other sodium salts of alkylarylsulfonic acids, sodium benzenesulfonate, sodium toluenesulfonate and other sodium salts of allylsulfonic acids, and sodium salts of ethylenediaminetetraacetic acid. , alkali metal salts of 02-C9 saturated fatty acids, etc., and these may be used singly or in combination.
Used as a mixture of more than one species.

In addition, the above-mentioned solvents not only facilitate the dissolution and removal of oil films adhering to dust etc., but also act to promote the granulation of powder materials such as the above-mentioned builders. , ethyl cellosolve, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, etc., and alcoholic solvents such as isopropyl alcohol, isobutyl alcohol, etc.

The blending proportions of the above inorganic builder, organic builder and solvent can be adjusted as appropriate, but include 70 to 30 parts of inorganic builder (the same applies below parts by weight), 5 to /S parts of organic builder, and j to /θ of solvent.
In many cases, it is preferable to reduce the amount to about 30%.

In addition to the builders mentioned above, suitable inorganic or organic builders can also be added to the formulations, and suitable amounts of suitable surfactants can also be added, which may improve the cleaning effect.

Luni, which manufactures granular cleaning agents using the above compounded materials, first mixes the respective required amounts of inorganic builder and organic builder to form a uniform powder, and then stirs and mixes the powder to make it fluid. A predetermined amount of solvent is gradually added dropwise so as not to lose properties, and the mixture is granulated to form granules with good fluidity. Since some of the builders mentioned above have relatively high hygroscopicity, it is desirable to determine the blending in advance experimentally. The obtained granular cleaning agent has relatively high hygroscopicity, so it is placed in a container such as a bag made of a material with a barrier property laminated with aluminum foil, etc., and the amount dissolved in one batch is sealed and sold on the market. An example of the blending of raw materials for the cleaning agent of the present invention is shown below.The results of testing the dissolution state of the cleaning agent of the present invention and commercially available granular or powdered household cleaning agents were as follows. . The test method is to prepare a beaker containing λθθω of water at room temperature, add 2g of each sample cleaning agent from above, and check the dissolved state of the sample cleaning agent in the beaker. The state of dissolution of the cleaning agent was observed after adding room temperature water of 2θθ to each of the samples. In the case of method (4), the cleaning agent of the present invention dissolves and becomes transparent after approximately 3 to 30 minutes, although there are some variations depending on the formulation, whereas the commercially available product dissolves and becomes transparent after 30 minutes or more. It also did not dissolve completely. In the case of using the method of
The detergent of the present invention dissolves instantly and becomes a transparent liquid, but commercially available products sometimes float to the surface of the water or sink to the bottom of the container.
Even after 30 minutes, it did not completely dissolve as in the case of method (4).

The present invention has the above-mentioned structure and has extremely high solubility in water, and it dissolves transparently in a short time without requiring any stirring or other effort just by putting it in water.Since it contains a solvent, it cannot be removed by the builder alone. Even difficult dust and oily substances that stick to a hard film can be cleaned easily and quickly due to the mutual action of the solvent and alkaline detergent, and they dissolve quickly and transparently, so no undissolved substances remain on the cleaning surface. It has a good finish and is particularly effective, for example, as a cleaning agent for washing the windshields of automobiles and other vehicles, and also as a cleaning agent for cleaning the windowpanes of vehicles, houses, etc. No special raw materials are required, and manufacturing is simple and hassle-free.
