Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to hard surface cleaning compositions, more specifically,
This invention relates to a cleaning composition for hard surfaces such as glass and ceramics, which has excellent cleaning power and good water drainage after cleaning.

Conventionally, when cleaning tableware that has hard surfaces such as glass or ceramics, water remains on the surface of the items being washed, resulting in white spots (water spots) that spoil the appearance. There were many. These white spots are thought to be heavy metal salts contained in tap water that remain as spots on the surface of glass and other surfaces.

Therefore, in order to improve the finish of glassware, etc., it is only necessary to improve the water drainage after washing, and some compositions that meet such requirements, such as special structures in specific surfactants, are needed. A combination of water-soluble compounds having %O-(172908) and a specific nonionic surfactant for promoting drainage (Japanese Patent Laid-open No. 152897/1989) have been proposed. There is.

However, these compositions still have insufficient effects and are not necessarily satisfactory for practical use.

In view of these circumstances, the present inventors have developed a product with excellent cleaning power,
Moreover, as a result of intensive research to provide an E1 surface cleaning composition that has extremely good water drainage properties after cleaning, we found that a surfactant and a clay that has been swollen with water to a certain degree of swelling in advance. discovered that a detergent composition containing a predetermined proportion could achieve the objective, and based on this knowledge, the present invention was completed.

That is, the present invention uses (A) 5 to 40% by weight of at least one surfactant and (B) 0.2 clay which has been previously swollen with water to a swelling degree of 5/2 or more.
The present invention provides a hard surface cleaning composition characterized in that it contains 10% by weight.

In the aqueous liquid composition of the present invention, the surfactant used as component (A) includes anionic surfactant 1, nonionic surfactant, cationic surfactant, amphoteric surfactant, or zwitterionic surfactant. As the anionic surfactant, ordinary sulfonate-based, sulfate-based, and phosphate-based anionic surfactants are used. Among these anionic surfactants, examples of sulfonate-based anionic surfactants include branched alkyl (C8-C23) benzene sulfone etL with a straight chain name.
& chain alkyl (08-C22) sulfonate, long chain 1st
/fin CCs~C22) sulfonate salts and the like. Sulfate-based anionic surfactants include, for example, long-chain monoalkyl (08-C22) sulfate salts, polyoxyethylene (1-6 mol) long-chain argyl (C8-C22) ether sulfate salts 2, polyoxy Ethylene (1-6 mol) Alkyl (08-Cps)
Examples of the anionic surfactants include phenyl ether sulfate esters, and examples of the anionic surfactants include long-chain monoalkyl, dialkyl, or sesqui(each argyl group has 8 to 22 carbon atoms) phosphorus. Examples include acid salts, polyoxyethylene (1 to 6 moles) mono-alkyl, sialgyl or sesqui (each alkyl group has 8 to 22 carbon atoms) phosphates. Cations as counterions for these anionic surfactants include, for example, sodium,
These include alkali metal ions such as potassium and magnesium, and alkanolamine ions such as monoethanolamine, jetanolamine, and triethanolamine.

Examples of nonionic surfactants include polyoxyethylene (1 to 20 mol) long chain alkyl (primary or secondary 08 to C22) ether, polyoxyethylene (1 to 2 moles),
0 mol) alkyl (08-c18) phenyl ether,
Examples thereof include oxyalkylene addition compounds such as polyoxyethylene polyoxy/propylene block copolymer, higher fatty acid alkanolamide or its alkylene oxide additive, and long-chain tertiary amine oxide (012 to +4).

Examples of the cationic surfactant include quaternary ammonium salts such as long-chain alkyltrimethylammonium salts and long-chain alkyldimethylbenzylammonium L-long alkylpyridinium salts.

Examples of amphoteric surfactants include dimethyl long chain (08-
CI8) alkyl-carboxymethylammonium betaine, di-long chain (08-018) alkylaminoalkylene carboxylate, 2-alkyl-1-carboxymethyl-1-hydro A° diethylimidazolinium betaine, and the like.

These surfactants may be used alone or
Moreover, two or more kinds may be used in combination, and the amount thereof is 5 to 40% by weight, preferably 15 to 305 to 30% by weight, based on the total amount of the cleaning composition. If the amount is less than 5% by weight, the finish and water drainage of the surface of the washed item after washing will be poor.
On the other hand, if it exceeds 40% by weight, a large amount of the surfactant remains on the surface of the items to be washed, resulting in an unpleasant feeling and rinsing takes a long time, which is not preferable.

The clay used as component (B) in the composition of the present invention is swollen in advance with water to a swelling degree of 5 me/li' or more, preferably in the range of l-1.25 to 5 omi/y. , this degree of swelling is 5 rnl/9
If the amount is less than that, no finishing effect after washing will be observed. #Moisture here means, for example, in the case of 25 go/2,
When clay 12 is added to 50 ml of water, the clay swells to a volume of 25 ml.

Examples of the clay include those containing clay minerals such as montmorillonite, nontronite, hectorite, vermiculite, attapulgite, sepiolite and mixtures thereof.

The content of the clay in the composition of the present invention is 0.2 to 1
If the amount is less than 0.2% by weight, the finish feeling after washing will not be improved, and if it exceeds 10% by weight, This is not good because phenomena such as powder residue are observed on the surface of the washed items after washing.

The composition of the present invention may contain other optional ingredients, such as dispersion stabilizers, hydrotropes, viscosity modifiers, fragrances, pigments, preservatives, and antifungal agents, as desired, within a range that does not impair performance. It can also be added.

The hard surface cleaning composition of the present invention is a combination of a surfactant and clay that has been swollen with water in advance, and has excellent cleaning power and extremely good water drainage after cleaning. , and has an excellent finish.

Next, the present invention will be explained in more detail with reference to Examples.

In addition, the water drainage property of the cleaning composition was measured and evaluated as follows.

Is salad oil 3' as dirt in a glass cup with a drainage diameter of 60 mm and a height of 100 mm? Profit evenly.

On the other hand, 4°
Using a 0x90m sponge, wash the inside and outside of the pot 10 times each, and then rinse well with running water. Immediately after rinsing, the water drainage property is visually judged and evaluated in three stages: 0 when there are no water droplets on the surface of the dry tip, × when there are significant water droplets, and △ between the two.

Examples and Comparative Examples Using the clay shown in Table 1, a cleaning composition having the composition shown in Table 2 was prepared, and its drainage properties were evaluated. The results are shown in Table 2.

For comparison, cleaning compositions other than those of the present invention were prepared and their water drainage properties were evaluated in the same manner. The results are also shown in Table 2.
