Description

TECHNICAL FIELD The present invention relates to a detergent composition. More specifically, the present invention relates to a detergent composition that exhibits excellent detergency for metals, glass, ceramics, etc. and has a good feeling in use.

(Prior Art) As a cleaning agent for tableware, cooking utensils, and the like, more cleaning agents than ever have been used. Various surfactants are used as the active ingredients of these detergents.

As the surfactant, those having a non-polar group exhibiting lipophilicity and a polar group exhibiting hydrophilicity in the same molecule are known,
It is divided into several groups depending on the form of the polar group contained in the molecule.

Generally, household cleaning agents are mainly composed of anionic surfactants having an anion in a polar group, which are used for emulsification, solubilization, etc. of target pollutants. Excellent in so-called detergency. However, this is a mold contained in pollutants and others,
Lack of bactericidal activity against bacteria.

In order to make up for the above-mentioned drawbacks, it is considered to mix a zwitterionic surfactant, which is said to have a strong bactericidal activity. However, although the zwitterionic surfactant itself has a detergency, when the compounding amount increases, the object to be washed, especially glass,
If applied to smooth surface materials such as ceramics and metal,
There is a drawback in that the so-called sticky feeling due to the activator adhering becomes large and the usability becomes poor. Further, the anionic surfactant and the zwitterionic surfactant themselves are poorly compatible with each other and have a drawback that they are separated from each other in an aqueous solution.

(Problems to be solved by the invention) Therefore, if the excellent properties of the anionic surfactant and the zwitterionic surfactant can be combined and the above drawbacks can be overcome, an excellent detergent can be obtained. It has been considered difficult to make a stable system in which two components are uniformly mixed or dispersed in water.

However, the present inventors have found that the above-mentioned drawbacks can be solved by combining a specific silicate mineral with the above-mentioned two kinds of activators, and finally, the detergent composition of the present invention has been obtained.

(Means for Solving Problems) That is, the present invention relates to 100 parts by weight of layered silicate mineral, 50 to 1000 parts by weight of anionic surfactant, and zwitterionic surfactant.
The present invention provides a detergent composition in which 50 to 1000 parts by weight are mixed.

In the present invention, the layered silicate mineral is generally called a clay mineral, and refers to a layered layered laminated structure. Particularly, smectite-type clay minerals such as montmorillonite, beidellite, saponite, hectorite, and stevensite are preferred. In the present invention, it is recommended to use aponite.

The above-mentioned layered silicate mineral can be obtained by artificially synthesizing a plurality of inorganic compounds as starting materials according to the method disclosed in JP-A-58-181718, for example. In addition, high-purity substances such as montmorillonite can be obtained by extracting from natural swelling clay as a starting material by a method called elutriation. In the present invention, as long as a high-purity layered silicate mineral is obtained,
The type and manufacturing method are not particularly limited.

The above-mentioned clay mineral is preferably used in a system dispersed in water, and specifically, it is used in a state of 0.5 to 10% by weight of a water dispersion liquid, but the dispersion liquid causes so-called mamako, lumps, etc. As long as it is manufactured so as not to do so, its preparation method is not particularly limited.

Next, in order to produce the composition of the present invention, the amount of the anionic surfactant used is in the range of 50 to 1000 parts by weight, based on 100 parts by weight of the silicate mineral, and the amount thereof is small. If so, the detergency as a detergent is remarkably lowered and it becomes impractical. On the other hand, if the blending amount is too large, it becomes difficult to uniformly disperse the activator using the silicate mineral, which is not preferable. More preferably, the amount of the anionic surfactant is 100 to 500 parts by weight with respect to 100 parts by weight of the silicate mineral.

On the other hand, the compounding amount of the zwitterionic surfactant used for producing the composition of the present invention is in the range of 50 to 1000 parts by weight with respect to 100 parts by weight of the silicate mineral. If the amount is too small, the bactericidal action is insufficient, while if the amount is too large, it becomes difficult to uniformly disperse the surfactant using the silicate mineral, which is not desirable. In addition, the blending amount of the two kinds of surfactants is not limited to the dispersibility in silicate,
It is recommended to determine it in consideration of the function as a detergent such as the detergency and sterilization ability of the intended detergent composition.

Examples of the anionic surfactant used in the present invention include sodium alkyl sulfate ester, sodium olefin sulfate ester, sodium alkylbenzenesulfonate, sodium alkylnaphthalenesulfonate, sodium acyloxy, dialkylsulfosuccinic acid sodium salt, alkylbenzenesulfonic acid alkanolamide, and alkyl. An organic sulfonate such as a sulfate ester salt of alcohol ether, an organic carboxylate, an alkylphenyl ether phosphoric acid or a derivative pair derived from these acids is used.

On the other hand, as the zwitterionic surfactant, for example, an alkyl betaine, an alkyldiethylene triaminoacetic acid, an N-alkylglycine derivative, a derivative of glycine from a quaternary ammonium salt group, and the like, a carboxyl group, a sulfonate, and a carboxylate are included in the molecule. And anion-forming functional group and anion group, imino group, nitrilo group and quaternary ammonium salt group.

In the detergent composition of the present invention, another substance having a detergency,
For example, addition of a cationic surfactant or nonionic surfactant, and addition of a fragrance, a dye, an optical brightener, a dispersant or the like does not impair the purpose of the present invention.

(Effects of the Invention) The cleaning composition of the present invention is uniformly dispersed in water to
Used as an aqueous dispersion of 35% by weight, preferably 5-25% by weight, but due to the silicate mineral present in the composition,
No phenomenon of releasing any active agent is observed. It is speculated that this is because the cation of the zwitterionic surfactant is trapped due to the high cation exchange capacity of the silicate mineral, and the cation acts as a water-acid solution similar to the anionic surfactant. But I'm not sure yet. Therefore, when a predetermined amount of the cleaning composition of the present invention is extracted, a predetermined amount of the blended component is always present therein in a stable concentration and dispersed.

Further, since the aqueous dispersion of the detergent composition of the present invention has a high viscosity, when the object to be cleaned, for example, a plate-shaped object is made vertical and the aqueous dispersion is applied to the surface thereof, it sags. This will be considerably suppressed, and the cleaning will be easily performed.

Moreover, the detergent composition of the present invention does not have a so-called sticky feeling on the skin in the course of the washing operation and gives a very comfortable feeling of use.

It should be noted that, since the components having the cleaning power and the bactericidal power are uniformly present in the cleaning composition, it is possible to effectively clean the target. Further, when the cleaning composition is removed with clean water after the cleaning with the cleaning composition, it can be carried out in the same manner as in the case of using the conventional detergent.

(Examples) The present invention will be described in more detail based on the following examples, but the present invention is not limited to these examples. In the examples, parts are parts by weight unless otherwise specified.

Example 1 The following surfactants manufactured by Toho Chemical Industry Co., Ltd. were used. That is, Obanol 516 (main component is glycine-type amphoteric surfactant polyoctyl-polyaminoethylglycine: hereinafter referred to as Activator A), Tohoru N230X
(Highly active lauryl diethanolamide: hereinafter referred to as Activator B) and (Lunox S-40T (40% aqueous solution of triethanolamine dodecylbenzenesulfonic acid; hereinafter referred to as Activator C).

Next, in order to disperse the above-mentioned active agent in water, a serogen (carboxymethyl cellulose: manufactured by Dai-ichi Kogyo Seiyaku Co., Ltd .:
CMC) and Kunimine Industries Co., Ltd.'s Smecton S
Two kinds of A (a colloidal hydrous silicate-a clay mineral containing smectite as a main component and a cation exchange equivalent of 71 meq / 100 mg) were used.

Three types of cleaning agents were prepared as described below.

Detergent 1 Activator A was dissolved in water to give a 10% solution.

Detergent 2 An aqueous CMC solution was prepared by dissolving 3 parts of CMC in an appropriate amount of water. Next, 5 parts of activator B, 10 parts of activator C, and 10 parts of activator A
Collect 10 parts each, add to CMC aqueous solution, mix,
Water was added to adjust the total amount to 100 parts.

Detergent 3 In the same manner as in the preparation of Detergent 2, except that 3 parts of smecton SA and 0.2 part of CMC were used in place of 3 parts of CMC used in detergent 2, smecton SA was contained. A cleaning composition was prepared.

Next, using a monitor of 50 women, a cleaning test with the above-mentioned three kinds of cleaning agents was carried out with bare hands using tableware made of metal, glass and earthenware dipped in cooking oil. Regarding the feeling of use of the cleaning agent (especially, sticky feeling on the hand), the one having no problem was evaluated as 2 points, the sticky feeling was evaluated as 0 point, and the non-sticky feeling was evaluated as 1 point. As a result, cleaning agent 1
Was 10 points, cleaning agent 2 was 40 points, cleaning agent 3 was 99 points, and it was found that cleaning agent 3 had a good feeling in use.

It should be noted that the cleaning agent 2 had a slightly lower foaming property in use than the cleaning agent 3, and thus the monitor tends to be used more often during the cleaning operation. When preparing the cleaning agent 2, it is necessary to add CMC in an amount of 3% by weight or more in order to prevent layer separation.
However, it was found that the cleaning agent 2 became extremely viscous and deteriorated the foamability during cleaning work.

Further, regarding the degree of removal of stains on tableware, the cleaning agent 3 did not show a significant difference from the other cleaning agents.

Reference Example 2 A detergent was prepared in the same manner as in the detergent 3 except that 0.2 part of CMC was used in place of 3 parts of smecton SA and 0.2 part of CMC in the detergent 3. This cleaning agent is called cleaning agent 4.

Using the cleaning agents 2, 3 and 4, the cleaning power comparison test
The cleaning performance was evaluated according to JIS K3370. As a result, it was confirmed that the cleaning agents 3 and 4 have the same cleaning power. The same was true in the experiments comparing the cleaning agents 2 and 3.

That is, the effect of adding Smecton SA to the detergent was not observed.

Example 2 In addition to Lunox S-40T (hereinafter referred to as activator A1) used as an anion activator in Example 1, Alscope TAP-30 (manufactured by Toho Chemical Industry Co., Ltd .: main component is a lauryl alcohol ether sulfate ester) Sodium salt-hereinafter referred to as activator A2), Alscope LN-40A (manufactured by Toho Chemical Industry Co., Ltd .: sodium salt of lauryl alcohol sulfate-hereinafter referred to as activator A3) or GafacPE-510 (manufactured by Toho Chemical Industry Co., Ltd.) : The main component is an alkyl phenyl ether type phosphoric ester, the alkyl group has 8 to 30 carbon atoms, and the ether is an unspecified repeating unit of -CH ₂ CH ₂ O-, and ROCH ₂ CH ₂ forms a phosphoric ester. O _n group 1 in one molecule
Includes an unspecified number of ~ 2-hereinafter activator A4), and as a zwitterionic activator, in addition to Obanol 516 (hereinafter activator B1), Nissan Anon BF (Nippon Yushi-Seiyaku Co., Ltd .: main component is Dimethyl palm alkyl betaine, palm alkyl refers to an alkyl group derived from palm oil, the main component of the alkyl group is a mixture of those having 10 to 14 carbon atoms-hereinafter referred to as activator B2), In addition to smecton SA (hereinafter referred to as mineral C1) as layered silicate mineral, Kunipia F (Kunimine Industries Co., Ltd.)
Made: high-purity sodium montmorillonite-hereinafter referred to as mineral C2) or Laponite XLS (manufactured by Laposte, USA: synthetic hectorite-hereinafter referred to as mineral C3) using an anion activator and zwitterionic activity as shown in Table 1. Detergent 3 of Example 1 with a combination of agents and minerals (however, Tohoru N230
A cleaning composition was prepared based on the method shown in (X is not compounded), a cleaning test of the cleaning agent was carried out by a female monitor, and the feeling of use was evaluated. The results are shown in Table 1.

When mineral C3 was used, in order to increase the viscosity of the detergent composition, 8 parts was used as opposed to 3 parts for other minerals.

In addition, in Experiment No. 1 (Comparative Example), a commonly used sodium polyacrylate (first-grade reagent) was used instead of the mineral. In this case, the experiment was conducted without adding CMC.

As is clear from the results shown in Table 1, the cleaning agents according to the present invention (Experiment Nos. 2 to 21) have obtained excellent evaluation points.

However, when C2 was used as the silicate mineral, the amount of the amount used was large, and the resulting cleaning composition was dull, and the appearance was worse than the others, and that was added to the evaluation points. The value was a little low.

On the other hand, in the comparative example (Experiment No. 1), the detergent composition had spinnability, had a slightly sticky feeling, and had a low evaluation point.
