Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a liquid cleaning composition containing an abrasive with excellent separation stability.

Liquid cleansers containing abrasives are known as liquid cleansers. For example, as shown in Japanese Patent Publication No. 49-23288, a powder of abrasives is added to an aqueous surfactant solution and mixed by stirring. and is manufactured. However, when the abrasive is mixed in the form of powder, air is also introduced into the aqueous surfactant solution, resulting in bubbles, which necessitates a defoaming process. In order to improve this, attempts have been made to add thixotropic clay minerals to cleaning compositions containing abrasives (Japanese Patent Laid-Open No. 56-383).
Publication No. 97, Publication No. 56-145996, Publication No. 56-1
No. 59297, No. 57-96097). The manufacturing method for these is to add abrasives, chain structure clay, other ingredients, etc. to a nonionic surfactant, premix it, and then disperse it with an intermittent shear mixer (##
(Japanese Patent Application Laid-open No. 57-159297), and a method of dispersing the compound by passing it through an orifice twice (Japanese Patent Application Laid-Open No. 57-960).
Publication No. 97), etc. have been reported. However, even with these methods, there is a problem in that air is introduced during powder dispersion and an escape step is required.

Furthermore, it is necessary to exhibit sufficient separation stability by adding layered clay minerals such as smectite, but whereas clay minerals cause delamination in water and swell in the form of flakes between bones, In an aqueous surfactant solution, it takes a long time to interosseous bones, and there is a drawback that the interosseous spaces are insufficient.

The present invention was made in order to eliminate the drawbacks of the prior art as described above, and it is possible to efficiently industrially mass-produce a liquid cleaning composition containing an abrasive.
Moreover, it is an object of the present invention to provide a manufacturing method that can obtain a composition with excellent separation stability.

The abrasive-containing liquid cleaning composition of the present invention has the following (A)
, (Bl and (0) components are mixed.

(A) Aqueous solution containing surfactant.

(B) Aqueous slurry containing water-insoluble abrasive.

(0) Clay mineral-containing aqueous slurry having texotropic properties.

(4) Component surfactant-containing aqueous solution is usually 15 to 70w
Suitably, the composition contains 100% surfactant, preferably 20-40% by weight. As surfactants, anionic surfactants, nonionic surfactants, and zwitterionic surfactants are used. Examples of anionic surfactants include alkyl sulfates, 7/L' + ether sulfate, and alkylbenzene sulfonates. Examples include paraffin sulfonates, olefin sulfonates, and particularly preferred are alkali metal salts, alkaline earth metal salts, ammonium salts, and amine salts.

Examples of the nonionic surfactant include ethylene oxide nonionic surfactants prepared by addition polymerization of ethylene oxide, amides, and semipolar nonionic compounds such as amine oxide. However, as an amphoteric surfactant, 几-N)I-O
H, C00) 1 (R: C.

Examples include amino acid-type amphoteric surfactants such as those represented by straight-chain or branched alkyl groups, and CH1-type amphoteric surfactants.

Among these surfactants, 几, -0(01-1,CH
,O+.

80, M [in the formula, 几 is C, ~8. straight-chain or branched alkyl group, n is the average number of moles added from 1 to 7, M is an alkali metal, alkaline earth metal, ammonium or alkanolamine], C1, to 1° a-olefin sulfonate or inner olefin sulfonate, R19 represents a branched alkyl group, 'fL, and a circle each represent a methyl group or an ethyl group].

The water-insoluble abrasive-containing slurry that is component (B) is usually 2
Suitably it contains 0-75 wt% water-insoluble abrasive, preferably 40-70 wt%. The water-insoluble abrasive material preferably has a Mohs hardness of 2 to 8, and in terms of dispersion stability, the particle size is generally 1 to 150P, preferably 1.
~40p is used. Representative examples of the water-insoluble abrasive include calcite, quartz, silica, alumina, diatomaceous earth, perlite, feldspar, aluminosilicate, calcium phosphate, calcium carbonate, lepidolite, and the like.

There is no problem if the aqueous slurry of component CB) is blended with components (A) and (0) immediately after precipitation, but
When storing for a long time or transporting using a long transport, it is appropriate to add a stabilizer to the aqueous slurry of component (B). Slurries without stabilizers will remain stable for several minutes after dispersing the abrasive in water, forming an abrasive precipitate that is difficult to disperse, while aqueous abrasive slurries containing stabilizers will remain stable for several hours. It is possible to form smudges without requiring strong stirring even after pouring.Also, the dispersibility when added to the raw ingredients is even better, and almost no agglomerates of abrasive particles are formed.

Examples of the stabilizer include 06~. Aromatic sulfonic acids or their salts, C2-carboxylic acids or their salts, etc. are used, and specific examples thereof include benzenesulfonic acid, para-toluenesulfonic acid, xylene sulfonic acids or salts thereof (Na salt, K salt, NH4 salt, alkanolamine salt, etc.), benzoic acid, citric acid, or their salts (Na salt, K salt, etc.) are used. Among these compounds, toluenesulfonic acid or its sodium or potassium salt, benzoic acid's sodium or potassium salt, and citric acid or its sodium or potassium salt are preferred. The stabilizer is used in an appropriate amount of 0.5 to 211 wt%, preferably 2 to 15 wt%, based on the water-insoluble abrasive material. Also,
Since Sin dissolves slowly in an alkaline aqueous solution, the stabilizing agent is N, which exists as a non-kA substance in the abrasive material.
ano.

It also contributes to the neutralization of K2O and CaO.

The clay mineral-containing aqueous slurry that takes care of the thixotropic properties of component (C) contains 0.5 to 10 wt, preferably 3 to 5 wt, of clay minerals having thixotropy.

Clay minerals with chikunthrobi properties include smectite clay minerals and double-chain cypress clay minerals, and specific examples of these include montmorillonite, nontronite,
Examples include hectorite, nonomiculite, athanozeta-rugite, seviolite, and mixtures thereof.

(0) In order to produce the aqueous slurry of component 2, it is appropriate to add clay minerals to water and mix it with a mixer having a high shear force, preferably with a shear force of zoN/d or more. It is possible to obtain an aqueous slurry IJ-'F having an extremely small particle size and good dispersion stability without separation of the water layer.

Prepare the above components (4) to (0) in advance and then mix them. A liquid cleaning composition 8 containing tIF abrasive material is obtained.

This mixture contains 2 to 40% of the surfactant in the cleaning composition.
wt%, 1 to 60 wt% of abrasive and 0.0 wt% of clay mineral.
It is appropriate to carry out the surfactant so that the surfactant 7i contains 1 to 5 wt%, more preferably 3 to 15 wt% of each surfactant 7i.

A cleaning composition containing t%.

The order in which the above components are mixed does not matter. First, component (5) and component (J3) are mixed, and then this mixture and component (0) are mixed to improve the separation stability of the resulting composition. Further improvements can be made.

As for the mixing method, for example, after charging the component (A) into a mixing tank equipped with a normal stirring blade, the components (B) and (C) may be sequentially added while stirring. In this case, special
The component (0) is preferably added continuously into the liquid. At this time, in tank mixing, (0) is equal to or lower than the discharge flow rate of (A) + (B) in stirring, and at a flow rate lower than the circumferential speed of the stirring blade, and in pipe mixing, (C)
It is clever to add at a flow rate equal to or lower than the average volumetric flow rate of (A) + (B). Also, using a line mixer or motionless mixer, (A), (B)
% (C) component may be simultaneously mixed in a pipe. Specific examples of mixer usage include T as a line mixer,
Examples of the mixer include a pipeline homo mixer (manufactured by % Sukumika Kogyo Co., Ltd.) and a static mixer (manufactured by Kenics, USA) as a motionless mixer.

In addition, the cleaning composition of the present invention may optionally contain lower alcohols (01-m), fragrances, pigments, bactericidal agents,
enzymes, mono(di- or tri)ethanolamine, etc.
A Hu buffering agent can also be added. These optional components may be added to each component in advance, or each component may be added to the concave bales, but it is appropriate to add them to component (4) in advance. Forward, the addition of fragrance is smectite ＼ absorption M
Considering this, it is particularly preferable to add it at the end of the formulation.

According to the production method of the present invention, it is possible to sufficiently intersect the clay red material to exhibit excellent separation stability, and to suppress foaming, thereby producing a cleaning agent composition f&:4 containing abrasive material. I can do it,
This is an extremely industrially advantageous method.
