Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a liquid cleaning composition, more specifically, which can efficiently and safely remove black to pink mold stains adhering to bathroom tile joints, room walls, etc. The present invention relates to a liquid cleaning composition having a constant viscosity of 1.

Mold, humidity, and heat can grow anywhere if conditions are right, and mold or its excreta will settle, creating black to pink open mold stains. Mold stains are often found in humid areas such as tile joints in bathrooms and washrooms, in ventilated areas, or in the shadows of refrigerators, etc., and mold stains can penetrate deep into the surface and become dull. .

A cleaning agent containing oxidizing bleach is effective for cleaning such mold stains, but is this? l: Because the viscosity of conventional cleaning and cleaning agents containing them is low, when applied to vertical surfaces, they immediately run off and do not exhibit their full effect, and they also scatter and adhere to clean, unnecessary areas. There were a lot of problems when using it.

Unless the oxidizing bleach is used, it is relatively easy to prepare a product with good viscosity and dirt retention, but this does not have sufficient cleaning power.

Therefore, the inventor conducted intensive research to overcome these drawbacks, and as a result, developed a solidifying agent using a specific partially crosslinked polyacrylic acid as a thickener, and an inorganic alkali agent and an alkali or hypochlorous acid agent. We have discovered that when an alkaline earth metal salt is distributed, a liquid detergent composition that has good retention on vertical surfaces, has little scattering, and can easily remove mold stains can be produced by Samurai IL.

The partially crosslinked polyacrylic acid used as a thickener in the present invention has a viscosity of 2.5 JK, Q, and a 2N-NaOH water bath solution of 1. OLI O~16. CJ OOcp with Brookfield yield value of 100-1.600 g
/5ec-α.

Here, the Brookfield yield value is a value obtained by measuring the viscosity of a water bath solution at 20"C and using the following formula. When the molecular weight is the same, the larger the value, the greater the degree of crosslinking. means.

Examples of crosslinking agents for the partially crosslinked polyacrylic acid of the present invention include polyvalent metal salts of acrylic acid or methacrylic acid, glyoxyalkenylated compounds, allylated glycerin, allylated pentaerythritol, and allyl (meth)acrylate. These crosslinking agents include one or more selected from oligomers, triallyl incyanurate, triallyl phosphate, tetraallylsilane, polyalkenyl sulfones, and butadiene oligomers. Preferably, it is %,
If the crosslinking agent is too small, sufficient viscosity cannot be obtained, and if the crosslinking agent is too large, the solubility deteriorates, which is not preferable. It also shows sufficient thickening effect in aqueous solutions with high ionic strength, and shows almost no change in viscosity threshold over time.In contrast, 7FM ordinary polyacrylic acid, polyvinyl alcohol, Locust bean gum etc. do not have sufficient viscosity in an aqueous solution containing an oxidizing bleach.Even if the crosslinking agent is allylated sucrose, diethylene glycol bisallyl ether, Things like diethylene glycol bismethallyl ether have sufficient viscosity when preparing solutions, but
In water bath liquids containing oxidizing bleach, the viscosity decreases significantly over time, especially in the summer when the temperature is high, and the retention of dirt is poor. Not played.

In the present invention, the partially crosslinked polyacrylic acid is contained in the composition in a range of 0.5 to 5%, preferably 0.5 to 6.5%.
- H is added. If the amount of partially cross-linked polyacrylic acid is less than this, the viscosity will be less than 100 cp, and if it is used on a vertical surface, it will quickly run down and form a hole, and if it is more than this, the composition will become gel-like and difficult to use. cause problems.

Examples of the inorganic alkali agents include hydroxides, silicates, carbonates, phosphorus hydroxides, borates, etc. of burka metal, and specific examples include sodium hydroxide, potassium hydroxide, sodium silicate, Examples include sodium carbonate. These alkaline agents are oxidizing bleaches in minutes! It has the effect of preventing i′(k and removing oil stains that are layered on the outside of mold stains.The cations of the alkaline agent are C!a, Mg, A
In the case of polyvalent metals such as 1, etc., the porous nature of the partially crosslinked polyacrylic acid becomes undesirable. These alkaline agents are contained in the composition in an amount of 0.1 to 15%, preferably 0.5 to 15%.

The oxidizing bleach is an alkali or alkaline earth metal salt of hypochlorous acid. Toji-C is one that produces hypochlorite in a water bath, such as the following M←filtered acid: Na, K, Li.

Examples include Oa and Mg salts. These exhibit bleaching and bactericidal effects on mold stains due to the strong oxidizing action of subsalt species. These oxidation whitening agents are present in fibers in amounts of 0.1 to

As the surfactant, cleaning active ingredients used in general urine and garden detergents can be used; , alkyl (08-22) sulfonate, alkyl (08-22) (ffik ester salt, monoalkyl, dialkyl or sesqui(alkyl 08-22)) phosphate, polyoxyethylene (1-6 mol) monoalkyl , sialkyl if 0 sesqui (alkyl 08~

Examples of water-insoluble abrasives include silicon dioxide, aluminum oxide, magnesium oxide, titanium oxide, aluminosilicate, silicon carbide, calcium carbonate, calcium phosphate, chromium oxide or corundum, Emery-1
Examples include crushed natural materials such as silica, quartz sand, dolomite, sand, and shells.

Of these, crushed silica or quartz sand is most commonly used. The grains PL of the abrasive may be coarse, or preferably have a grain size of 2 to 150 microns so as not to damage the surface to be polished. These abrasives are included in the composition.
It is particularly preferable to mix 10 to 6 degrees of weight. This abrasive has the effect of increasing the cleaning effect due to its abrasive effect, and also increasing the layer thickness and extent of the cleaning composition due to its thickening effect and further opacity.
