Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a liquid cleaning composition, and more particularly, the present invention provides a liquid cleaning composition, and more particularly, the present invention provides a liquid cleaning composition that cleans and removes dirt that adheres to and deteriorates on vertical surfaces such as ventilation fans, stoves, walls, ceilings, etc., particularly in the kitchen and its surroundings. The present invention relates to a liquid cleaning composition that can efficiently and safely remove .

Cold oils and fats used at home are altered by the effects of heat, sunlight, trace amounts of metals, oxygen in the air, etc.
Semi-dry solidification or carbonization strengthens the bond with the substrate surface,
It becomes a hard stain and adheres to ventilation fans, ranges, water heaters, vertical parts of walls, ceilings, etc.

For example, a cleaning agent containing a surfactant, an alkaline agent, and a solvent as described in Japanese Patent Publication No. 11688-1988 is effective for cleaning such strong degenerated oil stains adhering to vertical surfaces or ceilings. However, with conventional cleaning agents such as γL, the cleaning agent components volatilize before stains are sufficiently removed, so the cleaning effect is often insufficient.

Therefore, the inventors of the present invention conducted extensive research to solve these drawbacks of liquid cleaning agents, and found that by combining specific water-soluble polymers in the above cleaning agent system, the cleaning agent components do not volatilize. Contact time between cleaning agent ingredients and dirt?
It can be used for a long time and has a remarkable cleaning effect.

The water-soluble polymer compound as component (e) includes polyvinyl alcohol, polyacrylic acid, polymethacrylic acid, or acrylic acid or methacrylic acid and maleic anhydride, fumaric acid, itaconic acid, ethylene, styrene, acrylic ester, and methacrylic acid. Copolymers with acid esters, etc., or their alkali metal salts, ammonium salts, alkylolamine salts: polyvinyl methyl ether, polyvinyl pyrrolidone, polyvinyl sulfone a11. Examples include polyethylene oxide. In particular, partially crosslinked polyacrylic acid or a salt thereof is preferred for this former.

Examples of crosslinking agents for partially crosslinked polyacrylic acid include polyvalent metal salts of acrylic acid or methacrylic acid, glyoxal alkenyl compounds, allylated glycerin, allylated pentaerythritol, allyl (meth)acrylate oligomers, triallyl cyanurate, triallyl phosphate. ,
Examples include one or more selected from tetraallylsilane, polyalkenyl sulfone, and butadiene oligomer.

The amount of these crosslinking agents is preferably from 0.3 to 151 iJi of acrylic acid; if the amount of the crosslinking agent is too small, a sufficient optical viscosity cannot be obtained, and if it is too large, the decomposability deteriorates, which is not preferable.

In addition, partially crosslinked polyacrylic acid has a weight of 2.5%,
It is preferable that the Brookfield yield value of the IJium aqueous solution at 20° C. is 1007/sec/country or higher.

Here, the Brookfield yield value is a value obtained by measuring the apparent viscosity of the above aqueous solution at 20°C and using the following formula, and when the molecular weight is the same, the larger the value, the higher the degree of crosslinking. means.
