As disclosed in Japanese Patent Laid-Open Publication No. JP-A-2003-101240, a detergent composition comprising an alkaline strong type detergent for household use, that is, an alkaline agent such as ammonia, monoethanolamine, sodium hydroxide, cellosolve, a water-soluble solvent for carbitols, and a surfactant. Had been washed in.

[Problems to be solved by the invention]

However, in such an alkaline strong type residential potential, the complicated parts such as the filter and the ventilation fan of the range hood cannot be washed, and in consideration of safety to the human body, sufficient caution should be taken when using it. I had to pay. Furthermore, when washing is performed using a strong alkaline type household detergent, not only a great amount of labor is required for the washing work, but also the washing is sticky and a satisfactory finished feeling cannot be obtained.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above problems, the present inventors have sufficient cleaning power for modified oil and fat stains, are safe for the human body, and can significantly reduce the cleaning work effort. Invented a pharmaceutical composition.

That is, the present invention uses 20 to 50% by weight of carbonate and
Provided is a foaming detergent composition containing 50% by weight and 1 to 10% by weight of a surfactant whose surface tension lowering ability does not exceed 45 dyne / cm, and which does not contain percarbonate and is used for cleaning modified oil and fat stains. Is.

Examples of the carbonate to be added to the foaming detergent composition of the present invention include sodium hydrogen carbonate, sodium carbonate, sodium sesquicarbonate, potassium hydrogen carbonate, potassium carbonate,
Examples thereof include potassium sesquicarbonate, ammonium hydrogencarbonate, ammonium carbonate, ammonium sesquicarbonate and the like, and these can be used alone or in combination of two or more kinds.

The organic acid is preferably water-soluble and solid,
Short-chain aliphatic carboxylic acids having 1 to 6 carbon atoms, oxyacids or acid salts thereof, acidic amino acids or acid salts thereof, aromatic carboxylic acids or acid salts thereof, nicotinic acid, kainic acid, sorbic acid, benzenesulfonic acid, toluene Examples thereof include sulfonic acid and pyrrolidonecarboxylic acid. Examples of oxyacids include aliphatic oxyacids such as glycolic acid, lactic acid, α-oxybutyric acid, glyceric acid, tartronic acid, malic acid, tartaric acid, citric acid, ascorbic acid and gluconic acid; salicylic acid, gallic acid, mandelic acid, Aromatic oxyacids such as tropic acid are mentioned. Examples of acidic amino acids include glutamic acid and aspartic acid. Further, examples of the aromatic carboxylic acid include cinnamic acid, benzoic acid, phenylacetic acid, phthalic acid, isophthalic acid, terephthalic acid and trimellitic acid.

In the present invention, in order to increase the adsorptivity of bubbles to stains, a surfactant whose surface tension lowering ability does not exceed 45 dyne / cm is added in an amount of 1 to 10% by weight, preferably 4 to 10% by weight. To do. If it is less than 1%, the effect is not sufficient, and if it exceeds 10%, the physical cleaning effect due to foaming deteriorates.

As a preferred surfactant having a surface tension lowering ability not exceeding 45 dyne / cm, one of nonionic surfactants, anionic surfactants and amphoteric surfactants represented by the following general formulas (a) to (c): Alternatively, it is preferable to use two or more kinds.

(a) (b) (c) In particular, nonionic surfactants having 10 to 14 carbon atoms and 6 to 10 moles of ethylene oxide added are preferable, and particularly polyoxyethylene lauryl ether, and anionic surfactants having an alkyl group having 12 to 14 carbon atoms. Of the long-chain alkyl phosphates and amphoteric surfactants, tertiary amine oxides are preferable, and those having an alkyl group having 12 to 14 carbon atoms are particularly preferable, and one type or a combination of two or more types is used. Surface tension of surfactant is 45 dyne / cm
Lower value, ie the surface tension lowering ability is 45 dyne / cm
Those that exceed 10 are not preferable because the detergency tends to be lowered. In the present invention, the surfactant whose surface tension lowering ability does not exceed 45 dyne / cm means that the surface tension of a 0.1 wt% aqueous solution of the surfactant at 20 ° C. is 45 dyne / cm or more,
It preferably means 60 dyne / cm or less. When a surfactant having a surface tension of 45 to 60 dyne / cm is used, the generated bubble size and strength (stability) are appropriately maintained,
It is presumed that dirt can be easily adsorbed and the cleaning power is improved.

The modified oil and fat stain cleaning foamable detergent composition of the present invention does not include percarbonates such as sodium percarbonate, but builder components such as carboxymethyl cellulose, polyacrylates, alginates, colorants, perfumes, and sterilization. You may use it, adding an agent etc. suitably.

When using the foaming detergent composition of the present invention, the concentration is 0.1.
It is usually used as an aqueous solution of 10 wt%, but its concentration can be appropriately used depending on the degree of contamination of the washing product at the use temperature.
