Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a foaming detergent composition. In particular, foaming properties that can satisfactorily remove dirt that has deteriorated over a long period of time due to oil adhering to the kitchen and its surroundings, such as ventilation fans and range hood filters, are safe for the human body, and significantly reduce cleaning labor. The present invention relates to a cleaning composition.

[Conventional technology]

Oil and fat stains on polished rice often deteriorate due to the effects of heat, sunlight, oxygen during observation, etc., and are in a sticky resin-like or semi-dry state.

To prevent such deterioration oil stains,
Strong alkaline type 1 residential cleaning agent as shown in the publication, i.e., a cleaning agent consisting of alkali agents such as ammonia, monoethanolamine, sodium hydroxide, water-soluble agents such as selonulp and calpitol, and a surfactant. It had been cleaned with a composition.

[Problem that the invention seeks to solve]

However, such strong alkaline residential cleaning
6b/A-, which contains complicated parts such as range hood filters and ventilation fans, cannot be cleaned, and when considering safety for the human body, sufficient care must be taken when using them. Furthermore, when cleaning with a strong alkaline household detergent, not only did the cleaning process require a great deal of effort, but the finished product was sticky, making it impossible to obtain a satisfactory finish. [Means for Solving the Problems] In order to solve the above problems, the inventors of the present invention have conducted extensive research and have found a method that has sufficient cleaning power for denatured oil and fat stains, is safe for the human body, and significantly reduces cleaning work effort. We have now invented the foaming detergent composition of the present invention that can reduce the amount of water used.

That is, the present invention contains 20 to 50% by weight of carbonate and 20 to 50% by weight of organic acid.
The present invention provides a foaming detergent composition comprising 50% by weight of a surfactant and 1 to 10% by weight of a surfactant whose surface tension lowering ability does not exceed 45 dyne/brass.

Examples of the carbonate to be incorporated into the foaming cleaning composition of the present invention include sodium hydrogen carbonate, sodium carbonate, sodium sesquicarbonate, potassium hydrogen carbonate, potassium carbonate,
Potassium sesquicarbonate, ammonium bicarbonate salt, ammonium carbonate salt, ammonium sesquicarbonate salt, etc. are mentioned, and these can be used alone or in combination of two or more kinds.

In addition, the organic acid is preferably water-soluble and solid;
Short-chain aliphatic carboxylic acids having 1 to 6 carbon atoms, oxyacids or their acid salts, acidic abano acids or their acid salts, aromatic carboxylic acids or their acid salts, nicotinic acid, kainic acid, rubic acid, benzenesulfone ], 1-luenesulfonic acid and pyrrolidonecarboxylic acid 4? can be mentioned. Examples of oxyacids include gelcholic acid, lactic acid, α-
Oxybutyric acid, glyceric acid, tartronic acid, malic acid,
Aliphatic oxyacids such as tartaric acid, citric acid, ascorbic acid, and glucone; aromatic oxyacids such as salicylic acid, gallic acid, mandelic acid, and trobic acid. Furthermore, examples of acidic amino acids include glutamic acid and aspartic acid. Examples of aromatic carboxylic acids include cinnamic acid, benzoic acid, 7-enyl acetic acid, phthalic acid, inphthalic acid, terephthalic acid, and trimellitic acid.

In the present invention, in order to increase the suction power of foam against dirt, a surfactant whose surface tension lowering ability does not exceed 45 dyne/river is used in an amount of 1 to 10% by weight, preferably 4 to 10% by weight.
Mix within the range. If it is less than 1%, the effect is not sufficient and 10
%, the physical cleaning effect due to foaming decreases.

Preferred surfactants whose surface tension lowering ability does not exceed 45 dynθ/(Fll) are those of the following general formulas (a) to (0
) It is preferable to use one or more of the following nonionic surfactants, anionic surfactants, and amphoteric surfactants.

R-0-P-ONa [R represents the meaning described above] (c)　　　　R.

R-N → O In particular, nonionic surfactants preferably have 10 to 14 carbon atoms and 6 to 10 moles of ethylene oxide, and L
Among them, polyoxyethylene lauryl ether is preferable, for anionic surfactants, mono-long chain alkyl phosphates with an alkyl group of 12 to 14 carbon atoms are preferable, and for amphoteric surfactants, tertiary amine oxides are preferable. Those having 12 to 14 alkyl groups are preferred, and are used in combinations of 1 or 2i or more. Surfactants whose surface tension is lower than 45 dyne/-, and those whose surface tension lowering ability exceeds 45 dyne/(Nk) are not preferred because they tend to reduce detergency.In the present invention, A surfactant with a surface tension lowering ability exceeding 45 dyne Z city is defined as a 0.1% aqueous solution of a surfactant at 20°C.
This means a surfactant with a surface tension of 45 dyn8/(m or more, preferably 60 dyna/m or less).If a surfactant with a surface tension of 45 to 6adyn6/aP& is used, the size of the generated bubbles and It is presumed that strength (stability) is maintained appropriately, dirt is easily adsorbed, and cleaning power is improved.

In addition, builder components such as carboxymethyl cellulose, polyacrylates, and alginates, colorants, fragrances, and bactericidal agents may be used in the foaming detergent composition of the present invention, as appropriate.

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 quintillion percent by weight, but the concentration can be adjusted as appropriate depending on the temperature at which it is used and the degree of contamination of the object to be cleaned.
