Description

Technical Field

[0001] The present invention mainly relates to a foaming detergent composition that can be used in cooking equipment and food processing equipment, and is excellent in detergency, bactericidal property, foam retention property on vertical surfaces, and foam breakability during rinsing.

Background Art

[0002] For detergents used in beverage and food manufacturing factories and kitchens, in order to keep the manufacturing environment hygienic and prevent foreign matter contamination and cross-contamination through manufacturing equipment, facilities such as walls and floors, and manufacturing-related equipment such as filling machines and freezers are washed with alkaline detergents. At that time, in order to improve the detergency and bactericidal property on the object to be washed and to improve the detergent adhesion time, a surfactant is added to the detergent, and a cleaning method is generally used in which compressed air is mixed with a foaming detergent having foaming properties and sprayed in a foamed state.

[0003] The foaming detergent adhering to the object to be washed is rinsed off with water, but the foam breakage during rinsing is poor, and a large amount of water needs to be used, which poses problems in terms of working time and economy. Therefore, in recent years, there has been a strong demand for a foaming detergent that is excellent not only in high detergency but also in foam breakage during rinsing and can shorten the working time.

[0004] Conventional foaming detergents include a quaternary ammonium salt type bactericide, an amine oxide type surfactant having one hydrocarbon group with 8 to 16 carbon atoms, a food processing equipment and / or cooking equipment detergent composition containing one or more compounds selected from fatty acids having 8 to 16 carbon atoms and their salts in a specific ratio (Patent Document 1), a liquid detergent composition containing an alkali agent, an alkali metal silicate, an imidazolinium betaine type surfactant, and a solvent in a specific ratio (Patent Document 2), a cationic bactericide, a biguanide bactericide, and one or more bactericides selected from amino acid bactericides, an alkali agent containing no silicic acid, a nonionic surfactant, an amphoteric surfactant, and a metal chelating agent, and a bactericidal detergent composition having a pH (25°C) of 9 or more in a 1% by weight aqueous solution (Patent Document 3), etc.

This is the gist of it. [Effects of the Invention]

[0010] The foaming cleaning agent composition of the present invention has excellent cleaning power and disinfecting properties against oily stains, and also has good rinsing properties while maintaining foam retention on vertical surfaces, thus enabling a reduction in working time. [Modes for carrying out the invention]

[0011] Component (A) in the foaming detergent composition of the present invention is an alkaline agent. Specifically, examples include alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkanolamines such as monoethanolamine, diethanolamine, triethanolamine, monoisopropanolamine, diisopropanolamine, triisopropanolamine, N-methylethanolamine, and N-methyldiethanolamine; alkali metal silicates such as sodium orthosilicate, sodium metasilicate, sodium silicate No. 1, sodium silicate No. 2, sodium silicate No. 3, sodium silicate No. 4, potassium silicate No. 1, and potassium silicate No. 2; and alkali metal carbonates such as sodium carbonate, potassium carbonate, sodium bicarbonate, and potassium bicarbonate. Among these, sodium hydroxide, potassium hydroxide, potassium carbonate, potassium silicate, monoethanolamine, triethanolamine, and monoisopropanolamine are preferred from the viewpoint of cleaning performance, and sodium hydroxide, potassium hydroxide, potassium silicate, monoethanolamine, and monoisopropanolamine are more preferred. Furthermore, from the viewpoint of good cleaning properties and demonstrating practical metal corrosion prevention, sodium hydroxide, potassium hydroxide, potassium carbonate, sodium silicate, potassium silicate, monoethanolamine, triethanolamine, and monoisopropanolamine are preferred, and among these, sodium silicate, potassium silicate, monoethanolamine, triethanolamine, and monoisopropanolamine are more preferred from the viewpoint of corrosion prevention for aluminum. These may be used individually or in combination of two or more.

[0012] In the foaming detergent composition of the present invention, 100% by mass of component (A) is 0.1% by mass or more, 2 It is preferable that the content be 0% by mass or less, more preferably 1% by mass or more and 15% by mass or less, and even more preferably 1.5% by mass or more and 10% by mass or less. (A) If the content of component is less than 0.1% by mass, the cleaning performance may decrease, and if it exceeds 20% by mass, the storage stability may become insufficient, and it may also corrode metals.

[0013] In the foaming detergent composition of the present invention, component (B) is alkyldimethylaminoacetic acid betaine with an alkyl group having 10 to 18 carbon atoms. The alkyl group refers to an alkyl group bonded to dimethylaminoacetic acid betaine. Specifically, component (B) contains at least tetradecyldimethylaminoacetic acid betaine, and may further contain one or more of the following: decyldimethylaminoacetic acid betaine, dodecyldimethylaminoacetic acid betaine, hexadecyldimethylaminoacetic acid betaine, octadecyldimethylaminoacetic acid betaine, etc. (B) By including tetradecyldimethylaminoacetic acid betaine as component (B), it is possible to provide a foaming detergent composition that has good foaming properties, high foam retention, and high cleaning performance. Generally, when foaming properties and foam retention are good, rinsing properties tend to be poor, but with the composition specified in the present invention, foaming properties are good, high foam retention properties are shown even on vertical surfaces, and foam removal during rinsing is also good.

[0014] In the foaming detergent composition of the present invention, from the viewpoint of cleaning performance and foam retention on vertical surfaces, the proportion of tetradecyldimethylaminoacetic acid betaine in 100% by mass of component (B) is 50% by mass or more, preferably 70% by mass or more, more preferably 80% by mass or more, and particularly preferably 100% by mass. If the proportion of tetradecyldimethylaminoacetic acid betaine in 100% by mass of component (B) is less than 50% by mass, cleaning performance and foam retention on vertical surfaces may decrease. Therefore, for example, when only coconut oil alkyl dimethyl aminoacetate betaine produced using coconut oil (containing 41 to 48% by mass of lauric acid, 16 to 20% by mass of myristic acid, and 9 to 13% by mass of palmitic acid as main components) as the raw material for the component (B) is used, sufficient detergency and foam retention on vertical surfaces may not be obtained. Regarding the present invention, the ratio of tetramethylaminoacetate betaine in the component (B) in the foaming detergent composition includes not only the blending amount of the tetramethylaminoacetate betaine compound alone but also the blending amount of tetramethylaminoacetate betaine contained in composite materials such as coconut oil.

When the content of the component (B) is less than 0.1% by mass, sufficient foaming properties may not be obtained, and the detergency and foam retention on vertical surfaces may decrease. When it exceeds 12% by mass, the storage stability may decrease.
