[0001] The present invention relates to a detergent composition which is excellent in cleaning properties, foaming properties, foam retention on vertical surfaces, etc., as well as in foam removal properties during rinsing and storage stability, and which can be used efficiently to clean and disinfect floors, walls, etc. of cooking equipment, food and beverage manufacturing and processing equipment, and factories. [Background technology]

[0002] Detergents used for cleaning hard surfaces such as floors and walls in food and beverage manufacturing plants and kitchens are required to have high cleaning power against oil and protein stains, and also to have disinfecting power against food poisoning bacteria and other pathogens. In order to effectively clean and disinfect vertical surfaces such as walls, the detergents must have good foaming power, good foam adhesion and retention on the wall surface, and good foam removal during rinsing to reduce work time and save water.

[0003] Known examples of detergent compositions used for cleaning this type of hard surface include a detergent composition containing an alkaline agent, an anionic surfactant, an alkyldimethylamine oxide, and a fatty acid or a salt thereof (Patent Document 1), a detergent composition containing an amine oxide, a branched fatty acid or a salt thereof in a specific ratio (Patent Document 2), and a detergent composition containing multiple specific amine oxides and two specific types of fatty acids and having a pH of 13.3 or higher (Patent Document 3).

In addition, the detergent composition of the present invention has foaming properties and excellent foam adhesion and retention, so that it exhibits excellent cleaning properties even on vertical surfaces such as walls. Furthermore, the detergent composition of the present invention has good foam-breaking properties during rinsing, and can be efficiently rinsed with a small amount of water, so that cleaning and sterilization can be performed efficiently and effectively. The detergent composition of the present invention can effectively clean and sterilize surfaces to be cleaned made of various materials, and is particularly suitable for cleaning and sterilizing hard surfaces such as floors and walls in beverage and food manufacturing and processing plants and kitchens.

[0010] The cleaning composition of the present invention having such a constitution fully satisfies the requirements for cleaning performance, foaming property, and foam adhesion and retention, and is also excellent in disinfecting properties and foam removal during rinsing.

[0011] The use of the cleaning composition of the present invention is not particularly limited, and it can be suitably used, for example, as a cleaning composition for foaming cleaning of hard surfaces composed of aluminum and the like. The constitution of the liquid detergent of the present invention will be described in detail below.

[0012] The cleaning composition of the present invention contains an amine oxide as component (A). The amine oxide (A) is represented by the general formula R + -O - In component (A), R represents a hydrocarbon group, and it is preferable that one of the three hydrocarbon groups has 8 to 18 carbon atoms, and it is more preferable that two of the hydrocarbon groups are methyl groups. The hydrocarbon group having 8 to 18 carbon atoms may be an alkyl group or an alkenyl group. The amine oxide of component (A) may be one type, or may be a combination of two or more types.

[0014] From the viewpoint of exhibiting good rinsing properties in addition to cleaning properties and foam retention, it is preferable that the component (A) contains octyldimethylamine oxide in addition to dodecyldimethylamine oxide and / or tetradecyldimethylamine oxide.

[0015] When the component (A) contains at least tetradecyldimethylamine oxide and dodecyldimethylamine oxide, the dodecyldimethylamine oxide is preferably blended in an amount of 0.01 part by mass or more and 1 part by mass or less, and more preferably 0.02 part by mass or more and 0.5 part by mass or less, per 1 part by mass of tetradecyldimethylamine oxide.

[0016] The (A) component mainly contributes to the foam retention and cleaning properties of the cleaning composition of the present invention. Therefore, if the amount of the (A) component is too small, the foam retention and / or cleaning properties may be insufficient. On the other hand, if the amount of the (A) component is too large, the storage stability may be insufficient. From this viewpoint, the content of component (A) in the cleaning composition is preferably from 0.1 to 10.0 mass%, more preferably from 0.5 to 7.0 mass%, and particularly preferably from 1.0 to 5.0 mass%.

[0017] The present invention includes a branched fatty acid and / or a salt thereof having a total carbon number of 12 to 24 as component (B). By combining component (B) with component (D) described later, a detergent composition having a good balance of foam retention, rinsing ability, and disinfecting ability can be easily realized, and from the viewpoint of being particularly excellent in at least one of the evaluations of foam retention, rinsing ability, and disinfecting ability, the total carbon number in component (B) is preferably 14 to 24, more preferably 16 to 24, and particularly preferably 18 to 24. The branched fatty acid and / or salt thereof as component (B) may be one type or a combination of two or more types. In the present invention, the branched fatty acid refers to a fatty acid having a branched chain, and may be a saturated fatty acid or an unsaturated fatty acid, and is preferably a saturated fatty acid.

[0018] Examples of the branched fatty acid and / or salt thereof having a total carbon number of 12 or more and 24 or less as component (B) include isolauric acids such as 2-methylundecanoic acid and 10-methylundecanoic acid; isomyristic acids such as 2,2-dimethyldodecanoic acid, 2,3-dimethyldodecanoic acid, and 2-butyl-3-methylnonanoic acid; isopalmitic acids such as 2-methylpentadecanoic acid, 3-methylpentadecanoic acid, 2-butyldodecanoic acid, 2-butyldodecanoic acid, 2-hexyldecanoic acid, and 2-heptylnonanoic acid; Examples of the isostearic acids include butadecanoic acid, 2-ethylhexadecanoic acid, 2-octyldecanoic acid, and 2,2-dimethylhexadecanoic acid; isoarachidic acids such as 3-methylnonadecanoic acid, 18-methylnonadecanoic acid, 2,2-dimethyloctadecanoic acid, 2,4-dimethyloctadecanoic acid, and 2-butyl-2-heptylnonanoic acid; isobehenic acids such as 20-methylheneicoic acid; isolignoceric acids such as 3-methyltricoic acid, and salts thereof, and combinations of two or more thereof may be used.

[0019] Examples of the salts of the branched fatty acids include sodium salts, potassium salts, calcium salts, magnesium salts, ammonium salts, alkanolamine salts, etc., with sodium salts and potassium salts being preferred.

[0020] From the viewpoint of exhibiting better foam retention and rinsing properties, it is preferable that component (B) contains one or a combination of compounds selected from the group consisting of isopalmitic acid or a salt thereof, isostearic acid or a salt thereof, and isoarachic acid or a salt thereof, and it is more preferable that component (B) contains at least isoarachic acid and / or a salt thereof.

[0021] The (B) component contributes to the foam retention and / or rinsing properties of the cleaning composition of the present invention. Therefore, if the amount of the (B) component is too small, the foam retention and / or rinsing properties may be insufficient. On the other hand, if the amount of the (B) component is too large, the storage stability may be insufficient and the disinfecting properties may be undesirably affected. From such a viewpoint, the content of the (B) component in the detergent composition is preferably from 0.01% by mass to 5.0% by mass, more preferably from 0.05% by mass to 3.0% by mass, and particularly preferably from 0.1% by mass to 1.0% by mass. When the (B) component contains a branched fatty acid salt, the content of the (B) component in the detergent composition of the present invention is the content calculated from the amount of the branched fatty acid salt converted into branched fatty acid.

[0022] The present invention contains an alkaline agent as component (C). Examples of the alkaline agent as component (C) include alkali metal hydroxides, alkaline earth metal hydroxides, alkali metal carbonates, alkali metal silicates, alkanolamines, etc. Component (C) may contain one type of alkaline agent or two or more types of alkaline agents.

[0025] The component (C) contributes to the cleaning properties and / or metal corrosion prevention properties of the cleaning composition of the present invention. If the amount of the component (C) is too small, the cleaning properties may be insufficient. On the other hand, if the amount of the component (C) is too large, the metal corrosion prevention properties may be insufficient, and the rinsing properties and storage stability may also be adversely affected. From this viewpoint, the content of component (C) in the cleaning composition is preferably from 0.1 to 10.0 mass%, more preferably from 0.3 to 5.0 mass%, and particularly preferably from 0.8 to 4.0 mass%.

[0026] The cleaning composition of the present invention contains a cationic surfactant as component (D). Examples of the cationic surfactant that is the component (D) include quaternary ammonium salt-type cationic surfactants such as dialkyl dimethyl ammonium salt, alkyl trimethyl ammonium salt, alkyl dimethyl ethyl ammonium salt, dialkyl ethyl methyl ammonium salt, dialkyl monomethyl hydroxyethyl ammonium salt, alkyl dimethyl benzyl ammonium salt, alkyl dimethyl hydroxyl ethyl ammonium salt, alkyl dipolyoxyethylene methyl ammonium salt, alkyl dipolyoxyethylene methyl ammonium salt, alkyl pyridinium salt, and benzethonium salt; guanidine-based cationic surfactants such as polyhexamethylene biguanide hydrochloride, polyhexamethylene guanidine phosphate, polyhexamethylene guanidine chloride, and chlorhexidine gluconate; hexadecyl tributyl phosphonium, alkyl diamine, and salts of the above-mentioned compounds. The cationic surfactants exemplified above may be contained as the component (D) in a single type or in a combination of two or more types.

[0027] From the viewpoint of exhibiting more excellent disinfecting properties, it is preferable to contain a quaternary ammonium salt type cationic surfactant as the component (D). The quaternary ammonium salt cationic surfactant contained in component (D) preferably has an alkyl group having 1 to 22 carbon atoms, more preferably has an alkyl group having 4 to 22 carbon atoms, and even more preferably has a linear alkyl group having 6 to 18 carbon atoms. The component (D) may be a mixture of two or more compounds that have a common skeleton but have different numbers of carbon atoms in the alkyl group.

[0028] From the viewpoint of exerting excellent disinfecting properties, it is particularly preferable to contain a quaternary ammonium salt type cationic surfactant represented by the following general formula (1) as component (D). The quaternary ammonium salt represented by general formula (1) is unlikely to form a complex with the anion in the detergent composition, and exerts excellent disinfecting properties. Two or more compounds having the skeleton represented by the following general formula (1) and having different numbers of carbon atoms in the alkyl group can be used as component (D). [ka] (In the formula, R 1 ~R 3 represents an alkyl group having 1 to 18 carbon atoms, X represents a halogen atom, R 1 ~R 3 At least one of the above is an alkyl group having 8 to 18 carbon atoms.)

[0029] The halogen atom (X) shown in the above general formula (1) is not particularly limited, and can be selected from the group consisting of, for example, a chlorine atom, a bromine atom, and an iodine atom. Because of its high versatility, a chlorine atom or a bromine atom is preferred as X, and a chlorine atom is more preferred. For example, specific examples of the (D) component represented by the above general formula (1) include lauryl dimethyl hydroxyethyl ammonium chloride (monododecyl dimethyl hydroxyethyl ammonium chloride) and myristyl dimethyl hydroxyethyl ammonium chloride (monotetradecyl dimethyl hydroxyethyl ammonium chloride). These may be contained alone or in combination of two or more.

[0031] The (D) component mainly contributes to the disinfecting property of the cleaning composition of the present invention. Therefore, if the amount of the (D) component is too small, the disinfecting property may be insufficient. On the other hand, if the amount of the (D) component is too large, the foam retention may decrease. From this viewpoint, the content of component (D) in the cleaning composition is preferably from 0.1 to 5.0 mass%, more preferably from 0.3 to 4.0 mass%, and particularly preferably from 0.5 to 3.0 mass%.

[0032] The above-mentioned components (B) and (D) are preferably contained in such a ratio that the mass ratio of component (B) / component (D) is 0.002 or more and 50 or less. By adjusting the content within such a range, it is possible to improve the foam retention, rinsing properties, and disinfecting properties of the cleaning composition in a well-balanced manner. In particular, from the viewpoint of improving foam retention and / or rinsing properties, the lower limit of the (B) component / (D) component is preferably 0.002 or more, more preferably 0.05 or more, and even more preferably 0.1 or more. Also, from the viewpoint of maintaining sufficient disinfecting properties and / or storage stability, the upper limit of the (B) component / (D) component is preferably 50.0 or less, more preferably 10.0 or less, and even more preferably 2.0 or less.

By setting the pH in the above range, it is possible to exhibit good cleaning properties, disinfecting properties, and metal corrosion prevention properties in a well-balanced manner. More specifically, by setting the pH to 9 or more, it is possible to exhibit good cleaning properties and / or disinfecting properties, and by setting the pH to 14 or less, it is possible to exhibit good metal corrosion prevention properties.

[0035] The cleaning composition of the present invention may contain a chelating agent as a component (F) in addition to the above components (A), (B), (C), (D) and (E). By including the component (F), good aluminum corrosion prevention properties can be exhibited. Conventional highly alkaline cleaning agents have excellent cleaning properties against oil stains, but they do not provide sufficient protection against corrosion of metals such as aluminum. In contrast, the present invention, which includes the component (F), is applicable to the cleaning surfaces of various materials at beverage and food manufacturing sites and is highly versatile.

[0037] From the viewpoint of achieving high corrosion prevention properties, particularly for aluminum, it is preferable to include an aminocarboxylic acid chelating agent as component (F), and more preferably an alkanolamine salt of an aminocarboxylic acid chelating agent. Here, the alkanolamine refers to a compound having a hydroxyl group and an amino group in an alkane skeleton, and examples thereof include, but are not limited to, ethanolamine and propanolamine. Specific examples of alkanolamine salts of aminocarboxylic acid type chelating agents include, for example, alkanolamine salts of ethylenediaminetetraacetic acid, methylglycine diacetic acid, or glutamic acid diacetic acid, and more specific examples include, but are not limited to, sodium monoethanolamine salt of ethylenediaminetetraacetic acid.

[0038] When the component (F) is added, the amount of the component (F) can be appropriately determined while taking into consideration the amount of each component of the cleaning composition. From the viewpoint of more reliably exerting the corrosion inhibitory effect on aluminum, the content of the component (F) in the cleaning composition is preferably 0.1 mass% or more, more preferably 0.5 mass% or more, and particularly preferably 0.7 mass% or more.

The linear fatty acids and / or salts thereof may be contained as component (G) alone or in combination of two or more.

[0041] By including myristic acid and / or palmitic acid as the straight-chain fatty acid and / or its salt, better rinsing properties are exhibited.

[0042] When the (G) component is added, the amount of the (G) component can be appropriately determined while taking into consideration the amount of each component of the cleaning composition. From the viewpoint of more reliably exhibiting good rinsing performance, the proportion of the (G) component in the cleaning composition is preferably 0.01% by mass or more, more preferably 0.05% by mass or more, and particularly preferably 0.1% by mass or more. From the viewpoint of exerting sufficient rinsing performance while taking economical efficiency into consideration, the content of the (G) component in the detergent composition is preferably 3.0 mass% or less, more preferably 2.0 mass% or less, and particularly preferably 1.0 mass% or less. When the (G) component contains a fatty acid salt, the content of the (G) component in the detergent composition of the present invention is the content calculated from the amount of the fatty acid salt converted into fatty acid.
