Summary of the Invention

Problems to be Solved by the Invention

[0004] In addition to the ability to effectively remove oil stains, the mildness to the skin of the hands is also important for the liquid detergent composition. Therefore, it is required that the liquid detergent composition can impart a feeling (moisturizing feeling) as if moisture remains on the skin of the hands after washing the tableware. However, in the conventional technology, the imparting of the moisturizing feeling has not been considered. In addition, if the stickiness to the skin of the hands increases too much in order to enhance the moisturizing feeling, it will give discomfort to the user. Therefore, an object of the present invention is to provide a liquid detergent composition for tableware that is excellent in detergency, suppresses stickiness, and is excellent in moisturizing feeling.

[0006] According to the liquid detergent composition for tableware of the present invention, it has excellent detergency, suppresses stickiness, and has excellent moisturizing feeling.

Modes for Carrying Out the Invention

[0007] (Liquid detergent composition for tableware) The liquid detergent composition for tableware (liquid detergent composition) of the present invention has components (A) to (E). In this article, "~" representing a range shall include its upper and lower limit values.

[0008] <Component (A)>[[]] (A) component is cationized cellulose. By containing the (A) component, the liquid detergent composition can impart a moisturizing feeling.

[0009] Examples of the (A) component include compounds represented by the following formula (a1) ((a1) component), compounds represented by the following formula (a2) ((a2) component), compounds represented by the following formula (a3) ((a3) component), etc. Examples of the (A) component include cation-modified hydroxyethyl cellulose such as hydroxytrimethylammonio propyl hydroxyethyl cellulose chloride and hydroxyethyl cellulose dimethyldiallylammonium chloride polymer. Among these, from the viewpoint of better improving the moisturizing feeling and further suppressing the sticky feeling, the (a1) component is preferred as the (A) component.

[0010] [Chemical formula]

[0011] [In formula (a1), t, u, and s are numbers representing the number of repetitions respectively.]

[0012] [Chemical formula]

[0013] [In formula (a2), v and w are numbers representing the number of repetitions respectively.]

[0014] [Chemical formula]

[0015] (a1) component has an average molecular weight of 10,000 to 10 million. (a2) component has an average molecular weight of 10,000 to 1 million. (a3) component has an average molecular weight of 10,000 to 1 million. The average molecular weight is the weight-average molecular weight measured by gel permeation method.

[0016] (A) component preferably has a cationization degree of 0.5 to 3.5% by mass, more preferably 1.5 to 2.5% by mass. When the cationization degree is within the above range, the moisturizing feeling can be enhanced more and the sticky feeling can be reduced more. Here, the "cationization degree" is the content rate (% by mass) of nitrogen atoms derived from the cationizing agent in the molecule of (A) component. That is, the cationization degree is the content rate of nitrogen atoms with respect to the total mass of (A) component. (A) component's cationization degree is calculated based on the specified chemical structure. When the ratio of any monomer in (A) component is unknown or the chemical structure of (A) component is not specified, the cationization degree of (A) component is calculated from the experimentally determined nitrogen content rate. Examples of the measurement method of the nitrogen content rate in (A) component include the Kjeldahl method.

The lower limit of the viscosity of a 1% by mass aqueous solution of component (A) at 25°C is preferably 100 mPa·s or more, more preferably 200 mPa·s or more. When the viscosity of a 2% by mass aqueous solution or a 1% by mass aqueous solution of component (A) is below the above upper limit, the stickiness can be further reduced. When the viscosity of a 2% by mass aqueous solution or a 1% by mass aqueous solution of component (A) is above the above lower limit, the moisturizing feeling can be further enhanced.

[0018] The viscosity is the value measured with a B-type viscometer for the measurement target (aqueous solution of component (A)) at 25°C. The measurement conditions for the viscosity are as follows.

The above-mentioned component (A) may be used alone or in combination of two or more.

[0021] The content of the component (A) is preferably 0.1 to 0.6% by mass, more preferably 0.2 to 0.6% by mass, and even more preferably 0.2 to 0.4% by mass based on the total mass of the liquid detergent composition.

[0033] m is preferably from 8 to 10, more preferably from 9 to 10. If m is within the above range, the stickiness (stickiness property) can be more suppressed. Here, m indicates the average repeating number of EO. Therefore, the component (C) may be a compound with a single repeating number of EO or an aggregate of molecules with different repeating numbers of EO.

[0034] j and k are each an integer from 1 to 6, and 6 ≤ j + k ≤ 12.

When the content of the component (C) is at least the above lower limit value, the stickiness can be further reduced. When the content of the component (C) is at most the above upper limit value, the detergency can be further enhanced.

[0036] <Component (D)> The component (D) is an anionic surfactant excluding soap (so-called non-soap anionic surfactant). By including the component (D) in the liquid detergent composition, the detergency can be enhanced. Soap is a higher fatty acid salt described later.

[0048] <(E) component> The component (E) is at least one selected from semi-polar surfactants and amphoteric surfactants. By containing the component (E) in the liquid detergent composition, a moisturizing feeling can be imparted and the stickiness can be reduced.

[0049] Note that the "semi-polar surfactant" refers to a surfactant having a semi-polar bond (a bond having properties intermediate between non-polar and polar bonds), and depending on the pH of the solution in which the semi-polar surfactant dissolves or the dispersion system in which it is dispersed, it becomes cationic or non-ionic.

These (e2) components may be used alone or in combination of two or more.

[0054] As the (E) component, only the (e1) component, only the (e2) component, or a combination of the (e1) component and the (e2) component may be used. As the (E) component, the (e1) component is preferred.

[0055] The content of the (E) component is preferably 2 to 10% by mass, more preferably 3 to 8% by mass, based on the total mass of the liquid detergent composition. When the content of the (E) component is at least the above lower limit value, the sticky feeling can be further reduced. When the content of the (E) component is at most the above upper limit value, the moisturizing feeling can be further enhanced.

[0056] (Mixing ratio) It is represented by the (B) component / (C) component, and the mass ratio (B / C ratio) of the content of the (B) component to the content of the (C) component is 1.0 to 3.0, preferably 1.0 to 2.0. When the B / C ratio is at least the above lower limit value, the amount of the complex of the (A) component and the (B) component can be reduced, so the sticky feeling can be reduced. When the B / C ratio is at most the above upper limit value, the amount of the complex of the (A) component and the (B) component increases, and the moisturizing feeling can be further enhanced.

[0057] The total of the content of the (B) component and the content of the (C) component is defined as the BC amount. It is represented by ((Component (B) + Component (C)) / Component (A)), and the mass ratio of the amount of BC to the content of Component (A) (BC / A ratio) is from 10 to 50, preferably from 15 to 30, more preferably from 15 to 25. When the BC / A ratio is at least the above lower limit value, the sticky feeling can be further reduced. When the BC / A ratio is at most the above upper limit value, the moisturizing feeling can be further enhanced.

[0058] The total amount of the contents of Component (B), Component (C), Component (D) and Component (E) (BCDE amount) is from 10 to 20% by mass, preferably from 15 to 20% by mass, based on the total mass of the liquid detergent composition. When the BCDE amount is at least the above lower limit value, the sticky feeling is reduced and the detergency can be enhanced. When the BCDE amount is at most the above upper limit value, the moisturizing feeling can be enhanced.

[0059] The total amount of Component (D) and Component (E) (DE amount) is preferably from 5 to 15% by mass, more preferably from 7 to 12% by mass. When the DE amount is at least the above lower limit value, the detergency can be further enhanced. When the E amount is at most the above upper limit value, the moisturizing feeling can be further enhanced.

[0060] It is represented by Component (D) / Component (E), and the mass ratio of the content of Component (D) to the content of Component (E) (D / E ratio) is preferably from 0.7 to 1.3. When the D / E ratio is at least the above lower limit value, the proportion of the complex of Component (D) and Component (E) increases and the amount of Component (D) present as a single entity decreases. For this reason, the inhibition of the adsorption of the complex of Component (A) and Component (B) to the hand skin is reduced, and while the moisturizing feeling is further enhanced, the detergency can be further enhanced. When the D / E ratio is at most the above upper limit value, the proportion of the complex of Component (D) and Component (E) increases and the amount of Component (E) present as a single entity decreases. For this reason, the inhibition of the adsorption of the complex of Component (A) and Component (B) to the hand skin is reduced, and while the moisturizing feeling is further enhanced, the detergency can be further enhanced.

[0061] <Optional component> The liquid detergent composition may contain optional components other than components (A) to (E). Examples of the optional components include surfactants other than components (B) to (E) (optional surfactants), hydrotropes, preservatives, inorganic builders, hydrotropes, fragrances, pH adjusters, water, dyes, and the like. Note that the total of components (A) to (E) and the optional components does not exceed 100% by mass.

[0062] ≪Optional surfactant≫ Examples of the optional surfactant include cationic surfactants and nonionic surfactants other than component (B) and component (C).

[0063] The liquid detergent composition may contain one or more selected from higher fatty acids (fatty acids having 8 to 22 carbon atoms) and their salts (i.e., soaps). Examples of the higher fatty acid salts include alkali metal salts, alkaline earth metal salts, alkanolamine salts, ammonium salts, and the like.

Examples of the alkanolamine salts include monoethanolamine salts (monoethanolamine), diethanolamine salts (diethanolamine), triethanolamine salts (triethanolamine), and the like. Among them, as the higher fatty acid salt, an alkali metal salt is preferable, and a sodium salt or a potassium salt is more preferable. The content of the higher fatty acid or its salt is preferably 0 to 1% by mass, more preferably not contained, based on the total mass of the liquid detergent composition.

[0064] The total amount of surfactants including components (B) to (E) and the optional surfactant (excluding higher fatty acids or their salts) is preferably 10 to 20% by mass, more preferably 15 to 20% by mass, based on the total mass of the liquid detergent composition.

[0065] ≪Hydrotrope≫ By containing a hydrotrope, the storage stability (especially low-temperature stability) of the liquid detergent composition is mainly enhanced. As a result, the liquid detergent composition can more stably ensure a transparent appearance. Examples of the hydrotrope include toluenesulfonic acid, toluenesulfonate, cumenesulfonic acid, cumenesulfonate, ethanol, and the like. The hydrotrope may be used alone or in combination of two or more. In the hydrotrope, toluenesulfonic acid, toluenesulfonate, cumenesulfonic acid, and cumenesulfonate may each be any of the three isomers of the o-form, m-form, and p-form. Among these, the p-form is preferred because it is easily available, and among them, p-toluenesulfonic acid and p-toluenesulfonate are more preferred. The content of the hydrotrope is preferably 2 to 30% by mass, more preferably 3 to 10% by mass, based on the total mass of the liquid detergent composition. If the content of the hydrotrope is within the above range, the compounding effect can be sufficiently obtained without reducing the moisturizing feeling and detergency.

[0066] ≪Preservative≫ By containing a preservative in the liquid detergent, the growth of bacteria is suppressed even if microorganisms or the like are mixed into the liquid detergent. Examples of the preservative include isothiazoline-based compounds. Specifically, benzisothiazolinone (1,2-benzisothiazolin-3-one), methylisothiazolinone (2-methyl-4-isothiazolin-3-one), butylbenzisothiazolinone, chloromethylisothiazolinone, octylisothiazolinone, dichlorooctylisothiazolinone, and the like can be mentioned. The preservative may be used alone or in combination of two or more. The content of the preservative is preferably 0.0002 to 0.01% by mass (2 to 100 ppm) based on the total mass of the liquid detergent composition. If the content of the preservative is within the above range, the compounding effect can be sufficiently obtained while maintaining the detergency.

[0067] <<pH Adjusting Agent>> Examples of the pH adjusting agent include inorganic alkali agents, organic alkali agents, and the like. Examples of the inorganic alkali agent include sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, and the like. Among these, hydroxides such as sodium hydroxide and potassium hydroxide are preferable because they can further enhance the storage stability of the liquid detergent composition. Examples of the organic alkali agent include amine compounds such as monoethanolamine, diethanolamine, triethanolamine, N-methylpropanol, 2-amino-2-methyl-1-propanol, N-(β-aminoethyl)ethanolamine, diethylenetriamine, morpholine, and N-ethy morpholine. Among these, monoethanolamine is preferable because it can further enhance the storage stability of the liquid detergent composition. When the pH of the liquid detergent composition is too high, acids such as inorganic acids such as hydrochloric acid and sulfuric acid, and carboxylic acids such as acetic acid and citric acid may be used as the pH adjusting agent.

[0068] <<Fragrance>> As the fragrance, those usually used in liquid detergent compositions can be applied. Examples of the fragrance include the formulated fragrance compositions 1 to 4 described in Tables 1 to 8 of JP-A-2020-132680.

[0069] <<Water>> Examples of the water include ion-exchanged water, pure water, and the like. The content of water is preferably 70 to 98% by mass based on the total mass of the liquid detergent composition.

[0070] <Physical Properties> The pH of the liquid detergent composition at 25°C is preferably 6 to 8. If the pH of the liquid detergent at 25°C is within the above range, the moisturizing feeling and detergency can be further enhanced, and the stickiness can be further reduced. In the present invention, the pH (25°C) of the liquid detergent composition indicates a value measured by a method conforming to JIS Z 8802:2011 "pH Measurement Method". The pH of the liquid detergent composition can be adjusted using the pH adjuster described above.

[0071] The viscosity (at 25°C) of the liquid detergent composition is preferably from 1.0 to 150 mPa·s, more preferably from 1.0 to 100 mPa·s. When the viscosity is within the above range, the handling of the liquid detergent composition is easier.

[0072] (Manufacturing method) The liquid detergent composition of the present invention can be produced, for example, by dissolving the above-described components (A), (B), (C), (D) and (E) and optional components, if necessary, in water and adjusting the pH to a predetermined value using a pH adjuster.

[0073] (Usage method) As a method of using the liquid detergent composition (a method of cleaning tableware etc.), for example, there is a method of applying the liquid detergent composition to a cleaning tool, foaming the liquid detergent composition with this cleaning tool, and scrubbing the object to be cleaned (tableware etc.) with the foamed cleaning tool. Alternatively, there is a method of dissolving the liquid detergent composition in water to make a cleaning liquid, immersing the object to be cleaned in the cleaning liquid, and scrubbing with a cleaning tool. In any method, the object to be cleaned after scrubbing is rinsed with water, and then the object to be cleaned is drained.

[0074] Examples of the cleaning tool include sponges such as single-layer sponges, sponge scrubbers, and net sponges.

[0075] Examples of the object to be cleaned include ceramics and metal utensils. Examples of ceramics include tableware such as plates, bowls, and rice bowls. Examples of metal utensils include tableware such as forks and spoons, and stainless steel sinks.

[0076] Examples of the object to be washed include tableware such as plates, chopsticks, and spoons, cooking utensils such as pots, knives, and cutting boards, kitchen utensils such as ranges and stoves, and sinks. In this specification, these are collectively referred to as "kitchenware".

[0077] Although the effects of the present invention are not clear, they are presumed as follows. The (A) component and the (B) component form something like a complex due to structural similarity, and at that time, while taking in water molecules, they are expressed by adsorbing to the hand skin by the cationic group of the (A) component. If only such an action is involved, it will give a sticky feeling to the hand skin. In the present invention, since the (C) component is contained and the specific B / C ratio is present, the amount of the complex is such that the sticky feeling is reduced and a moisturizing feeling can be obtained. In addition, since the amounts of BCDE are within a specific range, the moisturizing feeling and detergency can be enhanced and the sticky feeling can be reduced. Furthermore, since the BC / A ratio is within a specific range, the adsorption amount of the complex to the fingers is set within an appropriate range, reducing the sticky feeling and imparting a moisturizing feeling.

[0088] <Evaluation criteria for stickiness> 5 points: There is absolutely no feeling of oil remaining on the hands (stickiness). 4 points: There is almost no feeling of oil remaining on the skin of the hands (stickiness). 3 points: There is not much feeling of oil remaining on the hands (stickiness). 2 points: There is a slight feeling of oil remaining on the hands (stickiness). 1 point: I feel like there is a strong oily feeling remaining on my hands (sticky feeling).

[0089] <Cleaning power> <Preparation of oil stains> As oil stains, solid tallow (manufactured by Wako Pure Chemical Industries, Ltd.) and Sudan IV (manufactured by Kanto Chemical Co., Ltd.) were mixed to prepare colored tallow (colored tallow). The concentration of Sudan IV in the colored tallow was set to 1% by mass.

[0090] <Creating a dirt model> 1 g of the colored beef tallow was applied evenly to the entire inside surface of a plastic container (product name: Neo Keeper, manufactured by Iwasaki Industries Co., Ltd.) measuring 10 cm in length × 15 cm in width × 5 cm in height, and this was used as a dirt model.

[0091] <Cleaning test> A sponge for dishwashing with a length of 11.5 cm, a width of 7.5 cm, and a height of 3 cm (trade name: Scotch-Brite, manufactured by Sumitomo 3M Limited) was taken, and 38 g of tap water and 2 g of the liquid detergent composition of each example were respectively taken, kneaded by hand 10 times, and then scrubbed. Specifically, with the sponge containing tap water and the liquid detergent, the inner bottom surface of the above-mentioned dirt model was scrubbed 10 times, the inner surface was scrubbed 1 time, and the four inner corners were scrubbed 5 times, and then rinsed with tap water.

[0092] ≪Evaluation of detergency against oil stains≫ After scrubbing, the degree of removal of oil stains on the inner surface of the container was evaluated. Such evaluation was carried out based on the following evaluation criteria (5-level evaluation) and regarded as the evaluation of detergency against oil stains. Three people evaluated this, and the average score was taken as the evaluation result.

[0093] ≪Evaluation criteria for detergency≫ 5 points: All dirt has fallen off. 4 points: Almost all dirt has fallen off. 3 points: Dirt has fallen off. 2 points: A little dirt has fallen off. 1 point: No dirt has fallen off.

[0094] (Examples 1 to 32, Comparative Examples 1 to 9) According to the compositions shown in Tables 1 to 7, components (A) to (E) and optional components were added to water and mixed to prepare the liquid detergent compositions of each example. In addition, the compounding amounts in the tables are values converted to pure components. The "appropriate amount" of the compounding amount is the amount necessary to adjust the liquid detergent composition to the pH in the table, and the "balance" is the remainder necessary to make the liquid detergent composition 100% by mass. Also, "-" in the compounding amounts in the tables indicates that the component is not compounded. For the liquid detergents of each example, the moisturizing feeling, stickiness, and detergency were evaluated, and the results are shown in the tables.
