Abstract
Description
[Technical field]
[0001] The present invention relates to a liquid bathroom cleaner composition. [Background technology]
[0002] A wide variety of dirt is present in a bathroom, including limescale, sebum, limescale, mold, etc. Various cleaning compositions have been proposed so far for removing dirt in the bathroom. For example, Patent Document 1 discloses a hard surface cleaner composition that contains a surfactant including a non-soap anionic surfactant, a glycol solvent, and an aminocarboxylic acid type chelating agent, and has a pH of 10 to 12. This cleaner composition has excellent cleaning power against limescale stains adhering to glass fiber reinforced plastic (FRP) surfaces. Furthermore, Patent Document 2 discloses a composition that contains a glycol solvent and an amine surfactant and thereby enhances the ability to clean sebum adhering to a glass surface.

[0003] [Patent Document 1] JP 2016-124965 A [Patent Document 2] JP 2020-105322 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, sebum stains are more difficult to remove when they adhere to a highly hydrophobic surface such as PP (polypropylene) resin than to a highly hydrophilic surface. Therefore, when sebum stains adhere to a bathtub lid made of PP (polypropylene) resin, it may be difficult to remove them using the cleaning compositions of Patent Documents 1 and 2. In order to improve the cleaning power against sebum stains, it is conceivable to increase the amount of anionic surfactant blended, but if the amount of anionic surfactant blended is too high, the problem of poor rinsing ability arises. Therefore, an object of the present invention is to provide a liquid cleaning composition for bathrooms that can achieve both improved cleaning power against sebum stains adhering to hydrophobic surfaces such as PP resin and improved rinsing properties. [Means for solving the problem]
[0005] In order to achieve the above object, the present invention employs the following configuration.

In addition, the content of a component that can be in the form of an acid or a salt is the content in the form of an acid, unless otherwise specified.
[0008] <Component (A)> Component (A) is a non-soap anionic surfactant. A "non-soap anionic surfactant" is an anionic surfactant other than higher fatty acids or their salts (so-called soaps). A "higher fatty acid" is a saturated or unsaturated fatty acid having 8 to 24 carbon atoms. In other words, component (A) is an anionic surfactant other than saturated or unsaturated fatty acids having 8 to 24 carbon atoms or their salts. Component (A) is used to provide effective cleaning power against limescale, sebum, and other stains that build up in the bathroom.
[0009] Examples of component (A) include alkylbenzenesulfonates, alkanesulfonates, alkyl sulfates, alkyl polyoxyethylene sulfates, α-olefinsulfonates, internal olefinsulfonic acids or salts thereof having a carbon-carbon double bond at the second or higher position (inside), alkylphenoxyphenyl disulfonates, fatty acid salts excluding higher fatty acid salts, α-sulfofatty acid salts, ether carboxylates, alkyl phosphates, alkyl polyoxyethylene phosphates, dialkyl sulfosuccinate salts, alkyl sulfosuccinate salts, alkenylsuccinates, N-acylamino acid salts, and N-acylmethyltaurine salts.
[0010] Among them, alkylbenzenesulfonates and α-olefinsulfonates are preferably selected from the viewpoint of excellent detergency, and α-olefinsulfonates are particularly preferred. Examples of the salt include alkali metal salts such as sodium salts and potassium salts, and alkanolamine salts such as monoethanolamine salts and diethanolamine salts. Among them, alkali metal salts such as sodium salts and potassium salts are preferred.
[0011] The component (A) may be used either as a single type alone, or as a suitable combination of two or more types. The content of component (A) is preferably 0.5 to 5.0 mass%, and more preferably 0.5 to 1.5 mass%, based on the total mass of the bathroom liquid cleaner composition. A content of 0.5 mass% or more enhances cleaning power, while a content of 5.0 mass% or less improves rinsing ability.

[0021] The degree of cationization of component (B) can be calculated based on the identified chemical structure. When the ratio of the constituent units in component (B) is unknown, or when the chemical structure of component (B) is not identified, the degree of cationization of component (B) is calculated from the nitrogen content determined experimentally.

When the viscosity of a 2% by mass aqueous solution of component (B) is within the above range, the bathroom liquid cleaning composition will have excellent water-draining properties when rinsed with running water from a shower, etc., and the concentration of the composition will become low. The viscosity is a value measured using a Brookfield viscometer for a 2% by mass aqueous solution of component (B) at 25° C. The viscosity measurement conditions are as follows:

After that, the dirty board was taken out and the state of dirt removal was visually observed and evaluated according to the following evaluation criteria. In the following evaluation criteria, a score of ◯ or higher indicates good practical cleaning power for sebum stains.
[0065] Evaluation criteria ◎: Dirt removal is very good. 〇: Dirt removal is good. △: Dirt removal is uneven. ×: Almost no dirt is removed.
[0066] [Rinseability evaluation] Each example of the bathroom liquid cleaning composition was filled into a trigger container of the commercially available bathroom cleaner "Ofuro no Look" and sprayed 10 times at equal intervals into the inside of an FRP bathtub (100 x 75 x 65 cm). Then, using a urethane sponge, spray the inside of the bathtub with approximately 10 g / cm 2 The entire inside surface of the bathtub was rubbed in a circular motion while applying a load of 0.01 kg, and then the bathtub was rinsed with tap water from a shower (water temperature 15°C, flow rate 0.2 L / sec). The time until the foam completely disappeared from the bathtub drain was measured, and the rinsing ability of the bathroom liquid cleaner composition was evaluated according to the following evaluation criteria. In the following evaluation criteria, ◎ and ○ were considered to be acceptable.
[0067] Evaluation criteria. ◎: 19 seconds or less. ○: More than 20 seconds but less than 23 seconds. △: Between 23 and 30 seconds. ×: More than 31 seconds.

[0072] [Table 5]
[0073] As shown in Tables 1 to 4, all of Examples 1 to 24 were excellent in sebum cleansing power and rinsing ability. In contrast, as shown in Table 5, Comparative Example 1 not containing component (B) and Comparative Example 2 not containing component (C) had insufficient sebum cleansing power. Moreover, in Comparative Examples 3 and 4, in which the ratio [(B) / (C)] was outside the range of 0.1 to 4.0, the sebum cleansing power was insufficient, and in Comparative Example 4, the rinsing performance was also insufficient.
