However, from the viewpoint of significantly achieving the effects of the present invention, for example, a pH of 7.0 to 12.5 is preferred, a pH of 8.0 to 12.5 is more preferred, a pH of 8.5 to 12.5 is even more preferred, and a pH of 9.0 to 12.5 is particularly preferred. The pH is measured at room temperature (23° C.) using a pH meter (for example, pH METER F-52 (manufactured by HORIBA Corporation)).

[0072] [viscosity] The viscosity (25°C) of the cleaning composition according to the embodiment of the present invention can be appropriately set depending on the dosage form, etc. When used in a tube formulation, the viscosity is, for example, 100 to 2000 Pa·s, but is not limited thereto.

[0073] The viscosity (25°C) mentioned above is measured using a single-cylindrical rotational viscometer (Brookfield type viscometer) in accordance with the viscosity measurement method described in the General Test Methods of the 17th Edition of the Japanese Pharmacopoeia. Specifically, it refers to the value measured using a TV-10M (manufactured by Toki Sangyo Co., Ltd.), with the rotor, rotation speed, and other conditions selected in accordance with the instruction manual for this machine, and the viscosity measured at 25°C.

[0074] The single cylinder rotational viscometer is described below. A single cylinder rotational viscometer is a viscometer that measures the torque when a cylinder is rotated at a constant angular velocity in a liquid. By experimentally determining the instrument constant KB in advance using a standard liquid for viscometer calibration, the viscosity η of the liquid can be calculated using the following equation. η=KB×T / ω η: Viscosity of the liquid (mPa·s) KB: Equipment constant (rad / cm 3 ) ω: Angular velocity (rad / s) T: Torque acting on the cylindrical surface (10 -7 N·m)

[0075] <Usefulness of the present invention> The present invention was made in the course of researching formulation designs capable of improving squeak caused by higher fatty acids and / or their salts. The inventors focused on the combination of surfactants and cationic water-soluble polymers, among various raw materials, and discovered that squeak can be effectively improved by using a specific surfactant in combination with a specific cationic water-soluble polymer. Specifically, the cleaning composition according to an embodiment of the present invention is useful in that it can provide a cleaning composition that can reduce squeaking during and after cleaning by blending (A) a higher fatty acid and / or a salt thereof, (B) at least one surfactant selected from the group consisting of alkyl betaine, alkylamidopropyl betaine, and polyglyceryl alkyl ether, and (C) a cationic water-soluble polymer containing 35% or more cationic constituent units by molar ratio.

[0076] In particular, the present invention is particularly useful in that it can effectively improve squeakiness even under formulation conditions that result in increased squeakiness caused by higher fatty acids and / or salts thereof. For example, if a cleaning composition is formulated to contain a large amount of (A) higher fatty acid and / or its salt in order to improve its cleaning properties, the squeaking caused by the higher fatty acid and / or its salt tends to become stronger, making it more difficult to alleviate the squeaking. The cleaning composition according to the embodiment of the present invention is particularly useful in that it can provide a cleaning composition in which squeaking is sufficiently suppressed, even when formulated to contain a large amount of (A) higher fatty acid and / or its salt (for example, 15% by mass or more of the total amount of the cleaning composition). Furthermore, for example, if the pH of a cleaning composition is adjusted to an alkaline range in order to improve the cleaning properties of the cleaning composition, the cleaning composition tends to have a stronger squeaky sound, making it more difficult to alleviate the squeaky sound. The cleaning composition according to the embodiment of the present invention is particularly useful in that it can provide a cleaning composition in which squeaky sound is sufficiently suppressed, even when the pH is adjusted to an alkaline range (e.g., pH 7.0 to 12.5). Thus, the cleaning composition according to the embodiment of the present invention is particularly useful in that it can provide a cleaning composition that has high detergency and also has a high effect of reducing squeakiness (i.e., it simultaneously solves the conflicting problems of high detergency and an effect of reducing squeakiness). In particular, if the content of (A) higher fatty acid and / or its salt is 20 mass% or more of the total amount of the cleaning composition and the pH of the cleaning composition is 11.0 or more, it is even more useful in that it can provide a cleaning composition that has particularly excellent detergency and also has a high effect of reducing squeakiness.

[0077] Furthermore, the cleaning composition according to a preferred embodiment of the present invention is highly useful in that it not only has excellent cleaning properties and foaming properties, but also provides a refreshing feeling when used with reduced squeaking.

[0078] It is not entirely clear why the present invention can provide a cleaning composition with excellent squeaky-reducing effects. However, considering that the cause of squeaky sensation on the skin is thought to be soap scum formed by the combination of higher fatty acids with divalent metal ions such as calcium ions contained in tap water, it is presumed that the excellent squeaky-reducing effects are achieved by blending the (B) and (C) components of the present invention with higher fatty acids, which acts to inhibit the above-mentioned bonding and / or inhibits the aggregation of soap scum formed by the above-mentioned bonding.

[0079] [Form of formulation] The cleaning composition according to the embodiment of the present invention is prepared in various forms by blending the above-mentioned components and, if necessary, further components, according to a conventional method. The formulation form is not particularly limited, and may be any form such as body soap, hand soap, facial cleanser, shampoo, etc. Furthermore, it may be in the form of a cleanser, rinse-in shampoo, conditioner, etc. Furthermore, the cleaning composition according to the embodiment of the present invention may be in any form such as a liquid, gel, paste, etc.

[0080] [Application] The cleaning composition according to the embodiment of the present invention is preferably used as a skin cleansing composition or a hair cleansing composition, more preferably as a skin cleansing composition, and even more preferably as a face cleansing composition.

[0081] [container] The cleaning composition according to the present invention can be filled into a container appropriately selected depending on the intended use and application. Examples of such containers include bottles, tubes, jars, dispensers, pouches, and cheer packs. Materials for the container include polyethylene terephthalate, polypropylene, polyethylene (HDPE, LDPE, LLDPE, etc.), ABS resin, ethylene vinyl alcohol resin, polystyrene, glass, metal (aluminum, etc.), and mixtures thereof. Containers made from these materials can be coated with various coatings to improve strength, flexibility, weather resistance, or component stability. Containers can also be formed by laminating films made from the above materials.

[0082] <How to improve squeaks> In another embodiment of the present invention, the present invention is suitably provided as a method for improving squeaky sound during and / or after washing, characterized by blending into a cleaning composition (A) a higher fatty acid and / or a salt thereof, (B) at least one surfactant selected from the group consisting of alkyl betaine, alkylamidopropyl betaine, and polyglyceryl alkyl ether, and (C) a cationic water-soluble polymer containing 35% or more cationic constituent units by molar ratio.
