Description

[Technical field]

[0001] The present invention relates to a cleaning composition. [Background technology]

[0002] Cleansing agents, particularly skin cleansing agents, are required to have good foaming properties and good foam feel during cleaning. For example, Patent Document 1 describes that a skin or hair cleansing composition containing a surfactant and a cationic polymer has excellent foaming properties and a good feeling when used. Patent Documents 2 and 3 describe skin cleansing compositions that contain a glyceryl ether in addition to an anionic surfactant and a cationic polymer, and have good foam volume and quality, as well as good rinsing properties.

[0003] Meanwhile, skin cleansing agents filled in foam-dispensing containers have been developed in recent years because they eliminate the need for the effort of foaming. [Prior art documents] [Patent documents]

[0005] Skin cleansing agents filled in foam-dispensing containers are used by applying the foam dispensed from the container directly to the skin and spreading it over the skin with the hands. Therefore, there is an increasing demand for the foam dispensed from the former to be fine and maintain a consistent shape, for dense white foam to increase even in the latter half of the wash process, and for the cleansing properties to be good. [Means for solving the problem]

[0006] The inventors have discovered that by incorporating a specific amount of a polymer having a cationic group with a specific cationic charge density and a specific molecular weight into an ionic surfactant and an alkyl glyceryl ether, and filling the detergent into a foam-dispensing container and dispensing it as a foam, the discharged foam maintains a fine and consistent shape, dense white foam increases even in the latter half of the cleaning process, and cleaning properties are good.

[0007] The present invention comprises the following components (A), (B) and (C): (A) an ionic surfactant, (B) alkyl glyceryl ethers, and (C) A polymer having a cationic group with a cationic charge density of 4.5 meq / g or less and a molecular weight of 500,000 or less and a content ratio (B / C) of component (B) to component (C) is 1.5 or more, the cleaning composition being filled into a foam-dispensing container and dispensed as foam. Effect of the Invention

[0008] The cleansing composition of the present invention produces fine foam that maintains a consistent shape when applied to the skin after being discharged from a foam discharge container, and produces an increase in dense white foam even in the latter half of the cleansing process, while also exhibiting good cleansing properties.

For example, surfactants other than those mentioned above; lower alcohols such as ethanol and isopropyl alcohol; aromatic alcohols such as benzyl alcohol and benzyloxyethanol; cellosolves such as ethyl cellosolve and butyl cellosolve; carbitols such as ethyl carbitol and butyl carbitol; moisturizing components such as sugar (derivatives), amino acid (derivatives), animal and plant (protein) derivatives, and animal and plant extracts; silicone derivatives such as polyoxyalkylene-modified silicone; inorganic or organic salts such as sodium sulfate, sodium carbonate, sodium bicarbonate, potassium chloride, sodium chloride, and sodium citrate; pH adjusters such as acids and alkalis; anti-inflammatory agents such as glycyrrhetic acid, glycyrrhizic acid and derivatives thereof; bactericides such as isopropylmethylphenol; preservatives, sequestering agents, antioxidants, ultraviolet absorbers, anionic polymers, nonionic polymers, amphoteric polymers, fragrances, thickeners, vitamins, and colorants such as natural dyes and tar dyes.

[0059] The pH of the detergent composition of the present invention is not particularly limited, but considering its use for cleaning skin, it is preferably 5 to 9. In the present invention, the pH is measured by filling 100 mL of the liquid detergent composition (undiluted) into a beaker, adjusting the temperature to 30° C. in a thermostatic bath at 30° C., and then immersing a pH measurement electrode in the liquid detergent composition for 1 minute.

[0060] The cleaning agent composition of the present invention is in a liquid state, and from the viewpoint of ensuring the formability of a foam that maintains a certain shape and the dischargeability, the viscosity at 30°C is preferably from 2 to 20 mPa s, more preferably from 3 to 16 mPa s, and even more preferably from 3 to 15 mPa s. In the present invention, the viscosity is measured at 30° C. using a Brookfield viscometer (Toki Sangyo, TVB-10) with rotor No. 1 rotating at a rotation speed of 60 r / min, and the viscosity is measured 60 seconds after the start of rotation.

[0061] The cleaning agent composition of the present invention is preferably filled into a foam-discharging container (foamer container) and discharged as a foam from the foam-discharging container. The cleanser composition is a foam-discharging composition, and when discharged as a foam from a foam-discharging container, the foam when applied to the skin is fine and maintains a constant shape, and dense white foam increases even in the latter half of the cleansing process, producing a foam composition with good cleansing properties. The cleanser composition, together with the foam-discharging container, can constitute a skin cleanser. The volume ratio of air to composition (air / composition) when dispensed from the foam dispenser container is preferably 10 / 1 or more, more preferably 12 / 1 or more, and even more preferably 13 / 1 or more, from the viewpoint of further improving foam thickness, foam whiteness, and foamability.

[0062] The foam dispensing container used in the present invention is preferably, for example, an atmospheric pressure container having a container, a foaming mechanism, and a discharge port, which does not require a propellant such as compressed gas. The composition may be stored in a container, and the foaming mechanism may have a gas-liquid mixing section and a bubble finer section, generate foam from the liquid, and discharge the foam from a discharge port. The gas-liquid mixing section is a region where air transported from the outside or inside of the foam-dispensing container flows in and mixes with the liquid detergent composition that is filled in the container as the contents by being stored in a member such as the inside of the main body or a tank. The foam fine-making section is a region or member that fine-tunes the foam produced by mixing the air and the detergent composition by providing a flow path with a specific shape, a porous member, or the like in the flow path to the discharge port. The discharge port is a member that discharges to the outside the foam that is produced by mixing the air and the detergent composition and that has been fine-tuned by the foam fine-making section.

[0063] That is, the gas-liquid mixing section, the foam fine-making section, and the discharge port of these foam-discharging containers are linked directly or indirectly in this order, if necessary, via members such as a tube or a nozzle. Then, in response to the applied manual or electric power, the cleaner composition filled as a liquid inside the body of the foam-discharging container or in a member such as a tank passes from the gas-liquid mixing section to the foam fine-making section, and then from the foam fine-making section to the discharge port, and the cleaner composition in the form of fine bubbles containing embedded air is discharged from the discharge port to the outside and can be applied to the skin.

[0064] From the viewpoint of ensuring good foam quality while discharging foam at a high foaming ratio, the foam-discharging container used in the present invention has a mechanism for discharging the contents from a discharge port of the container, in which the volume ratio of air to cleaning composition (air / composition) is preferably 10 / 1 or more, more preferably 12 / 1 or more, and even more preferably 13 / 1 or more. The volume ratio of air to the cleaning composition (air / composition) refers to the value at 25°C. An example of a mechanism for discharging the contents from the outlet at the above-mentioned volume ratio (air / composition) of air and the skin cleanser composition is a gas-liquid mixing section that can mix air and the skin cleanser composition at the above-mentioned volume ratio (air / composition).

[0065] A specific form of the foam-discharging container may have a mechanism for discharging air and the cleaning agent composition from a gas-liquid mixing section in the above-mentioned mass ratio, optionally via a component such as a tube or a nozzle, and then discharging the contents to the outside from a discharge outlet, preferably after passing through a foam-refining section. Examples of the foam-discharging container include a squeeze-type container, a manual pump-type container, and an electric pump-type container.

[0066] The squeeze-type container is also called a squeeze container, and is a container in which a pressure is applied from the outside manually to a body part located in a deformable container body, that is, the body part is squeezed and deformed, so that air pumped from inside the head space is mixed with the liquid content in the gas-liquid mixing part to form bubbles, and then the bubbles are finely divided in the bubble finer part, and the bubbles are discharged from the discharge port.Specific examples include the containers described in JP-A-7-215353.

[0067] A pump type container is also called a pump container, and by pressing a pump head provided on a foam dispenser having a discharge port, air pumped from inside or outside the container and the liquid content are mixed in the gas-liquid mixing section to form foam, the foam is finely divided in the finely divided foam, and the foam is discharged from the discharge port. That is, such a pump type container is equipped with an air cylinder for introducing air from inside or outside the container and a liquid cylinder that serves as a flow path for the liquid content, and has a mechanism in which a piston slides inside each cylinder. Then, these pistons are driven by pressing the pump head, and the air and the liquid content are sent to the gas-liquid mixing section and mixed in the gas-liquid mixing section, and then foam is formed in the finely divided foam, and the foam is discharged from the discharge port. Containers of the so-called manual pump type, in which the pump head is pressed manually, and containers of the so-called electric pump type, in which the pump head is pressed manually and the air and the liquid content are transported between members, are electrically operated, and either type can be used. Specifically, for example, there are manual pump type containers described in JP 2009-202122 A and electric pump type containers described in JP 2006-212086 A and JP 2013-212244 A.

[0068] Among these specific forms of foam-dispensing containers, manual pump type containers and electric pump type containers are preferred from the standpoint of consistently ensuring a high foaming ratio, ensuring the formation of high-quality foam, and ease of operation of the container.

[0069] Furthermore, the foam dispensing container used in the present invention preferably has a mesh or a porous member with multiple small holes in the foam refinement section from the viewpoint of forming a good foam composition when the contents pass through the discharge port, and from the viewpoint of the formed foam having good foam quality and improving the feeling of use, etc. The mesh size is preferably 16 to 180 μm (#510 to #90), and considering the ease of use of the container and the obtained foam quality, 40 to 80 μm (#330 to #180) is more preferable.

[0070] The detergent composition of the present invention is preferably a skin detergent composition used for skin cleaning. For example, it can be suitably used as a hand soap, a face wash, or a body soap. The detergent composition of the present invention can be used to clean the skin by a general skin cleaning method. For example, the foam discharged from a foam discharge container is taken by hand, and directly applied to the skin as it is without diluting with water, and the foam is formed and cleaned, and then the skin is rinsed with warm water such as a shower. The cleaning method includes washing by hand and washing with cleaning tools including sponges, towels, scrubbing brushes, etc. made of chemical fibers such as cotton and nylon. From the viewpoint of reducing irritation to the skin, the method of directly taking the product into the hands and washing with the hands is preferable. EXAMPLES

[0071] The present invention will now be described in more detail with reference to examples, but the present invention is not limited to these examples.

[0072] Examples 1 to 21, Comparative Examples 1 to 7 Skin cleansing compositions were prepared having the compositions shown in Tables 1 to 3. The numerical values ​​for each component in the tables indicate the mass % of the active component (pure component) in the composition. Three expert panelists evaluated each of the obtained skin cleansing compositions for the following: foam state when dispensed from the foam-dispensing container, the amount of foam when the hands were wetted with water and the foam was dispensed from the foam-dispensing container with one push onto the palms of the hands and then the palms were rubbed together 20 times (amount of foam in the latter half of cleansing), the whiteness of the foam (whiteness of the foam in the latter half of cleansing), and the feel when rinsing. The results are shown in Tables 1 to 3. Each cleaning composition was filled into a pump foamer container (manufactured by Yoshino Kogyo Co., Ltd.) that was equipped with two meshes (#200 / mesh size 77 μm) in the foam-refining section and had a volume ratio (air / composition) of 13 / 1 in the gas-liquid mixing section, as a foam-discharging container.

[0073] (Manufacturing method) The skin cleansing composition was prepared by mixing and dissolving each component in water, and adjusting the pH of the skin cleansing composition to the value shown in the table with lactic acid, malic acid, and potassium hydroxide solutions. The obtained skin cleansing composition was filled into a foam discharge container.

[0074] (Evaluation method) (1) State of foam when discharged from the former: The foam was dispensed from the dispenser onto the palm of the hand, and whether the foam was fine and maintained a uniform shape was evaluated according to the following criteria. The results were shown as the average score of the three panelists. 5: Fine (no large air bubbles inside) and maintains a consistent shape 4: Slightly fine (1-5 large bubbles in the foam) and maintains a consistent shape 3: Slightly coarse (6-10 large bubbles in the foam) and maintains a consistent shape 2: Slightly coarse (more than 10 large bubbles in the foam) and maintains a consistent shape 1: Rough texture and no consistent shape

[0075] (2) Wet your hands with water, take one pump of foam, and rub your palms together 20 times to obtain the amount of foam (amount of foam after the second half of washing). One push of the foam discharged from the dispenser was taken into the hand, and the palms of the hands were rubbed together 20 times to collect all the foam, and the volume of the foam was measured using a liquid level meter (Kartell, cone type). The results were shown as the average (mL) of three subjects.

[0076] (3) Feeling when rinsing: One pump of the foam dispensed from the dispenser was taken into the hand, the palms of the hands were rubbed together 20 times, and the feeling when rinsing was evaluated according to the following criteria. The results are shown as the average score of the three panelists. If the average score is rounded to one decimal place, it can be evaluated that if it is 3 or more, the stickiness during rinsing is suppressed, and if it is 2 or less, the stickiness during rinsing is not suppressed. 5: Not sticky when rinsing 4: No sticky feeling when rinsing 3: Not sticky when rinsing 2: Slightly sticky when rinsing 1: Feels sticky when rinsing

[0077] (4) Wet your hands with water, take one pump, and rub your palms together 20 times to see how white the foam becomes: The foam dispensed from the dispenser was pumped into the hand, and the whiteness of the foam felt when the palms of the hands were rubbed together 20 times was evaluated according to the following criteria. The results were shown as the average score of three panelists. 5: The foam feels quite white 4: The foam feels white 3: The foam seems a little white 2: The foam doesn't seem very white 1: The foam doesn't seem white

[0078] As can be seen from Tables 1 and 2, when the skin cleansing composition of the present invention was applied to the skin after being dispensed from a foam dispenser container, the foam was fine and maintained a consistent shape, and even in the latter half of the wash, the amount of dense white foam increased, demonstrating good cleansing properties. On the other hand, the skin cleansing composition in Table 3 did not produce fine foam when applied to the skin, did not maintain a consistent shape, did not increase foam in the latter half of the cleansing process, and had insufficient cleansing properties.
