Description

[Technical field]

[0001] The present invention relates to a composition containing powder, and more particularly to a composition having excellent powder settling-inhibiting properties and a method for inhibiting powder settling. [Background technology]

[0002] Various powders are widely used as components that exhibit desired functions or benefits in various fields such as cosmetics, quasi-drugs, medicines, paints, etc. For example, powders such as activated carbon (e.g., medicinal carbon) and kaolin are blended in face washes and the like for the purpose of absorbing or removing sebum and dirt, and powders such as titanium oxide are blended in various cosmetics and the like for the purpose of ultraviolet protection, coloring, etc.

[0003] On the other hand, various powders blended into compositions such as cosmetics tend to aggregate and settle over time. Therefore, from the viewpoint of effectively expressing the functions and benefits derived from the powder and maintaining its quality, it is important to suppress the settling of the powder and increase its stability over time.

[0004] Various techniques for suppressing powder settling have been proposed, such as a method of coating the powder surface with various resin components, a method of blending a thickener with a high yield value, etc. Specifically, for example, Patent Document 1 proposes blending a thickener such as xanthan gum or succinoglycan into a cosmetic preparation in order to suppress powder settling.

[0005] [Patent Document 1] International Publication No. 2019 / 168003 Summary of the Invention [Problem to be solved by the invention]

[0006] The present inventors have mainly conducted research into the method of blending thickeners such as water-soluble polymers, because the above-mentioned method of coating the surface of the powder may result in the loss of the powder's properties. In the course of such research, the present inventors have learned that blending thickeners with high yield values, which have been widely used to suppress powder settling, may not be able to sufficiently suppress powder settling over time, and that there is room for further research. [Means for solving the problem]

[0007] In order to solve the above problems, the present inventors conducted further research focusing on the properties of thickeners such as water-soluble polymers, the properties of surfactants, and the properties of powders that are prone to settling. As a result, they unexpectedly discovered that by using a specific water-soluble polymer and a specific surfactant, and by controlling the average particle size of the powder within a specific range, it is possible to provide a composition that is excellent in inhibiting the settling of powder.

[0008] That is, the present invention provides the following.

[3] The composition according to [2], wherein the (D) cationic polymer is a dimethyldiallylammonium chloride-acrylamide copolymer and / or O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride.

[5] The composition according to any one of [1] to [4], wherein the anionic surfactant (B) is a salt of a higher fatty acid having 12 to 22 carbon atoms.

Specifically, it is a value measured using a TV-10M (manufactured by Toki Sangyo Co., Ltd.), and the selection of conditions such as the rotor and rotation speed is in accordance with the instruction manual for this machine, and the viscosity is measured at 25°C.

[0097] The single cylinder rotational viscometer is described below. The single cylinder rotational viscometer is a viscometer that measures the torque when a cylinder in a liquid is rotated at a constant angular velocity. The device constant KB is experimentally determined in advance using a standard liquid for calibrating the viscometer, and the viscosity η of the liquid is calculated using the following formula. More specifically, it can be determined under the conditions described in the Examples. 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)

[0098] Although it is usually difficult to suppress sedimentation in a composition with a relatively low viscosity, the present composition is useful in that it can provide a composition with excellent sedimentation suppression properties despite its relatively low viscosity. Therefore, for example, a composition containing components (A) to (C) can provide a stable composition with excellent sedimentation suppression properties even if it has a low viscosity of, for example, 1 to 10 Pa·s, and is therefore particularly useful in that it can provide a cleaning composition with a good initial foaming speed.

[0099] [pH of composition] The pH of the present composition can be appropriately set depending on the dosage form, etc., and is not limited to, for example, pH 4 to 13, pH 4 to 12, pH 5 to 11.5, pH 5.5 to 11, etc. Among these, from the viewpoint of significantly exhibiting the effects of the present invention and from the viewpoint of improving the cleaning properties when used as a cleaning composition, a pH of 5 to 13 is preferable, a pH of 5.5 to 12 is more preferable, a pH of 6 to 11.5 is even more preferable, a pH of 8 to 11.5 is even more preferable, and a pH of 9 to 11 is particularly preferable. The pH is measured using a pH meter (for example, pH METER F-52 (manufactured by HORIBA) at room temperature (23° C.)).

[0100] In addition, in the past, it was particularly difficult to find a formulation design that can enhance the settling inhibition of powders in compositions in which the pH range of the composition is set in the alkaline range, such as soap-based cleaning compositions containing higher fatty acid salts. The present composition is very useful in that it can provide a composition with excellent settling inhibition even when the pH range of the composition is set in the alkaline range by using the components (A) to (C) in combination. Specifically, for example, a composition with excellent settling inhibition can be provided even in compositions such as pH 8 or more, pH 8.5 or more, pH 9 or more, pH 9.5 or more, or pH 10 or more, so that it is very useful in that it can provide a cleaning composition with excellent cleaning properties (especially sebum cleaning properties). Furthermore, a cleaning composition in the above pH range is also useful in that precipitation is suppressed and it is excellent in stability.

[0101] [Dosage form and formulation of the composition] The composition is prepared in various forms by blending the above-mentioned components and, if necessary, further components, according to a conventional method. The composition is provided in any form that can be widely used as cosmetics, quasi-drugs, medicines, foods, paints, various resin compositions, etc. Among these, cosmetics, quasi-drugs, and medicines are preferred. The composition is provided as, for example, a wipe-off type sheet such as a lotion, gel, mousse, liquid, suspension, emulsion, cream, ointment, gel, liniment, or a facial sheet or body sheet in which the composition is impregnated into a sheet such as a nonwoven fabric, etc. Depending on the formulation, an oil-in-water type (O / W), water-in-oil type (W / O), etc., can be appropriately selected according to the purpose of use and the desired feeling when used, but an oil-in-water type (O / W) composition is preferred.

[0102] [Method of manufacturing the present composition] The composition can be produced by a known method, for example, by mixing the components according to or in accordance with the General Provisions of the Japanese Pharmacopoeia, 18th Edition.

[0103] [Container of the composition] The composition can be filled into a container appropriately selected according to the purpose and application of use and used. Examples of the container include bottle-type, tube-type, jar-type, dispenser-type, pouch bag, and spout-equipped pouch. Examples of materials constituting the container include polyethylene terephthalate, polypropylene, polyethylene (HDPE, LDPE, LLDPE, etc.), ABS resin, ethylene vinyl alcohol resin, polystyrene, glass, and metal (aluminum, etc.), and mixtures thereof. In addition, containers formed from these materials can be subjected to various coating treatments on the container surface, for example, in consideration of strength, flexibility, weather resistance, or stability of components. In addition, containers can be formed by laminating films formed from the above materials.

[0104] [Applications, etc.] The use of the present composition is not particularly limited, but it is preferably used as a composition for external use, and specific examples thereof include basic cosmetics such as serum, lotion, sunscreen cream, milky lotion, cream, lotion, oil, and pack; makeup cosmetics such as foundation, lipstick, lip balm, mascara, eye shadow, eyeliner, eyebrow ink, and nail polish; and cleansing products such as cleansing products. Among these, it is preferably used as a cleansing product (cleaning composition). Specifically, it is preferably provided as a body soap (also called a body shampoo), a hand soap, a facial wash, a cleansing product for removing makeup, a hair shampoo, a dry shampoo, a rinse-in shampoo, and the like.

[0105] That is, the present composition is preferably used as a cleaning composition to be applied to the skin (including the face, body, and scalp) or hair, more preferably as a skin cleaning composition, and particularly preferably as a cleaning composition for the face and / or body. In one embodiment of the present invention, from the viewpoint of excellent cleansing properties, particularly excellent sebum cleansing properties, the composition is suitable as a skin cleansing composition to be used on any of the areas where sebum is actively secreted, such as the face, back, abdomen, chest, inside of joints, etc., and is suitable as a cleansing composition for sebum cleaning or as a sebum cleanser. It is also suitable as a cleansing composition for oily skin, which tends to secrete excess sebum.

[0106] <Methods to prevent powder settling, etc.> One embodiment of the present invention is a method for improving the stability of a composition by allowing (A) an (acrylates / alkyl acrylate (C10-30)) crosspolymer, (B) an anionic surfactant, and (C) a powder having an average particle size of 0.05 to 500 μm to coexist in the composition.

[0110] Cleaning compositions having the formulations shown in Tables 1 to 3 were prepared by a conventional method and evaluated as follows. The viscosities of the cleaning compositions having the formulations shown in Tables 1 to 3 were measured by the following method.

[0111] <Stability: Powder settling test 1> 50 g of the cleaning composition was filled into a 50 ml glass screw vial and stored at 50° C. for 2 months, after which the presence or absence of settling of the charcoal (medicinal charcoal) was visually confirmed. The results were evaluated according to the following criteria and are shown in Table 1. (Evaluation Criteria) ○: No charcoal settling. ×: Charcoal settling is observed.

[0112] <Stability: Powder settling test 2> 50 g of the cleaning composition was filled into a 50 ml glass screw vial and stored at 50° C. for one month, and the presence or absence of precipitation of kaolin or silicic anhydride (silica) was visually confirmed. The results were evaluated according to the following criteria and are shown in Table 3. (Evaluation Criteria) ○: No settling of powder. ×: Settling of powder observed.

[0113] <Stability: Low temperature precipitation test> 50 g of the cleaning composition shown in Table 1 containing charcoal (medicinal charcoal) was filled into a 50 ml glass screw vial and stored at 4°C for 2 months, and the presence or absence of precipitation was visually confirmed. The results were evaluated according to the following criteria and are shown in Table 1. (Evaluation criteria) ○: No precipitation. ×: Precipitation is observed.

[0114] <Cleaning ability: Rinseability (sliminess) test> 0.5 g of the cleaning composition was applied to the inside of the forearm of a specialist panelist, and after lathering with the fingers for 10 seconds, the composition was rinsed with tap water while rubbing with the palm of the hand. Rinsing performance was evaluated based on the number of times the composition was rubbed with the palm of the hand (1 time = 1 back and forth) until the stickiness disappeared. The results are shown in Tables 1 to 3. (Evaluation Criteria) ○: Rub with palm 9 times or less until stickiness disappears. ×: Rub with palm more than 10 times until stickiness disappears.

[0115] <Cleaning ability: Foaming test> A panel of experts took 0.5g of the cleaning composition onto a face washing net that had been thoroughly wetted with water, and rubbed it with both hands wearing rubber gloves to create a lather. The state in which the gel-like cleaning composition had completely turned into a lather was considered to be sufficient lather, and the lathering ability was evaluated based on the number of times the face washing net was rubbed with both hands until sufficient lather was created. The results are shown in Tables 1 to 3. (Evaluation Criteria) ○: The facial cleansing net was rubbed with both hands less than six times until sufficient lather was produced. ×: The facial cleansing net was rubbed with both hands more than 7 times until sufficient lather was produced.

[0116] <Method of measuring viscosity> 50 g of the cleaning composition was filled into a 50 ml glass screw vial and allowed to stand at room temperature (25° C.) for 1 day (24 hours), after which the viscosity was measured under the following conditions using a B-type viscometer (manufactured by Toki Sangyo Co., Ltd.). Rotor: M3 Rotation speed: 12 rpm Measurement time: 60 seconds ·Measurement temperature: 25℃

[0118] [Table 2]

[0119] [Table 3]

[0120] As shown in Tables 1 to 3, it was confirmed that in the cleaning composition of the present invention containing components (A), (B), and (C), the powder of component (C) did not settle even after storage at 50°C for 2 months. On the other hand, in the cleaning compositions containing a thickener other than the component (A), the component (B), and the component (C) as in each of the comparative examples, it was confirmed that the powder of the component (C) precipitated. For example, when an alkyl acrylate copolymer such as an acrylates copolymer was used instead of the component (A), it was confirmed that the component (C) precipitated (see Comparative Examples 2 and 4).

[0121] From the above, it was demonstrated that the cleaning composition of the present invention, which uses, among various thickeners, particularly the (acrylates / C10-30 alkyl acrylate) crosspolymer, can effectively suppress the settling of the powder, which is component (C).

[0122] Furthermore, as shown in Table 1, it was confirmed that the cleaning composition of the present invention containing components (A), (B), and (C) did not cause precipitation of fatty acids even after storage at 4°C for 2 months.

[0123] Furthermore, as shown in Tables 1 to 3, it was confirmed that the cleaning composition of the present invention containing components (A), (B), and (C) has excellent rinsing properties and foaming properties. On the other hand, it was confirmed that, as in the comparative examples, in cleaning compositions containing a thickener other than component (A), component (B), and component (C), the rinsing properties were particularly poor, and therefore both rinsing properties and foaming properties could not be achieved. For example, when an alkyl acrylate copolymer such as an acrylates copolymer was used instead of component (A), the rinsing properties were poor, and therefore both rinsing properties and foaming properties could not be achieved (see Comparative Examples 2 and 4).

[0124] In addition, it was confirmed that the composition of the present invention can effectively suppress powder settling even at low viscosity (see, in particular, Example 1). Therefore, it was confirmed that when the composition of the present invention is used as a cleaning composition, a formulation with low viscosity can be prepared, and therefore a cleaning composition with excellent foaming properties can be obtained.

[0125] From the above, it was confirmed that when the composition of the present invention is used as a cleaning composition, the settling of powder is effectively suppressed, the stability is excellent under low temperature conditions, and further, the cleaning properties such as rinsing ability and foaming ability are excellent.

[0126] In addition, when a cleaning composition contains a cationic polymer (D) that contributes to an odor suppression effect, etc., the composition tends to become sticky and the rinsing properties become poor. However, it has been confirmed that the cleaning composition of the present invention, which contains the cationic polymer (D) in addition to the components (A), (B), and (C), can suppress the stickiness caused by the cationic polymer (D) and can provide a cleaning composition with excellent rinsing properties.
