Description

[Technical Field]

[0001] The present invention relates to conditioning compositions. [Background technology]

[0002] In daily hair care, hair cosmetics such as rinses, conditioners, and treatments are widely used to improve the feel of hair after shampooing.

[0003] Various hair cosmetics such as rinses, conditioners, and treatments have been proposed to suit the feel of hair desired by the user. For example, conditioning compositions containing specific polyethylene glycols or amodimethicones have been proposed to impart smoothness and manageability to hair ends (Patent Document 1).

[0004] It has also been proposed that adding sugars to hair will give it firmness and shine, and improve combability (Reference 2).

[0005] In addition, it has been proposed that the incorporation of cationic cellulose or hydroxyethyl cellulose makes it easier to straighten frizzy hair and improves smoothness and moisturizing (Reference 3). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-092040 [Patent Document 2] Japanese Patent Application Publication No. 2018-203628 [Patent Document 3] Japanese Patent Application Laid-Open No. 2004-161683 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] However, while the conditioning composition of Patent Document 1 can impart smoothness and manageability to hair ends, it has the unsatisfactory effect of leaving hair sticky when rinsed off due to its strong conditioning properties.

[0008] Furthermore, the conditioning composition of Patent Document 2 was not satisfactory in terms of manageability and moisturizing of hair ends.

[0009] Furthermore, the conditioning composition of Patent Document 3 was not satisfactory in terms of the absence of squeaking or stickiness when rinsed off.

[0010] As described above, conventional conditioning compositions have inherently conflicting problems: when a product with a high conditioning effect is used, the hair becomes sticky when rinsed off, and conversely, when a product with a low conditioning effect is used, the hair becomes rough when rinsed off. Therefore, there has been a demand for a product that satisfies both the requirements of conditioning effect and the lack of stickiness when rinsed off.

[0011] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a conditioning composition that leaves hair non-sticky and non-squeaky when rinsed off, and leaves hair moist and manageable at the ends when dried. [Means for solving the problem]

[0012] As a result of intensive research to achieve the objects of the present invention, the present inventors have found that by combining a silicone compound having an amodimethicone skeleton, a monosaccharide or disaccharide, and, if desired, a hydroxyalkyl cellulose in predetermined blending amounts, it is possible to obtain a conditioning composition that leaves hair non-sticky and non-squeaky when rinsed off, and leaves hair moisturized and manageable at the ends when dried, thereby completing the present invention.

[0013] The first invention is a conditioning composition characterized by containing the following components (A) and (B): (A) Silicone compound having an amodimethicone skeleton: 0.01 to 10% by mass (B) 0.001 to 5% by mass of one or more selected from monosaccharides and disaccharides

[0014] A second invention is the conditioning composition according to the first invention, characterized in that component (B) is one or more types selected from disaccharides.

[0015] A third invention is a conditioning composition according to the first or second invention, in which component (B) is lactose or sucrose.

[0016] A fourth invention is a conditioning composition according to any one of the first to third inventions, further comprising (C) a hydroxyalkyl cellulose.

[0017] A fifth invention is a conditioning composition according to any one of the first to fifth inventions, wherein component (C) is hydroxyethyl cellulose.

[0018] A sixth invention is a conditioning composition according to any one of the first to sixth inventions, characterized in that the content of component (C) is 0.01 to 5% by mass. [Effects of the Invention]

[0019] According to the present invention, it is possible to provide a conditioning composition that leaves hair non-sticky and non-squeaky when rinsed off, and leaves hair moist and manageable at the ends when dried. DETAILED DESCRIPTION OF THE INVENTION

[0020] The present invention will be described in detail below.

[0021] <Conditioning Composition> The conditioning composition of the present invention can be used as a hair rinse, hair conditioner, hair treatment, hair pack, hair cream, leave-on treatment, etc. The conditioning composition of the present invention can be produced by a conventional method, and its formulation is not particularly limited. Specifically, it can be used in an appropriate formulation such as a cream or emulsion. It can also be in the form of an aerosol or non-aerosol, and in the case of a non-aerosol, it can take various forms such as a squeeze foamer type or a pump foamer type.

[0022] The conditioning composition of the present invention is characterized by containing component (A) a silicone compound having an amodimethicone skeleton and component (B) one or more selected from monosaccharides or disaccharides in predetermined amounts. The conditioning composition of the present invention may also contain component (C) hydroxyalkyl cellulose, if desired. Each component of the conditioning composition of the present invention will be described in detail below.

[0023] <Component (A) Silicone compound with an amodimethicone skeleton> Component (A) used in the conditioning composition of the present invention is a silicone compound having an amodimethicone skeleton. Amodimethicone is a silicone polymer modified with an amino group at the end. In the present invention, component (A) is used as a conditioning component that imparts moisturized feeling to hair and manageable ends. Component (A) of the present invention has cationic properties due to the amino group at the end of its skeleton, and therefore easily adheres to hair. Therefore, by incorporating component (A) into the conditioning composition, the effects of the other components are synergistically enhanced, making it easier for the conditioning composition of the present invention to exert its effects. Furthermore, the presence of a cationic group makes it more likely to be adsorbed to damaged areas of hair and less likely to be removed, allowing the conditioning component to remain on the hair for a long period of time.

[0024] Component (A) of the present invention is not limited to the following, but specific examples include amodimethicone, bis(hydroxy / methoxy)amodimethicone, biscetearyl amodimethicone, (alkyl (meth)acrylate / diacetone acrylamide / amodimethicone) copolymer AMP, (bisisobutyl PEG-14 / amodimethicone) copolymer, (bisisobutyl PEG-15 / amodimethicone) copolymer, (amodimethicone / morpholinomethylsilsesquioxane) copolymer, (bisbutyloxyamodimethicone / PEG-60) copolymer, etc., and one or more of these can be used in combination. Component (A) of the present invention may also be commercially available products.

[0025] The blending amount of component (A) is 0.01 to 10% by mass, preferably 0.1 to 5% by mass, of the conditioning composition of the present invention, from the viewpoint of moisturizing the hair and manageability of the ends when dried. If the blending amount is less than 0.01% by mass, the moisturizing and manageability of the hair when dried cannot be imparted, and if the blending amount is more than 10% by mass, stickiness is observed when rinsing. Furthermore, by blending component (A) of the present invention in the above range, the effects of the other components described in detail below can be synergistically improved.

[0026] <Component (B) Monosaccharides, Disaccharides> Component (B) used in the conditioning composition of the present invention can be one or a combination of two or more selected from monosaccharides and disaccharides. In the present invention, component (B) is added to reduce squeaking during rinsing and to increase the water retention capacity of hair.

[0027] Component (B) of the present invention is not limited to the following, but specific examples include glucose, fructose, mannose, galactose, xylose, sucrose, lactose, maltose, trehalose, etc., and one or more of these can be used in combination. In the present invention, monosaccharides and disaccharides are used because, among sugars, they have a smaller molecular weight than polysaccharides, so they do not impart an excessively strong film-like feel and provide a good finish to hair when dried. Furthermore, from the perspective of hair water retention, disaccharides are preferred over monosaccharides, and lactose or sucrose are particularly preferred. It is presumed that the good effects achieved when lactose or sucrose are used are due to their excellent water retention, hair softening, and damage repair properties.

[0028] The blending amount of component (B) is 0.001 to 5% by mass, and preferably 0.01 to 1% by mass, of the conditioning composition of the present invention from the viewpoint of preventing stickiness and squeakiness on hair when rinsing. If the blending amount is less than 0.001% by mass, squeakiness occurs when rinsing, and if it exceeds 5% by mass, stickiness on hair when rinsing is observed.

[0029] <Component (C) Hydroxyalkylcellulose> The conditioning composition of the present invention preferably further contains component (C) hydroxyalkyl cellulose. Component (C) enhances the protective colloid properties and water retention of the composition and forms a coating. It is a component with excellent formability. Therefore, by further containing component (C) in addition to the above components (A) and (B), the effects of the present invention can be improved. Specific examples of component (C) include hydroxyethyl cellulose and hydroxypropyl cellulose. Among these, hydroxyethyl cellulose is preferred.

[0030] The blending amount of component (C) is preferably 0.01 to 5%, more preferably 0.05 to 1%, of the conditioning composition of the present invention from the viewpoints of preventing hair from squeaking when rinsed off and maintaining manageability of hair ends when dried. If the blending amount is less than 0.01% by mass, reduced manageability of hair ends when dried may be observed, while if the blending amount exceeds 5% by mass, reduced freedom from squeaking of hair when rinsed off may be observed.

[0031] <Other ingredients> In addition to the above-mentioned components, the conditioning composition of the present invention may contain other components that are generally incorporated into ordinary conditioning compositions depending on the purpose, as long as the effects of the present invention are not impaired.

[0032] Examples of such ingredients include higher alcohols such as stearyl alcohol and behenyl alcohol; nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene sorbitan fatty acid esters and glycerin fatty acid esters; polymeric compounds such as cationized cellulose, poly(diallyldimethylammonium chloride) and highly polymerized polyethylene glycol; higher fatty acids such as stearic acid, behenic acid and lanolin fatty acid; silicones such as highly polymerized silicone and polyether-modified silicone; anti-dandruff ingredients such as zinc pyrithione and benzalkonium chloride; lower alcohols such as ethanol, methanol, propyl alcohol and isopropyl alcohol; organic acids such as lactic acid and citric acid; and other ultraviolet absorbers, preservatives, sugars, fragrances, colorants, sequestering agents, antioxidants, various chemicals, and water. [Example]

[0033] The conditioning composition of the present invention will now be described in detail with reference to examples and comparative examples, but the present invention is not limited to these examples. First, the test methods and evaluation methods used in each example will be described.

[0034] (1) Method for evaluating whether hair feels sticky after rinsing 3 g of the conditioning compositions according to the examples and comparative examples of the present invention were applied to a 10 g bundle of hair (Bealux, Asian human hair, 30 cm long), which was then rinsed with 40°C water for 10 seconds. Ten trained evaluators observed and evaluated the hair for stickiness (balanced moisture and oiliness) during rinsing according to the following evaluation criteria, and the average of the total scores of the 10 evaluators was calculated. The average value was used to evaluate the stickiness of the hair upon rinsing, based on the following scoring criteria.

[0037] (2) Evaluation method for the absence of hair creaking during rinsing 3 g of the conditioning compositions according to the examples and comparative examples of the present invention were applied to a 10 g bundle of hair (Bealux, Asian human hair, 30 cm long), which was then rinsed with 40°C water for 10 seconds. Ten trained evaluators observed and evaluated the smoothness (smoothness) of the hair during rinsing according to the following evaluation criteria, and the average of the total scores of the 10 evaluators was calculated. The smoothness of the hair during rinsing was evaluated based on the average score criteria below.

[0038] <Evaluation criteria for hair squeakiness when rinsing> 5 points: Very smooth, fingers slide smoothly without friction when stroked 4 points: Smooth, but feels a bit heavy on the fingers when stroking 3 points: Smooth, but some parts of the hair get caught when stroking 2 points: Lack of smoothness, and hair feels caught when stroked 1 point: Not smooth, fingers do not slip when stroking

[0039] <Score criteria for hair squeakiness when rinsing> ◎: Excellent...4.5 points or more ○: Excellent...3 points or more, less than 4.5 points △: Poor...2.0 points or more, less than 3 points ×: Very poor...less than 2.0 points

[0040] (3) Evaluation method for moisturizing dry hair 3 g of the conditioning compositions according to the examples and comparative examples of the present invention were applied to a 10 g hair bundle (Bealux, Asian identical human hair, 30 cm long), which was then rinsed with 40°C water for 10 seconds. The wet hair bundle was combed 20 times, towel-dried for 5 seconds, and then dried with a hair dryer until it felt completely dry. Ten trained evaluators evaluated the moist feel of the hair (a cool or wet feel perceived by touch (a cool, wet-like feeling when the hair is picked)) according to the following evaluation criteria, and the average of the scores of the 10 evaluators was calculated. The moist feel of the hair when dried was determined based on the average score criteria below.

[0041] <Evaluation criteria for moisturized hair when dry> 5 points: When the hair is picked, it feels cold and very moist. 4 points: When the hair is picked, it feels cold and very moist. 3 points: Hair feels cool when picked, but not very moist 2 points: When the hair is picked, it feels almost completely cold and almost completely moist. 1 point: No cold feeling when plucking hair, no moist feeling at all

[0042] <Score criteria for moisturizing dry hair> ◎: Excellent...4.5 points or more ○: Excellent...3 points or more, less than 4.5 points △: Poor...2.0 points or more, less than 3 points ×: Very poor...less than 2.0 points

[0043] (4) Evaluation method for manageability of hair ends when dried 3 g of the conditioning composition according to the examples and comparative examples of the present invention was applied to a 10 g bundle of hair (Bealux, Asian human hair, length 30 cm), then rinsed with water at 40°C for 10 seconds. The wet bundle of hair was combed 20 times, towel-dried for 5 seconds, and then dried with a hair dryer until it felt completely dry. The manageability of the ends of the hair was then evaluated. The evaluation was carried out by 10 trained evaluators according to the following evaluation criteria, and the average of the scores of the 10 evaluators was calculated. The average value was used to judge the manageability of hair ends when dried based on the following score criteria.

[0044] <Evaluation criteria for manageability of hair ends when dry> 5 points: The ends of the hair are neat 4 points: The ends of the hair are a little messy, but can be quickly tidied up with a hand comb. 3 points: The ends of the hair are messy, but can be quickly tidied up with a hand comb. 2 points: The ends of the hair are messy and difficult to keep in place even with a hand comb. 1 point: The ends of the hair are extremely messy and difficult to keep in place even with a hand comb.

[0045] <Score criteria for manageability of hair ends when dry> ◎: Excellent...4.5 points or more ○: Excellent...3 points or more, less than 4.5 points △: Poor...2.0 points or more, less than 3 points ×: Very poor...less than 2.0 points

[0046] Examples 1 to 27 and Comparative Examples 1 to 9 Hair conditioners having the formulations shown in Tables 1 to 4 were prepared by a conventional method, and when used, they were evaluated for the absence of stickiness and squeaking of hair when rinsed off, and the moist feeling and manageability of hair ends when dried.
