Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in recent years, some talc that exceeds the standard value of asbestos contamination has become a problem, and since it has an adverse effect on the human body, a talc-free powdery or granular skin cleanser that does not contain talc has been demanded. As a substitute for talc, powders such as corn starch or corn starch are generally used in powder skin cleansers (Patent Document 2). However, when these powders are used, problems in product quality such as the occurrence of "lumps" and "maggots" during water solubility and stickiness after use occur due to their physical properties. Therefore, an object of the present invention is to provide a powdery or granular composition for body washing that suppresses the generation of lumps and maggots during use (during water solubility) and maintains a moisturizing feeling (feeling of use) after washing.

[0005] The present inventor has intensively studied a powdery or granular composition for body washing that suppresses the generation of lumps during use and maintains a moisturizing feeling (feeling of use) after washing. As a result, surprisingly, it has been found that by having the following composition, in a powdery or granular composition for body washing, the generation of lumps during use can be suppressed and the moisturizing feeling after washing can be maintained. The present invention is based on such findings. Therefore, the present invention relates to the following. [1] (A) Aluminum octenyl succinate starch, 25 to 70% by mass based on the total amount of the composition, (B) An anionic surfactant, in a total amount of 1 to 42% by mass based on the total amount of the composition, and (C) A sugar alcohol, in a total amount of 1 to 20% by mass based on the total amount of the composition, A powdery or granular composition for body washing containing the same. [2] (D) The powdery or granular composition for body washing according to [1], further containing an amphoteric surfactant in an amount of 0.01 to 10% by mass based on the total amount of the composition. [3] (B) The powdery or granular composition for body washing according to [1] or [2], wherein the anionic surfactant contains two types, namely an amino acid-based anionic surfactant and a fatty acid soap-based anionic surfactant. [4] (A) The powdery or granular composition for body washing according to [1] or [2], wherein the content of aluminum octenyl succinate starch is 35 to 60% by mass based on the total amount of the composition. [Effects of the Invention]

[0006] According to the present invention, it is possible to provide a powdery or granular composition for body washing that suppresses the generation of lumps during use and maintains a moisturizing feeling after washing. [Modes for Carrying Out the Invention]

[0007] The present invention will be described in detail below. In this specification, unless otherwise specified, for numerical values a and b, the notation "a~b" is equivalent to "a or more and b or less". That is, the notation "a~b" includes the numerical values a and b at both ends. When only the numerical value b is provided with a unit in such a notation, the said unit shall also apply to the numerical value a.

[0008] 《Octenyl succinic acid starch aluminum; Component A》 Octenyl succinic acid starch aluminum is a starch derivative obtained by esterifying starch with octenyl succinic acid and adding an aluminum salt. The CAS registration number of octenyl succinic acid starch aluminum is 9087-61-0. Octenyl succinic acid starch aluminum may also be referred to as octenyl succinic acid starch Al or octenyl succinic acid corn starch aluminum. Examples of the starch constituting octenyl succinic acid starch aluminum include corn starch. In the present invention, as the octenyl succinic acid starch aluminum, those commercially available for use in cosmetics can be used. Examples of commercially available products include those with the trade name "DRY-FLO PURE" (manufactured by Akzo Nobel Chemicals) and the trade name "Octie" (manufactured by Nissui Chemical Co., Ltd.).

[0009] The content of the said Component A in the composition of the present invention is not particularly limited as long as the effects of the present invention can be obtained, but based on the total amount of the composition, it is 25 to 70% by mass, preferably 30 to 68% by mass, more preferably 35 to 60% by mass, still more preferably 40 to 57% by mass, and most preferably 43 to 53% by mass. If it exceeds the upper limit, the moisturizing feeling after washing deteriorates, and if it is below the lower limit, the generation of stickiness during use cannot be suppressed.

[0010] Conventionally, detergents or cosmetics to which aluminum octenyl succinate starch has been added have been manufactured. However, even though there are detergents or cosmetics to which aluminum octenyl succinate starch has been added, their content has been very small. In the present invention, by increasing the content of aluminum octenyl succinate starch and further combining it with other components B and C, it is possible to suppress the generation of stickiness during use and maintain the moisturizing feeling after washing. In the composition of the present invention, the ratio of the total amount of inorganic components (such as mica, talc, sericite, silica, synthetic mica, etc.) and starch components to the content of aluminum octenyl succinate starch (total amount of inorganic components (such as mica, talc, sericite, silica, synthetic mica, etc.) and starch components / content of aluminum octenyl succinate starch) is, for example, 1.0 or less, 0.80 or less, 0.60 or less, or 0.50 or less.

[0011] 《Anionic surfactant; Component B》 The anionic surfactant is not particularly limited as long as the effects of the present invention can be obtained, but an amino acid-based anionic surfactant or a fatty acid soap-based anionic surfactant is preferable. It is more preferable that both an amino acid-based anionic surfactant and a fatty acid soap-based anionic surfactant are included.

[0012] As the amino acid-based anionic surfactant (also referred to as N-acyl amino acid salt-based anionic surfactant), those commercially available for cosmetics can be used. Examples of the amino acid-based anionic surfactant include N-acyl glycine salt, N-acyl glutamate salt, or N-acyl glutamate triethanolamine salt. Specifically, potassium cocoyl glycinate, sodium lauroyl glutamate, potassium cocoyl glutamate, sodium cocoyl glutamate, triethanolamine cocoyl glutamate, triethanolamine cocoyl alanine, sodium cocoyl methyl alanine, potassium cocoyl taurine, sodium cocoyl methyl taurine, potassium lauroyl methyl alanine, sodium lauroyl sarcosine, potassium myristoyl glutamate, etc. can be used. Among them, N-acyl glycine salt or N-acyl glutamate salt is preferred, potassium cocoyl glycinate or sodium lauroyl glutamate is more preferred, and it is even more preferred to contain both potassium cocoyl glycinate and sodium lauroyl glutamate.

[0013] As the fatty acid soap-based anionic surfactant, those commercially available for cosmetics can be used. Examples of the fatty acid soap-based anionic surfactant include fatty acid alkali metal salts. Examples of the fatty acid moiety include lauric acid, myristic acid, palmitic acid, stearic acid, coconut oil fatty acid, hydrogenated beef tallow fatty acid, isostearic acid, oleic acid, castor oil fatty acid, olive oil fatty acid, palm oil fatty acid, etc. The alkali metal moiety is preferably potassium or sodium. The most preferred fatty acid soap-based anionic surfactant is potassium myristate.

[0014] The total amount of the anionic surfactant in the composition of the present invention is not particularly limited as long as the effects of the present invention can be obtained. However, based on the total amount of the composition, for example, it is 1 to 42% by mass, more preferably 2 to 40% by mass, still more preferably 3 to 38% by mass, still more preferably 5 to 35% by mass, and most preferably 10 to 32% by mass. If it exceeds the upper limit, the moisturizing feeling after washing deteriorates, and if it is below the lower limit, the foam necessary for washing does not generate.

[0015] The content of the amino acid-based anionic surfactant in the composition of the present invention is not particularly limited as long as the effects of the present invention can be obtained. However, based on the total amount of the composition, for example, it is 1 to 35% by mass, more preferably 2 to 32% by mass, still more preferably 3 to 30% by mass, still more preferably 5 to 28% by mass, and most preferably 10 to 28% by mass.

[0016] The content of the fatty acid soap-based anionic surfactant in the composition of the present invention is not particularly limited as long as the effects of the present invention can be obtained. However, based on the total amount of the composition, for example, it is 0.1 to 15% by mass, more preferably 1 to 10% by mass, still more preferably 2 to 8% by mass, and most preferably 3 to 7% by mass.

[0017] 《Sugar alcohol; Component C》 The sugar alcohol is not particularly limited, and those commercially available for cosmetics can be used. As the sugar alcohol, for example, trehalose, erythritol, pentaerythritol, inositol, arabinitol, xylitol, sorbitol, maltitol, mannitol, or dulcitol can be used, trehalose or mannitol is preferable, and it is more preferable to contain both trehalose and mannitol. In the composition of the present invention, as long as the effects of the present invention can be obtained, sugar alcohol derivatives such as sorbitol phosphate ester, xylitol phosphate ester, and polyoxyethylene maltitol can also be used.

[0018] The content of the component C in the composition of the present invention is not particularly limited as long as the effects of the present invention can be obtained. However, based on the total amount of the composition, for example, it is 1 to 20% by mass, more preferably 2 to 18% by mass, still more preferably 3 to 15% by mass, still more preferably 5 to 13% by mass, and most preferably 8 to 11% by mass. If it exceeds the upper limit, stickiness will occur on the skin after washing, and if it is below the lower limit, a tightening feeling will occur on the skin after washing.

[0019] 《Amphoteric surfactant; Component D》 The composition of the present invention preferably further contains an amphoteric surfactant. By including an amphoteric surfactant, foaming can be improved. The amphoteric surfactant is not particularly limited as long as the effects of the present invention can be obtained. For example, it can include aminoacetic acid betaine type amphoteric surfactants, sulfobetaine type amphoteric surfactants, phosphobetaine type amphoteric surfactants, imidazoline type amphoteric surfactants, or amide amino acid salt type amphoteric surfactants. As the amphoteric surfactant, aminoacetic acid betaine type amphoteric surfactants are preferred, and cocamidopropyl betaine is more preferred.

[0020] The content of the component D in the composition of the present invention is not particularly limited as long as the effects of the present invention can be obtained. However, based on the total amount of the composition, for example, it is 0.01 to 10% by mass, more preferably 0.1 to 6% by mass, still more preferably 0.3 to 5% by mass, still more preferably 0.5 to 4% by mass, and most preferably 1 to 3% by mass.

[0021] (Talc) The composition of the present invention preferably does not contain talc. Although the composition of the present invention can contain talc, its content is, based on the total amount of the composition, for example, 10% by mass or less, 8% by mass or less, 5% by mass or less, 3% by mass or less, 1% by mass or less, 0.5% by mass or less, or 0.1% by mass or less.

[0022] (Starch) The composition of the present invention preferably does not contain a starch component. Examples of the starch component include rice starch, corn starch, wheat starch, potato starch, and tapioca starch. In this specification, the "starch component" includes modified starch, but does not include aluminum octenyl succinate starch. The composition of the present invention can also contain a starch component, but its content is, for example, 25% by mass or less, 20% by mass or less, 15% by mass or less, 10% by mass or less, 8% by mass or less, 5% by mass or less, 3% by mass or less, 1% by mass or less, 0.5% by mass or less, or 0.1% by mass or less based on the total amount of the composition. If a large amount of the starch component is contained, it is likely to cause clogging.

[0023] (Moisture) The composition of the present invention preferably does not substantially contain moisture. "Does not substantially contain moisture" means that only the moisture contained in the raw materials and the moisture inevitably mixed in the manufacturing process is included, or that a drying treatment is performed in the manufacturing process of the composition to evaporate the moisture. The composition of the present invention can also contain moisture, but its content is, for example, 1% by mass or less, 0.5% by mass or less, or 0.1% by mass or less based on the total amount of the composition.

[0024] (Other components) The composition of the present invention can contain components added to ordinary cosmetics within a range that does not impair the effects of the present invention. The composition of the present invention can contain, for example, cationic surfactants, excipients, binders, thickeners, moisturizers, sequestering agents, preservatives, fragrances, colorants, astringents, anti-inflammatory agents, enzymes, and / or vitamins.

[0025] (Powdery or granular composition for body washing) The composition of the present invention is preferably in powder form. The "powdery or granular" composition of the present invention also includes those obtained by processing a powdery composition into granules, particularly granular form, using an excipient or a binder. The raw materials such as components A to D constituting the composition of the present invention can be in a solid form, for example, in a powder form.

[0026] The composition of the present invention can be used for face washing, body washing, hair (scalp) washing, finger washing, etc. after being foamed while dissolving in water or hot water.

[0027] The composition of the present invention can be filled in appropriate containers such as plastic containers, metal containers, glass containers, resin-made containers, or paper containers. The composition of the present invention may be in a small-sized form individually packaged in the amount used at one time.

Examples

[0028] Hereinafter, the present invention will be specifically described by way of examples, but these do not limit the scope of the present invention. Unless otherwise specified, % indicates mass%.

[0029] In this example, a powdery body wash composition was prepared with the component compositions shown in Tables 1 and 2. · Raw materials used (Component A) · Aluminum octenyl succinate starch (Component B) · Potassium cocoyl glycinate (amino acid-based anionic surfactant) · Sodium lauroyl glutamate (amino acid-based anionic surfactant) · Potassium myristate (fatty acid soap-based anionic surfactant) (Component C) · Trehalose · Mannitol (Component D) · Cocamidopropyl betaine

[0030] Each evaluation item was evaluated as follows. · Generation of remaining dirt Eight subjects, including both men and women, washed their faces using 0.5 g of the samples of each of the examples and comparative examples. The sensory evaluation (overall evaluation) was evaluated according to the following evaluation criteria. ◎: 7 or more out of 8 respondents answered that they were not bothered by the presence of lather or residue ○: 5 - 6 out of 8 respondents answered that they were not bothered by the presence of lather or residue △: 3 - 4 out of 8 respondents answered that they were not bothered by the presence of lather or residue ×: 2 or fewer out of 8 respondents answered that they were not bothered by the presence of lather or residue

[0031] · Moisturizing feeling after washing (feeling of use) Eight subjects, including both men and women, washed their faces using 0.5 g of the samples of each of the examples and comparative examples. The sensory evaluation (overall evaluation) was carried out according to the following evaluation criteria. The evaluation criteria are as follows ◎: 7 or more out of 8 respondents answered that they obtained a sufficiently moist feeling ○: 5 - 6 out of 8 respondents answered that they obtained a sufficiently moist feeling △: 3 - 4 out of 8 respondents answered that they obtained a sufficiently moist feeling ×: 2 or fewer out of 8 respondents answered that they obtained a sufficiently moist feeling

[0032] The results are shown in Tables 1 and 2

[0033]

Table 1

[0034]

Table 2

[0035] 《Examples 1 - 10》 Examples 1 - 10, which all contain components A - C, were judged to be at a level where they can be used as detergents in all evaluation items. In particular, Examples 1, 3, and 9 were excellent in both the occurrence of lather / residue and the moisturizing feeling after washing. Comparing Example 1 and Example 10, Example 1 was superior in the moisturizing feeling after washing, and it is considered that the addition of component D improved the moisturizing feeling after washing In Examples 5 and 6, the generation of lumps was confirmed by adding a small amount of corn starch. However, the generation of lumps was small, and it was determined that it was at a level that could be used as a detergent.

[0036] 《Comparative Examples 1 - 5》 In Comparative Examples 1 - 5, which lacked any of Components A - C, it was determined that one or more evaluation items were at a level where they could not be used as a detergent. In Comparative Example 1, which lacked Component A, a large number of lumps occurred. In Comparative Example 2, which lacked Component C, the item of the moisturizing feeling after washing deteriorated. In Comparative Example 3, where the amount of Component A was less than the lower limit, a large number of lumps occurred. In Comparative Example 4, where the amount of Component B was more than the upper limit, the item of the moisturizing feeling after washing deteriorated. In Comparative Example 5, which lacked Component B, both the generation of lumps and the moisturizing feeling after washing were excellent, but since almost no foaming occurred, it did not function as a detergent, and therefore, it was determined that it could not be used as a detergent.
