Description

[Technical Field]

[0001] The present invention relates to a hair styling composition that is suitable for use as a hair styling agent for styling hair. [Background technology]

[0002] Hair styling compositions used to style hair can exhibit a variety of styling properties, including the ability to organize hair strands (e.g., to organize hair tightly), the ability to give hair a bundled look (manageability), the ability to set hair, the ability to lift hair, the ability to hold a hairstyle in place for a long time, the ability to impart shine to hair, and the ability to improve the smoothness of hair strands to give a smooth feel.

[0003] Hair styling compositions are designed to exhibit one or more of the above-mentioned hair styling properties depending on the desired hair styling style, the target hair type, etc. Hair styling compositions also come in various forms, such as liquid, gel, and grease, and each form of hair styling composition has different usability, feel when used, and hair styling properties. Hair styling compositions with different properties have different composition designs.

[0004] Among hair styling compositions, grease-like hair styling compositions (so-called hair greases and hair pomades) have no fluidity or have lower fluidity than gel-like hair styling compositions, and are solid or paste-like. Therefore, grease-like hair styling compositions can be filled into a jar or the like and used by simply taking an appropriate amount from the container with one's fingers, making them easy to handle. Examples of such grease-like hair styling compositions include oily grease-like hair styling compositions using liquid oil and solid oil, grease-like hair styling compositions containing polyoxyethylene hydrogenated castor oil and a polyhydric alcohol, aqueous grease-like hair styling compositions containing a large amount of a polyhydric alcohol and highly thickened with a thickener (see, for example, Patent Document 1), and aqueous grease-like hair styling compositions containing water and a film-forming polymer and highly thickened with a thickener (see, for example, Patent Document 2).

[0005] [Patent Document 1] Japanese Patent Application Publication No. 9-110649 [Patent Document 2] Japanese Patent Application Laid-Open No. 2000-34212 Summary of the Invention [Problem to be solved by the invention]

[0006] Grease-like hair styling compositions generally have the property of imparting shine to hair, but it is difficult for conventional greasy hair styling compositions containing polyoxyethylene hydrogenated castor oil and a polyhydric alcohol to enhance the hair-standing ability or improve the hair's manageability while maintaining the property of imparting shine to hair.

[0007] In conventional grease-like hair styling compositions containing polyoxyethylene hydrogenated castor oil and polyhydric alcohol, it has been considered to add a film-forming polymer to enhance the hair-standing styling power. However, when a film-forming polymer is simply added, the adhesive strength between hair strands is reduced due to the film formed by the film-forming polymer, and the hair-standing styling power is actually reduced, or the ability to form hair bundles (hair bundle-forming power) is reduced.

[0008] As described above, it is difficult for conventional grease-like hair styling compositions containing polyoxyethylene hydrogenated castor oil and polyhydric alcohol to exert all three effects of imparting good shine to hair, enhancing the styling power that stands the hair, and enhancing the power to form hair bundles (hair bundle-forming power).

For example, the content of component (A) means the total content of all components (A) in the hair styling composition.

[0052] Each component used in the hair styling composition of the present invention will be described in detail below.

[0053] (Component (A)) Component (A) is a polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 10 or more. The use of component (A) can impart grease-like properties to the hair styling composition. It is believed that the grease-like properties can be imparted by component (A) because component (A) forms hexagonal liquid crystals, but the reason is not limited to this. Furthermore, the use of component (A) can impart good shine to hair and enhance the hair-standing styling power and hair bundle forming power. Component (A) is a nonionic surfactant with an HLB value of greater than 5. Only one type of component (A) may be used, or two or more types may be used in combination.

[0054] The average number of moles of ethylene oxide added in component (A) (average number of moles of ethylene oxide (EO) added in the polyoxyethylene moiety) is 10 or more, preferably 20 or more, and preferably 200 or less, more preferably 120 or less. When the average number of moles added is equal to or more than the above lower limit and equal to or less than the above upper limit, the effects of the present invention can be more effectively exhibited.

[0055] Component (A) preferably contains polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 40 to 60. In this case, the effects of the present invention can be more effectively exhibited.

[0056] In this specification, the above-mentioned "polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 40 or more and 60 or less" may be referred to as "component (A1)".

[0057] Therefore, it is preferable that component (A) contains component (A1). The hair styling composition of the present invention preferably contains component (A1). Only one type of component (A1) may be used, or two or more types may be used in combination.

[0058] The content of component (A1) in 100% by mass of component (A) is preferably 30.0% by mass or more, more preferably 50.0% by mass or more, even more preferably 70.0% by mass or more, and particularly preferably 80.0% by mass or more. When the content of component (A1) is equal to or greater than the above lower limit, the effects of the present invention can be more effectively exhibited.

[0059] The content of component (A) in the hair styling composition of the present invention is 20.0% by mass or more and 55.0% by mass or less, based on 100% by mass. If the content of component (A) is less than 20.0% by mass, it may be impossible to impart good shine to hair, or the hair-standing and hair-bun-forming power may be reduced. If the content of component (A) is less than 20.0% by mass, the hair styling composition may not be in a grease-like state. If the content of component (A) exceeds 55.0% by mass, the hair styling composition itself may become excessively hard, resulting in reduced spreadability, increased stickiness, and reduced styling power for standing hair under weight.

[0060] The content of component (A) in 100% by mass of the hair styling composition of the present invention is preferably 22.0% by mass or more, more preferably 25.0% by mass or more, and preferably 50.0% by mass or less, more preferably 45.0% by mass or less. When the content of component (A) is equal to or greater than the above-mentioned lower limit and equal to or less than the above-mentioned upper limit, the effects of the present invention can be more effectively exhibited, and the hair styling composition is more likely to have a grease-like property. When the content of component (A) is equal to or less than the above-mentioned upper limit, the spreadability of the hair styling composition can be more improved, and stickiness can be further reduced.

[0061] (Component (B) and Component (BX)) Component (B) is an oily agent that is pasty at 25°C and / or a nonionic surfactant that is pasty at 25°C and has an HLB value of 5 or less.

When the content of component (C) is equal to or less than the above-mentioned upper limit, stickiness can be further suppressed.

[0075] (Component (D)) Component (D) is water. The hair styling composition of the present invention preferably contains component (D). By using component (D), shapability can be improved. Component (D) is preferably purified water.

[0076] The content of component (D) in 100% by mass of the hair styling composition of the present invention is preferably 20.0% by mass or more, more preferably 25.0% by mass or more, and preferably 70.0% by mass or less, more preferably 60.0% by mass or less. When the content of component (D) is equal to or greater than the above lower limit, the spreadability of the hair styling composition can be improved. When the content of component (D) is equal to or less than the above upper limit, the effects of the present invention are more effectively exhibited.

[0077] (Component (E)) Component (E) is a polyoxyethylene alkyl ether having an HLB value of 10 or more. The hair styling composition of the present invention preferably contains component (E). By using component (E), it is possible to improve shapability and further enhance the hair-standing styling power. Component (E) may be used alone or in combination of two or more types.

When the content of component (F) is above the above-mentioned lower limit, the hair-standing styling power and the retention of the stood-up hair can be further improved. When the content of component (F) is below the above-mentioned upper limit, the decrease in adhesive strength between hair strands due to component (F) can be suppressed, and therefore the hair-standing styling power and hair bundle forming power can be maintained at a high level. Furthermore, when the content of component (F) is below the above-mentioned upper limit, the hair can be imparted with even better luster.

[0092] (Component (G)) Component (G) is an oily agent that is liquid at 25°C. The hair styling composition of the present invention preferably contains component (G).
