Description

[Technical field]

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

[0002] One of the hair styling properties required for a hair styling composition is the ability to maintain the style of the hair for a long period of time (hair styling retention). Hair styling compositions containing wax that is solid at 25°C, as described in Patent Documents 1 and 2 below, can harden the hair bundle after styling, thereby enhancing the hair styling retention. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-131522 A [Patent Document 2] JP 2007-001887 A Summary of the Invention [Problem to be solved by the invention]

[0004] Hair styling using a hair styling composition is usually carried out through the steps of 1) spreading the hair styling composition on the palm to a certain extent, 2) applying the hair styling composition to the hair, and 3) styling the hair into a desired hairstyle while spreading the hair styling composition on the hair.

[0005] However, conventional hair styling compositions containing a wax that is solid at 25° C. may spread poorly on hair during styling, resulting in poor usability. For example, conventional hair styling compositions containing a wax that is solid at 25° C. may cause resistance during styling, as if fingers are caught, making styling difficult.

[0006] Furthermore, if the content of wax that is solid at 25° C. is reduced in order to improve the ease of application, the hair styling hold is reduced.

[0007] An object of the present invention is to provide a hair styling composition which contains a wax that is solid at 25°C and yet can spread well on the hair during styling and can also enhance the styling retention. [Means for solving the problem]

[0008] The present invention provides a hair styling composition comprising the following components (A), (B), (C), and (D), wherein the content of component (A) is 15.0% by mass or more and 50.0% by mass or less, and the total content of component (B) and component (C) is 30.0% by mass or more and 90.0% by mass or less, relative to 100% by mass of an oil agent that is liquid at 25°C.

[0009] Component (A): Solid wax at 25℃ Component (B): Ester oil having a molecular weight of 300 or less Component (C): Volatile hydrocarbon oil Component (D): A non-volatile oil that is liquid at 25°C and is different from ester oils and has a molecular weight of 300 or less.

[0010] In the hair styling composition of the present invention, the component (C) preferably contains the following component (C1): Component (C1): Volatile hydrocarbon oil with a flash point of 40°C or higher and 70°C or lower

[0011] In the hair styling composition of the present invention, the component (C) preferably contains the following component (C2). Component (C2): Volatile hydrocarbon oil with a flash point exceeding 70°C

[0012] In the hair styling composition of the present invention, the component (D) preferably contains the following component (D1): Component (D1): Hydrocarbon oil with a flash point of 200°C or higher

[0013] The hair styling composition of the present invention preferably does not contain any silicone compound or contains no more than 1.0% by mass of a silicone compound.

[0014] The hair styling composition of the present invention preferably contains the following component (E) and is an emulsified hair styling composition. Component (E): Water Effect of the Invention

[0015] The hair styling composition of the present invention, although it contains a wax that is solid at 25°C, can spread well on the hair during styling and can also enhance the styling retention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
