Description

Technical Field

[0001] The present invention relates to a hair styling agent composition suitably used for a hair styling agent for styling hair.

Background Art

[0002] As one of the hair styling performance required for a hair styling agent composition, there is a property (hair styling retention) that can hold the styled hair shape for a long time. In a hair styling agent composition containing a wax that is solid at 25°C as described in Patent Documents 1 and 2 below, the hair bundle after styling can be made hard, so the hair styling retention can be enhanced.

Summary of the Invention

Problems to be Solved by the Invention

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

[0005] However, a conventional hair styling agent composition containing a wax that is solid at 25°C may have poor spreadability of the hair styling agent composition on the hair during styling and may be inferior in usability. For example, in a conventional hair styling agent composition containing a wax that is solid at 25°C, a resistance feeling such as the finger being caught may occur during styling, making it difficult to style the hair.

[0006] Further, when the content of the wax that is solid at 25°C is reduced to improve the coating property, the hair styling retention decreases.

[0007] The object of the present invention is to provide a hair styling composition that contains a wax that is solid at 25°C, yet can spread well on the hair during styling, and can further enhance the hair styling hold. [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 in 100% by mass of a liquid oil at 25°C.

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

[0010] In the hair styling composition of the present invention, it is preferable that component (C) 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, it is preferable that component (C) 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, it is preferable that component (D) contains the following component (D1). Ingredient (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 a silicone compound, or contains one in an amount of 1.0% by mass or less.

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

Effects of the Invention

[0015] In the hair styling agent composition of the present invention, although it is a hair styling agent composition containing a wax that is solid at 25°C, it can improve the elongation on the hair during hair styling and further enhance the hair styling retention force.
