Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic, and more particularly to a hair cosmetic that imparts manageability, moisturizing and smoothness to hair, spreads well and is not sticky. [Background technology]

[0002] In recent years, consumers have been experiencing various hair-related problems, such as poor manageability and dryness due to damage caused by coloring and permanent wave treatments. To solve these problems, consumers use a variety of hair cosmetics, such as creams, oils, balms, and sprays. Among these hair cosmetics, creams are particularly popular among consumers because they can provide hair with adequate manageability and a moist feel.

[0003] Conventionally, hair cosmetics have been formulated with solid oils such as wax and setting resins to provide manageability to hair. However, hair cosmetics formulated with solid oils such as wax and setting resins have the problem of being sticky and difficult to spread. On the other hand, hair cosmetics formulated with setting resins have the problem of leaving a crisp finish, making it impossible to create the smooth, natural hairstyles that have become popular with consumers in recent years.

[0004] Conventionally, hair cosmetics contain ester oils and silicone oils to impart a moist feeling to hair, but increasing the amount of ester oils and silicone oils used can cause stickiness and make the hair less spreadable.

[0005] Patent Document 1 discloses that a hair cosmetic composition containing a cationic surfactant, a higher alcohol having 14 to 22 carbon atoms, an alkyl ester of a branched fatty acid having 2 to 6 carbon atoms, and an ester of a dimer acid can improve manageability, moisturizing, and stickiness.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-98926 Summary of the Invention [Problem to be solved by the invention]

[0007] However, although Patent Document 1 examines manageability, moist feeling, and stickiness, it does not examine smoothness or stretchiness of hair. [Means for solving the problem]

[0008] As a result of extensive research, the present inventors have found that by providing a hair cosmetic composition comprising (A) an ester of dimer acid, (B) shea butter, (C) a hydrocarbon oil that is liquid at 25°C, (D) a cationic surfactant, and (E) a higher alcohol having 12 to 24 carbon atoms, in which the content of component (A) is 0.1 to 8 mass% and the content of component (B) is 0.001 to 1 mass%, it is possible to obtain a hair cosmetic composition that imparts manageability, a moist feeling, and smoothness to hair, spreads well, and is not sticky, and have completed the present invention. [Effects of the Invention]

[0009] The present invention provides a hair cosmetic which imparts manageability, moist feeling and smoothness to hair, spreads well and is not sticky. DETAILED DESCRIPTION OF THE INVENTION
