Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition that can achieve a finish that gives hair both moist weight and softness. [Background technology]

[0002] Hair cosmetic compositions include cosmetics that penetrate ingredients into the interior of hair and repair damage. These hair cosmetic compositions contain oils such as vegetable oils to give hair manageability and a cared-for feel. Different types of vegetable oils have different weights and textures that they impart to hair. For example, vegetable oils with a high iodine value are used to give hair manageability and a cared-for feel. Vegetable oils with a high iodine value can impart firmness and a moist weight to hair, and a smooth feel.

[0003] Vegetable oils are also sometimes combined with ingredients such as silicones to make hair easier to run your fingers through and give it shine.

[0004] For example, Patent Document 1 discloses a hair cosmetic composition containing (A) 3 to 99.4 mass% of a paraffin mixture containing isoparaffin having 12 to 16 carbon atoms, having a boiling point range of 185 to 215°C, and containing less than 10 mass% of 2,2,4,6,6-pentamethylheptane, (B) 0.1 to 5 mass% of a silicone or silicone derivative having an average degree of polymerization of 1000 to 5000, and (C) 0.5 to 8 mass% of a vegetable oil having an iodine value of 30 to 120, wherein the mass ratio (A) / (B+C) of the content of component (A) to the total content of components (B) and (C) is 1 or greater.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-009185 Summary of the Invention [Problem to be solved by the invention]

[0006] Vegetable oils with a high iodine value have the advantage of giving hair bounce and body, a moist weight, and a smooth feel. However, when a large amount of vegetable oil with a high iodine value is added, while it is expected to have a high damage care effect and a heavy, manageable finish, it can cause problems such as hair feeling stiff and sticky. Furthermore, when changing to a different vegetable oil to make hair softer, there is the issue that the weight (management) and damage care effects cannot be felt.

[0007] Therefore, an object of the present invention is to provide a hair cosmetic composition that can achieve a finish that gives hair both a moist weight and softness. [Means for solving the problem]
