Description

The present invention relates to a mist-type hair cosmetic composition, and in particular to a mist-type hair cosmetic composition that is applied before using a hair iron. It can be sprayed as a mist, is easy to run your fingers through when applied, and has good hold, gives manageability and shine to hair despite not leaving a sticky or filmy finish.

Nowadays, with the spread of social media, anyone can easily watch videos on simple hair styles and how to curl their hair, making it easy to enjoy styling your own hair.

One of the tools used when styling hair is the hair iron. In recent years, the types of hair irons that have become popular include straightening irons, which straighten hair, and curling irons, which curl hair.

However, using a hair iron can denature the proteins in the hair, leading to damage. As a result, there is a growing demand for styling products that can be applied before using a hair iron and that protect the hair from heat.

In recent years, a finish that emphasizes manageability and shine has become popular, but there is a concern that if oily hair cosmetics such as hair oil or balm are applied before using a hair iron, the hair cosmetics will not evaporate and the hair iron will become dirty. For this reason, water-based hair cosmetics are preferred as hair cosmetics to apply before using a hair iron, and mist-type hair cosmetics are particularly popular as they can be applied widely and evenly with one hand.

Various formulations have been developed for mist-type hair cosmetic compositions that are applied before using a hair iron, with the aim of protecting the hair from heat (Patent Document 1), eliminating the sound of evaporation when the iron is applied and providing smoothness to the hair (Patent Document 2), and making it easier to style the hair by providing softness to the hair (Patent Document 3).

However, the composition of Patent Document 1 above can leave a crisp, filmy feeling due to the resin after using a hair iron. The compositions of Patent Documents 2 and 3 above leave a light finish, compromising manageability and shine. Furthermore, with aqueous hair cosmetics applied before using a hair iron, not only is the water evaporated by the hair iron, but the resin must also provide hold, making it difficult to achieve manageability and shine without the filmy feeling caused by the resin.

Therefore, the present invention relates to a mist-type hair cosmetic composition, and in particular, an object of the present invention is to provide a mist-type hair cosmetic composition that can be sprayed as a mist, that is easy to run your fingers through when applied, and that has good hold and gives manageability and shine to hair despite not leaving a sticky or filmy finish.

In light of these circumstances, the inventors of the present invention conducted extensive research and discovered that by incorporating (A) an amphoteric film-forming resin, (B) a nonionic surfactant with an HLB of 6.5 or higher, and (C) a modified silicone into a mist-type hair cosmetic composition to be applied before using a hair iron, the composition can be sprayed as a mist, the hair feels smooth to the touch when applied, and the finished product has good hold, manageability, and shine despite not being sticky or having a filmy feel. This led to the completion of the present invention.

This was done for five bundles. After loosening the five bundles by hand, the presence or absence of gloss was evaluated on a sensory scale of 5 points (very good), 4 points (good), 3 points (slightly good), 2 points (slightly poor), and 1 point (poor). The average score of all panelists was calculated, and the evaluation was made according to the following average score criteria.
(Average score criteria)
4.0 points or above: 5
3.5 points or more and less than 4.0 points: 4
3.0 points or more and less than 3.5 points: 3
2.0 points or more and less than 3.0 points: 2
Less than 2.0 points: 1

In Comparative Example 6, the POE (5) hydrogenated castor oil did not dissolve in the mist-type hair cosmetic composition of the present invention, making it impossible to evaluate.

From Examples 1 to 48 shown in Tables 1 to 6, it was confirmed that good results were obtained in terms of "mist-like," "smoothness of finger combing," "non-stickiness," "non-filmy feel," "hold," "good hold," and "gloss."

Various tests were conducted using the mist-type hair cosmetic compositions obtained in Examples 49 to 51, and the results were favorable in all areas: "mist-like," "smoothness of running fingers through," "non-stickiness," "non-filmy feel," "hold," "manageability," and "luster."
