JP6876317B2 - Composition for non-foaming hair spray - Google Patents

Description

The present invention relates to non-foaming hairspray compositions.

Conventionally, hair spray compositions used for hair styling have been used for the purpose of maintaining a hairstyle for a long period of time by spraying it evenly over the entire hair after forming the hairstyle. At this time, in order not to break the hairstyle, it was common to avoid touching the hair as much as possible after applying the spray. However, in recent years, there has been a change in how to use the hairspray composition. Especially in the professional field such as a beauty salon, the hairspray composition is partially spray-applied while forming a hairstyle, and the hair is immediately applied. Many methods are used to adjust the hairstyle while touching.

Currently, hairspray compositions are either a conventional method of forming a hairstyle and then spraying it evenly over the entire hair, or a partial spraying of the hairspray composition while forming the hairstyle. There are two ways to use it: applying it and adjusting the style while touching the hair immediately after application.

However, in the conventional hair spray composition, in the former method, the hair to which the hair spray composition is applied may be partially thickened and hardened, so that the hair is heavy and made. Sometimes I couldn't maintain my hairstyle for a long time. In addition, since the hair is partially thickened and hardened, the hairstyle as a whole gives an uneven, glaring and unnatural luster, and further, the finger passage is poor and the hair is uncomfortable.

In the latter method, when the hair spray composition was spray-applied to the hair and immediately touched with the hair, it had strong stickiness, became sticky, and had poor operability. In addition, since the hairs are bundled into thick bundles and hardened, it is difficult for the fingers to pass through, which causes discomfort. When the adhesiveness was suppressed and the operability was prioritized, the setting force and the keeping force decreased.

Patent Documents 1 and 2 disclose foamy hair cosmetics for the purpose of preventing deterioration of usability while improving settability.

Japanese Unexamined Patent Publication No. 8-40843 Japanese Unexamined Patent Publication No. 8-40837

The hair cosmetics disclosed in Patent Documents 1 and 2 are foamy. However, when the hairstyle is adjusted by the above two methods, it is preferable that the hair spray composition is not foamy from the viewpoint of operability.

According to the present invention, the hair is not sticky to the touch immediately after being applied to the hair, does not give a feeling of weight to the hair, gives a natural luster, can be applied evenly, and has a hairstyle setting and keeping power, while having a finger. It is an object of the present invention to provide a composition for a non-foaming hair spray that has good passage.

The present inventors have diligently studied to solve the above problems. As a result, they have found that the above-mentioned problems can be solved by a non-foaming hair spray composition having the following constitution, and have completed the present invention.

The present invention is, for example, the following [1] to [4].
[1] The hair styling product stock solution and a propellant are contained, and the hair styling product stock solution contains 1 to 70% by mass of (A) methylal and (B) film-forming resin in an amount of 0.1 to 70% by mass in 100% by mass of the hair styling product stock solution. A non-foaming hair spray composition containing 20% by mass and having a ratio (mass ratio) of a hair styling product stock solution to a propellant of 80:20 to 20:80.
[2] The non-foaming hair spray composition according to [1], wherein the hair styling product stock solution further contains (C) ethanol.
[3] The non-foaming hair spray composition according to [1] or [2], wherein the hair styling product stock solution further contains (D) a polyhydric alcohol.
[4] The non-foaming hair spray composition according to any one of [1] to [3], wherein the hair styling product stock solution further contains (E) liquid oil.

According to the present invention, it is not sticky to the touch immediately after being applied to the hair, does not give a feeling of weight to the hair, gives a natural luster, can be applied evenly, and has a hairstyle setting power and a keeping power. , A composition for non-foaming hair spray with good finger passage can be provided.

Hereinafter, the non-foaming hair spray composition of the present invention will be described. Hereinafter, the composition for non-foaming hair spray of the present invention is also simply referred to as "composition".
[Composition for non-foaming hair spray]
The composition for non-foaming hair spray of the present invention can be spray-coated and used on hair, and the composition after spraying is non-foaming.

It was shaken about 5 times and the state immediately after shaking was observed.
4 points: It is transparently and uniformly dissolved, and no precipitation has occurred.
3 points: Very slight turbidity occurs, but it is uniform and no precipitation occurs.
2 points: Precipitation has occurred.
1 point: Precipitation has occurred considerably.

The compositions produced in Comparative Examples 7 and 8 were already cloudy after the preparation of the hair styling product stock solution due to the influence of the raw material components, and thus were evaluated according to the following criteria.
4 points: It was uniformly dissolved and no precipitation occurred.
3 points: No precipitation has occurred.
2 points: Precipitation has occurred.
1 point: Precipitation has occurred considerably.

All of the hair spray compositions produced in Examples 1 to 38 gave good evaluations in all the evaluation items (1) to (13). Therefore, the composition of the present invention is not sticky to the touch immediately after being applied to the hair, does not give a feeling of weight to the hair, gives a natural luster, can be applied evenly, and has a hairstyle setting power and a keeping power. However, it turns out that finger passage is good. Furthermore, the composition of the present invention does not cause flaking, has good hair styling properties, washes off, and moisturizes, and has good stability of the hair styling product stock solution and spray.

Since the hair spray composition produced in Comparative Example 1 contains a small amount of methylal (A) in the hair styling product stock solution, stickiness occurs when the hair spray composition is used, and the hair does not pass through the fingers. It was bad. In the hair spray composition produced in Comparative Example 2, since the amount of methylal (A) in the hair styling product stock solution was large, sufficient setting force and keeping force could not be obtained, and the spray stability was poor.

In the hair spray composition produced in Comparative Example 3, since the amount of the film-forming resin (B) in the hair styling product stock solution was small, sufficient setting force and keeping force could not be obtained. Since the hair spray composition produced in Comparative Example 4 contains a large amount of the film-forming resin (B) in the hair styling product stock solution, stickiness occurs immediately after the hair spray composition is applied to the hair, and the hair fingers become sticky. The street was bad.

In the hair spray composition produced in Comparative Example 5, since the ratio of the propellant to the hair styling product stock solution was small, stickiness, a feeling of weight, and deterioration of finger passage occurred. The hair spray composition produced in Comparative Example 6 had insufficient setting force and keeping force because the ratio of the propellant to the hair styling product stock solution was large.
The compositions produced in Comparative Examples 7 to 9 were foamy when sprayed, and had problems such as stickiness.
