Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, and more specifically, it has excellent set-retaining properties and prevents excessive evaporation of moisture in hair when the hair is dried or blown with a dryer or the like during setting. The present invention also relates to a hair cosmetic which prevents damage from a brush, gives a glossy and moist feeling to the hair after use, has a dry feel, and can maintain a set style.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
Various hair cosmetics such as set lotion, hair spray, hair mist, hair foam, and hair blow are used for the purpose of making hairstyle easy and making hairstyle last longer. These hair cosmetics are produced by dissolving a film-forming resin for fixing hair in a suitable solvent such as water, a lower alcohol or a mixed solvent of water-lower alcohol. Also, due to the diversification and individualization of hairstyles in recent years, hair is damaged more due to long perm hair (waved hair) and style change from wavy hair to straight hair etc., and the hairstyle is set more firmly. To do this, hard type hair cosmetics are often used. Furthermore,
In daily care, most people use hair dryers to dry their hair and style them by blowing. The use of such a drier excessively volatilizes water in the hair and causes discoloration such as a dry feeling, split ends, broken hair, and reddish brown hair.

In order to prevent such volatilization of water in the hair, hair cosmetics containing glycerin, sugar derivative and the like as a moisturizer have been used. However, these hair cosmetics have a problem in that they have a very sticky feeling and a slimy feeling due to the viscosity of the ingredients themselves and have a bad feeling in use, and the damage preventing effect is not sufficient.

Accordingly, there has been a demand for a hair cosmetic composition which prevents excessive evaporation of moisture in the hair when the hair is dried or blown with a dryer or the like and has a good feeling in use.

On the other hand, betaine (particularly glycine betaine)
Attempts have also been made to blend the above with a hair treatment agent. For example, a hair treatment agent having a conditioning action in which betaine and an aliphatic organic acid not containing an amino group are combined has been proposed (Japanese Patent Publication No. 2-46002). ing. However, in this hair treatment agent, the aliphatic organic acid penetrates into the hair and breaks the salt bonds and hydrogen bonds inside the hair, so that the hair becomes soft and difficult to style, and the hair easily absorbs moisture. As a result, the hydrogen bonds in the hair, which are important for temporary styling, are easily broken, and the set hairstyle becomes difficult to hold for a long time.

[0006]

Under such circumstances, the inventors of the present invention have conducted diligent research, and as a result, if betaines and a film-forming resin were used in combination, the moisture content of hair during blowing using a drier etc. Prevents excessive volatilization, prevents damage from brushes, and gives hair a glossy and moisturizing feel.

Example 1 A hair cosmetic composition (hair mist) having the composition shown in Table 1 was produced by a conventional method, and the feel, the hair damage preventing effect, the set holding power and the gloss when this was used were evaluated. The results are shown in Table 1.

(Evaluation method) (1) Feeling (moisturization, dryness, smoothness): each hair cosmetic composition is sprayed onto a hair bundle having a length of 18 cm, a width of 5 cm and a weight of 20 g, and the hair is naturally dried. A comparison with a hair bundle (control) to which a cosmetic was not applied was sensory-evaluated by a panel of professional women based on the following criteria. A: Very good compared to the control. ◯: Slightly better than the control. Δ: equivalent to control X: Worse than the control.

(2) Hair damage preventive effect: A hair bundle consisting of 1,000 hairs was prepared, each hair cosmetic was applied, and the number of split ends and broken hairs generated after brushing 5000 times was counted. Ranking was performed by evaluation. A: 20 or less. ◯: 21 to 50 pieces. Δ: 51 to 100 pieces. X: 101 or more.

(3) Set holding power: Wet a hair bundle having a length of 18 cm and a weight of 1.5 g with water, wind it on a rod (2 cmφ) and let it dry naturally, then remove the rod from the curled hair bundle. Each of the hair cosmetics was applied to the curled hair and dried naturally. Then, dry curled hair in a constant temperature and humidity box (20 ° C, 98% RH) for 30 minutes.
It was hung and the curl elongation was observed to determine the holding power of the set. Judgment was made by measuring the length of curled hair and setting the length of the hair when applied to 100% as the set holding power,
The evaluation was performed according to the following criteria. A: 81% or more. ◯: 61 to 80%. Δ: 21 to 60%. X: 0 to 20%.

(4) Shine: A human head model (wig) with hair is coated with each hair cosmetic, and after natural drying, a comparison with a wig (control) to which no hair cosmetic is applied is compared with a light source and a distance. The sensory evaluation was performed by the expert panel based on the following criteria under a constant condition. A: Very glossy compared to the control. ◯: It is shiny compared to the control. Δ: equivalent to control X: Matter than the control.
