Description

The present invention is an aerosol type spray used in treating a hair iron used for forming or straightening the hair, wherein the evaporation occurs when the hot iron is brought into contact with the hair. The present invention relates to an aerosol type spray that can give a good iron slipperiness without sounding.

In recent years, trends in hairstyles have diversified, particularly among young people. A voluminous curly hair style with a firm wave on the end of the hair, a soft volley style with a gentle flowing wave, a smooth straight style, a bob style that creates a natural sense of unity, a hair An example is a natural loose one-curl style that has only been curled ahead. As a method of forming a hairstyle having diversified fashions in this manner, a method of forming using a hair iron such as "straight iron" or "curled iron" is generally used. However, the heat generation temperature of the iron used for hairstyle formation reaches 180-220 ° C, when such a high temperature iron is put on the hair, the moisture inside the hair and the hair styling agent evaporates instantaneously, It generates an evaporation sound. Many consumers have the opinion that the hair seems to be damaged if such an evaporation sound occurs, so the evaporation sound generated when using the iron is one of the points that consumers dislike It is

Moreover, in order to suppress and reduce the hair damage accompanying heat processing, various hair care compositions, such as a shampoo, a hair conditioning composition, a hair styling composition, may be applied. As such a hair care composition, for example, a water dispersible polyester resin, a hair cosmetic containing a plant extract (for example, see Patent Document 1), and a hair cosmetic containing a silylated peptide (for example, a patent) As in the literature 2) and the like, hair cosmetics containing naturally derived materials such as plant extracts and hydrolyzed proteins such as keratin and collagen have been proposed.

Further, as components other than those derived from natural materials, aerosol type misty hair cosmetic containing a siloxane compound, ethanol soluble protein derivative, and lower alcohol (see, for example, Patent Document 3), amine oxide group containing resin, and alkylene oxide attached Hair cosmetic containing a polymer (see, for example, Patent Document 4), hair cosmetic containing an amine oxide group-containing resin, and a component selected from basic amino acids, acidic amino acids, pyrrolidone carboxylic acids, urea and pantothenyl alcohol (See, for example, Patent Document 5) Hair cosmetics containing a cationic surfactant, a fatty acid polyhydric alcohol ester, and a poly (oxyethylene-oxypropylene) -alkylene-methylpolysiloxane copolymer (see, for example, a patent document) 6), water-soluble glass transition point of 180 ° C or more Polyhydric alcohol, various high-molecular polymers, and silicones such as high-molecular compounds, dimethicone copolyols having a flash point of 180 ° C. or higher, and hair cosmetics containing lower alcohols (see, for example, Patent Document 7) A hair cosmetic composition obtained by combining the above and a hair cosmetic composition containing a diester of ethoxydiglycol and cyclohexanedicarboxylic acid (see, for example, Patent Document 8) have also been proposed.

However, when styling is performed with a high temperature iron immediately after applying each of the above hair care compositions, the water contained in each hair cosmetic material is evaporated instantaneously, and the problem of accompanied by the sound of volatilization still remains. It did not clear up.

Therefore, it causes evaporation noise such as hairdressing misty hair cosmetics (for example, see Patent Document 9) in which an acrylic polymer compound, a polyhydric alcohol, and a monohydric alcohol are dissolved in a propellant. Hair cosmetics that do not contain water have also been proposed. However, even with such hair cosmetics, although the evaporation noise is improved, it has not been possible to prevent the generation of the evaporation noise at all, and it has not been possible to sufficiently solve the consumer's dissatisfaction. Furthermore, the hair cosmetic containing no water has another problem that the iron slip becomes worse when the compounding amount of the acrylic polymer compound is too large, and there is a problem in the simplicity of the styling.

It is an aerosol type spray used when processing a hair iron used for the purpose of forming a wave on a hair from this or making it straight, and it is an evaporation noise that sounds when a high temperature iron is brought into contact with the hair. It has been desired to develop an aerosol type spray which can give good iron slipperiness without noise.

In the specification, claims and abstract of the present invention, when “hair iron” is simply described without limitation, it is possible to use only a specific “straight hair iron” or “curling hair iron”. It includes all iron and iron appliances that are heat-treated by contact with “wave iron”, “rolling iron”, “waffle iron” or any other name hair. Moreover, not only the apparatus of the setting temperature about 180-220 degreeC used by a general household but the apparatus which can be set to the temperature of 200-240 degreeC or more which are used by a beauty parlor specialty store are included.
