Description

The present invention relates to foam-like hair cosmetics, and in particular, has high elasticity of foam, has an appropriate feeling of foam retention without dripping, and can achieve both an appropriate defoaming speed as a hair cosmetic and hair. The present invention relates to a non-gas type foamy hair cosmetic that can give a high treatment feeling.

There are various types of hair care products such as mist type, emulsion type, cream type, oil type, aerosol type, etc. as hair care products on the market. As a relatively new type of form, non-gas type foam products are listed. It is done. Conventional foam-type hair care products were mainly aerosol-type foams and mousses, but non-aerosol-type foam-type products that do not use gas due to environmental concerns and changes in consumer preferences. This is because each company has come to propose. Such products are sometimes referred to as non-gas types or pump former types.

Among such non-gas-type hair care products, various products such as styling agents and bedclothes have been proposed as out bath products. For example, by containing a specific polyoxyethylene / polyoxypropylene decyl ether, a foam cosmetic (eg, see Patent Document 1) having excellent foamability and fine foam quality and excellent usability. Can be mentioned. However, although such hair cosmetics are excellent in foaming properties and creamy foam quality, they are not satisfactory from the viewpoint of foam retention and foam elasticity, and are especially applied to the entire hair when using the hair cosmetics. There is a problem such as dripping down. In addition, combining an anionic surfactant such as N-acylmethyltaurine salt or lauroylmethyltaurine salt with polyether-modified silicone at a specific ratio provides excellent foaming properties and a finely textured foam. Hair cosmetics (for example, see Patent Document 2 or 3), and hair cosmetic compositions for correcting hair with a combination of a cationic surfactant or amphoteric surfactant and a polyoxyethylene alkyl ether (for example, hair styling) , See Patent Document 4). However, regarding the former, since an anionic active agent that is said to be highly irritating is used, there is a concern about safety. In addition, both are suitable for rehabilitation, but are insufficient from the viewpoint of giving a feeling of care (treatment feeling) to the hair. In addition, by combining a specific polypropylene glycol or polyoxypropylene ether with a polyether-modified silicone or amino-modified silicone, a non-aerosol-type foamy hair cosmetic that is excellent in foam amount and foam quality and excellent in finish feeling (for example, And Patent Document 5), and a foam-like hair styling composition comprising a polyalkylene glycol, an oil component, and a surfactant (for example, see Patent Document 6). However, the latter is more suitable for aerosol foams, but as non-gas type foams, the stability and foaming power of the agents are not satisfactory, both of which are excellent in touch etc. I was not satisfied with the sex.

Therefore, foam-like hair that has high foam elasticity, has a suitable foam-holding feeling without dripping, and can achieve both a suitable defoaming speed as a hair cosmetic and can impart a high treatment feeling to the hair. The development of cosmetics was strongly desired.

Japanese Patent No. 3663387 Japanese Patent No. 4256092 JP 2003-160447 A JP 2001-226233 A Japanese Patent No. 4619579 JP 2003-95895 A

The present invention is a non-gas that has a high elasticity of foam, has an appropriate feeling of foam retention without dripping, and is compatible with an appropriate defoaming speed as a hair cosmetic and can impart a high feeling of treatment to hair. The object is to provide a foamy hair cosmetic of the type.

As a result of intensive studies to achieve the above object, the present inventor has obtained one or more selected from a specific surfactant, a specific polyhydric alcohol, and ethanol in a non-gas type hair cosmetic. It has been found that the above problem can be solved by combining in a specific amount.

That is, the hair cosmetic composition of the present invention is a non-gas type foamy hair cosmetic composition characterized by containing the following components (A) to (D).
(A) Stearyl trimethyl ammonium chloride 0.01-15 mass%
(B) Polyoxyethylene / polyoxypropylene butyl ether 0.01 to 5% by mass (C) Dipropylene glycol 0 to 10% by mass
(D) Ethanol 0-20% by mass

According to the present invention, the foam has high elasticity, has an appropriate foam holding feeling without dripping, and at the same time has an appropriate defoaming speed as a hair cosmetic and imparts a high treatment feeling to the hair. A non-gas type foamy hair cosmetic that can be provided can be provided.

Hereinafter, the hair cosmetic composition of the present invention will be described in detail.

The surfactant as the component (A) used in the foamy hair cosmetic of the present invention is stearyltrimethylammonium chloride which is a cationic surfactant. As these surfactants, commercially available products can be used. Examples of stearyltrimethylammonium chloride include NOF Corporation cation AB-600 (effective content 63%).

In the foamed hair cosmetic composition of the present invention, the amount of the component (A) stearyltrimethylammonium chloride is in the range of 0.01 to 15% by mass as an effective component with respect to the entire foamed hair cosmetic composition. Preferably it is 0.1-5 mass%. If the blending amount is less than 0.01% by mass, foaming properties and foam elasticity are insufficient, and if the blending amount exceeds 15% by weight, it may not be suitable for a foamy hair cosmetic from the viewpoint of touch. Not only can it be difficult to use pump former containers.

As the polyoxyethylene / polyoxypropylene butyl ether as the component (B) used in the foamed hair cosmetic of the present invention, a commercially available product can be used, for example, polyoxyethylene (17) polyoxypropylene (17) butyl ether. One example is Unilube 50MB-26 manufactured by NOF Corporation.

In the foamed hair cosmetic of the present invention, the blending amount of the component (B) polyoxyethylene / polyoxypropylene butyl ether is in the range of 0.01 to 5% by mass as an effective component with respect to the entire foamed hair cosmetic. is there. When the blending amount is less than 0.01% by mass, the feeling of treatment and foam elasticity are insufficient, and when the blending amount exceeds 5% by mass, an appropriate defoaming speed may not be obtained.

In the foamed hair cosmetic of the present invention, the amount of the component (C) dipropylene glycol is in the range of 0 to 10% by mass with respect to the entire foamed hair cosmetic, but preferably 0.1 to 0.1%. 5% by mass. If the blending amount exceeds 10% by mass, the foam elasticity is insufficient, and an appropriate defoaming speed may not be achieved.

In the foamed hair cosmetic of the present invention, the blending amount of ethanol as the component (D) is in the range of 0 to 20% by mass, preferably 5 to 15% by mass with respect to the entire foamed hair cosmetic. is there. If the blending amount exceeds 20% by mass, a suitable foam feeling and a suitable defoaming speed as a hair cosmetic may not be obtained.

In addition to the above-mentioned essential components, the foamed hair cosmetic of the present invention includes usually used compounding agents such as other surfactants, oils, moisturizers, thickeners, preservatives, antioxidants, chelating agents, Although arbitrary components, such as a pH adjuster, a fragrance | flavor, a pigment | dye, a ultraviolet absorber, a scattering agent, vitamins, and water, can be mix | blended, arbitrary components are not limited to these.

The dosage form of the foam hair cosmetic composition of the present invention is not particularly limited. For example, it can be made into a transparent liquid, an emulsion, a gel, etc., and a styling agent suitable as a hair treatment is optimal. is there. Moreover, the foam-like hair cosmetics of this invention can be manufactured by a conventional method.
