Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamy hair styling product, and more particularly to a foamy hair styling product which is excellent in wet feeling imparting property and hair styling power.

[0002]

2. Description of the Related Art In recent years, as hair styling agents, azole type foam products have become the mainstream. There are two types of foamy hair styling products, one that is used upright and the other that is used upside down. In both cases, press the spray button and take out the product in the shape of a ping pong ball once in the palm of your hand.
It was applied to the hair, and it was necessary to wash the hands after use.

In order to eliminate the need to wash the hand after use, a spray-type product which can be applied directly to the hair without taking it on the palm has been proposed (Japanese Patent Laid-Open No. Hei 3).
No. 178923). However, the spray-type products have been limited to hair styling products containing a hair styling resin as a main component only for the purpose of imparting hair styling power.

On the other hand, a product containing a large amount of polyhydric alcohol, sugar alcohol or a derivative thereof for imparting a moistening effect is known as a hair styling agent excellent in hair styling power and performance of imparting a wet feeling. However, this product is a type of product that is taken on the palm and applied to the hair, and a spray-type product having such characteristics has not been known so far. Therefore, there is a strong demand for a spray-type hair styling product which is excellent in wet feeling and performance of imparting hair styling power.

[0005]

However, when a polyvalent alcohol, sugar alcohol or a derivative thereof is added to a spray-type hairdressing composition for imparting a moistening effect, these components have a foam viscosity. Since the bubbles are stable and difficult to disappear, a phenomenon called after-draw occurs in which bubbles come out from the injection port even after the end of injection. When this after-draw occurs, the injection port is clogged, the container is contaminated, etc., and there are many problems in terms of commercial value.

The present invention has been made under these circumstances.
No clogging of the injection port or contamination of the container,
An object of the present invention is to provide a foamy hair styling product which is excellent in wet feeling imparting performance and hair styling power.

[0007]

According to the present invention, when a hairdressing composition having a specific composition is used by being housed in an aerosol container having a specific specification, the hairdressing composition is sprayed as a mist. The present invention has been completed by discovering that it is finely foamed on the surface, the after-drawing from the ejection port is significantly improved, and that it has excellent wet feeling imparting performance and hair styling ability.

That is, the foamed hair styling product of the present invention is
Polyhydric alcohol or sugar alcohol, and propylene oxide and / or polyalcohol or sugar alcohol
Alternatively, a hairdressing base containing a hairdressing base comprising a compound obtained by random polymerization or addition polymerization of butylene oxide or an esterified product thereof, a lower alcohol having 1 to 3 carbon atoms, a foaming agent, a propellant, and water. 0.3 to 2.0
It is characterized by being housed in an aerosol container having a housing hole diameter of mm and an injection port diameter of 0.3 to 0.7 mm.

The polyvalent alcohol, sugar alcohol, and specific derivatives thereof used as a hair styling base in the present invention are blended to impart a moistening effect (wet feeling) and hair styling power to the hair. It In particular, in addition to these effects, the specific derivative is blended to impart gloss to the hair.

Typical examples of polyhydric alcohols are propylene glycol, dipropylene glycol, 1,3-butylene glycol, glycerin, diglycerin, polyglycerin such as tetraglycerin, and ethylene glycol. ,
Examples thereof include triethylene glycol, hexylene glycol, polyethylene glycol and the like. Typical examples of sugar alcohols include sorbitol and mannitol.
And xylitol, lactose and the like.

As a compound or an esterified product thereof, which is used together with polyvalent alcohol or sugar alcohol, and which is obtained by random polymerization or addition polymerization of propylene oxide and / or butylene oxide with polyvalent alcohol or sugar alcohol. Can include compounds represented by the following general formula. _{R-O (R 1 O)} x (R 2 O) y (CH 2 -CH 2 -
O) _z R'in the formula, R is a residue of polyvalent alcohol or sugar alcohol R ₁ : propylene group x: 0 to 200 R ₂ : butylene group y: 0 to 200 (provided that x and y and Do not become 0 at the same time) z: 0 to 200 R ': hydrogen, or ester residue of acid

As the acid for forming the ester, inorganic acids such as phosphoric acid, dicarboxylic acids such as adipic acid, succinic acid, malic acid and tartaric acid, oxydicarboxylic acids having 4 carbon atoms,
Fatty acids such as isostearic acid can be used.

These compounds are widely used as a hair styling base material, for example, JP-A-53-124628 and JP-A-5-124628.
No. 2-051035, No. 0834414, No. 50-12
An example of its application is shown in No. 6841.

The amount of the hair styling base compounded in the hair styling composition used in the present invention varies depending on the desired hair styling power and strength of the wetting effect, but is preferably 10 to 50% by weight. If the amount of the hair styling base compounded is less than 10% by weight, it is difficult to obtain the desired hair styling power and wet feeling, while if it exceeds 50% by weight, the stickiness on the finished surface tends to increase, and the consumer's preference. I do not meet.

The compounding ratio of the polyvalent alcohol or sugar alcohol in the hair styling base to these derivatives is 1/6 to 6
/ 1 is preferable. When the compounding ratio of the derivative is lower than 6/1, the performance of imparting gloss to the hair tends to decrease.

The lower alcohol having 1 to 3 carbon atoms used in the present invention is methanol, ethanol or propanol, with ethanol being particularly preferred. The content of lower alcohol in the hairdressing composition is preferably 5 to 40% by weight, more preferably 10 to 25% by weight. If the blending amount is less than 5% by weight, the amount of after-drain tends to increase, and if it exceeds 40% by weight, the foamability is inferior and it is difficult to obtain fine and fine foam on the spray-coated surface.

The surfactant used as the foaming agent in the present invention is an anionic surfactant typified by polyoxyethylene alkyl ether sulfate, a cationic surfactant typified by stearyltrimethylammonium chloride, or a polycation. Nonionic surfactants typified by oxyethylene hydrogenated castor oil and amphoteric surfactants typified by 2-alkyl-N-carboxymethylhydroxyimidazolinium betaine. The content of the surfactant in the hairdressing composition is preferably 0.05 to 5% by weight, more preferably 0.1 to 2% by weight.

As the propellant in the present invention, a mixture of liquefied petroleum gas (LPG) and dimethyl ether (DME) is used. The mixing ratio (weight ratio) of both is preferably 5/95 to 30/70, more preferably 10/90 to.
25/75. Among the functions of the propellant, LPG is mainly involved in foaming, and DME is mainly involved in injection and defoaming. Therefore, when the mixing ratio of DME exceeds 5/95, the DME itself has a defoaming effect, so that after-drawing
However, the foamability of the sprayed product is inferior, and it is difficult to obtain fine foam with a fine texture on the sprayed surface. On the other hand, when the mixing ratio of LPG exceeds 30/70, fine-textured bubbles can be obtained, but after-drawing is not improved, which is not preferable. In addition, LPG is a mixture of n-propane, isobutane, and n-isobutane, and is usually 1.4 to 4.4 kg / cm ^2.
-The gauge pressure is 20 ° C.

As the aerosol container used in the present invention, any container may be used as long as the container body can withstand the pressure of a filling material such as aluminum or hard plastic and is not broken by normal force. .. An aluminum can whose inner surface is coated with a fluororesin or a polyamide-imide resin is usually used.

The injection valve mounted on the aerosol container has a great influence on the injection state of the hair styling composition. In addition to obtaining the desired injection state, the injection port is clogged during continuous use. Also needs to be considered. That is, the injection valve used in the present invention has a stem hole diameter of 0.3.
~ 0.5 mm, 2 places, preferably 0.4 ~ 0.5 m
m, the prepared hole diameter of the housing is 0.3 to 2.0 mm, preferably 0.4 to 0.6 mm, and the hole diameter of the vapor tap is 0.5.
mm or less, preferably 0.4 mm or less.

Further, a narrow passage is provided on the back side of the spray port of the actuator, which is involved in the foaming state on the spray coating surface and the spray coating surface, so that a rotational force is mechanically applied when the content is sprayed. An actuator having a mechanism (mechanical breakup) for generating and atomizing the spray is desirable.
The hole diameter of the injection port is preferably 0.3 to 0.6. If the diameter of the stem hole is less than 0.4 mm, clogging is likely to occur, and if it exceeds 0.5 mm × 2 locations, the amount of spray is too large to obtain good bubbles on the spray coated surface.

The diameter of the prepared hole of the housing is 0.3 m
If it is less than m, the amount of injection is small, good foaming cannot be obtained, and it cannot be used. When it is 2.0 mm or more, the amount of injection is too large to obtain fine foam. Further, when the hole diameter of the vapor tap is 0.5 mm or more, foaming and spraying on the coated surface occur.
The pattern is not normal and the scattering is large, which is not preferable. Further, when the proportion of the propellant is small, the propellant is consumed from the vapor tap, so that the content may not be ejected to the end, which is not preferable. Further, with respect to the injection port of the actuator, if it is less than 0.3 mm, clogging is likely to occur and a good spray pattern cannot be obtained. If it exceeds 0.7 mm, the pattern on the spray-applied surface becomes large, and the hairdressing composition scatters over the intended coating area, so good fine bubbles cannot be obtained on the spray-coated surface. .. The hair styling composition used in the present invention may contain the following components within a range that does not adversely affect the effects of the present invention.

For example, a hair styling base material such as an amphoteric polymer resin, a nonionic polymer resin, a cationic polymer resin, and an anionic polymer resin; an ultraviolet absorber such as oxobenzone;
Antibacterial preservatives such as isopropylmethylphenol and paraoxybenzoic acid ester; various oily components such as silicone oil, animal and vegetable oils and ester oils; amino acids, protein degradation products (derivatives), various vitamins, and various plant extracts Examples include pH adjusters such as extracts, triethanolamine, sodium hydroxide, citric acid, and phosphoric acid, as well as dyes and antioxidants.

[0024]

In the foamed hair styling composition of the present invention, polyvalent alcohol or sugar alcohol, and propylene oxide and / or butylene oxide are randomly polymerized or polymerized on these polyvalent alcohol or sugar alcohol. A hair styling composition comprising a hair styling base comprising an addition-polymerized compound or an esterified product thereof and a lower alcohol having 1 to 3 carbon atoms is used. Therefore, the hair styling power and the performance of imparting a wet feeling to the hair are excellent, and the performance of imparting gloss to the hair is also exhibited. The performance of imparting gloss to the hair cannot be obtained by blending only polyhydric alcohol or sugar alcohol.

Further, in the foamy hair styling product of the present invention, an aerosol container having a predetermined housing hole diameter and a predetermined injection port diameter is used. Therefore, an appropriate spray pattern can be obtained without causing clogging and after-drawing.

Example 1, Comparative Examples 1 to 8 Nine kinds of samples (azole products) in which the undiluted solution and propellant having the composition shown in Tables 1 and 2 below were contained in an aerosol container having the specifications shown in the table. Were manufactured and their performance was evaluated. The results are shown in the table.

[0033]

[Table 1]

[0034]

[Table 2]

As is clear from Tables 1 and 2, the sample containing neither polyoxypropylene (9) diglyceryl ether nor glycerin (Comparative Example 1) was inferior in any of hair styling power, wet feeling and luster. Therefore, the sample containing no polyoxypropylene (9) diglyceryl ether (Comparative Example 2) was inferior in gloss, and the sample containing no glycerin (Comparative Example 3) was inferior in wet feeling. Further, the sample containing no ethanol (Comparative Example 4) is not preferable because good foam quality cannot be obtained and after-drawing occurs.

In the samples (Comparative Examples 5 to 8) in which the housing hole diameter and the actuator hole diameter of the aerosol container were out of the range of the present invention, an appropriate spray pattern could not be obtained, and particularly, the hole was not obtained. Clogging occurred in the samples having small diameters (Comparative Examples 5 and 6).

On the other hand, a stock solution containing both polyoxypropylene (9) diglyceryl ether and glycerin, and containing ethanol, together with a propellant, has a housing hole diameter and an actuator hole diameter within the scope of the present invention. The sample of the present invention (Example 1) contained in the aerosol container in the above is excellent in all of the hair styling ability, wet feeling and luster, and good foam quality can be obtained without causing after-drop. It can be seen that a proper spray pattern can be obtained without causing clogging.

Example 2 An aerosol product was prepared in which an undiluted solution having the composition shown in Table 3 below and a propellant were housed in an aerosol container having the specifications shown in the table, and their performances were evaluated. As a result, as shown in the table, it can be seen that the sample exhibits excellent performance similar to the sample of Example 1.
