RELATED APPLICATIONS

This application claims priority to the Japanese Patent Application 2004-308733 dated on October 22, 2004 and is hereby incorporated with reference for all purposes.

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION

The present invention relates to hair cosmetic composition, and particularly to hair cosmetic composition formulated amino-modified or ammonium-modified silicone.

PRIOR ART

It is known that hair coloring, bleaching agent, heat with a dryer and excessive brushing may cause hair damages leading to split ends, cut ends and dried hair. Therefore hair cosmetic compositions such as hair shampoo, hair rinse and hair styling agent are formulated silicone compounds for the purpose of protecting and repairing the hair damages mentioned above.

For example, a hair cosmetic composition formulated high-molecular-weight silicone ( Japanese published unexamined application No. 63-183,517 ) and that formulated amino-modified silicone ( Japanese published unexamined application No. 4-338,317 ) are disclosed.

However, the above mentioned hair cosmetic composition formulated high-molecular-weight silicone has not shown sufficient adsorption characteristics to hair, and the durability of the hair protection effect was not always satisfactory. Further, the above mentioned hair cosmetic composition formulated amino-modified silicone has not been able to provide the smooth finish because low-molecular-weight amino-modified silicones (having low degree of polymerization) were used. Furthermore, its stability as a compound was poor and so it had tended to have problems such as smell.

SUMMARY OF THE INVENTION

With the view to solve those problems of the prior arts mentioned above, the present invention intends to provide a hair cosmetic composition having an excellent hair protection effect and its long durability, and giving a moist feeling, softness and smoothness to the hair.

As the result of taking into consideration these circumstances and doing keen examinations in order to resolve the problems, the present inventors found that it was possible to obtain a hair cosmetic composition having a good absorption characteristic to hair as well as a good hair protection effect, with which the hair has no dryness nor stiff feeling and shows the moist and smooth finish by compounding amino-modified or ammonium-modified silicones having a particular degree of polymerization and a particular ratio of amination, and accomplished the present invention.

Thus, the present invention is a hair cosmetic composition characterized by comprising one or more ammo-modified or ammonium-modified silicones represented by the following formula (I): wherein each R1 is independently a methyl group, a phenyl group or a hydroxyl group, each R2 is independently a group shown by a formula R4Z, a is an integer of 0 to 3, each of m and n is a positive integer, a mean value of m+n is a range of from 4000 to 6000, and a mean value of n/m is a range of from 0.002 to 0.03, wherein R4 is an alkylene group having a carbon number of 3 to 6, and Z is represented by the following formula: wherein each R5 is independently a hydrogen atom or an alkyl group having a carbon number 1 to 30, R6 is an alkyl group having a carbon number of 1 to 30, A is a chlorine atom, a bromine atom or an iodine atom, and b is an integer of 2 to 6.

It is preferable that the compounding amount of the amino-modified or ammonium-modified silicone represented by the general formula (I) is from 0.01 to 10 % by mass.

In the hair cosmetic composition described above, it is preferable to further comprise 0.1 to 5.0 % by mass of one or more quaternary ammonium salts represented by the following formula (II): (Formula II)



        (NR7R8 3)+X-     (II)



wherein R7 is an alkyl group or a hydroxyalkyl group having a carbon number of 14 to 22, each R8 is independently an alkyl group or a hydroxyalkyl group having a carbon number of 1 to 3 or a benzyl group, and X is a halogen atom or an alkyl sulfate group having a carbon number of 1 to 2.

In the hair cosmetic composition described above, it is preferable to comprise low viscosity liquid oils selected from a group consisting of cyclic silicones, linear silicones and isoparaffinic hydrocarbons.

In the hair cosmetic composition of the present invention, the absorption characteristics to hair and the uniform finishing can be further improved by regulating the polymerization degree and the amination ratio of the compounded amino-modified or ammonium-modified silicone. This gives high hair protection effect and heir conditioning effect (moist feeling, silky, soft and smooth feeling). The durability of these effects can be also obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENT < Amino-modified or ammonium-modified silicone>

Amino-modified or ammonium-modified silicone used for the hair cosmetic composition of the present invention is shown by the following general formula (I): wherein each R1 is independently a methyl group, a phenyl group or a hydroxyl group, each R2 is independently a group shown by a formula R4Z, a is an integer of 0 to 3, each of m and n is a positive integer, a mean value of m+n is a range of from 4000 to 6000, and a mean value of n/m is a range of from 0.002 to 0.03, wherein R4 is an alkylene group having a carbon number of 3 to 6, and Z is represented by the following formula: wherein each R5 is independently a hydrogen atom or an alkyl group having a carbon number 1 to 30, R6 is an alkyl group having a carbon number of 1 to 30, A is a chlorine atom, a bromine atom or an iodine atom, and b is an integer of 2 to 6.

It is preferable that the mean value of m+n is within a range of from 4000 to 6000. If it is less than 4000 (the polymerization degree is low), the hair protection effect is not sufficient and hair becomes sticky. In addition, the stability of the compound itself lowers. If the mean value is more than 6000 (the polymerization degree is high), the finish becomes ununiformly and it gives a stiff feeling to the hair. Further, it may be difficult to compound to cosmetic compositions.

It is preferable that the mean value of n/m is within a range of from 0.002 to 0.03, and more preferable range is 0.005 to 0.01. If it is below 0.002 (the amination ratio is low), the cosmetic composition has a tendency toward showing a bad absorption characteristics to hair and the lowered durability of the hair protection effect. On the other hand, if it is more than 0.03 (the amination ratio is too high), it gives a sticky feeling to the hair.

The above mentioned amino-modified or ammonium-modified silicone can be used by one kind or in combination of more than two kinds. In case that more than two kinds of them are used in combination, it is also necessary that the mean values of m+n and n/m are in the above mentioned range.

Amino-modified or ammonium-modified polymeric silicones can be produced by the same production method as that of general amino-modified or ammonium-modified silicones. For example, it can be produced by performing the polycondensation reaction of &ggr;-aminopropylmethyldiethoxysilane, cyclic dimethylpolysiloxane and hexametyldisiloxane in the presence of an alkali catalyst.

In the present invention, the compounding amount of amino-modified or ammonium-modified silicone is from 0.01 to 10 by mass with respect to the total amount of the cosmetic composition, and preferable range is from 0.1 to 5 % by mass. If it is less than 0.01 % by mass, sufficient hair protection effect and conditioning effect can not be obtained. On the other hand, if it is more than 10 % by mass, the formulation stability deteriorates and the feeling is not good.

<Low viscosity liquid oil>

Since amino-modified or ammonium-modified silicone usable in the present invention has a high viscosity, it is preferable to dissolve it in low viscosity liquids oil so as to compound it in a hair cosmetic composition. Low viscosity liquid oils include chain silicones, cyclic silicones or isoparaffinic hydrocarbons and the like.

Chain silicone oils include, for example, dimethylpolysiloxane (viscosity 0.65 to 200 cSt/25°C) and the like.

Cyclic silicone oils include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, tetradecamethylcyclohexasiloxan and so on.

Further, isoparaffinic hydrocarbons may include those having a boiling point of from 60 to 260 degrees C at normal pressures. They may include, for example, Aisoper A, C, D, E, G, H, K, L and M (trademark) made by Exxon Mobil Corporation, Shellzole 71 (trademark) made by Shell Corporation, and Soltol 100, 130 and 220 (trademark) made by Phillips Corporation.

It is possible to use any one or more low viscosity liquid oils mentioned above. It is preferable that the total compound amount of the low viscosity liquid oils is a range of from 1 to 50 times (by mass) with respect to that of amino-modified or ammonium-modified silicones. It is also preferable that it is a range of from 1 to 90 % by mass with respect to the total amount of the cosmetic composition.

In addition, amino-modified or ammonium-modified silicones and low viscosity liquid oils may be blended separately to a hair cosmetic composition and dissolved in its system.

< Quaternary ammonium salt >

The hair cosmetic composition of the present invention can show improved absorption characteristics to hair and can give smooth feeling, luster and easiness-to-comb for hair, by blending one or more quaternary ammonium salts represented by the following formula (II): (Formula II)

If it is less than 0.1 % by mass, the effect of addition of the quaternary ammonium salts cannot be sufficiently obtained. On the other hand, if it is more than 5.0 % by mass, the viscosity of the hair cosmetic composition becomes too high and thus it is not preferable.

In the hair cosmetic composition of the present invention, it is possible to obtain a hair cosmetic composition having a more excellent conditioning effect by additionally blending one or more guanidine derivatives represented by the following formula (III): wherein R9 represents a linear or branched alkyl group, alkenyl group or alkylether group having a carbon number of 1 to 21, R10 and R11 represent a hydrogen atom or a linear or branched alkyl group or alkenyl group having a carbon number of 1 to 12 which may be substituted by a hydroxyl group, R12 and R13 represent a hydrogen atom or a linear or branched alkyl group or alkenyl group having a carbon number of 1 to 6 which may be substituted by a hydroxyl group, R14 represents a hydrogen atom or COOR15, R15 represents a hydrogen atom or a linear or branched alkyl group or alkenyl group having a carbon number of 1 to 6 which may be substituted by a hydroxyl group, p represents 0 or 1, and q, r, s represent an integral number of 0 to 9 and X represents an inorganic acid salt such as hydrochloride, bromate, sulfate and phosphate or an organic acid salt such as acetate, tartrate, citrate, p-toluene sulfate, higher fatty acid salt, glycolate, L or DL-pyrrolidone carboxylate, acidic amino acid salt and pyroglutamate.

(Manufacturing process)

  1. 1. Stearyltrimethylammonium chloride (2) and distearyldimethylammonium chloride (3) are dissolved in benyl alcohol (4) and cetanol (5).
  2. 2. Amino-modifeid silicones (1) are dissolved in dimethyl silicone (6).
  3. 3. The mixture of Step 2 is added to that of Step 1 and emulsified. And then, materials (7) to (11) are added to said emulsion and mixed.

As shown in Table 2, test examples 8-13 which are hair cosmetic compositions of the present invention containing amino-modified silicones with the m+n range of from 4000 to 6000 and n/m range of from 0.002 to 0.03 showed the good absorption characteristics to hair and the excellent conditioning effects. As shown by test examples 12 and 13, when a number of amino-modified silicones was formulated, even if each of them independently had the values which are out of the range described above, the effects were obtained, as long as the mean values of all silicones were within the above range.

On the other hand, test examples 14-16 using the amino-modified silicone with the value of m+n more than 6000 or the value of n/m less than 0.002 were inferior in the uniform finishing. In addition, although test example 15 contained the amino-modified silicone 7 which independently has the values of m+n and n/m within the above range, the sufficient effects were not obtained since the mean values were out of the range.

Further, test examples 17 and 18 using the amino-modified silicone with the value of m+n less than 4000 were inferior in the sense of use or showed the sticky finish.
