Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a shampoo composition, and more particularly to foaming during washing, which gives a good foam feel, does not squeeze the hair upon rinsing, and gives a smooth and soft feel to the washed hair. It relates to a shampoo composition.

2. Description of the Related Art Conventionally, shampoos satisfy the required quality by selecting various surfactants in consideration of foaming properties and detergency, or by combining them according to the purpose and use of the shampoo. Has been done. In shampoos, various anionic surfactants are usually used as a main component of a detergent. Among them, α-olefin sulfonates are widely used because of their high foaming power and hard water resistance. On the other hand, N-acyltaurine salts, which are another kind of anionic surfactants, have been widely used because they have low irritation to skin and ocular mucosa and have excellent foaming properties. In addition to the functions of these detergents, various attempts have been made in recent years to provide higher added value as a shampoo. For example, using a diallylammonium chloride-acrylamide copolymer and an organic carboxylate to improve foam quality, hair feel, combing, etc. (Japanese Patent No. 2558703), a specific amphoteric surfactant and a fatty acid alkanolamide type A surfactant may be blended to reduce irritation to the skin (JP-B-59-42038, JP-B-2-26677).
And a method of blending a higher fatty acid soap and a specific amphoteric surfactant to improve the foam continuity at the time of use and the foam elimination at the time of rinsing (Japanese Unexamined Patent Publication No. 6-88100). ing.

[0003]

However, in any of the above, it cannot be said that all the items such as foaming and foaming quality at the time of use, and the feel of the hair after rinsing and after washing are not sufficient, and the shampoo is excellent. Quality has not been achieved. Therefore, development of a shampoo composition which is more improved in these respects has been desired.

[0004]

Under these circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that a specific amount of tetradecene sulfonate, which is one kind of α-olefin sulfonate, is obtained. And a specific amount of N-
By combining the acyl taurine salt and the quaternary ammonium salt type cationic surfactant, good lather and a smooth and creamy lather feel can be obtained during washing, and the hair does not squeak during rinsing and is applied to the washed hair. It has been found that an excellent shampoo composition imparting smoothness and softness can be obtained, and the present invention has been completed based on these findings.

That is, the present invention provides the following components (A) to
(C), (A) 2 to 15% by weight of tetradecene sulfonate (B) 2 to 15% by weight of N-acyltaurine salt (C) Quaternary ammonium salt type cationic surfactant
A shampoo composition comprising 0.5 to 5% by weight.

Hereinafter, the present invention will be described in detail. The tetradecenesulfonic acid salt of the component (A) used in the present invention is a general-purpose anionic surfactant in a detergent, and is one of the important bases of shampoos. It is a component that is formed and is necessary to obtain a high cleaning effect of removing dirt on hair and skin. Examples of the counter base in the tetradecenesulfonic acid salt of the component (A) include sodium, potassium, monoethanolamine, diethanolamine, triethanolamine, ammonium, and arginine. In the present invention, sodium is particularly preferred.

In the present invention, the compounding amount of the tetradecenesulfonic acid salt of the component (A) is 2 to 15% by weight in the whole composition (hereinafter, unless otherwise specified, the weight% is simply indicated by%). And particularly preferably 5 to 10%. If it is less than 2%, it is difficult to obtain sufficient foaming and cleaning effects,
%, It is difficult to obtain sufficient quality as a shampoo, for example, a squeaky feeling of the hair occurs at the time of rinsing, and the feeling of use deteriorates.

The N-acyltaurine salt of the component (B) used in the present invention is also one of the important detergents for shampoos.
Although it is a component effective for improving the foam-enhancing property, in the present invention, by using together with the tetradecene sulfonate of the component (A), a good foaming property is exhibited at the time of washing, and the foam is rich. Foam, and the feel of the foam is synergistically improved, so that a smooth and creamy foam can be obtained.
The counter base in the N-acyl taurine salt of the component (B) is not particularly limited, and those usually used as bases such as sodium, potassium, monoethanolamine, diethanolamine, triethanolamine, ammonium, and arginine can be used. However, sodium is particularly preferred in the present invention. As the component (B), specifically, sodium N-cocoyl-N-methyltaurine, N
-Cocoyl-potassium N-methyltaurine, sodium N-lauroyl-N-methyltaurine, sodium N-myristoyl-N-methyltaurine, sodium N-palmitoyl-N-methyltaurine, N-stearoyl-
Examples thereof include sodium N-methyltaurine, and in the present invention, sodium N-cocoyl-N-methyltaurine and sodium N-lauroyl-N-methyltaurine are particularly preferable.

In the present invention, the compounding amount of the N-acyltaurine salt of the component (B) is 2 to 15%, preferably 3 to 10% of the total composition. If it is less than 2%, it is difficult to obtain sufficient foaming, a cleaning effect and a good foam feeling,
%, It is difficult to obtain sufficient quality as a shampoo, for example, the stability with time at low temperature is lowered, and it is difficult to form a uniform system and the appearance is deteriorated.

The quaternary ammonium salt type cationic surfactant of the component (C) used in the present invention is a component mainly incorporated in a hair conditioner, a rinsing agent and the like, and has an affinity for hair and adsorptivity. It works well and gives the hair smoothness and softness. In the present invention, by using in combination with the component (A) and the component (B), it is possible to eliminate the feeling of squeaking of the hair at the time of rinsing and to give a smooth feel to the hair without impairing foaming and the cleaning effect even in a detergent. Can be. The quaternary ammonium salt type cationic surfactant of the component (C) used in the present invention is not particularly limited as long as it is generally used in cosmetics, but is a mono-long chain alkyl type quaternary ammonium salt. And quaternary ammonium salts of di-long chain alkyl type, and quaternary ammonium salts of ethylene oxide (EO) addition type. Specifically, stearyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, dibehenyl dimethyl ammonium chloride, dicetyl dimethyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, dilauryl dimethyl ammonium chloride, Examples thereof include alkylpolyammonium chloride of dipolyoxyethylene (15EO) coconut oil, dimethylammonium dipolyoxyethylene (4EO) lauryl ether, stearyltrimethylammonium bromide, cetyltrimethylammonium bromide, and lauryltrimethylammonium bromide. Of which, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, salt Cetyl trimethyl ammonium, mono-long-chain alkyl type quaternary ammonium salts are preferred, such as bromide stearyltrimethylammonium, especially bromide stearyltrimethylammonium is preferred among them.

In the present invention, the compounding amount of the quaternary ammonium salt type cationic surfactant as the component (C) is 0.5 to 5%, preferably 1 to 2.5%, based on the whole composition.
If the amount is less than 0.5%, smoothness and softness are not sufficiently imparted to the hair, and even if it exceeds 5%, the effect of imparting smoothness and softness to the hair may be further improved. And the stability of the system as a product may be impaired.

In the present invention, the component (A) and the component (B)
In order to obtain a foam having good foaming, a cleaning effect and a smooth and creamy feel, the effect is remarkable when the blending weight ratio (A) / (B) is in the range of 6/1 to 1/3. Is more preferable.

The shampoo composition of the present invention may further comprise, in addition to the above essential components, an anionic compound other than the above components (A) and (B) within a quantitative and qualitative range which does not impair the effects of the present invention depending on the purpose. Surfactant: fatty acid alkylolamide,
