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-acylmethyltaurine 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 salt to improve foam quality, hair feel, comb-through, and the like (Japanese Patent No. 2558703)
) Or a combination of a specific amphoteric surfactant and a fatty acid alkanolamide surfactant to reduce skin irritation (Japanese Patent Publication No. 59-42038, Japanese Patent Publication No. Hei 2-26).
No. 677), 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).
No.) has been proposed.

[0003]

However, in any of the above cases, the usability at the time of use (ease of handling when used by hand), foaming, foam quality, the feel at the time of rinsing, the feel of the washed hair For all items, it cannot be said to be sufficient, and excellent quality as a shampoo has not yet been obtained. 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 acylmethyltaurine salt, the quaternary ammonium salt type cationic surfactant and a specific cationic polymer, a suitable viscosity is obtained, the usability and the storage stability are good, and the foaming is good during washing. It has been found that a smooth and creamy foam feel is obtained, the hair does not squeak during rinsing, and an excellent shampoo composition that imparts smoothness and softness to the washed hair is obtained. The present invention has been completed.

That is, the present invention provides the following components (A) to
(D), (A) 2-15% by weight of tetradecene sulfonate (B) 2-15% by weight of N-acylmethyltaurine salt (C) Quaternary ammonium salt type cationic surfactant

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.

[0008] The N-acylmethyltaurine salt of the component (B) used in the present invention is also one of the important detergents for shampoos, and is an effective component for improving the foaming property. In the present invention, when used in combination with the tetradecenesulfonic acid salt of the component (A), a good foaming property is exhibited at the time of washing, and a rich foam is obtained, and the feel of the foam is synergistically improved to provide a smooth foam. You can get creamy foam.
The counter base in the N-acylmethyltaurine salt of the component (B) is not particularly limited, and those commonly used as bases such as sodium, potassium, monoethanolamine, diethanolamine, triethanolamine, ammonium and arginine can be used. However, in the present invention, sodium is particularly preferred. As the component (B), specifically, sodium N-cocoyl-N-methyltaurine, potassium N-cocoyl-N-methyltaurine,
Examples include sodium lauroyl-N-methyltaurine, sodium N-myristoyl-N-methyltaurine, sodium N-palmitoyl-N-methyltaurine, sodium N-stearoyl-N-methyltaurine, and the like in the present invention. Cocoyl-N-methyltaurine sodium and N-lauroyl-N-methyltaurine sodium are particularly preferred.

In the present invention, the compounding amount of the N-acylmethyltaurine salt of the component (B) is from 2 to 15%, preferably from 3 to 10%, based on the whole composition. If it is less than 2%, sufficient foaming, it is difficult to obtain a cleaning effect and a good foam feeling,
On the other hand, if it exceeds 15%, 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.

The cationized guar gum (D) used in the present invention is a thickening polysaccharide-based cationic polymer obtained by adding a cationic group to guar gum, and glycidyltrimethylammonium chloride is added to guar gum. O- (2-hydroxy-3-
A suitable example is (trimethylammonio) propyl) guar gum. Usually, chloride O- (2-
Hydroxy-3- (trimethylammonio) propyl)
The degree of substitution of the cationic group in the guar gum is from 0.1 to
0.2 is used, and those in this range are also preferred in the present invention. In the present invention, the detergent system obtained from the components (A) to (C) can give good foaming, foam quality, sensation at the time of rinsing, feeling of the washed hair, and the like. The cationized guar gum of the component enhances the feel of the foam and the conditioning effect on the hair, and further increases the viscosity of the component systems (A) to (C) moderately. Better) and the storage stability of the system can be improved to obtain better quality as a shampoo. The appropriate viscosity of the system at this time is 500 at room temperature when a B-type viscometer is used.
