Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to shampoo compositions and, more particularly, to good usability, foaming during cleaning,
The present invention relates to a shampoo composition having a good foam feel, a sufficient cleaning effect, and a smooth feel without squeezing hair upon rinsing.

[0002]

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 often used as a main component of the detergent, and among them, α
-Olefin sulfonates are widely used because of their high foaming power and hard water resistance, low irritation and low cost.

[0003]

However, this α
-Although olefin sulfonate has foaming power, when used alone, foam quality is coarse, such as squeezing hair when rinsing,
There was a defect in the usability. In addition, in order to ensure the usability (ease of use) and stability of the product, a stable and moderately high viscosity of the system is required, which is less dependent on temperature.
-It was difficult to obtain a moderately high and stable viscosity suitable for shampooing, for example, it was not possible to obtain a sufficient viscosity with an aqueous solution of an olefin sulfonate alone, and conversely, the fluidity was lowered at a low temperature. For this reason, the addition of gelling agents such as various water-soluble polymers has been studied,
Excellent quality as a shampoo has not yet been obtained, for example, the improvement is insufficient or the use tends to be unpleasant during use. Therefore, in these respects,
There has been a need for the development of improved shampoo compositions.

[0004]

Under such circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result,
Combination of a specific amount of a cationic polymer in a shampoo composition containing a specific amount of a tetradecene sulfonate, which is one kind of α-olefin sulfonate, a polyoxyethylene alkyl ether sulfate, and an amphoteric surfactant, respectively. In addition, by adjusting the pH of the composition to a range of 4.0 to 5.5, good foaming during the washing, a feeling of foam (smoothness, creamy feeling) and a sufficient washing effect can be obtained. Good hair feel (smoothness, no squeaky feeling) even after rinsing, and good usability due to moderately high viscosity with little temperature dependence even when no gelling agent is used And completed the present invention based on these findings.

That is, the present invention provides the following components (A) to
(D), (A) tetradecene sulfonate 1% by weight or more (B) polyoxyethylene alkyl ether sulfate 1
(C) amphoteric surfactant 1 to 10% by weight (D) cationic polymer 0.05 to 5% by weight, and the total amount of components (A) and (B) is 5 A shampoo composition characterized by having a pH in the range of 4.0 to 5.5.

In the present invention, the compounding amount of the tetradecene sulfonate of the component (A) or the polyoxyethylene alkyl ether sulfate of the component (B) is 1% or more of the total composition, and the component (A) The total amount of the components (B) and (B) is in the range of 5 to 15%, more preferably 7 to 12%. If the total amount of the components (A) and (B) is less than 5%, sufficient foaming occurs and a cleaning effect cannot be obtained. Also, if it exceeds 15%, a squeaky feeling of the hair will occur when rinsing,
There is a case where the quality as a shampoo is not suitable, for example, the feeling of use is deteriorated.

When the tetradecene sulfonate of the component (A) is used in combination with the polyoxyethylene alkyl ether sulfate of the component (B), at least 1% of either the component (A) or the component (B) is contained. By doing so, it is possible to obtain a shampoo composition having good flowability in a low temperature range, good usability, and foaming power. (A)
If the component is less than 1%, sufficient foaming power cannot be obtained, and if the component (B) is less than 1%, fluidity in a low-temperature region may be insufficient.

The amphoteric surfactant of the component (C) used in the present invention includes a tetradecene sulfonate of the component (A) and a polyoxyethylene alkyl ether sulfate of the component (B), which are anionic surfactants. Similarly, it is one of the important bases of shampoos and is an effective ingredient for improving the foaming property. In the present invention, however, the texture of the foams such as the smoothness of the foams during washing and the creamy feeling are also added. Is synergistically improved. In the present invention, the amphoteric surfactant of the component (C) is not particularly limited as long as it is an amphoteric surfactant usually used in shampoos and the like, but is preferably a betaine acetate-type amphoteric surfactant or an imidazoline-type amphoteric surfactant. preferable.

Among them, lauryl dimethylamino acetate betaine, coconut oil alkyldimethylaminoacetate betaine, coconut oil fatty acid amidopropyldimethylaminoacetic acid betaine, lauric acid amidopropyldimethylaminoacetic acid betaine, N-coconut fatty acid acyl-N-carboxymethoxyethyl- N-carboxymethylethylenediamine disodium is particularly preferred.

In the present invention, one or two or more amphoteric surfactants of the component (C) can be used in combination, if necessary. Is 2 to 7%. If it is less than 1%, sufficient foam amount and good foam feeling (smoothness, creamy feeling) cannot be obtained, and if it exceeds 10%, the system becomes hard, and a suitable viscosity as shampoo and good usability can be obtained. May not be possible.

The cationic polymer of the component (D) used in the present invention is a substance having a good affinity and adsorption to hair. In the present invention, a tetradecene sulfonate or a polyoxyethylene alkyl ether is used. It has the effect of reducing the feeling of squeaking of hair during rinsing, which is a disadvantage of sulfates, and imparting a smooth feel to hair. The cationic polymer as the component (D) is generally used in cosmetics and the like, and is not particularly limited as long as it can impart a conditioning effect to hair, and includes an amino group or an ammonium group bonded to a polymer chain, or Water-soluble compounds containing dimethyldiallylammonium halide as a constituent unit are preferred. In a specific example,

In the shampoo composition of the present invention, the pH of the composition affects the usability and the cleaning effect. That is, when the pH of the system is in the range of 4.0 to 5.5, the composition comprising the specific amounts of the components (A) to (D) exhibits moderately high viscosity and good detergency. Thereby, good usability suitable for a product system (easy to take in hand when used, easy to apply to hair without spilling or too hard from hands) and a washing effect can be obtained. If the pH of the system is less than 4.0, foaming is poor and a sufficient washing effect may not be obtained. If the pH exceeds 5.5, appropriate viscosity cannot be obtained and good usability is obtained. May not be possible.

The pH adjuster in the shampoo composition of the present invention is not particularly limited as long as it is generally used in shampoos and the like. However, inorganic acids such as hydrochloric acid and phosphoric acid, citric acid, lactic acid and malic acid are used.
