Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shampoo composition which imparts a feeling of slipperiness and moistness to hair after washing, and is not stiff or sticky.

[0002]

2. Description of the Related Art Washing hair removes dirt, sebum, etc. from the hair.
It is important for keeping clean and healthy hair. Therefore, the shampoo is required to have good detergency, foamability, and a good feeling of foam as basic performance.

However, in the recent diversification of life, individualization and increasing awareness of hair care among consumers,
With the shampoo having only the above basic performance, the consumer's desire cannot be satisfied, and there is no squeak when rinsing,
It is desired to have various characteristics such as good combability after drying and good hair smoothness. Among these, in recent years, along with the lengthening of women's hair, there has been a strong demand for shampoos that improve the smoothness of hair after drying.

In order to meet such a demand, it has been attempted to add a silicone or a derivative thereof to a shampoo to give the hair a slip (Japanese Patent Laid-Open No. 63-22).
010, JP-A-1-151510, etc.). Although high molecular weight silicones are generally excellent in the effect of giving a slip to the hair, they are rarely used in shampoo compositions because the viscosity of the shampoo becomes extremely high. In addition, when a high molecular weight silicone is blended in a shampoo, it is actually used as a mixture with a low molecular weight silicone (derivative), but there is a problem that the slipperiness after drying becomes insufficient. Furthermore, high molecular weight silicone tends to separate from other components and float, and there is a problem in stability when the composition is used. Further, compositions for hair using amino-modified silicones (JP-A-3-153620, JP-A-5-85918) have been proposed, but these have sufficient adhesion to hair, especially to damaged hair. No, the conditioning effect was insufficient.

[0005]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a shampoo composition which is excellent in hair conditioning effect, particularly in giving a slippery feeling, and particularly effective for damaged hair.

[0006]

[Means for Solving the Problems] Under the circumstances, the inventors of the present invention have conducted diligent research, and as a result, when a surfactant was used in combination with a specific amino-modified silicone and a silicone derivative other than this, hair damage was caused. On the other hand, they have found that a shampoo composition which does not have creaking upon rinsing, imparts good smoothness and moistness to hair, and is not stiff or sticky after drying can be obtained, and completed the present invention.

That is, the present invention provides the following component (a),
(B) and (c): (a) one or more selected from anionic surfactants, amphoteric surfactants and nonionic surfactants,
(B) The following general formula (1)

The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples. In addition, in the examples, "no squeaky feeling at the time of rinsing", "slippery feeling", "moisturizing feeling" and "stiffness of hair"
The evaluation of "non-stickiness" was performed by the following method.

That is, 20 g of healthy Japanese female hair
(15 cm long) is bundled, 1 g of shampoo is applied to this hair bundle, and the mixture is whipped for 1 minute, then rinsed under running water for 30 seconds,
The "no squeaky feeling during rinsing" was sensory-evaluated according to the following criteria. Then, water was wiped off with a towel and dried with a dryer. The "smoothness", "moistness", and "stiffness / non-stickiness" of dry hair were sensory evaluated according to the following criteria.

Evaluation Criteria (No squeaking during rinsing) ◯: At the time of rinsing, there is no squeaking in the hair, and the fingers can easily pass. Δ: At the time of rinsing, there is some squeaky hair, and finger passage is slightly bad. X: When rinsing, the hair has a squeaky texture and the fingers do not pass easily.

(Slipperiness) ⊚: A slippery feel is imparted to the hair, and the hair is extremely silky. ◯: A slippery feeling is imparted to the hair, and it is extremely dry. Δ: A slightly slippery feeling is imparted to the hair, and the hair is slightly silky. X: Hair has no slipperiness and does not dry.

(Moisture feeling) ○: The hair is moist and soft. Δ: Hair is slightly moist and slightly soft. X: Hair is not moisturized.

(No stiffness or stickiness): No feeling of stiffness or stickiness on hair. Δ: The hair feels slightly stiff and sticky. X: The hair feels stiff or sticky.
