Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creamy shampoo composition and, more particularly, to a skin which is excellent in the effect of washing away dirt, has no squeaky feeling upon rinsing, and has a uniform and stabilized powder. And a creamy shampoo composition which is mild to hair and hair.

[0002]

2. Description of the Related Art Conventionally, various surfactants have been incorporated into shampoo compositions according to the purpose and method of use. The required quality has been achieved by appropriately selecting them in consideration of foaming properties, detergency, irritation to the skin and hair, or by combining them. In shampoos, various anionic surfactants are often used as a main component of the detergent. Among them, N-long-chain acylamino acid salts have a low irritating effect on the skin and hair, and therefore have a high mildness. It has been proposed to use it for cleaning agents characterized by its hardness. (Japanese Unexamined Patent Publication No. 9-87661) In addition, fatty acid alkylolamide and the like have been used as surfactants in shampoo compositions as cleaning aids.

[0003]

However, when an N-long-chain acylamino acid salt is used as a cleansing component in a shampoo composition, it is mild on the skin and hair, but itself has a weak degreasing power, so that it becomes dirty. The fall was not sufficient, and dirt clogged in the scalp and pores remained, making it difficult to obtain a clean feeling after washing. Even when a fatty acid alkylolamide is used in combination as a cleaning aid, there is an effect of improving the detergency and the foaming property, but it has not been possible to sufficiently obtain a clean feeling after washing. In addition, a new shampoo composition that is inevitable to the feeling of squeaking of hair when rinsing with these detergents alone, excels in removing dirt from the scalp and pores, has no squeaky feeling when rinsing, and is mild to skin and hair. Development of things was desired.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present inventor has conducted intensive studies to overcome the above-mentioned drawbacks, and as a result, combined use of N-long-chain acylamino acid salt, fatty acid alkylolamide and a cationic polymer, and further, by combining a water-insoluble powder, the scalp, etc. It is mild on the skin and hair, but excels in removing dirt from the scalp and pores,
By being able to realize the lack of squeaky feeling during rinsing and the refreshing feeling of washing, and by making the dosage form creamy,
