CONSTITUTION:A shampoo composition is characterized by including (A) an amidoamine type amphoteric surfactant, (B) an amine oxide type surfactant and (C) a cationic polymer in which >=50wt.% of a detergent active component composed of one or two or more selected from anionic surfactants, amphoteric surfactants and nonionic surfactants is the amidoamine type amphoteric surfactant and amine oxide type surfactant.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shampoo composition, and more particularly to a shampoo composition which is mild to the skin, has no crease during washing and rinsing, is soft and smooth, and prevents dryness of the hair after drying, The present invention relates to a shampoo composition having an excellent moisturizing effect.

[0002]

Conventionally, as a surfactant for shampoo base, alkyl sulfate ester salt, polyoxyethylene alkyl sulfate ester salt, alkylbenzene sulfonate,
Anionic surfactants such as α-olefin sulfonates have been widely used. However, all of these surfactants have a certain degree of skin irritation and, when used continuously, have the drawback of roughening the skin. In contrast,
Amidoamine-type amphoteric surfactants are known to be extremely mild surfactants with low irritation to the skin and ocular mucosa, and recently, for example, JP-A-63-128100.
Amidoamine-type amphoteric surfactants having high versatility such as those disclosed in Japanese Patent Publication No. JP-A-2004-242242 have begun to be used as an active agent for a shampoo base instead of an anionic surfactant. However, in order to impart conditioning properties to a shampoo based on an amidoamine-type amphoteric surfactant, addition of a cationic polymer which has been conventionally used as a conditioning agent, gives a moist feeling during washing and rinsing,
Although softness is imparted to some extent, it may cause unpleasant stickiness in the process of drying the hair, or the complex of the cationic polymer and the surfactant may solidify as the hair dries, causing stiffness, etc. It did not reach the desired feeling.

[0003]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to make good use of the property of amidoamine type amphoteric surfactant, which has a low irritation property, and to have a good feeling in all processes from washing the hair to rinsing and even after the drying. To provide a shampoo composition.

[0004]

Under such circumstances, as a result of intensive studies by the present inventors, as a result, a system using an amidoamine-type amphoteric surfactant and an amine oxide-type surfactant as a main cleaning active ingredient is cationic. A shampoo composition containing a polymer improves the smoothness and softness of the hair during washing and rinsing, and can impart a smooth and moist feel to the hair in all processes from the drying process to the drying process. Moreover, they have found that the skin irritation is low, and completed the present invention.

That is, the present invention contains (A) an amidoamine type amphoteric surfactant, (B) an amine oxide type surfactant and (C) a cationic polymer, and contains an anionic surfactant, an amphoteric surfactant and a nonionic surfactant. 5 of cleaning active ingredients consisting of one or more selected from ionic surfactants
