Description

SHAMPOO COMPOSITION FIELD OF THE INVENTION This invention relates to a shampoo composition.

More particularly, it relates to a shampoo composition which imparts a smooth and creamy feel to a foam during shampooing without deteriorating deergency and gives no stickiness but rather a moist and soft touch to the hair during rinsing and after drying, thus exerting excellent conditioning effects.

BACKGROUND OF THE INVENTION In recent years, not only the detergency but also the conditioning effects (for example, smooth combing with fingers during rinsing, an excellent touch of the shampooed hair) are regarded as important factors in evaluating the performance of a shampoo. Therefore, water-soluble polymers including cationic polymers such as cationized cellulose and ampholytic polymers, have been widely used as conditioning agents.

Such a water-soluble polymer forms a complex, together with a surfactant, which deposits on the hair during rinsing to exert excellent conditioning effects. However the complex remaining on the hair causes some problems such as it imparts an unpleasant stickiness as the hair is dried; or it solidifies and makes the hair stiff after sufficient drying.

Thus, hair with an ideal touch cannot be obtained.

JP-A-62-132811 and JP-A-64-6237 each disclose a fatty acid lactic ester having a branched chain which shows conditioning effects (the term "JP-A" as used herein means an "unexamined published Japanese patent application"). This compound improves the texture of foam and imparts a moist and smooth feel to shampooed hair. When this compound is used alone in a shampoo as a conditioning agent, however, the effects achieved are unsatisfactory, because the hair becomes sticky during rinsing and after drying, though the dried hair has a moist feel.

Accordingly, it has been required to develop a shampoo composition which gives a foam of an improved texture, imparts no stickiness but a moist and soft touch to the hair after drying and permits smooth combing with the fingers.

SUMMARY OF THE INVENTION In light of the above circumstances, the present inventors have conducted extensive studies. As a result, they found that a shampoo composition, which gives a foam of an improved texture and imparts no stickiness but rather a moist and soft touch to the hair during rinsing and after drying, can be obtained by using a specific water-soluble polymer and an anionic surfactant and/or an ampholytic surfactant together with a specific anionic surfactant, thus completing the present invention.

Accordingly, the present invention provides a shampoo composition comprising the following Components (A), (B) and (C): (A) a water-soluble polymer selected from among cationic polymers and ampholytic polymers; (B) an anionic surfactant having a branched acyl group, a branched alkyl group or a branched alkenyl group, which is dispersible in water and have a Krafft point of 100C or below; and (C) a surfactant selected from among anionic surfactants other than those specified in (B) and ampholytic surfactants.
