Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hair shampoo having low irritation, excellent foaming properties, excellent foaming properties, excellent use during washing and after washing, having an appropriate detergency and good stability over time. Composition.

[0002]

2. Description of the Related Art Various surfactants are used in detergent compositions according to their purposes. Among them, the hair shampoo composition directly touches the skin and the hair and is frequently used. Therefore, the surfactant, which is the main agent, is required to have low irritation. As such a surfactant, an acyl taurate-type anionic surfactant has been attracting attention and used. Further, the acyl taurate type anionic surfactant has a high foaming property and an appropriate detergency, and also has the performance required for the main ingredient of the hair shampoo composition.

[0003] The use of acyl taurate-type anionic surfactants having such excellent performance in combination with various surfactants as hair shampoo compositions has been studied. Acyl taurate type anionic surfactants, for example, amide amino acid type amphoteric surfactants or amido betaine type amphoteric surfactants, alkylolamide type nonionic surfactants and cationic surfactants or cations (Japanese Unexamined Patent Publication (Kokai) No. 8-295617), a composition comprising a combination of an amidoamino acid-type amphoteric surfactant and an amidobetaine-type amphoteric surfactant or an alkylbetaine-type amphoteric surfactant (Japanese Patent Application Laid-open No. Hei 8-295617). JP-A-5-31193), a composition comprising a combination of an amide ether sulfate type anionic surfactant and an amide amino acid type amphoteric surfactant (JP-A-5-31193).
No. 186792), a composition combining an amidoamino acid type amphoteric surfactant (JP-A-4-15298), a betaine-based amphoteric surfactant and HLB of 10-16.
(Japanese Unexamined Patent Publication No. 3-93711) comprising a combination of a nonionic surfactant, an alkylolamide-type nonionic surfactant and a cationic polymer compound, and an amidobetaine-type amphoteric surfactant and an alkyl Composition in combination with a roll amide type nonionic surfactant (JP-A-59-1984)
No. 100199) and the like.

However, one of the drawbacks of the hair shampoo composition using the acyl taurate type anionic surfactant is that although the foaming is good, the foam quality is coarse and the foam lacks the persistence. For the purpose of this improvement, there are many examples in which various amphoteric surfactants or alkylolamide-type nonionic surfactants are combined with acyltaurate-type anionic surfactants as described above. A hair shampoo composition in which an ionic surfactant is used in combination with these surfactants has drawbacks in that foaming properties are significantly impaired and stability over time is poor. Furthermore, in a hair shampoo composition using a conventional acyl taurate-type anionic surfactant, the scalp and hair have a strong squeaky feeling when rinsing after shampooing, so that finger passing is poor and the hairstyle after drying is poor. It also has a disadvantage in terms of usability that it is difficult to unite.

[0005]
