DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, and more particularly, to a hypoallergenic, foaming and foaming feel, and a moist and supple feel to skin and hair during and after washing. It relates to a detergent composition to be applied.

[0002]

2. Description of the Related Art Detergent compositions which come into direct contact with the human body, such as shampoos, body shampoos, facial cleansers, hand soaps, kitchen detergents, household detergents, etc.
In addition to excellent detergency and foaming power, the skin must be mildly irritating. In particular, it is an essential condition for shampoos, body shampoos, and facial cleansers that they show low irritation to the eyes. Furthermore, in recent years, the performance required for a detergent composition has been greatly changed with a change in consumer consciousness of the detergent composition. That is, in addition to detergency and hypoallergenicity, a detergent composition that imparts a moist and supple feel to skin and hair during and after washing has been desired.

Conventionally, anionic surfactants such as linear alkyl benzene sulfonates, alkyl sulfates, polyoxyethylene alkyl ether sulfates and α-olefin sulfonates have been used as the main components of surfactants in detergent compositions. Agent is used. However, although anionic surfactants have good detergency and foaming power, they have a problem that they cause irritation to skin and eyes. On the other hand, surfactants mild to the skin and eye mucosa, such as imidazoline-type or amino acid-type amphoteric surfactants and sulfosuccinic surfactants (JP-A-49-9)
No. 9104, JP-A-49-99105), but these foams are insufficient in foaming, and are particularly poor in foaming in the presence of oil secreted from the scalp and oil derived from hair styling agents.

For the purpose of improving the detergency and foaming property of a mild surfactant, especially a sulfosuccinic surfactant, various combinations of components have been studied. For example, a combination with a higher fatty acid salt (JP-A-63-161098,
146814, JP-A-1-163116), N-
Combination with acylamino acid-based anionic surfactant (JP-A-55-86893), Combination of N-acylamino acid-based anionic surfactant with fatty acid alkanolamine salt (JP-A-1-254620), α-olefin sulfone Combination of acid salt, imidazoline type surfactant and alkanolamide type nonionic surfactant (Japanese Patent Laid-Open No. 1-175927)
No.), combined use with a nonionic surfactant (JP-A-56-82)
No. 897, JP-A-1-287017, JP-A-3-15
No. 3798), combined use with an imidazoline surfactant (JP-A-55-88693), combined use with a betaine-type surfactant (JP-A-56-82898), combined use with a hydroxyphosphobetaine-type surfactant (JP-A-4-33999
, JP-A-4-36223), combined use with an amidoamine type amphoteric surfactant (JP-A-4-36394, JP-A-4-36223)
-117321), combined use of an amphoteric oxide and a fatty acid complex (JP-A-57-159897), combined use with a sugar-based surfactant (JP-A-2-231412, JP-A-4-372)
No. 698) and the like. However, the problem of improvement in cleaning properties and foaming properties has not yet been sufficiently solved.

Further, the use of a surfactant with a polyoxyethylene alkyl ether sulfate, which is a surfactant having excellent detergency and foaming power, has been studied (JP-A-56-38395).
JP-A-62-127396, JP-A-62-190
298). However, in both cases, although the cleaning power and the foaming power are improved, irritation to skin and eyes is not satisfactory. Further, a composition in which a sulfosuccinic acid-based surfactant is limited to an Mg salt (Japanese Patent Laid-Open No. 1-259)
No. 098) and the combined use with a water-soluble magnesium salt (Japanese Patent Application Laid-Open No. 1-230698) can improve the cleaning properties, but cannot be said to be sufficient in terms of usability. Accordingly, there has been a demand for a detergent composition which has low irritation, excellent foaming properties and excellent foam feel, and which imparts a moist and supple feel to the skin and hair during and after washing.

[0006]
