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 specifically, it is hypoallergenic, has excellent foaming properties and feel of foam, and has a moist and supple feel to the skin and hair during and after washing. The present invention relates to a cleaning composition to be applied.

[0002]

[Prior Art and Problems] Cleaning compositions that directly contact the human body, such as shampoos, body shampoos, facial cleansers, hand soaps, kitchen detergents and household detergents,
In addition to excellent detergency and foaming power, mild irritation to the skin is required. In particular, shampoos, body shampoos, and facial cleansers must have low eye irritation. Furthermore, in recent years, the performance required of a detergent composition has changed significantly with the change of consumer consciousness for the detergent composition. That is, in addition to detergency and low irritation, a detergent composition which gives a moist and supple feel to the skin and hair during and after washing has been desired.

Conventionally, as a main component of a surfactant of a detergent composition, an anionic surface active agent such as linear alkylbenzene sulfonate, alkyl sulfate ester salt, polyoxyethylene alkyl ether sulfate ester salt, α-olefin sulfonate, etc. Agent is used. However, although the anionic surfactant has good detergency and foaming power, it has a problem that it is irritating to the skin and eyes. On the other hand, as a surfactant mild to the skin and ocular mucosa, for example, an imidazoline type or amino acid type amphoteric surfactant or a sulfosuccinic acid type surfactant (JP-A-49-9)
9104, JP-A-49-99105), but these do not have sufficient foaming, and in particular, foaming is inferior in the presence of oil secreted from the scalp or oil derived from a hair styling agent.

Various components have been investigated for the purpose of improving the detergency and foamability of mild surfactants, especially sulfosuccinic acid surfactants. For example, a combination with a higher fatty acid salt (JP-A-63-161098, JP-A-1)
-146814, JP-A-1-163116), N-
Combined use with an acylamino acid-based anionic surfactant (JP-A-55-86893), combined use of N-acyl-amino acid-based anionic surfactant and fatty acid alkanolamine salt (JP-A-1-254620), α-olefin sulfone Combined use of acid salt, imidazoline type surfactant and alkanolamide type nonionic surfactant (JP-A-1-175927)
No.), in combination with a nonionic surfactant (JP-A-56-82).

3798), combination with imidazoline type surfactant (JP-A-55-86893), combination with betaine-type surfactant (JP-A-56-82898), combination with hydroxyphosphobetaine-type surfactant. (JP-A-4-33999
JP-A-4-36223), combined use with amidoamine type amphoteric surfactant (JP-A-4-36394, JP-A-4-36394).
No. 117321), combined use of amphoteric oxide and fatty acid complex (JP-A-57-159897), combined use with sugar-based surfactant (JP-A-2-231414, JP-A-4-3722).
698) and the like are disclosed. However, the problems of improving the cleaning property and the foaming property have not been sufficiently solved.

Further, a combination use with a polyoxyethylene alkyl ether sulfate ester salt, which is a surfactant excellent in detergency and foaming power, was also examined (JP-A-56-38395).
JP-A-62-127396, JP-A-62-190
298). However, in all cases, the detergency and foaming power are improved, but the irritation to the skin and eyes is not satisfactory. Further, a composition in which the sulfosuccinic acid-based surfactant is limited to Mg salt (JP-A-1-259).
No. 098) and a combination with a water-soluble magnesium salt (Japanese Patent Laid-Open No. 1-230698) improve the detergency, but are not sufficient in terms of usability. Therefore, there has been a demand for a detergent composition which is low in irritation, excellent in foaming property and feel of foam, and which imparts a moist and supple feel to the skin / hair during and after washing.

[0006]
