Description

Description: FIELD OF THE INVENTION The present invention relates to a low-irritating detergent composition, more specifically, a foaming agent containing a sulfosuccinic surfactant, hydroxysulfobetay and a silicone derivative. The present invention relates to a detergent composition which is excellent in detergency, good in solubilizing property with respect to oily components and the like, good in emulsification stability and dispersion stability, excellent in feel to skin and hair during and after use, and low in irritation.

[Problems to be solved by conventional technology and invention]

Conventionally, anionic surfactants such as alkyl sulfates, polyoxyethylene alkyl sulfates, alkylbenzene sulfonates, and α-olefin sulfonates have been widely used as detergents. However, each of these surfactants has a drawback that, though varying in degree, it has skin irritation properties and, when used continuously, roughens the skin.

On the other hand, sulfosuccinic surfactants are known to be very mild to the skin, but have poor foaming properties and poor viscosity, so they were used as the main surfactants in detergents. Was small and was usually used as an additive. For example, Japanese Patent Publication No. 56-43276 discloses an example of the combination use of a conventional imidazoline-type amphoteric surfactant, an alkylbetaine-type amphoteric surfactant and an N-acylamino acid salt-type anionic surfactant.

JP-B-62-43479 discloses a combination of an ammonium sulfate salt of a secondary alcohol ethoxylate, a sulfosuccinic acid half-ester salt of a secondary alcohol ethoxylate, and an alkyl alkanol amide and / or an alkyl amine oxide. A cleaning composition is disclosed. Further, JP-A-56-38395, JP-A-5-38395
6-82895, JP-A-56-82897, JP-A-56-8
No. 2898, JP-A-57-159897, JP-A-59-1029
No. 96, JP-A-60-146864, JP-A-61-140514
JP-A-62-109897, JP-A-62-127396, JP-A-62-148599, JP-A-62-164797, JP-A-62-260893 and JP-A-62-260893 JP-A-63-161098 discloses a detergent composition or a shampoo composition comprising a sulfosuccinic surfactant in combination with other components.

Although these publications describe a detergent composition containing a sulfosuccinic surfactant, the foaming properties, detergency, and the like, while taking advantage of the low-irritating property of the sulfosuccinic surfactant, There is no disclosure of a detergent composition that simultaneously satisfies properties such as viscosity increase, smoothness and suppleness during and after washing, and conditioning properties.

On the other hand, for the purpose of improving the feel during washing and the conditioning property after washing, detergent compositions containing a cationic polymer are generally known, but an amount in which these effects are sufficiently exerted is added. In this case, there is a problem in that unpleasant stickiness occurs during the drying process, and the complex of the cationic polymer solidifies as the drying proceeds, causing stiffness and the like.

Further, in general, an oil component such as lanolin, ester oil, hydrocarbon, or silicone has been used in combination with a sulfosuccinic acid-based surfactant as a conditioning agent. For example, JP-A-62-84198 discloses a liquid detergent using a sulfosuccinic acid-based surfactant and a silicone derivative in combination. However, there has been a problem that the sulfosuccinic surfactant alone is inferior in solubilization, emulsion stability and dispersion stability of these oily components, and deteriorates in foaming property, detergency and storage stability.

Therefore, in order to solve such a problem, conventionally, alkyl alkanol amide, alkyl amine oxide, and the like have been used in combination.However, when these surfactants are added in an amount sufficient to exhibit the effect, after drying, There was a problem that a sense of tightness was generated.

Therefore, while taking advantage of the low-irritating property of the sulfosuccinic acid-based surfactant, it is excellent in foaming property and detergency, and has good solubilizing property for oily components, emulsion stability and dispersion stability, and at the same time feels at the time of washing. It has been desired to develop an excellent detergent composition which is excellent in smoothness and suppleness after washing, and has no feeling of tightness after drying.
