Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mild detergent composition, and more particularly, to a foaming detergent composition containing a sulfosuccinic acid surfactant and hydroxysulfobetaine in a specific ratio. This invention relates to a detergent composition that has excellent properties in terms of cleansing properties, good solubility, emulsion stability, and dispersion stability for oily components, etc., has an excellent feel on the skin, hair, etc. during and after use, and is mildly irritating. .

[Prior art and problems to be solved by the invention] Conventionally, anionic surfactants such as alkyl sulfate salts, polyoxyethylene alkyl sulfate salts, alkylbenzene sulfonates, and α-olefin sulfonates have been used as cleaning agents. has been widely used. However, these surfactants all have skin irritation to varying degrees, and have the disadvantage of irritating the skin when used repeatedly.

On the other hand, sulfosuccinic acid surfactants are known to be very gentle on the skin, but because they lack foaming and thickening properties, they are used as the main surfactant in detergents. It was common to use it as an additive. For example, Japanese Patent Publication No. 56-43276 discloses an example of the combination with a conventional imidacillin type amphoteric surfactant, an alkyl betaine type amphoteric surfactant, and an N-acyl amino acid salt type anionic surfactant. -99
No. 104 discloses a shampoo composition containing a combination of a sulfosuccinic acid surfactant and a betaine surfactant.

Furthermore, Japanese Patent Publication No. 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 T-alkyl alkanolamides and/or alkylamine oxides. A cleaning composition is disclosed. Furthermore, JP-A-56-38395, JP-A-56-82895, JP-A-56-82

JP-A-62-260893 and JP-A-63-1
Japanese Patent No. 61098 discloses a detergent composition or shampoo composition in which a sulfosuccinic acid surfactant is combined with other ingredients.

These publications describe cleaning compositions containing sulfosuccinic acid surfactants, but while taking advantage of the low irritation properties of sulfosuccinic acid surfactants, they have good foaming properties, cleaning properties, No detergent composition has been disclosed that simultaneously satisfies the properties of thickening, smoothness and suppleness during and after washing, and conditioning properties.

On the other hand, detergent compositions containing cationic polymers are generally known for the purpose of improving the feel during washing and improving the conditioning properties after washing, but it is necessary to limit the amount to sufficiently exhibit these effects. When added, there is a problem in that an unpleasant stickiness occurs during the drying process, and as the cationic polymer complex solidifies as it dries, it causes stiffness and the like.

In addition, sulfosuccinic acid surfactants generally include lanolin,
Oil-based components such as ester oils, hydrocarbons, and silicones have been used together as conditioning agents, but sulfosuccinic surfactants alone have poor solubility, emulsion stability, and dispersion stability of these oil-based components. There was a problem that foaming properties, cleaning properties, and storage stability deteriorated.

Therefore, in order to solve this problem, T-alkyl alkanolamide, alkyl amine oxide, etc. have traditionally been used in combination, but these surfactants can be used in combination in amounts that allow their effects to be fully exhibited. However, there was a problem in that a feeling of stiffness occurred after drying.

Therefore, while taking advantage of the low irritation properties of sulfosuccinic acid surfactants, they have excellent foaming properties and detergency, and have good solubility, emulsion stability, and dispersion stability for oily components.
At the same time, it has been desired to develop an excellent cleaning composition that has excellent feel during cleaning, smoothness and suppleness after cleaning, and does not have a stiff feeling after drying.

[Means to solve the problem]

Under these circumstances, the present inventors conducted intensive research to solve the above problems regarding cleaning compositions using sulfosuccinic acid surfactants, and as a result, they found that a specific sulfosuccinic acid surfactant and hydroxyl When blended with sulfobetaine in a specific ratio, it does not affect the low irritation properties of sulfosuccinic acid surfactants to the skin and hair, has excellent foaming properties, and can be used with ester oils, lanolin, silicones, etc. The present invention was completed based on the discovery that a detergent composition having good solubility, emulsion stability and dispersion stability for oily components and an excellent feel can be obtained.
