Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mild detergent composition, more particularly a foaming and This invention relates to a detergent composition that has excellent detergency, good solubilization, emulsion stability and dispersion stability for oily components, etc., excellent feel to 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, sulfoacid surfactants are known to be very gentle on the skin, but because they have poor foaming and thickening properties, they are not used as the main surfactants in detergents. There were few examples of this, and it was usually used as an additive. For example, Japanese Patent Publication No. 56-43276 discloses an example of a combination with a conventional imidacillin type amphoteric surfactant, an alkyl betaine type amphoteric surfactant, and an N-acylamino acid salt type anionic 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 an alkyl alkanolamide and/or an alkyl amine oxide. A cleaning composition is disclosed. Furthermore, JP-A-56-38395, JP-A-56-82895, JP-A-56-82

No. 1098 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 also been used together as conditioning agents. For example, JP-A-62-84198 discloses a liquid detergent that uses a sulfosuccinic acid surfactant and a silicone derivative in combination. However, there remains the problem that sulfosuccinic acid surfactants alone have poor solubilization, emulsion stability, and dispersion stability of these oily components, resulting in poor foaming properties, detergency, and storage stability.

Therefore, in order to solve this problem, alkyl alkanolamide, alkyl amine oxide, etc. have been used in combination, but when these surfactants are blended in amounts sufficient to exhibit their effects, the There was a problem that a feeling of stiffness occurred.

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.
