DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent for a plastic surface for removing fixed dirt, such as water stains and dark spots, attached to the surface of a soft plastic used in a plastic bathtub or the like, which is difficult to remove by ordinary cleaning. It is about.

[0002]

2. Description of the Related Art Conventionally, in order to remove dirt adhered to a soft material surface such as plastic without damaging the material, there is a method other than using a liquid detergent such as a liquid detergent for a bath or a liquid detergent for a kitchen. There was no. However, the detergency of these detergents was inferior to that of a cleanser containing an abrasive. On the other hand, the cleanser is intended to exert abrasive power and emulsifying and dispersing power on these stains,
Many existing cleansers meet these requirements. Abrasive cleaning agents such as cleansers contain a large amount of abrasive powder components, as can be seen from the intended use,
The cleaning power is enhanced by the polishing power, and the more the powder that is the polishing component, the higher the cleaning power.However, when the powder component is increased, the soft material surface is only damaged. Therefore, there is a problem that usability such as fluidity is deteriorated. In general, the abrasive component has a higher abrasive power as the particle size is larger. It is possible to increase the particle size in order to increase the abrasive force, but with this, a soft material surface such as plastic can be used. In such a case, the damage becomes severe and the original surface is lost, which is not preferable. Therefore, if the particle size is reduced, the scratch resistance can be improved, but the polishing and cleaning power of the cleanser is rather lowered, and as a result, the dirt removal performance is lowered. At Cleanser, to solve these problems,
The use of zeolites and various abrasives has been carried out (JP-A-55-5947, JP-A-1-170694).
issue). However, the use of these compositions has only resulted in the recent widespread inadequacy of damaging soft plastic bath products and of removing dark stains found in plastic bathtubs. It was not obtained and there was no satisfactory product.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a soft material such as a plastic material while maintaining the polishing and detergency of the dirt stuck to the surface of the material while suppressing the damage on the soft material surface such as a plastic material. It is an object of the present invention to provide a water-insoluble powder-containing composition.

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, dirt stuck to the plastic surface was removed by washing with a specific nonionic activator. It has been found that it can be made easier, while at the same time adding a specific water-insoluble powder to it to enhance its abrasive cleaning power.

That is, according to the present invention, there is provided a detergent composition for a plastic surface containing 2 to 10% by weight of a nonionic surfactant and 40 to 60% by weight of a water-insoluble powder having a Mohs hardness of 2 to 7, The nonionic surfactant is one or more surfactants selected from the group consisting of fatty acid alkanolamides and alcohol ethoxylates having 6 to 12 carbon atoms in the alkyl group, and the water-insoluble powder has an average particle diameter of 10 μm or less. In addition, the present invention provides a plastic surface cleaning composition comprising a water-insoluble powder having a particle size distribution of 50% or more of powder having a particle size of less than 10 μm.
