Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cleaning composition in which a cleaning composition is packaged with a water-soluble material.

[0002]

2. Description of the Related Art A one-pack detergent (eg, JP-A-63-12467) in which a detergent for one-time washing is packaged and packaged with a water-soluble film or the like in consideration of consumer convenience, and a detergent composition is included. There is known a sheet-like laundry article comprising a layer and a water-soluble substrate on both sides of the layer (JP-A-10-72599).

On the other hand, recent washing machines tend to reduce stirring power and shorten operating time in order to cope with environmental and energy problems and economy, and to prevent damage to clothes. What exhibits sufficient washing performance by stirring is demanded.

[0004] It has been known to add an enzyme which is a chlorine repellent and an enzyme stabilizer to a detergent in order to enhance the detergency. For example, JP-A-62-57492 discloses an enzyme and a chlorine stabilizer. A composition containing a sulfite as a scavenger is hermetically packaged with a specific polymer. However, since the sulfite was disposed in the composition, the inactivation of the enzyme could not be effectively prevented, and the detergency was reduced.

The most effective way to use a detergent containing a chlorine repellent such as an enzyme is to completely remove chlorine from water used for washing. However, from the viewpoint of the convenience of the consumer, it is not possible to take much time, and it is general to mix an enzyme or the like with a chlorine scavenger to prepare a cleaning agent. In this case, although it is more effective than not using the chlorine scavenger, there is a problem of the time for the chlorine scavenger to capture chlorine and the time for the enzyme to be deactivated by chlorine, and a sufficient effect has not been obtained. For this reason, there has been a demand for a cleaning agent in which the chlorine scavenger works first and then the chlorine repellent works, even though the treatment is performed once.

[0006]

Since the film thus obtained contains water or a solvent, it is dried by a method such as a drum drying method, a belt drying method, or a hot air drying method.

A binder can be used to fix the chlorine scavenger on the surface of the water-soluble film. Examples of the binder include a water-soluble polymer, an alcohol-soluble polymer, and a petroleum-soluble polymer.
