Description

[Detailed description of the invention] The present invention relates to a method for manufacturing a cleaning composition.

More specifically, the present invention relates to a cleansing composition containing an adhesive component and having good fluidity. Among the surfactants that are the main components of cleaning compositions, linear alkylbenzene sulfonates and alkyl sulfate salts have extremely excellent cleaning performance, but calcium and magnesium, which are water hardness components, and salts that are insoluble in water Research is progressing on other types of surfactants or builders to produce .

Concerning builders, condensed phosphates are widely used to remove hardness components from water, but environmental issues have recently been raised. Regarding the use of other types of surfactants, nonionic surfactants that are less affected by water hardness components, polyoxyethylene alkyl (phenyl) ether sulfate salts, etc. are used. It is extremely sticky and has the drawback of deteriorating the powder properties of the cleaning composition and causing a cake fern phenomenon, and the nonionic surfactant is partially distilled off or decomposed during spray drying. The cleaning composition has the disadvantage that it cannot exhibit its original performance. Such hard water resistant surfactants are eagerly awaited for wide use due to their performance, but due to the above-mentioned drawbacks, their use is still insufficient and the development of new techniques is eagerly awaited. The present inventors have been conducting intensive research on this problem for many years, and have already published Japanese Patent Application Publication No. 52-41613 and Japanese Patent Publication No. 52-41613.
2-31242, JP-A No. 52-41612, and JP-B No. 52-30409, etc., the improvement techniques disclosed and proposed have been disclosed, but surprisingly recently, the hardness component of water has been disclosed. When blending resistant nonionic surfactants, polyoxyalkylene alkyl ether sulfate salts, etc. (i.e. sticky ingredients) with spray-dried powder containing other detergent compositions, special It has been discovered that by blending the above-mentioned adhesive substance into the spray-dried powder and granular material at the same time or immediately after blending, a cleaning composition with good powder physical properties can be obtained over time, and the present invention has been made. reached.

That is, the present invention provides a cleaning composition characterized in that immediately after pulverizing the powder, a spray-dried powder is mixed therein, and then, or simultaneously, an adhesive substance is mixed with the spray-dried powder. Regarding the manufacturing method. The method for producing a cleaning composition of the present invention requires pulverizing the granular material to a specific particle size range immediately before blending it into the spray-dried granular material. Although it is not yet clear how this process of pulverizing the powder improves the physical properties of the powder of the manufactured cleaning composition, it is clear that the new surface newly produced by the pulverizing process is the result of the spray-dried powder. It is thought that some kind of interaction occurs between the body and the sticky substance, but it is not clear yet. The timing of adding the adhesive substance may be at the same time as or after the blending of the pulverized powder or granules immediately before addition, but it is desirable to blend the viscous substance immediately after blending the powder or granules to be effective. Particularly preferred examples of the adhesive substance used in the present invention include nonionic surfactants, as well as higher alcohols and, in some cases, polyoxyalkylene alkyl or alkenyl ether sulfate salts. be done.
