Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a granular detergent composition containing a nonionic surfactant as a main component, which causes less exudation of the nonionic surfactant from the product during long-term storage, and a method for producing the same.

[0002]

2. Description of the Related Art Nonionic surfactants generally have a low foaming property, their detergency is hardly affected by the hardness of water, and they are particularly excellent in dirt dispersibility and stain dispersibility at low temperatures. Furthermore, it is an excellent surfactant with good biodegradability, low environmental load, low toxicity and no safety problem. Examples of the method for producing a granular detergent containing a nonionic surfactant as a main component include, for example, JP-A-52-101121 and JP-A-62-2632.
Various methods have been proposed in Japanese Patent Laid-Open No. 99, Japanese Patent Laid-Open No. 57-159898, and the like.

However, nonionic surfactants are generally liquid at room temperature, and there is a concern that the nonionic surfactant exudes from the nonionic granular detergent product into the detergent container. When the nonionic surfactant oozes out into the detergent container, the product appearance may be deteriorated, the detergency may be reduced due to the reduction of the nonionic surfactant in the container contact portion, and the fluidity of the detergent particles and the caking resistance may be adversely affected. is expected.

In Japanese Patent Laid-Open No. 339898/1992, 5-20% of an amorphous oil-absorbing carrier is blended to improve the exudation of a nonionic surfactant, but this component is powdery. Severely, when a large amount is mixed in a detergent, there is a problem that a large amount of dust is generated at the time of manufacturing and during use during washing, resulting in deterioration of workability and discomfort due to "sneezing".

Further, Japanese Patent Application Laid-Open No. 4-502423 proposes a production method in which a nonionic surfactant is gelled and used, but this method is a realistic method because it causes a problem of transferring a gelled product. Absent.

[0006]
