Description

  The present invention relates to a foamable solid detergent. More specifically, the present invention relates to a foamable solid detergent that can be produced efficiently and has high hardness.

  Conventionally, foaming detergents containing foaming agents can exert excellent cleaning action due to the interaction between chemical cleaning power by surfactants and physical cleaning power by foaming action, so dentures, glasses, drain pipes, Widely used for washing sinks, washing tubs, toilets, bathtubs, stainless steel bottles, etc. In addition, effervescent detergents are provided in various solid forms such as tablets and granules, but among these forms, tablets are easy to handle and are widely accepted by consumers. ing.

  Generally, foaming detergents are blended with components such as bleaching agents, surfactants, bactericides, fragrances, deodorants, etc., depending on the purpose of use and the cleaning action to be provided. Moreover, since it is necessary to mix | blend a comparatively large amount of foaming agents with a foaming detergent in order to ensure foamability, in a foaming detergent, there exists a characteristic on a composition that the ratio of a foaming agent is high. .

  On the other hand, effervescent solid detergents such as tablets and granules are required to have high hardness in order to prevent cracking and chipping during packaging or transportation. In addition, in the case of tablet-like and granular foamable solid detergents, in order to increase productivity, the raw material mixture used for tableting and granulation must be fluid (that is, molding such as tableting and granulation). It is also important to have a characteristic that is easy to do. However, as described above, the foamable solid detergent has a compositional characteristic that the ratio of the foaming agent is large. Therefore, when it is formulated into a solid form such as a tablet or granule, the solid after molding There is a drawback that it is difficult to provide (tablets and granules) with sufficient hardness.

  Conventionally, various techniques for producing foamable solid detergents have been reported. For example, Patent Document 1 discloses that an organic acid that does not substantially contain water or does not liberate crystal water at 50 ° C. or less and polyethylene glycol are heated and melted and mixed at 60 to 100 ° C., and then stirred under predetermined conditions. While cooling and pulverizing, adding sodium bicarbonate and sodium carbonate to this and molding into tablets, reducing the amount of stabilizers, binders, mold release agents, etc. It has been reported that foaming detergents can be obtained. However, Patent Document 1 does not disclose a formulation technique for providing the foamable solid detergent with sufficient hardness.
