Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a foamed tablet detergent having improved storage stability.

[0002]

2. Description of the Related Art Water-soluble solid alkalis and acids are used in commonly used effervescent tablet detergents. In general, sodium bicarbonate is used as an alkali, tartaric acid, citric acid, succinic acid, malic acid, and sulfamic acid are used as organic acids and acids such as boric acid are used as inorganic acids.

[0003] In addition to these components, ionic and nonionic surfactants are used as detergent components, and polysaccharides and glycols are used as binders for forming tablets. Enzymes, fragrances and the like are commonly used.

In the foaming reaction, carbon dioxide gas is generated by a reaction between a carbonate such as sodium hydrogen carbonate and an acid, and this reaction requires the presence of moisture. Since even a very small amount of water causes a reaction and carbon dioxide gas is generated, anhydrous is usually used as a raw material, and the production environment is usually
Pressing must be performed in an environment of a temperature of 20 ° C. and a humidity of 20 ± 10%.

[0005] When a raw material containing water is used or production is performed in an environment with high humidity, the product gradually collapses due to the generation of carbon dioxide due to the reaction, and the individual packaging of the product bulges and ruptures. However, there is a problem in that foam cleaning properties are lost and the value as a product is lost.

It is also known as a known fact that an anhydrous sodium aluminate is added as a dehydrating agent inside a tablet to a foaming tablet bath agent (Japanese Patent Laid-Open No. 59-70610).
issue). However, sodium aluminate reacts with an anionic surfactant as a detergent, generates an aluminum salt, and becomes insoluble in water. I will.

Therefore, in the present invention, a room temperature of 30.degree.
%, Which has a good cleaning ability even when manufactured in an environment of high%, and aims to provide a stable foaming tablet detergent that does not cause deterioration like conventional products even in a high temperature environment for a long time. is there.
