Description

The present invention mainly relates to an effervescent detergent composition having a high cleaning effect on stains in beverage / food manufacturing factories and kitchens and an excellent adhesive effect on a vertical surface.

Dirt such as proteins and oils adheres to the floors and walls of kitchens such as beverage and food manufacturing and processing factories, hotels, restaurants, etc., and oil stains that have been altered by heat cannot be easily removed. Moreover, in smoked houses that manufacture smoked products, along with oil stains, altered tar content firmly adheres to the wall surface, making cleaning difficult. Various strongly alkaline liquid cleaning agents have been proposed for removing oil stains, and 25% or more of caustic soda and / or caustic potash and water-soluble substances such as anionic surfactants, hydroxycarboxylic acids, aminocarboxylic acids and salts thereof. Strong alkaline liquid cleaning agent composition containing a sex polymer chelating agent, an alkyl ether sulfate, etc. (Patent Document 1), along with 10 to 30% by mass of an alkali metal hydroxide salt, α-olefin sulfonate, monoalkyl glucoside, A liquid cleaning agent composition containing a polyhydric alcohol (Patent Document 2) and the like have been proposed.

When a monoalkyl glucoside is used instead of the alkyl polyglucoside of the component (D), it is difficult to solubilize the anionic surfactant of the component (B), but the alkyl polyglucoside is used as the component (D). Even when used, if the average degree of polymerization is less than 1.2, the solubilization of the component (B) may be insufficient. Therefore, the alkylpolyglucoside of the component (D) has an average degree of polymerization of 1.2. It is preferable to use the above. The ratio of the component (D) in the foaming detergent composition is preferably 0.1% by mass or more and 5% by mass or less.
