Description

FIELD OF THE INVENTION The present invention relates to foaming cleaning compositions.

BACKGROUND ART Single-component foaming cleaning agents for the human body that generate carbon dioxide gas when used are known (Patent Documents 1 and 2). These foaming cleaning agents are in the form of powder or granules containing a carbonate and an organic acid, and when water is added, the carbonate and the organic acid react to generate carbon dioxide gas.
In foaming cleaning agents, it is necessary to mix carbonate and organic acid in high amounts in order to sufficiently generate carbon dioxide gas. However, carbonates such as sodium carbonate and sodium bicarbonate, and organic acids such as citric acid and malic acid, which are commonly used in foaming cleaning agents, are highly hygroscopic and may form lumps. In addition, foaming may start unexpectedly due to moisture absorption or high temperature during storage, so it is desired to provide a foaming cleaning composition that has sufficient foaming properties and has excellent moisture resistance and high temperature stability. ing.

The foaming cleaning compositions of Examples 1 to 17 of the present invention had excellent moisture resistance and high temperature stability. The composition of Comparative Example 5 also has excellent moisture resistance and high temperature stability, but this is because it does not contain (A) carbonate and (B) organic acid. On the other hand, the foaming cleaning compositions of Comparative Examples 1 to 3, which did not satisfy the composition of the present invention, had poor moisture resistance, and the foaming cleaning composition of Comparative Example 4 had poor moisture resistance and high temperature stability.
From the results of Examples 1 to 17 and Comparative Examples 1 to 4, it was found that by including (C) acyl isethionate as an activator in a specific amount relative to the total of (A) carbonate and (B) organic acid, moisture resistance, It was confirmed that a foaming detergent composition with excellent high temperature stability could be obtained.
From the results of Example 8 and Comparative Example 5, it was confirmed that (A) carbonate and (B) organic acid made (C) acylisethionate easy to dissolve and foam.

(Product evaluation)
A comparative evaluation was conducted between Example 5, which is the present invention, and commercially available cleaning agents 1 to 4 containing (A) carbonate and (B) organic acid. Note that commercial product 3 is a product that claims to be non-foaming, and only commercial product 4 contains (C) cocoyl isethionate. However, commercially available product 4 contains lauroyl glutamate as the main active agent, although the detailed blending amount is unknown.
In addition to the above evaluation items, carbon dioxide concentration was measured. The results are shown in Table 2.
(5) Measurement of carbon dioxide concentration 0.5 g of the test sample was added to 49.5 g of water and dissolved. After that, while stirring using a magnetic stirrer, measure the carbon dioxide concentration using a portable carbon dioxide measuring device CGP-31 (manufactured by DKK Toa Co., Ltd.), stir for 5 minutes, and check the value. The measured value was taken when it stabilized.

The foaming detergent composition of Example 5, which is the present invention, had excellent moisture resistance compared to commercially available foaming detergents. Commercial product 4 contained (C) cocoyl isethionate, but had poor moisture resistance. This is because commercial product 4 uses lauroyl glutamate as the main active agent, so the sum of (A) and (B) and the mass ratio of (C) ((A) + (B): (C)) are It is assumed that this is because it is outside the range of . This is indirectly supported by the fact that the results of the usability evaluation of Commercial Product 4 are similar to those of Comparative Examples 1 and 2.
