The present invention relates to a cleaning agent for the heating part of a small heat exchanger used in bathtubs, water heaters, central heating, etc. When conventional bathtubs and the like are used for a long period of time, steam, slime, scale, etc. accumulate inside them, reducing their thermal efficiency. Furthermore, when bathing, scales and the like are discharged from the inside of the pot, causing discomfort and being unfavorable from a sanitary standpoint. Conventionally, this type of cleaning agent has been known to contain a hydrogen peroxide compound alone or an inorganic builder such as soda carbonate, bicarbonate of soda, or bicarbonate of soda, and a surfactant, but the cleaning power of these cleaning agents is This is largely due to the foaming power of the decomposed oxygen that is generated when the hydrogen peroxide compound is dissolved in water or hot water. Therefore, if the hydrogen peroxide compound can be foamed and decomposed more rapidly than when it is dissolved in water or hot water. , you can expect stronger cleaning power. Organic acids such as sulfamic acid and citric acid are examples of this kind of foaming and decomposition accelerator, but these compounds extremely deteriorate the storage stability of hydrogen peroxide-added compounds and If you add
It is true that the decomposition of the hydrogen peroxide compound is accelerated, but the foam produced lacks stability. That is, when the hydrogen peroxide admixture comes into contact with water, it immediately decomposes and foams, and the decomposition is completed by the time it reaches the inside of the kettle, making it impossible to achieve a cleaning effect inside the kettle. For these reasons, it is very difficult to commercialize this type of compound as a homogeneous mixture. In view of the above-mentioned circumstances, this invention has been developed to improve foaming promotion and storage stability in a cleaning agent for small heat exchangers such as bathtubs, which contains hydrogen peroxide or an inorganic builder such as soda carbonate or bicarbonate. As a result of extensive research, we have found that by adding one or more types of protein to hydrogen peroxide alone or to a composition in which sodium carbonate or bicarbonate is added, foaming occurs when water is dissolved in hot water. It has been found that the present invention has the ability to promote the development of oxidation, and at the same time has a storage stability comparable to that of conventional products. Examples of the hydrogen peroxide additive used in this invention include sodium percarbonate and sodium perborate. Examples of the protein include amylase, protease, and reverse. The amount of the above compound added is 0.01 to 20.0 wt%, preferably 0.1 wt% or more, based on the hydrogen peroxide adduct. That is, if it is less than 0.01 wt%, no significant effect is observed in terms of promoting foaming, and if it is more than 20.0 wt%, damage to storage stability is observed. On the other hand, when a predetermined amount of the above compound is added to hydrogen peroxide alone or to a mixture with an inorganic builder such as soda carbonate or bicarbonate,
The cleaning agent could be stored in a stable state for a long period of time, and a good cleaning effect could be achieved by putting this cleaning agent into the inside of a bathtub filled with water or hot water. Examples of this invention will be shown below. (1) Foaming decomposition acceleration test Pour 20℃ tap water into beaker 1.
The mixture was stirred at 250 rpm using a lab disper, 5 g of the specimen was added thereto, completely decomposed and dissolved, and the time until foaming ceased was defined as the foaming and decomposition rate. (2) Storage stability test After leaving 5g of the sample in a constant temperature and humidity chamber at 35℃ and 80% RH (relative humidity) for 7 days, the remaining effective oxygen rate (%) in the sample was measured. The stability was compared. The compositions and test results of the formulation examples and comparative examples are shown in the table.

[Table] From the above results, the composition of the present invention has a decomposition promoting effect compared to conventional products containing hydrogen peroxide and an inorganic builder, and has almost the same stability as conventional products. I got something that didn't change. Furthermore, although the decomposition rate of conventional products containing organic acids is extremely fast, it is found that they are not practical in terms of stability.
