Generally, when an organic acid is coexisting with an alkaline salt such as baking soda for the purpose of foaming (7), the stability of the organic acid deteriorates due to the neutralization reaction of the contact area. If the organic acid coexists with the oxidizing agent, the decomposition of the oxidizing agent will be accelerated and the stability of the oxidizing agent will deteriorate.For example, in the past, organic acids and baking soda were commonly used in bath additives, bath water cleaners, bath kettle cleaners, etc. However, if organic acid and baking soda are combined as is, a reaction occurs due to moisture in the raw materials, moisture absorption, etc., and CO2 gas is generated, which may cause the packaging to become stiff or cause problems during use. There were drawbacks such as a decrease in foamability.

To prevent these phenomena, it is possible to coat with organic acid powder, but if it is coated with something that is not water-soluble, it cannot actually be used in water, and if it is coated with only organic matter, it will not work. ,・Since the reaction between this organic substance and other components coexisting at the same time must be considered, it cannot be said to be widely applicable.

According to the present invention, the organic acid powder, which is solid at room temperature, is double coated with a water-soluble organic substance such as polyethylene glycol and a chemically inert organic or inorganic powder. For example, when the organic acid produced is mixed with an alkaline substance such as baking soda to form a blowing agent composition, the presence of inert powder between the baking soda and the organic acid prevents contact and prevents CO2 gas from coming into contact with the organic acid. No generation or deterioration of foaming properties occurs. Moreover, since water-soluble organic substances are used as binders in the present invention, they easily dissolve in water during use.
The powder coated thereon can be dispersed. [Examples] The present invention will be described in more detail below with reference to Examples, but the present invention is not limited to these Examples.

Table [Effects of the Invention] According to the present invention, an organic yeast powder that is stable against alkali, chlorine, and oxygen bleaches can be easily obtained. That is, in the method of the present invention, it is possible to uniformly coat the inert powder even under cooling, and since the coating can be performed at a relatively low temperature, the workability is good and the process can be shortened. The organic acid stabilized according to the present invention can be blended with an alkaline substance such as baking soda to provide a stable blowing agent composition, as shown in the Examples, and can be blended with a bleaching agent to provide a stable blowing agent composition. A stable bleach composition can be provided.
