Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent having a massage effect and an excellent detergency by foaming carbon dioxide gas.

[0002]

2. Description of the Related Art For the purpose of simultaneously obtaining a cleaning effect and a massage effect, there has been known a massage cleaning agent in which a crude drug such as a pepper extract or a seaweed extract or a scrubbing agent is mixed in the cleaning agent. However, the massage effect of these cleaning agents is low, and since it is necessary to perform massage while washing for a long time, the sebum is excessively washed out, causing skin roughness.

On the other hand, as a composition for obtaining a massage effect by foaming carbon dioxide gas, foaming cosmetics and bath agent compositions (JP-A-4-217609, JP-A-5-22)
Nos. 9933 and 6-56646) are known. However, in these conventional effervescent cosmetics, basically, carbon dioxide is generated by a reaction between a carbonate and an acid. Under such conditions, ordinary surfactants such as fatty acid soap lose their surface activity and the foaming power is reduced, and sufficient foaming property, foam persistence and detergency cannot be obtained. There was a problem.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a detergent having a massage effect by foaming carbon dioxide gas, and a detergency and foaming (persistence) by a surfactant.

[0005]

The inventors of the present invention have studied the generation of carbon dioxide and the performance of the surfactant. As a result, if a powdery salt-resistant surfactant was added to the carbonate and the acid, it could be stored during storage. The present inventors have found that a composition capable of suppressing the reaction between a carbonate and an acid and having excellent foaming properties, detergency and a massage effect when used can be obtained, and completed the present invention.

That is, the present invention provides a detergent composition containing a carbonate, an acid and a powdery salt-resistant surfactant.

[0007]

It is more than ml. The aqueous solution at the end of foaming is
It is necessary that the conditions be pH 3 to 6.5. Further, the reason why the powder is in the form of a powder at normal temperature is that otherwise, the carbonate and the acid react during storage. As a surfactant having a foaming property even under such carbon dioxide generation conditions,
