Description

  The present invention relates to a foam cleaning composition and a foam cleaning agent. Specifically, the present invention relates to a foam cleaning composition that forms foam with a non-aerosol type foam discharge container such as a squeeze foamer or a pump foamer, and a foam cleaning agent that contains the composition in a foam discharge container.

  Although there are solid, liquid, foam, etc., the detergent can be easily obtained by simply pressing the pump, etc., so the foam detergent is suitable for hand washing, face washing, hair washing, etc. Widely used in various applications such as

  This foamy detergent is mixed with the content composition and air by passing through a porous film inside a container such as a pump former to form a foam. However, since it is necessary to pass through the porous membrane for foam formation, there is a problem that the content composition is clogged with the porous membrane. In particular, when an anionic surfactant is used as the surfactant, there is a problem that the preparation stability is deteriorated during low-temperature storage and clogging is likely to occur.

  In order to solve such problems, for example, a skin cleansing product (see Patent Document 1) in which a foam discharge container is filled with a sulfate ester surfactant or a sulfonic acid surfactant and an anionic surfactant, sugar Skin cleansing product (see Patent Document 2) filled with foam non-ionic surfactant and anionic surfactant in foam discharge container, aqueous liquid detergent filled with former fatty acid salt and organic acid salt in foam container (Patent Document 3) Have been proposed). However, these attempts have not yet solved the problems such as formulation stability, clogging of the porous membrane, foam quality, foaminess, and feeling of use, and are still not satisfactory.
