Description

  The present invention relates to a foam cleaning composition, and a foam cleaning agent. More specifically, the present invention relates to a foam cleaning composition that forms foam with a non-aerosol 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.

  Conventionally, the dosage form of the cleaning agent has been mainly solid or liquid. In recent years, it is easy to obtain creamy foam by simply pressing the pump, etc., and because it is excellent in usability, foam that forms foam with non-aerosol type foam discharge containers such as squeeze foamers and pump foamers State-of-the-art cleaning agents are widely used for various purposes such as hand washing, face washing, and hair washing.

  These foam-like cleaning agents are characterized in that the composition and air are mixed to form a foam by passing through a porous film inside a container such as a squeeze foamer or a pump foamer. However, since it is necessary to pass through the porous film in order to form bubbles, there is a problem that the content composition is clogged with the porous film and discharge failure is likely to occur. In particular, when an anionic surfactant excellent in detergency and foaming power, especially a higher fatty acid salt is used, the stability of the preparation is deteriorated during low-temperature storage, and the frequency of clogging tends to increase.

  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, although these attempts can improve the clogging of the porous membrane to some extent, there is still a problem that the stability of the preparation is inferior, and the clogging of the porous membrane has not yet been suppressed. It is not satisfactory.
