Description

  The present invention relates to an aerosol type gel deodorant agent.

  A side odor causing human discomfort is caused by sweat mixed with sebum and broken down by skin bacteria. In the past, deodorant compositions containing antiperspirants have been used to prevent this unpleasant side odor. In addition, the above deodorant composition is filled in a container and used as a deodorant agent. The above deodorant agents are used in various types such as gel, cream, lotion, aerosol, pump and stick.

  The aerosol type deodorant agent is excellent in usability because it can be used by spraying without being applied directly to the application object such as the side, and from the point of being able to give a feeling of coolness to the application object It is also excellent in cleanliness. For this reason, aerosol type deodorants are widely supported and widely used.

  As an aerosol type deodorant agent, an aerosol type liquid deodorant agent which becomes liquid on a sprayed application target is widely used. The aerosol type liquid deodorant agent is excellent in that it can be directly jetted in a wide range, in addition to the above-mentioned superiority, but it has a problem of dripping on the object to be coated and splashing around.

  As a dosage form capable of solving the problems of the aerosol-type liquid deodorant, an aerosol-type gel-like deodorant which is gelled on the object to be jetted has been proposed. According to this formulation, it is possible to suppress dripping on the object to be coated. Furthermore, since it is presupposed that the ink is painted by hand after the injection, it is not necessary to inject in a wide range, and scattering to the surroundings can be suppressed (see Patent Document 1 etc.).

  The deodorant composition generally contains an antiperspirant which is an agent that suppresses the generation of sweat by astringent skin. Among them, zinc paraphenol sulfonate is excellent in antiperspirant action, but when it is added to a water-soluble deodorant composition, there is a problem that precipitates are easily generated, especially when precipitation occurs with an aerosol type deodorant agent, it causes clogging. Problem of becoming

  Patent Document 2 discloses a composition for antiperspirant spray which contains zinc paraphenol sulfonate, is excellent in stability, and has no dripping, but contains a water absorbing resin, so that stickiness is felt at the time of application. There is room for improvement in the feeling of use. In addition, there is no description of making into an aerosol type.
