Description

  The present invention relates to an aerosol-type deodorant composition.

  Conventionally, many deodorant compositions have been developed to suppress the generation of body odors such as axillary odor and foot odor. As the dosage form of the deodorant composition, for example, a roll-on type, an aerosol type, a mist type, a lotion type, a stick type, a cream type and the like are known. Among these, the aerosol type deodorant composition is excellent in the feeling of dry skin immediately after spray application and the deodorizing effect immediately after spray application. However, the aerosol-type deodorant composition has a problem that when sweating is considerably increased after spray application, the skin becomes sticky, the skin feels dry, and the deodorizing effect cannot be maintained.

  In order to solve such problems, powder aerosol cosmetics have been proposed which suppress the stickiness of the skin after perspiration, maintain the dry feeling of the skin, and have excellent whiteness on the skin immediately after spray application. (For example, see Patent Document 1). In addition, a deodorant agent for a human body that has a deodorizing effect and has no white residue on the skin immediately after spray application has been proposed (for example, see Patent Documents 2 and 3). However, these proposals are particularly concerned with the persistence of the dry feeling of the skin and the persistence of the deodorant effect after sweating, and the dry feeling of the skin immediately after the spray application, the deodorant effect immediately after the spray application, and immediately after the spray application. The lack of white residue on the skin is insufficient, and further improvement and development are desired.

  Therefore, it is excellent in persistence of dry skin feeling after sweating, persistence of deodorant effect after sweating, skin dry feeling immediately after spray application, and deodorant effect immediately after spray application, and skin immediately after spray application. It is desired to provide an aerosol-type deodorant composition having no white residue on the surface.

<No white residue on skin immediately after spray application>
Twenty professional panelists in their twenties to fifties (ten women, ten men) placed the aerosol-type deodorant compositions of Examples 1 to 29 and Comparative Examples 1 to 7 on the inner forearm, 10 cm away from the skin. From this position, three reciprocal spray coatings (about 0.2 g) were performed in a length direction of 10 cm. Immediately after the spray application, “the absence of white residue on the skin immediately after the spray application” was evaluated based on the following evaluation criteria.
