Description

  The present invention comprises (a) sodium polyacrylate, and (b) powder, so that it has a mousse shape, substantially contains no oil, and is smooth and light. The present invention relates to a water-based cosmetic with excellent properties. In addition, it contains (a) sodium polyacrylate, (b) powder, and (c) fatty acid soap, so it has a marshmallow-like shape, and it is solid and easy to use. A marshmallow O / W solid that has a characteristic of changing to a mousse when water is dropped onto the surface of the O / W solid cosmetic with excellent refreshing feeling and adhesion Regarding cosmetics.

  Conventionally, as a cosmetic containing bubbles, a whipped cosmetic containing a specific oil (Patent Document 1), a bubble-containing cosmetic containing gellan gum (Patent Document 2), and a whipped O / W containing a gelling agent. Type emulsified cosmetics (Patent Documents 3 to 4) Whipped aqueous cosmetics (Patent Document 5) containing hydrophobized silicic anhydride have been proposed. The mousse-like and marshmallow-like products filled in the containers in the state of containing these bubbles have a unique feeling of use that is smooth and light, and thus have been developed not only in the food field but also in the cosmetic field.

Patent 1473460 JP 2000-355517 A JP 2002-145720 A JP2002-145734 JP 2004-59456 A

  Conventional bubble-containing cosmetics are oily or O / W emulsified cosmetics containing a specific oil or surfactant, and are not satisfactory in terms of a refreshing feeling and a light feeling. Further, even the foam-containing aqueous cosmetics must contain hydrophobized silicic acid anhydride, which is not satisfactory in terms of smooth use feeling and adhesion. Also, oily, particularly oily or O / W type solid emulsified cosmetics containing a high melting point wax and a surfactant, while maintaining the convenience of being solid and sufficiently smooth and light in use, refreshing, No one satisfying the adhesion has been obtained yet.

  Therefore, as a result of intensive studies, the present inventor has (a) sodium polyacrylate and (b) powder, so that it has a mousse shape without containing any oil, and is smooth and light. It is possible to obtain a water-based cosmetic excellent in feeling of use, refreshing feeling, and adhesion, and further, by containing (a) sodium polyacrylate, (b) powder, and (c) fatty acid soap, In addition to the convenience of being solid, it is possible to obtain a marshmallow O / W type solid cosmetic with a smooth and light unique feeling of use, a refreshing feeling, and excellent adhesion, and when water is dropped on its surface, The present inventors have found that the portion changes like a mousse and have completed the present invention.

  That is, the present invention comprises (a) sodium polyacrylate and (b) powder, so that it has a mousse shape and contains a smooth, light, unique feeling of use and coolness, substantially containing no oil. , A water-based cosmetic with excellent adhesion, and (a) sodium polyacrylate, (b) powder, and (c) a fatty acid soap so that it has a marshmallow shape and is simple and solid. In addition to the properties, it is possible to obtain O / W type solid cosmetics that are smooth and light and have a unique feeling of use, coolness and adhesion, and when the water is dropped on the surface, the part changes to a mousse shape. It is a marshmallow O / W type solid cosmetic having the properties of

  As described above, the mousse-like water-based cosmetic containing substantially no oil by containing (a) sodium polyacrylate and (b) powder is smooth and light and has a unique feeling of use, refreshing The marshmallow-like O / W type solid cosmetic containing (a) sodium polyacrylate, (b) powder, and (c) fatty acid soap is water on its surface. It is clear that when it is dripped, the part has the characteristic of changing to a mousse shape, and while maintaining the convenience of being solid, it is clear that it has a smooth and light unique feeling of use, coolness, and adhesion. is there.
