Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel massage material and a pack material.

[0002]

2. Description of the Related Art Conventionally, gel cosmetics such as massage materials and pack materials are known to contain a high concentration of glycerin in order to provide warm feeling and spinnability (Japanese Patent Laid-Open No. 61-161).
No. 210). For the gelation of glycerin, a water-soluble polymer such as carboxyvinyl polymer is mainly used.

The massage charge has a basic function of a moisturizing effect (effect of giving water on the skin surface to the skin),
It is desirable that the cleaning effect and the blood circulation promoting effect are excellent, but these effects cannot be expected in the above-mentioned gel cosmetic containing high concentration glycerin. In addition, it is difficult to give a slippery feel like a massage charge when used. Further, it is difficult to stably mix an emollient oil (an oil for keeping moisture on the skin surface to prevent evaporation) or an oil-soluble rough skin improving component such as vitamin E.

On the other hand, it is desirable that the pack material has a blood circulation promoting effect and a cleansing effect by absorbing excess sebum. These are based on the skin-occluding action, but in the conventional formulation of a gel composition containing a high concentration of glycerin, the skin is not treated. It is difficult to have a blocking effect.

[0005]

The present invention has been made from the above viewpoint, and is a glycerin-containing gel,
Providing a massage charge with excellent moisturizing effect, cleansing effect and blood circulation promoting effect, and also providing a pack charge with an excellent feeling of skin blockage. It is an object of the present invention to provide a massage / pack material which, when used, has a warm feeling while having a feel similar to that of a massage material, and can give a feeling of blockage of the skin when used in a pack.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventor has found that monoglycerin fatty acid ester was used in place of the water-soluble polymer that was conventionally used for gelation of glycerin. By using sucrose fatty acid ester, a moisturizing effect, a cleansing effect and a blood circulation promoting effect can be obtained, and by blending a fatty acid and a higher alcohol, a feeling of blockage can be obtained, and further, emollient oil and oil-soluble rough skin are improved. The inventors have found that the components can be blended in a stable manner and have completed the present invention.
