Abstract

PROBLEM TO BE SOLVED: To obtain a powdery skin lotion for bodies, having a refreshing feeling caused by a lower alcohol when applied to the skin, capable of blending a large amount of a powder and rich in powdery feeling by blending a remarkable amount of the lower alcohol with the specific powder. SOLUTION: This powdery skin lotion for bodies is obtained by blending a lower alcohol such as methanol or ethanol with a porous and/or a water absorbing powders such as corn starch. The amount of the blended lower alcohol is 50.0-95.0wt.%, preferably >=60wt.% and that of the blended porous and/or water absorbing powders is 5.0-30.0wt.%, preferably 10.0-20.0wt.%. The powders are preferably potato starch or silicic acid anhydride in addition to that described above. A perfume is preferably further blended in the system. The perfume is blended in an amount of 0.5-30wt.%, preferably 1.0-10.0wt.%.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder lotion for a body, and more particularly to a powder lotion for a body which has a refreshing feel when applied to the skin and which gives a dry and smooth powdery feel. This powder lotion for body can be applied to basic cosmetics by adding a moisturizing agent, or can be used as a coating type fragrance cosmetic by adding an appropriate fragrance to the cosmetics.

2. Description of the Related Art Conventionally, the technology of incorporating powder into cosmetics has been known to clean the skin by allowing the powder to absorb components such as dirt on skin, excess lipid, and sweat. In addition, it has been widely used for the purpose of enhancing sebum resistance and perspiration resistance due to its absorption effect, improving makeup retention, or enhancing the feeling of use by utilizing its dry feel. For example, as a lotion, there is a lotion containing calamine (zinc oxide containing about 0.5% ferric oxide), which is more commonly used as a summer lotion having a drying, cooling and protecting effect. ing.
However, since it is basically intended for moisturizing or astringent, the feeling of use has not been considered so much. In addition, in reality, a large amount of powder cannot be blended in view of the balance of emulsification, so that it has not been possible to impart a dry feel, and the refreshing feel was not satisfactory. On the other hand, baby powder and talcum powder are known as powder cosmetics for the body, which is used for the whole body after bathing in the summer or after shaving and gives a dry feel to the skin and absorbs sweat and moisture. ing. Further, a dusting powder for the purpose of perfuming the skin by adding a fragrance to the powder is also known. However, these powdery cosmetics for body used for dusting have a problem in that they are inconvenient in terms of usability, such as scattering of powder and soiling of clothes and peripheral parts. Further, the refreshing feeling on the skin was not yet satisfactory.

The present invention has been made in view of the above conventional circumstances, and is a powder cosmetic for the whole body,
An object of the present invention is to provide a powdery lotion for a body which has a refreshing feeling and has a dry feel.

[0004]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that if a considerable amount of a lower alcohol and a porous and / or water-absorbing powder such as corn starch are blended, it will not affect the skin. It has been found that when applied, it has a refreshing sensation due to lower alcohol, and a large amount of powder can be blended, so that a powder lotion for body which is rich in powdery feeling can be obtained.

That is, the present invention is a powder lotion for a body, which is characterized by blending a lower alcohol and a porous and / or water-absorbing powder.

Next, the structure of the present invention will be described. Examples of the lower alcohol used in the present invention include methanol, ethanol, propanol, isopropanol, isobutyl alcohol, t-butyl alcohol and the like. Of these, ethanol is particularly preferable. The blending amount is 50.0 to 95.0% by weight in the total amount of the lotion,
It is preferably 60.0% by weight or more. When the amount of lower alcohol is less than 50.0% by weight, it is difficult to obtain a satisfactory refreshing feeling. In this way, by adding a large amount of lower alcohol, when applied to the skin, the heat of vaporization during evaporation of the lower alcohol imparts a refreshing feeling to the skin, and after application, the lower alcohol component evaporates soon. By leaving a considerable amount of powder components on the skin, a dry feel is imparted to the skin.

The porous and / or water-absorbing powder used in the present invention includes starches obtained from corn and potato, silicic acid anhydride, talc, kaolin, magnesium aluminate silicate, magnesium aluminometasilicate. , Calcium alginate, synthetic and natural hectorite, bentonite and other powders. Among these, the most preferable powders from the viewpoint of usability are corn starch, potato starch and silicic acid anhydride, and corn starch is particularly preferable. The blending amount is 5.0 to 30.0% by weight, and preferably,
It is 10.0 to 20.0% by weight. If the content of the porous and / or water-absorbing powder is less than 5.0% by weight, the feeling of powder after application to the skin will be poor, and if it is more than 30.0% by weight, the powder will be distorted during application to the skin.

The body powder lotion of the present invention is made into an aroma composition for the purpose of perfuming the skin by adding a perfume in addition to a lower alcohol, a porous and / or water-absorbing powder. Can be applied. As the flavor in this case, any of animal-based, plant-based, mineral-based natural flavors and synthetic flavors can be used. The blending amount of the fragrance is such that a sufficient fragrance can be obtained as a fragrance product,
Generally, it is 0.5 to 30.0% by weight, preferably 1.0 to 10.0% by weight.

The powder lotion for body as used in the present invention means a lotion used for the purpose of skin conditioning, protection, activation, etc. of the skin of the face, hands, neck, feet, scalp and the like.

In addition to the above components, the cosmetic of the present invention contains
Oils, surfactants, polymer compounds, water, preservatives and other components that are usually blended in lotion can be blended as appropriate according to the intended use and purpose.
