DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external preparation for skin containing a spherical powder of calcium alginate. More specifically, it absorbs perspiration during perspiration, suppresses the stickiness and perspiration of the skin, and has a very good usability. The present invention relates to an antiperspirant / deodorant having makeup durability and a makeup cosmetic.

[0002]

2. Description of the Related Art In the case of antiperspirants and deodorants, powder cosmetics such as talcum powder, deodorant powder and powder spray have been used in order to suppress stickiness and sweating of the skin during perspiration. Talc is most often used as the main component of these powder cosmetics, and other components having an antiperspirant effect, such as aluminum hydroxychloride and zinc oxide, have been added. In makeup makeup, powder cosmetics such as foundation, powdered white powder, blusher, eyeshadow, and lipstick have been used. The main components of these powder cosmetics are extender pigments such as mica, talc, sericite, and nylon powder; white pigments (ultraviolet protection powder) such as titanium oxide and zinc oxide; coloring pigments such as iron oxide chromium oxide; Pearl agents such as titanium, colored mica, nylon, polyethylene, cellulose,
Spherical organic powders such as chitin and chitosan (usability improvers)
Has been formulated.

[0003]

[Problems to be solved by the invention]
In deodorants, talc itself has low adhesion to skin, and is often used in combination with metal soap or the like to improve adhesion. However, when used in combination with a metal soap, there is a problem that the lipophilicity increases and the water absorption decreases, and the effect of suppressing sweating decreases. In make-up cosmetics, all extender pigments, white pigments, coloring pigments, pearling agents, etc. lack water resistance, so surface treatment with silicone etc. improves water resistance during perspiration, but water absorption is reduced Therefore, a refreshing feel cannot be obtained on the skin.
Further, the spherical organic powder has no water absorbing power in nylon, polyethylene and the like, and has a water absorbing power in cellulose, chitin, chitosan and the like, but has a problem that it swells and sticks remarkably.

On the other hand, an example in which a spherical powder of calcium alginate is applied to cosmetics is a skin cosmetic having a massage effect, a cleansing effect, and a skin conditioning effect (JP-A-63-13910).
8) is known, but the calcium alginate used here is a hydrate of 60 to 90% by weight and has a particle size of 0.05 to 5 mm. It has no effect of suppressing skin stickiness or improving makeup lasting. As described above, an object of the present invention is to provide a skin external preparation excellent in usability while suppressing stickiness and sweating of the skin during perspiration. The present inventors have conducted intensive studies to achieve the above object, and as a result, by adding a specific calcium alginate spherical powder to an external preparation for the skin, absorbs sweat at the time of perspiration, suppresses stickiness and sweating of the skin, The present inventors have found that an antiperspirant / deodorant and a makeup cosmetic having very good usability and long lasting makeup can be obtained, and have completed the present invention.

[0005]

Means for Solving the Problems The invention according to claim 1 is a skin external preparation characterized by containing a calcium alginate spherical powder having a particle diameter of 20 μm or less. The invention according to claim 2 is the skin external preparation according to claim 1, wherein the water content of the calcium alginate spherical powder is 20 wt% or less. The invention according to claim 3 is the skin external preparation according to claim 1 or 2, wherein the skin external preparation is an antiperspirant / deodorant. The invention according to claim 4 is the skin external preparation according to claim 1 or 2, wherein the skin external preparation is a makeup cosmetic.
Hereinafter, the configuration of the present invention will be described in detail.

[0006]

DETAILED DESCRIPTION OF THE CONFIGURATION The calcium alginate spherical powder used in the present invention preferably has a particle diameter of 20 μm or less, and particularly preferably has a water content of 20 wt% or less. Particle size is 20μm
Those exceeding are unfavorable because they feel rough when used. Further, those having a water content exceeding 20% by weight are not preferable because they do not show sufficient water absorption. The particle diameter is 1 μm
If it is less than 1 μm, the sliding property on the skin deteriorates, so that it is preferably 1 μm or more. Further, it is generally said that powder having a size of less than 1 μm is not preferable because it may fly into the air and reach the lungs when inhaled by a human.

Among the external preparations for skin of the present invention, antiperspirant
The effect is particularly exhibited in deodorants and makeup cosmetics. As antiperspirant / deodorant, deodorant spray, deodorant powder, deodorant stick,
Pressed powder, cream, roll-on, etc. are listed, but in order to sufficiently exhibit the properties of calcium alginate spherical powder, water is not included in the formulation of deodorant spray, deodorant powder, pressed powder, etc., and the mixing ratio of the powder is large Are preferred. On the other hand, make-up cosmetics include white powder, powder foundation, dual-use foundation, oily foundation, blusher, eyeshadow, eyeliner, eyebrow ink, and the like.However, in order to sufficiently exhibit the characteristics of calcium alginate spherical powder, white powder, powder It is preferable that the formulation of the foundation, the dual-use foundation, the blusher, the eye shadow, the eye liner, the eyebrow, etc. does not contain water and has a large powder mixing ratio.

Although there is no particular limitation on the compounding amount, it is preferably 1
It is at least 5% by weight (in the case of a spray, based on the balance excluding the propellant), and more preferably at least 5% by weight (in the case of a spray, based on the balance excluding the propellant). 1wt
%, The effect of suppressing the stickiness and sweating of the skin is not exhibited, and the usability on the skin is poor.

[0009] In addition to the calcium alginate spherical powder, components commonly used in cosmetics, quasi-drugs and the like can be added to the external preparation for skin of the present invention. Examples of such components include powder components, oil components, surfactants, alcohols, water-soluble polymers, ultraviolet absorbers, humectants, and thickeners.

【Example】

(1) Production Example 60 g of sodium alginate (Duck Algin NSPLL: Kibun Food Chemifa Co., Ltd.) and 60 g of sucrose (special reagent grade) were added to 6 l of water and stirred, and sodium alginate and sucrose were dissolved. Bubbling occurred, and bubbles in the aqueous solution were removed. The solution viscosity at this time was measured with an ultrasonic viscometer Viscomate (Model VM-1A, manufactured by Yamaichi Electric Co., Ltd.) and found to be 26.6 cP. The aqueous solution was spray-dried using a spray drier (Ashizawa Niro Atomizer Co., Ltd., mobile minor type) to obtain spherical sodium alginate / sucrose composite particles. Its average particle size is 3.54 μm,
The maximum particle size was 16.75 μm. To 62 g of the spherical sodium alginate / sucrose composite particles thus obtained, 200 ml of isopropyl alcohol was added, and an ultra disperser (LK manufactured by Yamato Scientific Co., Ltd.) was added.
(22 type), and the spherical sodium alginate / sucrose composite particles were dispersed in isopropyl alcohol. This dispersion was poured into 500 ml of a 20% by weight aqueous solution of calcium chloride at 20 ° C. with stirring, and stirred for 1 hour with a magnetic stirrer to crosslink sodium alginate with calcium ions. Next, this dispersion was filtered through a glass filter, and the precipitate was dispersed in 200 ml of water. This was placed in a cellulose dialysis tube, and dialyzed in running water for 3 days. After filtration with a glass filter, 20
In addition to 0 ml of isopropyl alcohol, the mixture was stirred with an ultra disperser for 10 seconds to disperse the particles and allowed to stand for 1 hour. It was again filtered with a glass filter and dried under reduced pressure at 60 ° C. Table 1 shows the physical properties of the spherical calcium alginate particles thus obtained.
