Description

The present invention relates to a non-hydrous cosmetic containing a particulate antiperspirant component. In particular, the present invention relates to a non-hydrous cosmetic containing a particulate antiperspirant component having a different particle size distribution.

Cosmetics such as antiperspirants are known as antiperspirant products that prevent axillary odor and suppress perspiration by astringent action of pores. As the component contained in the antiperspirant, a particulate component having astringency is mainly used, and it is known that the effect is exhibited by directly acting on pores and the like to suppress the generation of sweat. Has been done.

For example, Patent Document 1 proposes an external preparation for skin containing an antibacterial zeolite and alum and / or alum particles.

<Manufacturing of particulate antiperspirant component (B)>
Add 7 kg, 10 kg, 40 kg, and 80 kg of baked alum (potassium aluminum sulfate: Thai Ace K20: manufactured by Taimei Chemicals Co., Ltd.), respectively, and use a jet mill (Jet Mill STJ-200 manufactured by Seishin Enterprise Co., Ltd.) for 1 hour. , Finely crushed.
FIG. 1 shows a graph showing the particle size distribution of the baked alum particles obtained by adding 10 kg and finely pulverizing the particles. Similarly, FIG. 1 shows the baked alum particles before fine pulverization.
In Table 1, the volume mean diameter (VMD), cumulative 50% particle diameter (D50), cumulative 10% particle diameter (D10), cumulative 90% particle diameter (D90), and cumulative 99 of baked alum particles before and after fine pulverization. % Particle size (D99) is shown.

<Dissolution rate measurement test>
400 g of water was weighed in a 500 mL beaker, and the temperature was raised to 38 ° C. using a hot water bath (220 mm × 290 mm × 40 mm SUS bat) and an immersion heater.
Next, while stirring (500 rpm) using a rotor (25 mm × 8 mmΦ) with a stirrer, the electrode of the EC meter (TOA / DKK CM-25R) is immersed in the liquid surface up to 40 mm from the tip, and then baked alum. 4 g was added, and the change in electrical conductivity (μS / cm) was measured over time. The dissolution rate was calculated from the electric conductivity at each time, assuming that the electric conductivity when the entire amount of 4 g was dissolved was 100%.
Table 2 shows the dissolution rates of baked alum before crushing and baked alum after crushing in water.

From the results in Table 2, it was found that the baked alum particles after crushing were more rapidly dissolved in water than the baked alum particles before crushing. It was also found that the smaller the volume average diameter of the alum particles after crushing, the faster they dissolve in water.
Furthermore, it was found that the baked alum particles after adding 10 kg and crushing were dissolved in water about twice as fast as the baked alum particles before crushing.
From this result, it was found that the pulverized alum particles having a smaller particle diameter can be made more soluble in water such as sweat, and a more immediate antiperspirant effect can be obtained. On the other hand, the baked alum particles before crushing have a larger particle size than the baked alum particles after crushing, and therefore have a slower dissolution rate in water such as sweat than the baked alum particles after crushing, so that they have a highly durable antiperspirant effect. It turned out that it can play.

<Manufacturing of non-hydrous stick type antiperspirant>
A stick-type antiperspirant was produced using the baked alum particles obtained by adding 10 kg and finely pulverizing the particles.
As a production method, those having a high melting point such as fats and oils were melted at 90 ° C., baked alum was added, and the mixture was mixed with a homomixer. After mixing, the mixture was filled in a container and cooled in a refrigerator at 5 ° C. for 24 hours to produce a stick-type antiperspirant having a length of 4 cm and a diameter of 25 mm.

[Prescription example]
Next, an example of a compounding formulation in which the baked alum particles (A) before fine pulverization and the baked alum particles (B) after fine pulverization are used in combination and applied to a stick-type antiperspirant or the like is shown.
