Oil, in the packaging body containing composition obtained by housing a composition comprising a surfactant to the synthetic resin package, the surface tension of the inner layer of synthetic resin and r _p, the water constituting the composition comprises a surfactant the surface tension of the layer and r _r, when the surface tension of the layer made of the oil constituting the composition was r _0, a r _p> r _r, and packaging body containing satisfying the r _p> r ₀ A composition is disclosed.

[0004] However, Japanese Patent Laid-Open Publication No.
Each publication except Publication 7 discloses a cosmetic containing a fragrance, an antiperspirant component, a powder, etc., but there is no description that the container is made transparent, and furthermore, However, it is not possible to ensure the stability of the deodorant fragrance due to the decomposition and alteration of the above-mentioned composition components that occur when the composition is made transparent, and to satisfy the cosmetic appearance. Further, as described in JP-A-4-308747,
Water, oil, in a packaged composition containing a composition comprising a surfactant in a synthetic resin package, by making the surface tension of each layer of the synthetic resin and the composition of the package a specific relationship, Although it is intended to demonstrate the stable storage of the composition, this technology also does not recognize the above-mentioned technical problem when the container is made transparent, and the decomposition and alteration of the composition components that occur when the container is made transparent. Cannot ensure the stability of the deodorant flavor and satisfy the cosmetic appearance.

It is desirable to have a package having a transmittance of 70% or more. When the package is coated or blended with an ultraviolet absorbing component, the stability of the perfume can be further ensured, and the cosmetic appearance can be further satisfied.

[0013] The antiperspirant composition thus constituted can be used in a single-layer or multi-layer package having a parallel light transmittance of 70% or more.
An antiperspirant component containing at least an antiperspirant component and a fragrance,
Since the composition comprising a water-insoluble powder having a specific gravity of 0.9 to 4.0 is stored, the antiperspirant component and the like are stored in a package such as a transparent container. In addition, the composition components are not decomposed or deteriorated by visible light and ultraviolet light, the stability of the deodorant flavor is ensured, and the cosmetic appearance can be satisfied. That is, conventionally, when an antiperspirant component or the like is stored in a transparent container or the like, the metal component derived from the active ingredient of the antiperspirant and the astringent component content powder triggers a catalytic action, and the composition component There is a problem that it is difficult to ensure the stability of the deodorant fragrance and to satisfy the cosmetic appearance, mainly due to the decomposition and deterioration of the cosmetic. The essence of these causes is typically an oxidation reaction, a hydrolysis reaction, a Maillard reaction, etc., but in any case, some of the antiperspirant components accelerate the transfer and transfer of electrons at the molecular level and become active. It is speculated that the reaction may proceed to cross the mountain of chemical energy. In the present invention, when a powder having specific physical properties is simultaneously mixed with an antiperspirant component, a part of the antiperspirant component is adsorbed due to the surface adsorption or incorporation of the powder due to the presence of the powder having the specific physical properties. The transfer and transfer of the powder will be completed with the powder, as a result, the decomposition and deterioration of useful ingredients such as fragrances and activators and ester oils will be avoided,
Even when the antiperspirant components etc. are stored in a package such as a transparent container, the composition components are not decomposed or deteriorated by visible light and ultraviolet light, and the stability of the deodorant flavor is ensured.
In addition, the cosmetic appearance can be satisfied.
