Description

Technical Field

[0001] The present invention relates to fragrance products.

Background Art

[0002] Fragrance products such as perfumes and colognes are used for purposes such as scenting, relaxation effects, and masking body odor, and are provided in a form in which a fragrance composition containing a fragrance and alcohol is filled in a spray container or a roll-on container.

[0003] A roll-on container can be directly applied to an application part via a ball without spraying the fragrance composition, prevents adhesion to clothes, etc., and is easy to adjust the application range and the amount of application, so it is used as a container for fragrance products.

[0004] For example, Patent Document 1 describes a fragrance product in which an antiperspirant deodorant composition containing an aldehyde fragrance and ethanol is filled in a roll-on container provided with a polypropylene ball. By using the roll-on container, the antiperspirant deodorant composition can be applied to the skin with high adhesion, and an antiperspirant effect can be exhibited.

[0005] On the other hand, when the alcohol content of the fragrance composition is high, etc., a plastic ball such as polypropylene may be deteriorated, causing liquid leakage. Therefore, a roll-on container provided with a metal ball such as stainless steel that is less likely to deteriorate is used.

[0006] However, when the present inventors stored a fragrance product in which a fragrance composition was housed in a roll-on container provided with a metal ball, colored precipitates were generated in the metal ball portion, and it was confirmed that stains occurred on the application portion when applied.

[0032] As the properties of the fragrance composition, for example, it can be implemented in various forms such as liquid, gel, cream, etc. Among them, it is preferable to use a liquid form in order to obtain the effects of the present invention. Here, the liquid state means a state having fluidity at 25°C. Specifically, it refers to the viscosity measured using a Brookfield type rotational viscometer (rotor No. 2) at 25°C and 1 atm being 20,000 mPa·s or less, preferably 10,000 mPa·s or less, more preferably 5,000 mPa·s or less.

[0033] [Manufacturing method of fragrance composition] The method for producing the fragrance composition is not particularly limited and can be produced by mixing the above essential components and optional components according to a conventional method.

[0034] [Fragrance product] The fragrance product of the present invention is obtained by filling the fragrance composition obtained as described above into a roll-on container. The roll-on container has a stopper that rotatably holds a ball at the container mouth, and by rotating the ball in contact with the contained composition, the composition adhering to the surface of the ball is applied to a desired site. In the present invention, a roll-on container equipped with a metal ball is used. The metal ball is not particularly limited, and examples include stainless steel balls. Although the reason for the formation of precipitates when the fragrance composition is contained in a roll-on container equipped with such a metal ball is not clear, it is presumed that metal fine powders such as aluminum powder derived from the abrasive used when polishing the metal ball adhere during the manufacturing process of the metal ball, and this reacts with the fragrance components to form red precipitates. The material of the roll-on container is not particularly limited, and examples include polyethylene terephthalate, polypropylene, polyethylene, ABS resin, ethylene vinyl alcohol resin, polystyrene, glass, and the like.

[0035] Examples of the fragrance product of the present invention include eau de cologne, eau de toilette, eau de parfum, parfum, and the like.

[1] A fragrance product in which a fragrance composition containing component (A) a fragrance component and component (B) sodium dihydrogen phosphate is filled into a roll-on container equipped with a metal ball. [2] The fragrance product according to [1], wherein the fragrance composition further contains one or two selected from the group consisting of component (C) sodium hydrogen phosphate and sodium citrate. [3] The content of the component (A) is 1 to 35% by mass in the total amount of the fragrance composition, The fragrance product according to [1] or [2], wherein the content of the component (B) is 0.0005 to 0.2% by mass in the total amount of the fragrance composition.
