Description

Technical Field

[0001] The present invention relates to a stick-shaped antiperspirant composition.

Background Art

[0002] Many conventional antiperspirant compositions leave a sticky feeling after application, so there is a demand for an antiperspirant composition that is excellent in the smooth feeling of the skin after application. In addition, there is a demand for a stick-shaped antiperspirant composition that can be easily molded and is excellent in various performances such as ease of application and non-sweating when applying the antiperspirant composition.

[0003] For example, for the purpose of improving the antiperspirant effect, stickiness after application, and resistance to breakage of the agent, a solid antiperspirant composition containing a solid oil that is solid at 25°C, a specific surfactant, and water has been proposed (for example, see Patent Document 1). However, in conventional solid antiperspirant compositions including the above Patent Document 1, the smooth feeling of the skin after application, as well as the ease of application of the agent and non-sweating, have not been studied, and there is room for further improvement.

[0004] Therefore, it is desired to develop a stick-shaped antiperspirant composition that is excellent in ease of application of the agent, non-sweating, and moldability, and is also excellent in the smooth feeling of the skin after application.

In this specification, the "stick-shaped antiperspirant composition" may sometimes simply be referred to as the "antiperspirant composition" or "agent". "(A) Alum" may sometimes be referred to as "(A)" or "(A) component". "(B) Solid oil that is solid at 25°C" may sometimes be referred to as "(B)" or "(B) component". "(C) Liquid oil that is liquid at 25°C" may sometimes be referred to as "(C)" or "(C) component". "(D) Liquid oil that is liquid at 25°C and represented by formula (1)" may sometimes be referred to as "(D)" or "(D) component".

[0012] "Oil sweating" as used in this specification refers to the occurrence of liquid oil (oil droplets) on the surface of the agent due to the oil separation phenomenon over time.

[0013] <(A) Alum> The said (A) component imparts a good antiperspirant effect to the antiperspirant composition.

[0014] There are no particular restrictions on the said (A) component, and it can be appropriately selected according to the purpose. However, from the perspective of good moldability into a stick shape, dried potassium aluminum sulfate, dried ammonium aluminum sulfate, potassium aluminum sulfate, and ammonium aluminum sulfate are preferred, and dried potassium aluminum sulfate and dried ammonium aluminum sulfate are more preferred. Note that dried potassium aluminum sulfate is obtained by heating and dehydrating potassium aluminum sulfate, and dried ammonium aluminum sulfate is obtained by heating and dehydrating ammonium aluminum sulfate. These may be used alone or in combination of two or more.

[0015] For the said (A) component, appropriately synthesized products may be used, or commercially available products may be used. Examples of commercially available products of the said (A) component include, by trade name, Tai Ace K150 (dried potassium aluminum sulfate), Tai Ace K20 (dried potassium aluminum sulfate), roasted ammonium alum (dried ammonium aluminum sulfate) (all manufactured by Daimyo Chemical Industry Co., Ltd.), etc.

However, from the viewpoints of good moldability into a stick shape and good spreadability of the agent, it is preferably 10% by mass or more and 40% by mass or less, more preferably 20% by mass or more and 35% by mass or less, based on the total amount of the antiperspirant composition. When the content of the component (A) is 10% by mass or more based on the total amount of the antiperspirant composition, the moldability into a stick shape becomes good. When the content of the component (A) is 40% by mass or less based on the total amount of the antiperspirant composition, the hardness of the agent becomes good and the spreadability of the agent becomes good.

[0017] <Solid oil that is solid at 25°C (B)> The component (B) imparts good moldability into a stick shape to the antiperspirant composition.
