[0004] The strength of the cooling sensation caused by a cooling cosmetic is controlled by adjusting the content of the cooling ingredient in the cosmetic. However, when the content of the cooling ingredient in the cosmetic is increased to enhance the cooling sensation, some types of cooling ingredients may cause discomfort such as pain or a burning sensation when the cosmetic is applied to the skin. For these reasons, there is a demand for the development of a cooling cosmetic with an enhanced cooling sensation without increasing the content of the cooling ingredient, and a method for enhancing the cooling sensation.

[0005] An object of the present invention is to provide a refreshing cosmetic composition having an enhanced refreshing sensation, and a method for enhancing the refreshing sensation without increasing the content of a refreshing component. [Means for solving the problem]
