Description

TECHNICAL FIELD The present invention relates to a warm-sensitive oily cosmetic.

BACKGROUND ART Conventionally, in the technical fields of massage cosmetics and cleansing cosmetics, many attempts to impart a warming effect have been investigated. Many of such cosmetics utilize the heat of hydration of polyhydric alcohols from the viewpoint of safety to the skin and the viewpoint of mild heat generation.

Specifically, a gel-like warming massage agent containing glycerin or diglycerin, an anionic polymer compound, and water (see, for example, Patent Document 1), a specific polyhydric alcohol, a scrubbing agent, and a water-soluble polymer compound. (see, for example, Patent Document 2), a cleansing agent containing glycerin, a specific crosslinked polymer, a specific thickener, and a specific nonionic surfactant (see, for example, Patent Document 3) etc., have been proposed.

However, with the heat of hydration of polyhydric alcohols, there is a problem that the expression of warmth is moderate, the duration of the sensation of warmth is short, and it is difficult to obtain the desired sensation of warmth. Furthermore, although polyhydric alcohols can be easily blended in non-aqueous cosmetics containing no water, in oil-based cosmetics in which the majority of the cosmetics are oils, even if they are blended, they do not produce a warm feeling. is difficult.
