Description

Warm feeling cosmetics

The present invention relates to a warm cosmetic that gives a warm feeling when applied to the skin. More specifically, the present invention relates to a warming cosmetic material having a high warming effect and excellent usability while containing a high amount of powder.

It is known that by warming the skin, blood circulation is promoted, metabolism is increased, and a blood color improving effect, a relaxation effect, a fatigue recovery effect, and the like are obtained. In anticipation of these effects, conventionally, exothermic substances have been blended into cosmetics. As exothermic substances to be blended in cosmetics, humectants such as polyhydric alcohols, zeolite, metal salts or metal oxides are widely used. All of these are hygroscopic and generate heat when in contact with moisture on the skin, thereby bringing warmth to the skin.

As a warming cosmetic using the heat of hydration of a polyhydric alcohol, for example, in Patent Document 1, a polyhydric alcohol is emulsified with a specific polyether-modified silicone to form an oil-in-polyhydric alcohol type. Proposed.
Patent Document 2 discloses a viscous cosmetic intended for wet skin, which contains a polyhydric alcohol and contains carrageenan in order to achieve both high viscosity and low spinnability. It has been proposed to contain xanthan gum and a specific hydroxy acid selected from citric acid, tartaric acid, lactic acid, malic acid, and fumaric acid in a specific mass ratio.
On the other hand, as a warming cosmetic using a zeolite, a metal salt, a metal oxide, or the like, Patent Document 3 contains a non-water thickener containing a hydrocarbon copolymer to improve storage stability. It has been proposed.

However, cosmetics containing any type of pyrogen are required to contain a large amount of powders or UV scattering agents that are usually used in cosmetics in order to improve usability and UV protection effects. . Examples of such cosmetics include makeup bases, foundations, sun care products, and the like.
