Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic suitable for a foam cosmetic having a warm feeling.

  One of the important factors when applying makeup such as a pack or massage is to feel warmth. This is because the effect expected in such a makeup act is a blood circulation promoting action, and by feeling a sense of warmth, the actual feeling of such an effect is realized, and as a result, the makeup act itself is greatly satisfied. This is because a feeling of warmth and a feeling of moderate warmth embody the comfort of use, and this pleasant sensation prepares the environment of a personal ecosystem and exerts favorable effects on health. Examples of methods for embodying such warming cosmetics include methods using heat generated by oxidation reaction of metal oxide with water and neutralization reaction with acid, glycerin, dipropylene glycol, liquid polyethylene glycol, etc. There is a method that utilizes the heat of hydration that occurs when solvates with water. Among these, the former is a two-component system, and there is a drawback that the heat generation cannot be controlled unless it takes the form of mixing at the time of use. In the latter, a single-agent system can be formulated, There was a drawback that the calorific value itself was small. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4) That is, in such a one-component cosmetic, an appropriate temperature of about 50 ° C. usually lasts only about 3 to 5 minutes. .

  On the other hand, it is already known that foam-shaped cosmetics have a blocking effect, a heat insulating effect, and the like and are suitable for pack cosmetics. In foam-like cosmetics, it is also known that acylated polyglycerin such as decaglycerin monolaurate and diglycerin monolaurate has excellent foaming properties. (For example, see Patent Document 5, Patent Document 6, Patent Document 7, and Patent Document 8) However, there is no known formulation technology for making a non-aqueous emulsion into a foam. There is no known warm foam cosmetic using heat of hydration.

  Also, foam cosmetics containing 1) acylated polyglycerin, 2) 15 to 80% by mass of polyhydric alcohol, and 3) 15 to 80% by mass of an oily component that is liquid at 25 ° C. and 1 atm are not known. It is not known at all that the cosmetic material having such a configuration exhibits an excellent thermal effect during use.
