Problems solved by technology

[0013] In addition, the inventors of the present invention have conducted research on the use of warm-sensing compositions as aerosol preparations. As a result, there is the following problem: Although aerosol preparations have It is used in the discharge mechanism of the composition sprayed with a propellant, but in the aerosol preparation using zeolite, the zeolite as a powder will clog the discharge mechanism (the second problem)

preparation example Construction

[0052] The method for preparing the warming composition is not particularly limited, and it can be prepared according to a conventional method. That is, polyhydric alcohol, a thickener, etc. are put into a dissolution tank in the ratio described above, and it heats and dissolves uniformly, and forms a gel. Next, granular bodies containing zeolite nanoparticles as a main component were introduced and mixed and dispersed to homogenize the component phases to prepare a composition.

[0053] Generally, a composition filled into an aerosol preparation preferably has a moderate viscosity in order to obtain a desired discharge amount and to maintain good dispersibility in a powder-containing composition for a long period of time. The inventors of the present invention have found a new problem that it is very difficult to thicken polyethylene glycol preferably used in the present invention. As a result of intensive studies to solve this problem, it was found that the thickener that s...

Abstract

The present invention addresses the problem of providing: a warming composition that has favorable dispersion stability after long-term storage, has high warming impact, and better preserves the distinctive sensation imparted by zeolite; and an aerosol formulation that includes the warming composition. According to the present invention, the heat generated by a hydration reaction between water andthe zeolite of a warming composition that contains zeolite nanoparticles that have an average particle size of no more than 500 nm quickly raises the temperature of the composition.

Description

technical field [0001] The invention relates to a temperature-sensitive composition containing exothermic substances and an aerosol preparation containing the temperature-sensitive composition. Background technique [0002] If the composition applied to the skin of the human body has exothermic properties, various effects called thermal effects can be expected, such as the following effects: the pleasure of application due to the sense of warmth; the promotion of blood circulation Activation of the skin (recovery from fatigue, activation of metabolism, improvement of appearance, etc.); expansion of pores, improvement of removal of epidermal dirt due to heat; and the like. [0003] As a heat-generating preparation that brings such effects, a composition has been developed, which applies a composition containing zeolite and polyhydric alcohol to the skin, and generates heat by reacting with moisture in the skin (for example, see Patent Document 1 ~Patent Document 3). These p...
