Embodiment

[0090] With ultrasonic sprayer, ink-jet sprayer and electrostatic atomization sprayer, the spraying agent of 10% aqueous solution is that the mass percent of atomized spray GABA is 10% respectively, utilizes QCM (quartz crystal microbalance) cascade impactor and DMA (Differential fluidity analyzer) The particle size distribution of the solution at this time was measured. Measurements were made at a distance of 2 to 3 cm from the spray port.

[0091] Fig. 1 is a graph showing the relationship between the particle size of the solution and the percentage of the solution when the solution is nebulized by an ultrasonic nebulizer. Fig. 2 is a graph showing the relationship between the particle size of the solution and the percentage of the solution when the solution is sprayed by an inkjet spray device. Fig. 3 is a graph showing the relationship between the particle size of the solution and the percentage of the solution when the solution is sprayed by an electrostatic atomization ...

Abstract

To provide an atmosphere alteration method which enables GABA to be taken into a body by a method completely different from a conventional method.A solution prepared by dissolving [gamma]-aminobutyric acid as a solute in a solvent is sprayed in a space. Preferably, the solution is sprayed so as to form particles with a particle diameter of 10 [mu]m or smaller.

Description

technical field [0001] The present invention relates to a method of changing the atmosphere of internal body space, indoor space, etc., and a spray and a spray device used in the method of changing the atmosphere. Background technique [0002] It has been confirmed that γ-aminobutyric acid (γ-aminobutyric acid: hereinafter referred to as “GABA”) has various pharmacological actions. Specifically, the pharmacological effects include: the blood pressure adjustment effect of normalizing blood pressure, the effect of inhibiting the increase of cholesterol and neutral fat in the blood, the effect of promoting the functions of the kidneys, liver, and pancreas, and the effect of inhibiting the rise of blood sugar levels, making the blood healthy. Influx into the brain to promote brain cell metabolism, obesity prevention effect, alcohol metabolism promotion effect, deodorization effect of body odor and bad breath, relief effect of emotion disorder and anxiety disorder, improvement ef...
