PURPOSE: To obtain an aerosol compsn. without causing excessive coolness, pain and stickiness when it is injected and to improve dispersibility and usability of a powder by mixing a specified aerosol propellant and a solvent. n CONSTITUTION: An aerosol propellant with a vapor pressure (gauge pressure) at 20°C of 0.1-3.0kg/cm 2 , obtd. by mixing 15-65wt.% one or more aerosol propellants selected from propane, n-butane and isobutane and 35-85wt.% one or more solvents selected from n-pentane, isopentane and n-hexane, is compounded with a lipophilic powder (e.g. PE) contg. 0.1-30wt.% lipophilically treated inorg. powder (e.g. cation-modified bentonite). n COPYRIGHT: (C)1991,JPO&Japio |
