Abstract:
An anhydrous, liquid, antimicrobial composition, comprising:(a) from about 30 to about 50 percent by weight of a quaternary compound selected from the group consisting of 1-(benzyl)-3,5,7-triaza-1-azoniaadamantane chloride, 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride as the cis-isomer or a mixture of the cis-isomer and the trans-isomer thereof, 1-(&agr;-(2-xylyl))-3,5,7-triaza-1-azoniaadamantane chloride and methyl 1-(3,5,7-triaza-1-azoniaadamantane chloride) acetate; (b) from about 25 to about 70 percent by weight of an anhydrous carrier liquid which does not reduce the amount of antimicrobial activity of the quaternary compound or cause the Gardner color of the composition to be more than 3 during storage under room temperature conditions for time periods of up to six months. the anhydrous carrier liquid being selected from the group consisting of PPG-5-laureth-5, isosteareth-10, PEG-20 corn glyceride,methyl gluceth-20, laureth-9, oleth-3, nonylphenoxypoly(ethyleneoxy)ethanol, PEG 400 monolaurate, PEG 1200 castor oil, PEG 400 dilaurate, C11-C15 secondary alcohol ethoxylates, caprylic/capric triglyceride, Polyglycol, polysorbate-20, tripropylene glycol methyl ether, mineral oil, lanolin oil, safflower oil, propylene carbonate, toluene and acetone; and (c) from about 0.1 to about 10 percent by weight of a thixotropic material which does not cause a reduction of antimicrobial activity of the quaternary compound and retards substantial settling of the composition during storage under room temperature conditions for time periods of up to six months.
