AEROSOL PROPELLANT FROM CHLORINATED ALKANE, ALKANE AND CARBON DIOXIDE FOR ANTIPERSPIRANT

摘要

ABSTRACT OF THE DISCLOSUREAn improved, substantially non-flammable, non-fluoro-carbon containing propellant system comprising from about 65-85% by weight of a compound selected from 1,1,1-trichloro-ethane, dichloromethane, and mixture thereof, from about 14-32% by weight of a hydrocarbon propellant selected from normalbutane, isobutane, propane, and mixtures thereof, and fromabout 0.5-3.3% by weight carbon dioxide. A substantially non-flammable antiperspirant composition comprising a propellantintermediate comprising 65-85% by weight of propellant inter-mediate of a compund selected from 1,1,1-trichloroethane, di-chloromethane, and mixtures thereof, from about 14-32% byweight of propellant intermediate of a hydrocarbon propellantselected from the group consisting of normal butane, isobutane,propane, and mixtures thereof, from about 0.5-3.3% by weightof propellant intermediate carbon dioxide, and an antiperspir-ant intermediate comprising from about 20-60% by weight of anantiperspirant intermediate astringent salt, from about 20-79%by weight of an antiperspirant intermediate of an emollient,from about 0-10% by weight of a powder talc, starch, bakingsoda and mixtures thereof, and from 1-10% by weight ofan antiperspirant intermediate of a bulking agent wherein theratio of propellant intermediate to antiperspirant intermediateis from 33:1 to 2:1.
