ABSTRACT OF THE DISCLOSURE An 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 normal butane, isobutane, propane, and mixtures thereof, and from about 0.5-3.3% by weight carbon dioxide. A substantially non- flammable antiperspirant composition comprising a propellant intermediate 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% by weight of propellant intermediate of a hydrocarbon propellant selected from the group consisting of normal butane, isobutane, propane, and mixtures thereof, from about 0.5-3.3% by weight of propellant intermediate carbon dioxide, and an antiperspir- ant intermediate comprising from about 20-60% by weight of an antiperspirant 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, baking soda and mixtures thereof, and from 1-10% by weight of an antiperspirant intermediate of a bulking agent wherein the ratio of propellant intermediate to antiperspirant intermediate is from 33:1 to 2:1.
