solution to the problem of corrosion in using a preventive hydrogen propellant.

rer for electrolytic type corrosion to the propellant system used makes about 24 use. Generally up to 40% of the aerosol composition has been found to be off. Little both Organophosphites as well as amounts of propellant that prevent corrosion cause difficulties those based on acetylene are effective. As particularly useful when spraying, especially when a pack preferred anti-corrosive agent has organo- is partially emptied. Larger amount of propellant Phosphite proved that in an amount of about make the composition flammable, even can-0.1 ° / o is used. they cause gelation problems. A special one though the aluminum chlorohydroxide-propylene- the preferred aerosol composition according to glycol complex has a bacteriostatic activity to 15 of the invention contains about 30 weight percent leavening seems, very small amounts of the agent system, based on the composition, can also be used bacteriostatic agents are added. The main ingredient of the present invention according to use In a preferred embodiment the propellant system is a hydrocarbon According to the invention, the composition does not contain a propellant. Propane, η-butane and isobutane are ge-hexachlorophene. It has been found that 20 can be useful hydrocarbon propellants. For the inven-hexachlorophene Intolerance problems on the use according to the invention will usually occur isobutane, as is preferred in the formation of an unpleasant pink. The remaining part of the propellant system brown color is expressed when in forms a fluorocarbon propellant. As beder Composition traces of iron are dissolved. preferred fluorocarbon blowing agent Generally, all of these other 25 dichlorodifluoromethane, propellant 12, are used. That further additives do not exceed about 5 ° / o. Ge. ratio used in the propellant system habitually the compositions contain 2.5 to from hydrocarbon propellants to 4.5 fluorocarbons ° / o of these additives. Hydrogen propellant is 2: 1. Preferably Examples of suitable humectants are, according to the invention, a deodorizing aerosol hexadecyl alcohol, Isopropyl myristate, isopropylpal- 30 composition uses which is about 20% isobutane mitate, di-isopropyl adipate and cetyl stearyl adipate, where and contains about 10% propellant 12, in the case of hexadecyl alcohol in a concentration of The antiperspirant aerosol according to the invention, about 2% is preferred. Smoothing agents are silicones, so they are supplied in a package known per se z. B. at room temperature as a liquid that fills a metal, glass or synthetic resin container can lie. One possible anti-yellowing level is a 35 may be. For the aerosol according to the invention can mixture from about 60% mono- and about 40% diene, relatively inexpensive metal containers with an ausoleylenea- (polyoxyätyl) -ätlrylorthophosphat, clothing is used, while for some skin irritation also reduces the acidity of the complicated and expensive containers caused by the familiar products the deodorant composition are undesirable. A metal container folded on the side could be caused. 40 with a liner is for the inventive

The active ingredient that is quite suitable in the product according to the invention.

According to Aerosol Deodorant Compositions The invention is applied in the light of the following is known. Explained in more detail as an active component: an organic aluminum chlorohydroxide com-

a particular feature of the present invention. The inventive, antiperspirant aerospace

Thanks to its composition, sol has the further advantage that it dries relatively quickly without being sticky to become when it is placed on the skin. In addition, the aerosol becomes a relatively inexpensive one Propellant system is used and relatively inexpensive metal containers with a seam can be used will.

The deodorizing aerosol mixture produced according to the example was used for the Spraying the axisi cave used. They have been found to be extremely effective when used in every way judged as a deodorant or antiperspirant. During storage (at 21, 38 and 54 ° C) the product proved to be stable for more than 2 years. The product was not flammable.

The deodorizing aerosol products according to the invention differ from the known products different components. For example, the products show a very high degree of deodorizing Effectiveness, they don't need to be shaken before use, they have one The shelf life is over 1 year and there are no valve clogging problems. In addition, the compositions used in the products dry relatively quickly without them become sticky when placed on the skin. In addition, the product becomes a relative Inexpensive propellant system used, and relatively inexpensive metal containers with a Seam can be used.
