Description
United States Patent Melvin Arthur Goldberg, West Englewood, and William Roy Netzbandt, Dumont, NJ assignors to Lever Brothers Company, New York, N.Y., a corporation of Maine No Drawing. Filed May 1, 1962, Ser. No. 191,446 8 Claims. (Cl. 16790) This invention relates to an antiperspirant; and more particularly, it is concerned with an aerosol antiperspirant powder spray.
It is known to provide an antiperspirant in the form of a cream, a stick and a roll-on. However, these products have certain disadvantages since they may cause staining and dye bleeding on fabrics, may leave an undesirable feel on the skin, and may have excessive quantities of alcohol and soap therein. It is also known to dispense a liquid antiperspirant spray from a plastic squeeze bottle but the applied antiperspirant may run on the skin; this is also commercially undesirable.
In the past, an antiperspirant has been used in powdered form. However, there'has been considerable difiiculty in applying the powdered antiperspirant satisfactorily to the skin from the usual containers therefor. Although aerosol powder sprays have been in commercial existence, prior to this invention a suitable antiperspirant in the form of an aerosol powder spray could not be prepared.
It has now been discovered that an aerosol antiperspirant powder spray can be provided by forming a dispersion comprising an altuninum compound, an alcohol and a propellent. This dispersion is passed through a screen and the screened dispersion is subsequently packaged in an aerosol can under pressure. A spray of anti-perspirant is dispensed therefrom as desired and a substantially dry product is provided when it strikes the skin.
It is critical in the present invention to prepare a dispersion with an aluminum compound therein which is in fine particulate form and of a size sufficiently small to provide adequate coverage of the treated skin area. An aluminum compound, which has a particulate size to pass through a 200 mesh or finer screen, is suitable; however, finer sizes are preferred for better skin coverage and less likelihood of valve clogging. The preferred aluminum compounds pass through a 325 or finer mesh screen which avoids clogging in the currently available valves. Furthermore, an aluminum compound is defined herein as a compound which is not soluble in propellant and which has antiperspirant and astringent properties. Preferred compounds are aluminum chlorhydrate (aluminum chlorhydroxide complex) and aluminum sulfate. Aluminum chloride is also suitable for use in the practice of the invention provided that the dispersion is prepared and packed under strictly anhydrous conditions. It is also critical to use from about 4 to 10% of the aluminum compound, e.g., aluminum chlorhydrate, based upon the total weight of the aerosol antiperspirant powder spray. A larger amount is too dusty when sprayed and clogs the aerosol valve; and a smaller amount is relatively ineffective as an antiperspirant.
3,28%,581 Patented Nov. 29, 1956 ice Esters Within the purview of this invention, which are generally incorporated into the aforementioned dispersion, have the general structure:
wherein R is an aliphatic hydrocarbon group having 12 to 18 carbon atoms; R is selected from the group con sisting of an aliphatic hydrocarbon having 3 to 18 carbon atoms and an alkyleneoxy group having a terminal OH and having the formula (R"O) H wherein R" is an alkylene having at least 2 carbon atoms, n is an integer from 1 to 9, and the product of R" and n is from 3 to 18; and the sum of carbon atoms in R and R is from 15 to 34. Specific esters within this generic structure include isopropyl myristate-palmitate, propylene glycol monooleate and stearyl palmitate. The presence of an ester within critical limits facilitates dispersion of the powder and in particular makes it easier to re-disperse any powder that may settle on standing. It has been found that from 2 to 5% esters based upon total weight of spray is the operable range; more than 5%, e.g., 6%, provides a powder film which is too wet and less than 2%, e.g., 1%, provides little observable benefit.
Alcohol is also a critical component in the instant dispersion. Any known commercial alcohol, e.g., an admixture of 5 parts of methyl alcohol and 100 parts of 200 proof ethyl alcohol, is applicable. However, the range of alcohol required for the success of the present invention is 2 to 4 wt. percent based upon the total spray. The resultant spray is too wet if a higher alcohol c0n tent is employed and there is powder agglomeration if a lower alcohol content is used. Besides the specific commercial alcohol heretofore disclosed, the lower aliphatic alcohols are suitable provided the alcohol is soluble in propellent which includes the following: methanol, ethanol, n-propanol, isopropanol, propylene glycol, diethylene glycol and mixtures thereof.
The dispersion generally has a non-irritating germicide included therein within the range of 0.05 to 1.5 wt. percent based upon the total spray. The following germicides among others are suitable: 3,4,5 tribromosalicylanilide, hexachlorophene [2,2'-methylene-bis(3,4,6-trichlorophenol)], benzalkonium chloride (alkyl-dimethylbenzyl-ammonium chloride), 3,4,4'-trichlorocarbanilide and 2,2,3,4-tetrabromosalicylanilide.
It is critical in the instant invention to add at least one liquefied gaseous propellent to the dispersion prior to the screening operation. Dichlorodifluoromethane and 1,2-dichloro-l,1,2,2-tetrafluoroethane are suitable and either of them can be used as the only propellent in the system. Trichloromonofiuoromethane is also suitable but it must be employed in an admixture with another propellent, e.g., an admixture of 50% dicholrodifiuoromethane and 50% trichloromonofluoromethane. The trichloromonofluorometh-ane may also contain 0.3 nitromethane to inhibit acid formation. The aforementioned propellents, e.g., halogenated hydrocarbon propellents, comprise the balance of the aerosol antiperspirant powder spray, which is generally between 79 and based upon the total weight of the spray.
Although not essential for this invention, a perfume compound is usually included in the dispersion within 813 the range of .01 to .04%. The perfume can be any one which is known in the art. For example, the following perfumes are satisfactory: oil of lavender; oil of sandalwood; ylang-ylang; geranium; patchouli; and mixtures thereof. These perfumes can be employed alone or in blends with other materials.
After the dispersion with the aforementioned components has been formed, it is passed through a screen, such as a stainless steel screen with a mesh of at least 325. During this screening operation, the absorption of moisture should be avoided and agitation should be provided. The necessity for screening dry powder through a fine screen presents practical difficulties. Sufiicient dry powder can be screened for small batches if ample time is available for the screening operation, but it is impossible with the large scale production of the instant composition. We have discovered, however, that a dispersion can be screened readily on a large scale; this overcomes the necessity of screening the dry powder and makes this invention commercially feasible.
The screened dispersion is generally collected in a jacketed holding tank. However, a plain tank may be used with the screened dispersion being recirculated through a heat exchanger. The dispersion is thereby cooled to the desired temperature, e.g., 20 F. or less.
The cooled dispersion is subsequently incorporated into an aerosol can. Additional propellents, besides those included in the dispersion, may also be independently incorporated into the can. For example, if trichloromonofluoromethane is employed in the dispersion, dichlorodifluoromethane may be added to the aerosol can after the dspersion is packaged therein. A valve is then crimped on the aerosol can containing the dispersion and, optionally, the additional propellents. When the additional propellents are introduced through the valve after crimping, the dispersion need not be cooled below room temperature. As desired, the contents in the can are dispensed therefrom to provide an aerosol antiperspirant powder spray on the skin.
Thus in accordance with the present invention, it is now possible to form an antiperspirant which is an aerosol powder spray. Some of the components in the instant end product have been used in other forms of antiperspirant (U.S. Pat. Nos. 2,492,085 and 2,890,087). However, the success of this invention is dependent upon adhering to the critical limits of components therein and by following the required processing conditions. For example, it is essential that the dispersion be eflicient enough to prevent rapid settling of the solid particles.
The following examples are submitted to illustrate but not to limit this invention. Unless otherwise indicated, all parts and percentages in the specification are based upon weight.
Example 'I The following components were used to prepare an aerosol antiperspirant powder spray.

The TBS was dissolved in the alcohol while warming slightly. The Deltyl and perfume were added with subsequent cooling to below 74 F. Liquefied propellent 11 and chlorhydrol were consecutively incorporated into the system in conjunction with agitation. The resultant dispersion was passed through a 325 mesh stainless steel screen with continuous stirring into a jacketed holding tank which was also equipped with an agitator. The screened dispersion was cooled to 20 F. and loaded into aerosol cans. Liquefied propellent 12 was then added to the cans. Immediately thereafter, valves were crimped onto the cans.
It should be noted that it is important not to pick up moisture during the steps in this procedure. Furthermore, the dispersion should be kept well-stirred during the straining, holding and filling steps.
A suitable packaged end product was obtained in this example.
Example III An aerosol antiperspirant powder spray was formed from the components indicated herebelow following the same procedures described in Example II.

After screening and cooling as described in Example II, the dispersions were incorporated into aerosol containers by gravity flow. Cold propellent 12 was then incorporated into the containers and valves were crirnped thereon.
The containers were subjected to steam testing at 125 to 135 F., and then to water-bath testing at about 95 F. After being subjected to these tests, the containers were capped.
Satisfactory antiperspirant powder sprays were subsequently dispensed from aerosol containers with antiperspirants D, F, G and H. However, there was powder agglomeration in antiperspirant E which did not have alcohol included therein.
