Definitions

• Aerosol anti-perspirant compositions in which the astringent material, e.g. aluminum chlorhydroxide, is dispensed as a solid suspended in an anhydrous hydrophobic liquid vehicle such as mineral oil, isopropyl myristate or isopropyl palmitate have been widely marketed. Although such compositions are effective in reducing perspiration they have a tendency to impart stains to clothing which (stains) remain subsequent to laundering.
• the present invention is concerned with providing anti-perspirant compositions of this type which have substantially reduced tendency to stain clothing.
• R is a hydrogen atom or a 2 to 3 carbon acyl group, i.e. an acetyl or a propionyl group and each R is the same or different than the other R s and is an alkyl radical comprising less than 4 carbon atoms.
• each R is an ethyl radical.
• triethylcitrate and acetyl triethylcitrate are examples of compounds within the above formula, mention may be made of triethylcitrate and acetyl triethylcitrate. Especially good results have been obtained with triethylcitrate which has been found to be particularly non-toxic, non-irritating and non-corrosive, has good stability in the compositions and in certain instances actually enhances the fragrance of the perfumes used therein.
• R is a hydrogen
• the hydroxy group may be alkoxylated by a 1 to 3 carbon alkyl group or the alkyl radicals (R may be further substituted by hydroxy or 1 to 2 carbon alkoxy groups provided that the esters remain miscible with the propellant and the number of carbon atoms is commensurate with that set forth above.
• the astringent may be selected from any of the materials of this nature which are available, e.g. aluminum sulfate, aluminum chloride, aluminum chlorhydroxides such as Al(OH) Cl and Al OH Cl aluminum sulfocarbolate, zinc chloride, zinc sulfocarbolate, zinc sulfate, zirconium oxychloride, sodium zirconium lactate, sodium zirconium glycolate, zirconyl hydroxy chloride, zirconium sulfate, physical mixtures of the above, and mixed compounds and complexes comprising 2 or more of the 3,833,721 Patented Sept. 3, 1974 above cations such as a mixed aluminum zirconium chlorhydroxide complex.
• aluminum sulfate aluminum chloride
• aluminum chlorhydroxides such as Al(OH) Cl and Al OH Cl
• aluminum sulfocarbolate zinc chloride, zinc sulfocarbolate, zinc sulfate, zirconium oxych
• the preferred astringents for use in the composition of this invention are the aluminum chlorhydroxides.
• the amount of astringent employed may be varied but in most compositions it will be present in amounts ranging between about 0.5% to about 10% by weight of the total composition including the propellant. In preferred compositions, it will be present in amounts ranging between about 1 to about 7.5%.
• the astringent should be finely ground in order to prevent the valve from clogging. Usually if the particle size is less than 100 microns and preferably less than 60 microns, clogging will be held to a minimum.
• the ester is present in amounts such that in combination with the propellant it will be the continuous phase of the dispersion or suspension. As can be appreciated, this amount will vary depending upon the amount of astringent employed. In most instances, the ester will comprise from about 0.5 to about 50% by weight of the total composition including the propellant. In preferred compositions, the ester is present in amounts ranging between about 0.5 to about 15%.
• any of the materials which have been employed as propellants in aerosol compositions may be used in the compositions of the present invention; provided of course that they are miscible with the liquid vehicle.
• the propellant will generally be present in amounts which will be sufiicient to dispense all of the composition at a moderate velocity. In most instances the compositions will have vapor pressures ranging between 15 and 85 p.s.i.g. and preferably between 20 and 40-. Generally the propellant will be present in amounts varying between 50 to 98% by weight of the total composition and preferably between to 98%.
• compositions of the present invention will further include a suspending, dispersing or flocculating agent to prevent the astringent from agglomerating or settling.
• a suspending, dispersing or flocculating agent to prevent the astringent from agglomerating or settling.
• a suspending, dispersing or flocculating agent to prevent the astringent from agglomerating or settling.
• such agents mention may be made of clays, such as bentonite, modified clays, e.g. the reaction product of bentonite and a surface active quaternary salt, silicas such as colloidal silicon dioxide, silicates, polymeric suspending agents such as cellulose and derivates thereof and surfactants such as high molecular weight amides, e.g. lauryl monoethanolamide.
• the compositions may further include other ingredients such as perfumes, emollients, talc, starches, anti-bacterials, etc.
• compositions of the present invention in reducing stain was demonstrated by using the esters disclosed herein on a weight basis in place of isopropyl palmitate in a standard formula and measuring the extent of staining it caused as compared with the composition containing isopropyl palmitate.
• the standard formula was as follows:
• the triethyl citrate has substantially lower stain indiccs than the isopropyl palmitate.
• Table II summarizes the results of a test in which acetyl triethylcitrate was run against isopropyl palmitate.
• the triethyl citrate formulation was tested along with an isopropyl palmitate control composition on twenty different synthetic and natural fibers for 1 cycle of the above mentioned stain test. On only one type material (diacetate) was the citrate formulation found to cause more stain than the control.
• An aerosol astringent composition having improved antistain properties, said composition comprising 0.5% to 10% by weight of an astringent material selected from the group consisting of aluminum sulfate, aluminum chloride, aluminum chlorohydroxide, aluminum sulfocarbolate, zinc chloride, zinc sulfocarbolate, zinc sulfate, zirconium oxychloride, sodium zirconium lactate, sodium zirconium glycolate, zirconyl hydroxy chloride, zirconium sulfate and aluminum zirconium chlorohydroxide complex, 50 to 98% by weight of a propellant selected from the group consisting of dichlorodifluoromethane, trichloromonofluoromethane, trichlorotrifiuorethane, tetraflurodichloroethane, butane, propane, isobutane and mixtures and blends thereof and 0.5 to 50% by weight of a vehicle, said astringent material being insoluble
• R is a hydrogen atom or a 2 to 3 carbon acyl group and each R may be the same or different than the other Rfs and is an alkyl radical comprising less than 4 carbon atoms, said percentages are based on weight of the total composition.
• composition as defined in claim 1 wherein said astringent material is aluminum chlorhydroxide.
• composition as defined in claim 1 wherein said 5 OTHER REFERENCES vehicle is acety1triethy1citrate de Navarre International Encyclopedia of Cosmetic 9.
