Definitions
- This invention relates to chemical compositions under pressure which contain propellants for discharging them from a container through a dispensing valve into the atmosphere.
- carbon dioxide has been used in some cases in combination with Freon as a propellant assistant.
- This in accordance with the prior art, is done by either charging the container with carbon dioxide gas directly or by the insertion of pellets of solid carbon dioxide (Dry Ice) in the container just before the containers with the usual dispensing valve are hermetically sealed.
- the solid carbon dioxide soon sublimes into its gaseous form, a portion of which may become dissolved in the liquid phase of the composition.
- One of the objects of this invention is the provision of a novel method of providing carbon dioxide gas as a propellant assistant for Freon in compositions of the type mentioned.
- a further object of the invention is the provision of a composition of matter adapted to be stored under pressure in a hermetically sealed container.
- a still further object of the invention is the reduction in the cost of providing compositions of matter containing propellant gases.
- a further object of the invention is to provide aerosol compositions in which water is substituted for a substantial portion of organic solvents previously employed.
- the cost of manufacturing the composition is accordingly substantially reduced.
- the nature of the compositions provided by this invention are such that water may be employed as a component along with components such as 2,964,165 Patented Dec. 13, 1960 ice 'propellant assistant aids, in some cases, in making it feasible to reduce the amount of fluorinated hydrocarbon (Freon, lsotron, Genetron) which is also employed as a propellant, and thereby in effecting additional savings in the cost of manufacturing the compositions.
- a further purpose of the invention is to provide noncorrosive aerosol compositions employing a substantial proportion of water in which carbon dioxide is employed as a propellant assistant, and which are capable of maintaining the spraying pressure throughout the shelf-life of the composition which at a minimum is from 15 to 20 months.
- a further object of the invention is to provide aerosol compositions which comprise an aqueous phase and an organic liquid phase which have substantially similar densities, so that emulsification of the entire composition can be readily attained.
- a further object is to provide such compositions which are noncorrosive with respect to tin lined metal containers and in which substantial amounts of carbon dioxide may be dissolved to serve as a propellant assistant.
- a further important object of the present invention is to provide aerosol compositions which contain a substantial amount of water and methylene chloride, Freon-l1 or other organic components which are known on hydrolysis to produce corrosive products and which nevertheless are noncorrosive with respect to tin lined metal containers.
- propellant as used herein without any further designation is to be construed as meaning one or more of the low boiling point fiuorochlorohydrocarbons which are commonly employed as aerosol propellants.
- propellant also includes mixtures of these hydrocarbons as well as other commonly known aerosol propellants such as methyl chlorlde, etc. It will also be understood that the propellant will cover mixtures of the compounds mentioned above with vapor pressure modifying components such as methylene chloride, methyl chloroform and similar blends of compounds which are known in the art.
- propellant assistant is meant to designate gases such as carbon dioxide and nitrous oxide which are not condensible at pressures and temperatures ordinarily encountered in aerosol products.
- fiuorochlorohydrocarbons such as contemplated by the above definition of propellants are the compounds sold generally under the trade designations of Freons, Genetrons and Isotrons.
- Most commercial aerosol products employ propellants which at room temperature have a vapor pressure of 40 to pounds 7 per square inch and the present invention is accordingly concerned in large degree with propellants exhibiting vapor pressures in this range.
- a portion of the Freon is substituted by an unreacted used, may thus be furnished from an external source as a gas or as a solid, or may be formed in situ, as described above.
- the presence of the substantial amount of water in the composition enables a tiseful amount of carbon mixture of water, sodium and/ or potassiumbicarbonate v 5 dioxide to be dissolved and therefore permits replaceand an acidjwhich canreact withrthe bicarbonate generate carbon dioxide;
- the preferred procedure is gto 7 place in. an open container, equipped with the usu discharge or dispensing valve, a quantity of the. material ment of the more expensive fluorohydrocarbon propellant with carbon dioxide.
- nitrous oxide employed as a propellant assistant in lieu of to be dispensed therefrom and also a given quantity of 10 carbondi xide', solubility'does f'notseemito water together with the bicarbonate and acidin dry form
- the preferred procedure in some eases todissolve. the bicarbonate in a portion of the water which'is to beused in making p s m sit qn and t n ad the acid be as great. Nevertheless, the use of nitjrous oxide asa propellant. assistantjnay be desirable insome instances.
- the invention is ap pli cable to compositions .wherein nitrous oxide and/or carbon dioxide are used in tablet form, for example in the case .of citric ,acid. as t p pel t, n 110 fl qr hyg dqa (FIEOIIQ In other instances,;both the citric acid and the bicarbonatef have been predissolvedinseparate" portionsofthe water which is to be employed. The-container is promptly.
- Genetron, isotron is employed.
- it is applicable to edible compositions of the kind which employ a propellant comprising 85% nitrous oxide and 15% sealed after the above-named components are addedfand carbon dioxide.
- succinic, and adlpic maybe used in specific, instancesl
- the invention is useful in all the various t ypesoffproi pellant compositions now in commerciallfuse such as insecticides, perfurnants, paints eleaners plasticsgartificial snow. producing compositions, deodoran'ts," hair 'f: ;-r"
- composition is. prepaied by placingin the contairier to. be .used, equipped with the usual dispensing ve t p op l n yco t e l y o s p c y J 'alcohol, methylene chloride and waterl.
- ve t p op l n yco t e l y o s p c y J 'alcohol
- methylene chloride methylene chloride
- waterl methylene chloride
- An artificial snow producing composition in accordance with the present invention has the following composition, by weight:
- the pressure was increased to 65 pounds per square inch at 70 F. and it was possible to completely dispense the contents of the container.
- Example 3 An insecticidal composition in accordance with this invention which is particularly effective against flies comprises the following ingredients in the proportions indicated by weight:
- composition was prepared similarly to the previous one mentioned in which all but the last three ingredients listed were first placed in the dispensing container, then the potassium bicarbonate and citric acid in dry form. The container was then promptly sealed and the Freon injected into the container through the dispensing valve under hydraulic pressure.
- the containers employed were conventional six-ounce cans having a tin lining.
- the samples were opened after more than a years storage, and no corrosion had occurred; the formation of a gray film on the interior sur-- face of the can was observed in all samples.
- the pH value of the described compositions is in the area where attack on the tin lining of the cans would be minimized, and in addition to this, the compositions have the characteristic of very early forming a gray film on the tin-plated interior of the cans which does not change in character over the course of long storage.
- the invention is particularly applicable, especially with respect to'the fea-' ture which permits employing useful amounts of carbon dioxide as a propellant or propellant assistant.
- an acid and carbonate are employed to produce. the prop pellant assistant in situ; as well as provide the, anticorrosion' action, the. combined amount of acid and carbonate'rnay range from .5 "to 2.0%, depending upon the pressure desired. The larger amounts may be used where high-pressures are desired, for example in some commercial applications where large, strong containers are employed.
- the initial pH value may be adjusted in the range 01Ev 3.5 to 4.5,, but preferably'atv thehigher: figurein such cases.
- emulsifiers are applicable to ⁇ - the compositions v described herein. .Forj example',..the emulsification ofl water and organic: liquid: phases, may be greatly facilitated by employing emulsifiers sold under-the trade name Pluronic L-64, Tween-20, Span-20, as well as others which,
