Abstract

A stable, anhydrous aerosol foam capable of suspending up to 50% by weight of dispersed anhydrous particulate solids capable of absorbing water exothermically is prepared from such solids and a foamable liquid oil, a foaming agent and a propellant.

Description

EXOTHERMIC STABLE FOAM COMPOSITIONS Description of the Invention

This application is a continuation-in-part of Patent Application Serial No. 713,293, filed March 18, 1985.

The use of anhydrous particulate absorbant materials capable of sorbing water exothermically in autoheating cosmetic and similar compositions is well known. Menkart, et al., in Canadian Patent No. 748,049, disclose liquids, creams, gels and pastes which utilize materials such as silica gel, activated alumina, and alkali metal alumino silicate molecular sieves (Zeolites) in non-aqueous vehicles which warm automatically on contact with moisture in or on the skin. Analgesic preparations containing Zeolite in an anhydrous liquid are disclosed in U.S. Patent No. 4,379,143. Cosmetic vehicles comprising a carboxy vinyl polymer and Zeolites are disclosed in U.S. Patent No. 4,362.715. A toothpaste containing Zeolite is disclosed in U.S. Patent No. 4,349,533.

Despite the foregoing disclosures, no products based on such formulations have been successfully marketed because such formulations are cosmetically inelegant, i.e., they are very oily, greasy and pasty in consistency; spread poorly on the skin, and leave the skin with a greasy feel and appearance. These undesirable characteristics result from the fact that water or hydroxylated solvents such as alcohols or glycols must normally be omitted in order to preserve the exothermic reactivity of the particulate absorbants.

Copending U.S. Patent Application Serial No. 778,026 filed on September 20, 1985 describes and claims novel anhydrous aerosol foams which are capable of suspending up to 50% by weight of a dispersed solid without causing malfunction of an aerosol valve. The novel properties of these aerosol foams make them suitable for use as delivery systems for a wide range of therapeutic agents and provide an alternative to tablets or capsules, which are difficult to swallow or bad tasting liquid medications.

It has now been unexpectedly discovered that the aerosol foam delivery system described and claimed in copending Application Serial No. 778,026 is capable of functioning to provide a cosmetically elegant delivery system for formulations containing particulate absorbant materials capable of sorbing water exothermically alone or in combination with other therapeutic or cosmetic ingredients. Specifically, it has now been found that a stable, anhydrous aerosol foam or whip capable of suspending up to 50% by weight of a dispersed solid can be prepared from a foamable anhydrous liquid oil; a foaming agent; and controlled amounts of a propellant which are sufficient to produce a stable foam rather than a spray. The foam, as delivered from an aerosol canister, has the consistency of whipped cream, is stable for extended periods and is .hostile to the growth of micro-organisms.

While not wishing to be limited to any particular theory, it is presently believed that the expansion of the formulations caused by the presence of a propellant causes the product to spread in the form of a thin film on the skin, thereby giving a soft, silky, and cosmetically elegant feel. The observed effect is analogous to a comparison between whipped cream and butter. While both of these products are produced from cream, butter is a dense, greasy water in oil emulsion, whereas whipped cream is a light air in oil emulsion in which the oil is extended over a much greater volume, thereby masking its greasy properties to a substantial extent. In the present invention, by foaming the oils with a propellant to produce a low' density aerated whip or mousse, the greasy property of the oil in the formulation is eliminated. The invention makes it possible to achieve the foregoing results without valve clogging due to a novel combination of ingredients that produces a high viscosity formulation capable of keeping the small solids particles dispersed and of lubricating the aerosol valve.

The foamable, anhydrous liquid oils utilized in the present invention are varied and of no great critical significance. Typical among the organic oils useful for the present invention are those such as soybean oil, partially hydrogenated soybean oil, linseed oil, corn oil, peanut oil, sunflower oil, cottonseed oil, olive oil. castor oil, liquid petrolatum, oleic acid, lauric acid, and mono- and diglyceride oils. As indicated above, the basic criterion for a liquid oil utilizable in the present invention is that it is foamable. Typically, the oils utilized in the present invention are present in the formulation in a percentage of 40 to 95% by weight of the total composition." A preferred range is 50 to 70% by weight of the total composition. The amount of oil may be varied based upon the nature and amount of the other ingredients in the formulation, such as the amount of dispersed solids. Ordinarily, the percentage amount of each other ingredient in the formulation is first selected and the oil is the ingredient -added to bring the formulation to 100%. • Foaming. agents utilizable in the present invention are selected from the group consisting of lecithin, various polyol fatty acid esters and mixtures thereof, or solid silicone copolymers as disclosed in U.S. Patent No. 3,770,648. Lecithin is the commercial name for a class of naturally occurring compounds derived from soybeans. These compounds are phosphatides and phospholipids. The principal components of lecithin are a naturally occurring mixture of phosphatidyl choline, phosphatidyl ethanolamine, inositol phosphatides and related phosphorous containing lipids. Chemically, lecithin is described as phosphatidyl choline and is a mixture of the diglycerides of stearic, palmitic and oleic acids linked to the choline ester of phosphoric acid. It is available commercially as a 60% solution in soybean oil or as a granular powder essentially free of soybean oil. A hydroxylated lecithin, modified to increase the hydrophilic properties is also commercially available.

This hydroxylated lecithin is commonly supplied as a 60% solution in soybean oil.

The polyol fatty acid esters utilizable in the present invention are commercial products and are comprised of three types:

1. Glycerol esters of fatty acids.

2. Polyglycerol esters of fatty acids.

3. Sorbitan esters of fatty acids.

The glycerol esters which have been found to be advantageous in generating a suitable anhydrous aerosol foam are prepared by standard esterification methods and have a HLB of between 2.5 and 4.5. Among the preferable glycerol fatty esters utilizable in the present invention are those such a glycerol monostearate (HLB 3.2) and glycerol monooleate (HLB 3.4).

The polyglycerol esters utilizable in the present invention are commercial products prepared by first polymerizing glycerine under alkaline conditions. The polymerization is controlled to yield the particular desired average molecular weight. Investigations indicate that the polymerization of glycerol progresses predominately in a straight-chain manner. The esters are prepared by reacting the polyglycerols with a specific fatty acid or by the alcoholysis of a triglyceride. By this method, it is possible to prepare esters ranging anywhere from hydrophilic monoesters such as decaglycerol monolaurate to a lipophilic decaglycerol decaoleate.

The polyglycerol esters preferably used in the present invention have an HLB value of between 4.0 and 13.0. These have been found to be most advantageous in generating a suitable anhydrous aerosol foam. Among the preferable polyglycerol esters utilizable in the present invention are those such as: hexaglycerol distearate (HLB 4.0), decaglycerol tetraoleate (HLB 6.0), triglycerol monostearate (HLB 7.0), triglycerol monooleate (HLB 7.0), octaglycerol monostearate (HLB 12.0) and octaglycerol monooleate (HLB 13.0).

The sorbitan fatty acid esters which have been found to be advantageous in generating a suitable anhydrous aerosol foam are commercial products prepared by standard esterification methods and have an HLB of between 3.0 and 7.0 Among the preferable sorbitan esters utilizable in the present invention are those such as sorbitan monostearate (HLB 4.7), sorbitan monooleate (HLB 4.3), and sorbitan mono palmitate (HLB 6.7).

Additionally, a combination of any of the polyol fatty acid esters may be utilized in the present invention,

The polyol fatty acid esters are somewhat more hydrophilic than lecithin so that their use allows the foamable, anhydrous liquid oil to be more easily dispersed when contacted with an aqueous medium. Additionally, they may be used in conjunction with lecithin in the same system which causes the lecithin to become more hydrophilic and therefore more water miscible than the lecithin alone.

The solid silicone copolymers which are useful as foaming agents in this invention are fully disclosed in U.S. Patent No. 3,770,648 and that disclosure is hereby incorporated by reference.

The foaming agent utilized in the present invention is present in an amount of from 2 to 40% by weight. The amount of foaming agent utilized depends upon the particular foaming agent being utilized, the particular foamable, anhydrous liquid oil being utilized and the propellant system. A preferred range of foaming agent is from about 3 tO 15% by weight of the composition, with 4 to 6% being especially preferred. It is a particularly desirable additional feature of the foaming agents that they possess surfactant properties and, therefore, affect the rate at which the insoluble solid active ingredient of the foam is released. Accordingly, some variations in the amount of foaming agent in a particular formulation may be purposely chosen based on the nature of the solid active ingredient in order to control the rate of release.

The propellant can be selected from the class of hydrocarbons that are gaseous under atmospheric pressures and liquefy when compressed, or certain fluorocarbons such as FREON 115; monochloropentafluorethane; FREON 12,' dichlorodifluoromethane; Dymel 22; chlorodifluoromethane; Dymel 152; 1, 1, difluoroethaane; and dimethylether.

Propellants other than the liquefied hydrocarbon or fluorocarbon gases can be used including compressed gases like nitrogen, nitrous oxide and carbon dioxide, but they do not produce the most desirable foams over the life of the product in use. The most commonly used propellants are propane, butane and isobutane. Since these liquefied gases are soluble in the oil vehicle of the composition, there is a resulting reduction in their vapor pressure. Therefore, it is most advantageous to use- propane since it has the'highest pressure of the three hydrocarbon propellants and, even when dissolved in the low concentrations normally employed in this invention, produces a product with a pressure of 30-40 pounds per square inch over atmospheric pressure. This pressure is required to eject the foam from the container and produce a stable, dense foam. However, since propane is soluble in the oil base, there is very little pressure drop from the first to the last actuation of the aerosol valve and a satisfactory foam is produced when each dose is expelled. The amount of propellant used is critical since too much will produce an undesirable spray rather than the desired stable, measurable foam. Amounts of propellant in the range of from 1-10 wt. % are operative, but 4-6 wt. % is the preferred concentration based upon the total weight of the contents of the aerosol container. The amount of propellant used may vary somewhat, depending upon the nature and amount of the other ingredients in the composition but, in all cases, the lowest amount sufficient to form a stable, measurable foam without forming an unmeasurable spray will be selected.

The anhydrous solid particulate matter capable of sorbing water exothermally which can constitute between 10 and 50% by weight of the basic composition, includes any materials in this class which are physiologically compatible with hair and skin and which are further compatible -with any pharmaceutically active agents to be added to said basic composition. In this general category may be included calcium chloride, silica gel, activated alumina and alkali metal alumino silicate molecular sieves. The latter generally being know as Zeolites. Of particular interest, are the Zeolites, especially those of the general formula Mx/n[

Figure imgf000011_0001
, wherein X and Y are integers greater than 6, the molecular ratio of X to Y is 0.1 to 1.1 and M is a metal with a valence of n. These Zeolites are preferably in the activated foam which effectively means that they have been pretreated in such a manner that they contain not in excess of 5% by weight of water.

The anhydrous aerosol foam of the present invention may be used as a vehicle for any of a large variety of active pharmaceutical materials or cosmetic ingredients in addition to the exothermic material.

The foam itself may be used as a carrier for a large variety of additional hair or skin modifying agents. Such modifying agents may be cosmetics or pharmaceuticals and may include both prescription and non-prescription agents. Thus, there may be incorporated hair dyes and hair conditioning agents, shampoos, shaving soaps, skin emollients, anti-dandruff agents, anti-seborrheic agents, anti-inflammatory agents, muscle relaxants, and any other generally accepted agents for modifying the condition of hair, the surface of the skin and su'bdermal areas generally treated by topical application.of physiologically active materials. As examples' of conditioning agents, there may be mentioned the quaternary salts of fatty acids having a carbon content of 12 to 18 carbon atoms, generally accepted conditioning oils such as isopropyl myristate, isopropyl palmitate, isopropyl sebacate and the like may be used; as anti-dandruff agents, there may be utilized zinc pyrithione or selenium sulfide; as anti-seborrheic or anti-inflammatory agents there may be mentioned hydrocortisone; as hair dyes any of the conventionally used hair dyes may be employed. This list is to be considered as merely illustrative and in no way limiting. Additional agents not listed herein would be apparent to those skilled in the art.

The amount of these added agents will depend upon the required effective concentration and whether they are solid or liquid. If they are liquid, they may constitute up to 95% of the total composition by weight, although 20 to 65% is to be preferred. If they are solids, they may constitute up to 40% of the total composition, provided that the combined proportion of the anhydrous solid particulate material and said solid agent does not exceed 50% of the entire composition.

A particularly important and surprising feature of the foams of this invention is their ability to suspend high concentrations, i.e., up to 50% by weight, of solids. Preferably, th.e suspended particles are ground to a very fine particle size since this facilitates the formation and maintenance of a uniform dispersion and prevents clogging. Particle sizes less than 100 microns, preferably in the range of 50 to 100 microns in diameter, are employed. ' The foam of the present invention can contain up to 50 wt. % of suspended solid particles without any appreciable valve malfunctioning, and will usually contain in excess of 15 wt. % of such solid particles since a primary purpose of the foam system is to deliver a high concentration of the active ingredient in the solid particles in a relatively small dose. This ability to suspend high percentages of solids without valve malfunctioning enables the aerosol foam system of the present invention to be utilized for a wide variety of formulations. The reasons for the unique ability of the foams to suspend such a high concentration of solids without valve clogging are not fully understood, but it is believed to result from a combination of the small particle size, the high viscosity of the foam formulation due to its low propellant content which aids in keeping the particles dispersed and reduces agglomeration and settling, and the lubricating effect of the oil on the valve.

The foams of the present invention are prepared by conventional formulating techniques. Thus, typically, the foamable anhydrous liquid oil and- the foaming agent are mixed together along with any other soluble ingredients of the composition. The solid to be dispersed is then added and the resultant mixture passed through an appropriate mill to ensure uniform particle size. The batch is then submitted for aerosol filling to an aerosol can. An aerosol valve is placed on the can and the can is crimped. The propellant is then added by pressure filling.

In addition to the active solid to be dispersed in the foam and the essential ingredients of the foam, there may also be incorporated in the foams of the present invention any of a variety of additives or a combination thereof, commonly added to aerosol compositions or to toiletries, cosmetics, or pharmaceuticals. Typically, such additives are those such as emollients, lubricants, humectants, abrasives, perfumes and colorants.

It will be apparent to those skilled in the art that many modifications, both of materials and methods, 5 may be practiced without departing from the purpose and intent of the disclosure.
