United States 2,996,432 SKIN TREATING COMPOSITION AND METHOD John P. Modderno, Gambrills, Md., assignor to Modem- Lab., Incorporated, Baltimore, Md., a corporation of Maryland No Drawing. Filed Apr. 7, 1961, Ser. No. 100,786 Claims. (Cl. 167-90) This invention has as an object the provision of new and a paste-like liquid form to parts of the body, especially the external surface thereof, and capable of solidifying in situ to form a mask, covering, or the like, and to the method of dispensing and applying these compositions and to the products formed therefrom. More particularly, this invention relates to treating compositions employing a gel type material, such as an alginate or rubbery material with protective colloid, as the base material for forming facial masks capable of cleansing, astringing, and applying beneficial oils, moisture, etc., to the skin, protective coverings, or the like.
This application is a continuation-in-part application of my co-pending U.S. applications Serial No. 611,386 and Serial No. 526,076, filed September 21, 1956, and August 2, 1955, respectively, Serial No. 611,386 being a continuation-in-part of Serial No. 526,076.
Many compositions have been heretofore known in the art for application to the human body, for example, facial treating compositions, and the like, for forming treating masks on the face. These compositions, however, have not been adaptable to convenient methods of application and have required the mixing by hand of several ingredients by the person applying the composition at the time of use. In addition, these compositions, when applied to the face or other parts of the body, have not been capable of setting in relatively short periods of time, which is a feature that is essential to the comfort of the person treated and to the effectiveness of the composition. Also, these materials when set have not been capable of effecting a beneficial treatment by remaining in a moist condition and sufiiciently porous to allow breathing of the skin during treatment, all of which is essential to comfortable and effective skin treatment by the use of a mask.
This invention contemplates the use of compositions comprising an aqueous solution of an alginate or a colloidal emulsion of a rubber-like substance either with or without an alginate, together with suitable fillers, and compounds capable of producing multivalent metallic ions as the basic ingredients constituting a dispensable or applicable facial composition which, when applied to the skin, will set in situ to form a facial mask or covering. The mask or covering so formed provides a facial treating medium which contains therein beneficial ingredients that are constantly applied to the skin by the medium of the mask or covering while maintaining the skin in a moist and relaxed condition without impeding facial skin respiration.
The present invention also includes the method of dispensing the facial treating composition from an aerosoltype container by the use of argon gas or a mixture of an argon gas and a gas more soluble with the composition, for example, nitrous oxide, as a propellant.
It has also been found that the compositions of this invention can be stored for substantial periods of time in compartmentalized containers in which the liquid ingredients are separated from the solid ingredients by an impervious diaphragm or the like and the can pressurized with an insoluble gas, such as argon or the like, so that puncturing the diaphragm permits the solids to mix with the liquid under the pressure of the gas, thereby forming an aerosol or gaseous-dispensable product.
This invention has as an object the provision of new and valuable compositions capable of being applied to the human body to form thereon a capable of providing beneficial treating effects.
Another object of this invention is to provide a composition having as its basic ingredients a rubber-like emulsion either with or without a soluble alginate together with a filler material and a compound or compounds capable of providing multivalent metallic ions which, when applied to the human body, will solidify in situ to form a beneficial treating mask or covering thereon.
A further object of this invention is to provide a composition for application to the external surface of the human body. When the composition is applied to the face, for example, in a cleansing or beauty treatment, it solidifies at a controlled rate in order that as little inconvenience as possible will be experienced by the person being treated. To this end, the composition is prepared so that it will not have irritant qualities and at the same time When set on a persons skin or face, particularly in the form of a mask, will have the requisite astringent, cleansing and soothing qualities. The nature of the composition is such that it will form a stifi elastic gel in situ closely adhering to all portions of the face being treated and without in any way irritating the skin.
Still another object of this invention is to provide a facial treating composition in which the emulsified ingredients are separated from the solid ingredients in a compartmentalized container in the presence of a propellant such as argon gas so that, upon mixture of the solids and the liquid, a dispensable composition is produced which is capable of being dispensed with a minimum of foaming and which will gelate at a controlled rate on the face to form a beautification mask.
Other objects of the invention will be apparent from examination of the specification and claims.
According to one aspect of the invention, an emulsion and a powder in proper proportions one to the other for forming the desired composition are kept in separate compartments, separated by a diaphragm, in a pressurizable container until the composition is to be used. The emulsion contained in one compartment has as its principal ingredients a natural or synthetic latex or a resin latex together with an accelerator, defoamer, and a surface activating agent. The powder is kept in the other compartment above the emulsion and separated from the emulsion by the puncturable diaphragm which is impervious to either the emulsion orthe fine particles of the powder. The powder has as its principal ingredients a protective colloid, a suitable filler, a buffering agent, and a compound capable of supplying multivalent metallic ions. There is further included in the facial composition substances having astringent, tonic and cleansing qualities, and there may be mentioned in this connection calcium oxide, alum and hamamelidin and liquid castile soap. The first two mentioned substances have astringent properties and in addition function in the final composition as binding agents. The hamamelidin, more commonly known as witch hazel, possesses in addition to its astringent properties, tonic qualities. Liquid castile soap enhances the cleansing action. In addition to the above ingredients, there may be added to the composition various other substances, as for example, perfume, menthol to serve as a cooling agent, and eucalyptus oil to serve as a soothing agent. The container and contents are pressurized by an inert gas, preferably aninert gas which produces a minimum of foaming, such' as argon.
When application of the composition is desired, the diaphragm separating the powder from the emulsion is punctured, thereby allowing the powder to mix with the emulsion under pressure of the inert gas which supplies gelated mask or covering the propellant force to dispense the composition from the container ready for its intended use.
Separation of the emulsion and the powder by the impervious diaphragm allows forrprolonged storage so that, when needed, the composition can be automatically mixed zfmd dispensed as a ready-to-use product in the desired orm.
. It'has been found that argon gas constitutes an excellent propellant and dispensing agent for the compositions of this invention. It has also been found that argon constitutes an aerosol propellant which will dispense the product with aminimumof foaming. Control of foam.- ing may be important where it isfpreferredthat the composition to be dispensed shall have a creamy consistency having a minimum number of bubbles therein. Argon gas has been found to be the propellant gas that is least soluble in the compositions of this invention and consequently the use of such a gas makes it possible to dispense a heretofore undispensable composition. 7
It is apparent that the compositions described above, if storage is not required, can be mixed and applied directly, as in the case of treatment of the face by brushing or patting on with the hand.
Some specific examples of suitable compositions are as follows:
. Example 1 Emulsion:
80 cc. 1 cc. '4 cc. 300 cc.
. i 385 cc. emulsion Powder:
10 g. 60 g. 10 g. 1.4 g.
The powders are blended in a ball mill to bring about intimate mixing and dispersion of the various ingredients throughout. Ninety-five cc. of the emulsion are placed in the bottom of an aerosol-type container. An impervious diaphragm is placed over the emulsion so as to separate the container into two compartments. 20 grams of the powder from the ball mill are placed in the top part of the container. The top of the container is then sealed so that the diaphragm or membrane separates the liquid from the powder and forms within the container two separate compartments. The container is charged with argon gas to about 30 psi. through the valve in the telescoping plunger head of the aerosol-type container. In this condition, the container and its contents are ready for storage.
After the container thus prepared is stored for a short time, the telescoping head is pressed down so that the end of the telescope punctures the diaphragm allowing the powder to mix with the emulsion to form the desired composition under the pressure of the argon gas. The release valve on the head is prmscd and the contents of the can are propelled from the can ready for use as a composition having a creamy consistency having the desired pliability. This composition gelates within a period of three minutes into a strong elastic mask when applied to apersons face.

Dow-Corning silicone anti-foam 1 cc. Z-ethylhexanol 300 cc; water 382 cc. emulsion Ninety-five cc. of this emulsion and grams of the powder described in Example 1 are placed in a container as described in Example 1, and the resulting composition, when dispensed from the aerosol container, produces a composition which soon'coagulaltes or gels on a persons face to a strong elastic mask which thereafter may readily be peeled from the face. 7
Natural or synthetic latices may be coagulated or gelled by two basic methods: 1
(l) Coagulation by dehydration (the removal of water) where by a drying method the particles approach each other and finally make contact. Latices may also be coagulated or gelled by the use of an organic solvent, such as alcohol or acetone. This is another form of dehydration.
(2) The second method of coagulation or gelling a natural or synthetic latex is by the reduction of the particle charge. Coagulation by reduction of the'charge on the particles can be brought about in several ways, such as by the addition of acid (alginic acid), salts, compounds yielding bior tri-valent metal ions or surface active agents, etc. The salt, for example, may be potassium acid phthalate or tetrasodium pyrophosphate; the
- styrene; neoprene esters, polyamides, plasticized multivalent metal ion compound may be calcium sulfate or the like; the surface active agent may be Z-ethyl hexanol.
The second method is preferred in the practice of this invention, but either method can be used.
Exemplary of the rubberlike substances that may be used to form the emulsion are natural rubber latices produced by the hevea tree; G.R.S. latices which consist of polymers of butadiene or copolymers of butadiene and latices which are polymers of chloroprene and other polymerizables, the major constituent of which is chloroprene; nitrile latices which are copolymers of acrylonitrile and butadicne; and resin latices of a large variety including polyacrylic acid esters and polyand unplasticized polystyrene, polyvinyl butyrals, plasticized and unplasticized polyvinyl chloride polymers and copolymers, plasticized and unplasticized polyvinylidene chloride, and polyvinyl ester plastic emulsions, and the like.
Other ingredients used in the emulsion are plasticizers (e.g., diethyl phthalate, dimethyl phthalate, dibutyl phthalate); defoamers '(e.g. silicones, silicone emulsions, Nopco 1497VNopco Chem. Co., Foamrex S-Socony- Vacuum, andhigher aliphatic alcohols); surface active agents (e.g., Z-ethylhexanol, undecanol, and Amerchol L-l0l which is a liquid multi-sterol non-ionic surface active penetrant, emollient and emulsifier. The sterols present in Amerchol L-l0l are cholesterol, agnosterol, lanosterol, dchydrocholesterol, and cerebrosterol, present in their free formsas the alcohols; and accelerators (e.g., zinc dimethyl dithiocarbamate).
It is to be understood that the protective colloids can either be incorporated with the emulsion or can be mixed with the powder, as desired.
The powder formulation contains protective colloids, such as those which are essentially derivatives of alginic acid (e.g., potassium, sodium or ammonium alginate, triethanolamine alginate), Irish moss derivatives, various other seaweed derivatives, carboxymethyl cellulose, carboxyethyl cellulose, methyl cellulose, water-soluble polyelectrolytes, guar gums, caseinates, polysulfates, agaragar, etc. Multivalent metallic ion containing com pounds used in the powder formulation may be calcium sulfate, lead monosilicate, and the like. Buffering agents used may be trisodiumphosphate, tetrasodium pyrophosphate, polyphosphates, sodium acetate, anhydrous sodium carbonate, and the like; and fillers used may be diatomaceous earth, kaolin, ground limestone, calcium carbonate, powdered asbestos, magnesium silicate silica, magnesium carbonate, fullers' earth, precipitated chalk, and the like.
materials for mixing with the emulsion water to form the desired facial compositions.
Suitable compositions containing the protective colloid in the emulsion include the following:

The compositions of this invention, when applied to the surface of the body, for example the face, will, after a short period of time, usually 2 to 5 minutes depending on the ingredients used, form in situ a gel'ated covering or mask which fits snugly to the face. From this mask exudes the beneficial treating ingredients such as oil, astringent, antibiotics, etc., which are incorporated with the composition and are adsorbed by the pores of the skin, thereby causing a cleansing and revitalizing action.
The mask formed from the compositions of this invention, when set on the face and allowed to remain for periods of about 20 to 30 minutes, maintain the covered skin in a moist condition while permitting respiration of the skin. The result of the treatment with the mask is a facia in ne app cation or step, which heretoims 7 application simply by the formation of the beneficial treating mask on the face.

The powders set forth above in Example 3, but with the tetrasodium pyrophosphate content doubled, were each mixed with one of the emulsions set forth' in EX- amples 7, 8, and 9 in the manner described in Example 1. The resultant dispensed product of each of these compositions was applied to the face to form a facial mask. It was found that the mask 'gelated in situ within a period of threeto five minutes and, after application for a period of'about 30 minutes, the mask peeled easily from the face, leaving the "skin cleansed, toned, and revitalized.
The time for setting the mask can be controlled by varying the amounts of the accelerator added to the composition so as to allow the person applying the mask time in 'which'to apply the composition to form the desired mask or'covering on the body. 7 It is pointed out that the protective colloids described above are used in the above compositions to enhance their shelf life and these may be incorporated in either the emulsion or the powder or in both. The principal gelforming ingredient in the above compositions is a latex of a rubberlike composition. The following Example 10 shows compositions of this invention but without the use of protective colloids, such as an alginate, to enhance shelf life:
The powders set forth above in Example 3, but with the tetrasodium pyrophosphate content doubled, were each mixed with oneof the emulsions set forth in Example 10 in the'manner described in Example 1. The resultant dispensed product of 'eachof these compositions was applied to the face to form a facial nnask. It was found that the mask gelated in situ within a period of 3 to 5 minutes and, after application for a period of about 9 30- minutes, the mask peeled easily from the face leaving the skin cleansed, toned, and revitalized.
The compositions set forth in the invention can be used as padding, resilient protective covering, surgical covering, and the like, for the body, by varying the ingredients as described above and by including other beneficial agents, such as medicaments, antibiotics, burn remedies, antihistamines, cortisone, antiseptics, genmicides, anesthetics, etc.
Other solids which normally would be incompatible with the powdered ingredients mentioned above when stored for a substantial period of time may also be incorporated by providing still another compartment in addition to that separating the emulsion and the powder. The puncturing of the film separating the powders, the incompatible solid ingredient, and the emulsion will produce the composition desired.
Considering another aspect of the present invention, any of the salts of alginic acid, such as sodium, potas sium or ammonium alginate, which are soluble in water and possess hydrophilic colloidal properties, may serve as one of the basic ingredients for the formation of the gel in situ when calcium sulphate or other multivalent metal ion-producing salt is incorporated in an aqueous solution of the alginate in the presence of a suitable filler, and preferably also with another salt such as sodium carbonate or the like to assist in controlling the gelling time of the alginate.
It has been discovered that an aqueous solution of an alginate when combined with calcium sulphate, and preferably anhydrous calcium sulphate, or other water-soluble salt of a multivalent metal and an inert filler such as calcium carbonate forms a stilf elastic gel. Sodium carbonate may also be employed in the composition, the sodium carbonate assisting in controlling the time in which the gel will set. Anhydrous sodium carbonate is preferably employed. These compositions, because of their unique properties, are well suited for use as a base for facial treating compositions having cleansing and softening properties.
Essentially then, a composition such as this is comprised of an alginate, such as sodium, potassium or ammonium alginate and the like, with sodium alginate being preferred, admixed with an inert filler and a water-soluble salt of a multivalent metal, such as anhydrous calcium sulphate. Anhydrous sodium carbonate and the like substances capable of assisting in controlling the formation time of the gel are also desirable components of these compositions. The inert filler is an inert factor in the composition and fimctions as a binding agent to give body to the composition when the gel is formed. This inert factor or inert filler may be powdered asbestos or clay or other similar material so long as it does not possess irritant qualities. There is further included in the composition substances having astringent, tonic and cleansing qualities and there may be mentioned in this connection calcium oxide, alum and hamamelidin and liquid castile soap. The first two mentioned substances have astringent properties and in addition function in the final composition as binding agents. The hamamelidin, more commonly known as witch hazel, possesses in addition to its astringent properties, tonic qualities. Liquid castile soap enhances the cleansing action. All of the abovementioned compounds have astringent, cleansing or tonic properties and impart to the skin a beneficial treatment when the mask solidifies in situ on the face. In addition to the above mentioned compounds, perfumes, rose water, menthol, eucalyptus oil, and many other like substances can be employed in small quantities so that when the mask has solidified in situ these components which are beneficial treating agents are imparted to the skin where they effectively treat the face in a beneficial manner.
The above mentioned materials, namely the aqueous solution of the water-soluble salt of alginic acid, the
water-soluble salt of a multivalentmetal, the gelling time controlling agent, and a suitable inert filler, are kept in a pressurized can or plastic container until such time as it is desired to apply the composition at which time it is dispensed from the container and the resulting composition is applied to the area of the skin of the individual undergoing treatment in the form of a mask. The dispensed composition, in the form of an aqueous solution, upon application to the face and after a predetermined period of time, gels and sets, the active factors of the composition working to cleanse and soften the skin. When the gel formation has been completed, the mask is then stripped from the skin and the treatment is then concluded in the usual fashion.
In addition to the above ingredients, there may be added to the composition various other substances, for example, perfume, menthol to serve as a cooling agent, and eucalyptus oil to serve as a soothing agent.
Broadly the range of proportions of the various ingredients, according to this aspect of the invention, may be as follows:
Parts by weight Alginate 5 to 20 Inert filler 30 to Astringent 1 to 8 Anhydrous sodium carbonate, calcium sulphate 1 to 20 Liquids 5 0 to 250 A preferred range of proportions of the several-ingredients is set forth as follows:
Parts by weight preferred Further, the preferred composition, according to the present invention, is set forth in the following table:
Parts by weight preferred Alginate 10 Inert filler 65 Astringent 3 Anhydrous sodium carbonate, calcium sulphate 5 Liquids It will be evident from the above preferred composition that there are essentially 83 grams of powder to about 125 grams of liquid which is predominantly distilled water for one application. The formula may be varied depending on the size or number of applications.
To appreciate more fully the nature and scope of this aspect of the present invention, there follows examples of still other formulations prepared in accordance with the invention:

As mentioned above, the anhydrous sodium carbonate or the like serves as a convenient timer to assist in controllin'g the tiine in'which the gel sets. The anhydrous nature of the calcium sulphate or the like may also be employed, although somewhat less conveniently, to control the time of gelation. As a rule of thumb, it can be said that for each gram of anhydrous sodium carbonate or anhydrous calcium sulphate, it will take the composition one minute to set. It is normalh considered undesirable if the treatment is of too brief a duration as will result if the composition sets too rapidly. By the same token, it is also considered undesirable for the treatment to be unduly prolonged which will result if the composition sets over too long a period of time. -It has been found that the composition should set in less than about twenty (20) minutes and not before about three (3) to five (5) minutes.
It is to be understood that the invention is not limited to the specific proportions set forth or the ingredients referred to above. Any changes or modifications obvious to one skilled in the art are deemed to be within the spirit and scope of the invention.
