Description

SPECIFICATION Volatile Silicone Water Emulsion and Methods of Preparation and Use Background of the Invention The present invention discloses compositions of matter and methods for producing stable silicone-water emulsions of voltatile cyclic polysiloxanes without the need for milling or homogenization and which are particularly useful in cosmetic and medicinal applications.
The silicone-water emulsion composition of the present invention is particularly well-suited for serving as a vehicle for the application of epidermal enhancing agents. The expression "epidermal enhancing agents" refers to those compositions having properties generaliy considered as being beneficial when applied to portions of the body. For example, such agents include a wide range of cosmetics and medical and pharmaceutical compounds.
In the cosmetic category there are many types of products which can be beneficially applied to the skin in a silicone emulsion form. For example, such cosemetics would include cream eye shadows, foundations, blushes, lip gloss, mascara and eyeliner, cover-up-type compositions and wrinkle creams, moisturizers, acne cover-up, depilatories and cuticle removers, etc.
Such emulsions can also be used for cleansing purposes and may take the form of shampoos, soaps, conditioners and moisturizers. Additionally, hair dyes may be applied in a silicone-water emulsion vehicle.
Additional cosmetic uses include the application of perfumes, colognes and sachets to the body. Among the particularly useful applications would be deodorants and antiperspirants.
Among the many medical uses of such an emulsion vehicle would be first aid uses such as burn ointments and the application of antiseptics.
Furthermore, corn, wart and callous removing agents, for example, can be successfully applied to the skin in such a silicone-water emulsion vehicle.
Of course, the consistency of the siliconewater emulsion of the present invention can be varied through many degrees from a lotion-like consistency through cold cream-like pastes up to gel-type ointments or salves on the order of a petroleum jelly.
Silicones are synthetic polymers ordinarily commercially prepared from chlorosilane monomers and available in the form of fluids, resins and rubber gums. Of particular interest to the cosmetic industry are those polymers formulated into emulsions, greases, pastes, etc. In these formulations a wide variety of materials may be used in conjunction with the silicones.
Monomeric chlorosilanes are very reactive volatile materials which readily react with moisture to form silicones and byproduct hydrochloric acid. Thus, in the presence of moisture they are considered corrosive materials and may have hazardous properties and must be handled with care. However, after processing into silicone polymers these materials become bland and inert substances. Silicones may be further formulated with other materials to produce various end use compositions and often the physiological effect of the finished composistion is determined by the nature of the non-silicone component.
The toxocological properties of silicones have been widely studied and, as a group, polymeric silicone fluids and resins ordinarily have a very low order of toxicity. Considered from a practical viewpoint, the hazards they present are exceedingly minor. Silicone fluid polymers have been the subject of skin irritation and sensitization patch test studies and are typically shown to be safe. The low level of toxicity of silicone materials has even lead to the acceptance and successful use of silicone fluids in medical and dental applications.
Silicone fluids generally provide excellent protection against water-borne irritants such as harsh detergents and other household cleaning specialties. The chemical inertness and excellent water-repellency of silicone fluids are the major reasons for their effectiveness in preventing dermatitis. Silicones may also function as emollients, and provide a pleasant non-stick "feel". Superior suntan lotions and creams can be prepared using silicones, since the silicone fluid is a carrier for the sunscreening agent and resists wash-off by either bathing or perspiration.
Emulsions containing volatile silicone cyclic polysiloxanes have been previously formulated by utilizing emulsifying agents such as dodecyl benzene sulfonic acid, however, these systems require milling or homogenization in order to emulsify the immiscible phases. It is possible to emulsify preparations of this type having only up to about 55% concentration of voltatile cyclics and emulsions of this type are frequently utilized to carry out emulsion-type polymerization of cyclic such as octamethyltetrasiloxane.
The present invention provides a method which makes it possible to emulsify larger concentrations of cyclic polysiloxanes while at the same time eliminating the necessity of milling or homogenization. Additionally, the present invention provides stable emulsions of cyclic polysiloxanes such that these emulsions do not ordinarily "break" under normal storage and use conditions even when the concentration of volatile cyclic polysiloxane is 80% or more. This is a particularly useful property for consumer oriented products since these emulsions can therefore, ideally be utilized as vehicles for conveying epidermal enhancing agents onto the skin of a user in a beneficial manner.
Furthermore, the present invention offers a system for emulsifying volatile cyclic polysiloxanes which yield opaque to transparent materials, which can be readily formulated into many consumer products and particularly antiperspirants and deodorants, etc. Other potential uses for water based cyclic emulsions are skin care products such as hand lotions, skin fresheners, hair preparations and other grooming aids. As noted above, the method of the present invention provides a means for selectively varying the consistency of these emulsions depending upon the ultimate purposes of the product.
An additional advantage resides in the fact that these silcone-water emulsions are comprised of relatively volatile cyclic polysiloxane constituents such that an emulsion vehicle base will eventualiy evaporate from the skin and only the beneficial epidermal enhancing agent will be left thereon.
Summary of the Invention The present invention provides a silicone-water emulsion and methods of preparation and uses wherein said emulsion comprises: (A) 100 parts by weight of a cyclic polysiloxane or a combination of cyclic polysiloxanes selected from those having the general formula, 1
wherein n is an integer from 3 to 10, R is selected from the group consisting of -CH3, (CH2)zCH3, -CH2CH2CF3, -CH 2=CH2,and andCeH5 and combinations thereof and z is an integer from 1 to 10; (B) from 0.7 to 666 parts by weight of an emulsifier; and (C) from 5.0 to 960 parts by weight of water; and stirring with moderate heat until an emulsion having a desired consistency is produced.
Description of the Invention The present invention provides a silicone-water emulsion, which is comprised of 100 parts by weight of a cyclic polysiloxane or a combination of cyclic polysiloxanes having a general formula,
wherein n is an integer from 3 to 10, R is -CH2, -(CH2)2CH3, -CH2CH2CF3, -CH2=CH2, or --C,H, or combinations thereof and z is an integer from 1 to 10. The polysiloxanes designated by this formula are known as volatile silicone cyclics and this property of volatility imparts advantageous properties to the emulsion composition. Particularly useful volatile silicone cyclics are octamethyltetrasiloxane and decamethylpentasiloxane.
The volatile cyclic polysiloxane is combined with an emulsifying agent and water to form a silicone-water emulsion. The order of mixing the ingredients is not critical, however, particularly satisfactory results can be obtained when the emulsifying agents and the water are mixed together in a preblend to which the volatile cyclics are added.
Preferably, the cyclic polysiloxane is added to a preblend consisting of approximately, 50 to 200 parts by weight of water, which is mixed with 100 parts by weight of one or more emulsifying agents and heated until a uniform blend is achieved.
This preblend is suitable for producing a pastelike silicone-water emulsion, however, if a more liquidous or lotion-like consistency is desired, there may range up to 2,000 or more parts water per 100 parts of the emulsifying agents. The emulsifying agents may be nonionic, anionic, cationic or amphoteric but of particular importance are those classes of nonionic emulsifiers which are highly ethoxylated. The ethoxylated fatty acids, ethoxylated and nonethoxylated sorbitan esters, ethoxylated alkyl phenols, and ethoxylated ethers provide the best results.
Examples of emulsifiers which may be used to formulate the silicone-water emulsions of the present invention are included in but not limited by the following list: 1) ethoxylated fatty acids like: polyoxyethylene 8 stearate polyoxyethylene 40 stearate polyoxyethlene 50 stearate 2) sorbitan esters like: sorbitan monolaurate sorbitan monopalmitate sorbitan monostearate sorbitan tristearate sorbitan monooleate sorbitan trioleate 3) ethoxylated sorbitan esters polyoxyethylene (20) sorbitan monolaurate polyoxyethylene (4) sorbitan monolaurate polyoxyethylene (20) sorbitan monopalmitate polyoxyethylene (20) sorbitan monostearate polyoxyethylene 20 sorbitan tristearate polyoxyethylene 20 sorbitan monooleate polyoxyethylene 5 sorbitan monooleate polyoxyethylene 20 sorbitan trioleate 4) ethoxylated ethers like: : polyoxyethylene 4 lauryl ether polyoxyethylene 23 lauryl ether polyoxyethylene 20 cetyl ether polyoxyethylene 10 stearyl ether polyoxyethylene 20 oleyl ether 5) ethoxylated alkyl phenols like (alkyi phenoxy polyoxyethylene glycol) (CeH,7CeH4) (OCH2CH2)nOH CAS #9036-19-5 (C9HtgCeH4) ( CH2cH2)n H CAS #26-27-38-3 Approximately, 1 5 to 50 parts by weight of this emulsifier-water preblend is added per 100 parts by weight of the cyclic polysiloxane when a pastelike silicone-water emulsion is desired.
Up to approximately, 1000 parts of this preblend can be added per 100 parts of the volatile cyclic polysiloxane inorder to provide a low viscosity, lotion-like product.
By adjusting the various process parameters such as content of the volatile cyclic polysiloxane, emulsifying agent, and water as well as the degree of mixing, it is possible to influence the consistency of the product. The silicone-water emulsion can be made in the form of a lotion as well as a paste or cream-like consistency and can be made further viscous in the form of an ointment, salve or a gel. Each of these consistencies is of course, chosen with regard to the desired end use of the product.
The silicone-water emulsions useful as a vehicle for applying from 0.1 to 20,000 parts by weight of one or more epidermal enhancing agents per 100 parts of the emulsion.
This broad range is intended to encompass those products consisting of nearly pure siliconewater emulsion having a small amount of epidermal enhancing agent contained therein, as well as other products which have but a small amount of silicone-water emulsion contained therein. Epidermal enhancing agent refers to an additive of a cosmetic or medicinal nature which is generally regarded as providing beneficial results when applied externally to the skin of a user. The silicone-water emulsion of the present invention is particularly well-suited to serve as a vehicle for applying deodorant or antiperspirant agents to the body.
The preblended water-emulsifier mixture is provided by stirring with moderate heat until a uniform blend is obtained whereupon the cyclic polysiloxane is added and mixed slowly without the need for milling or homogenization. Of course, milling and homogenization may be utilized if desired and it is intended that the term "mixing" encompasses these methods as well as mere agitation. Thus, the expression "mixing" is meant to encompass a continuous process utilizing, for example, a Wener-Pfleiderer wherein individual streams of the components can be metered into a twin screw processor. Likewise, a Henshel high speed mixer, a sonolator homogenizer with a vibrating reed and a plain vessel equipped with a mechanical agitator turbine blade will all produce satisfactory results.The silicone-water-emulsifier mixture is then vigorously stirred at 20 to 800C until an emulsion having a desired consistency is achieved. An anti-bacteria agent such as Formalin may be added if desired.
To a 2 liter stainless steel beaker equipped with a hot plate, mechanical air stirrer and thermometer, the water and emulsifier are preblended by adding together and heating to approximately 20 to 800C and preferably 65 to 750C and stirred to achieve a uniform mixture when all the solids have melted. Then the volatile cyclic polysiloxanes, which may be octamethyltetrasiloxane or decamethylpentasiloxane or a combination of these or others are slowly added to the aqueous preblend and stirred vigorously at, approximately, 30 to 800C and preferably, 50 to 600C until a uniform, grease-like emulsion is formed. Small amount of formalin may be added once the product is uniform in order to prevent bacterial activity.Unlike many conventional silicone emulsions, neither colloid milling nor homogenization is required in order to prepare these emulsions, but these means may be utilized if desired.
The consistency of the emulsion can be controlled by the amount of water added. At a 1 5 to 20% water level, the emulsion has a greaselike consistency, but additional water will lower the viscocity of the system to a lotion-like consistency and even more water can be utilized in order to prepare a low viscosity emulsion. The silicone-water emulsions of the present invention are fully dispersible in water.
Additionally, the consistency of the formulation can be further modified by the quantity of the cyclic polysiloxanes added. In other words, the more cyclics-the thicker the emulsion and more grease-like it will be. A lower ratio of cyclic polysiloxanes will provide a thinner emulsion.
The emulsifiers themselves influence the constistency of the product. A solid emulsifier like polyoxyethylene 40 stearate will make the emulsion thicker and more grease-like while a more liquidous emulsifier will provide a lotion-like product.
As can be seen, a wide range of emulsion formulations can be achieved by varying any one of these process parameters: concentration of water, cyclic polysiloxane, or emulsifiers, and the type of emulsifiers, whether solid or liquid.
Example 1 To a 2 liter stainless steel beaker was added 200 grams water, 82 grams polyoxyethylene 40 stearate, and 67 grams sorbitan monostearate which are heated at 65 to 750C with stirring until a uniform mixture was achieved when all the solids had melted. Whereupon, 900 grams decamethylpentasiloxane was slowly added to the aqueous system and stirred vigorously at, approximately, 50 to 600C in order to form a uniform grease-like emulsion. Two grams of Formalin was added once the product had achieved uniformity, in order to prevent bacterial activity. The emulsion was formed without colloid milling nor homogenization and a stable stiff, paste-like emulsion was formed which was suitable for serving as a vehicle for applying an epidermal enhancing agent such as a deodorant or antiperspirant for application directly to the skin.
Example 2 The procedure of Example 1 was followed but was modified by the further addition of 11% by weight of polyoxyethylene 20 sorbitan monooleate whereupon an emulsion having the consistency of a lotion containing, approximately, 64% by weight of the pentasiloxane was obtained as was suitable for use in cosmetic products.
Example 3 Following the example of method 1, a wateremulsifier preblend consisting of 135 grams of polyoxyethylene 40 stearate and 100 grams sorbitan monostearate along with 300 grams of water was prepared. To this was added 1300 grams of decamethylpentasiloxane, which formed a grease-like emulsion. Formalin was added as an anti-bacterial agent.
Example 4 An emulsifier preblend consisting of 255 grams of water, 82 grams polyoxyethylene 40 stearate and 67 grams sorbitan monostearate was prepared in accordance with the method in Example 1, whereupon this preblend was added to 900 grams of octamethyltetrasiloxane in order to form a paste-like emulsion.
Example 5 An emulsion was formed from 50-50 cyclic silicone mixture consisting of 450 grams octamethyltetrasiloxane and 450 grams decamethylpentasiloxane, which was formulated with an emulsifier-water preblend consisting of 82 grams polyoxyethylene 40 stearate and 57 grams sorbitan monostearate and 280 grams water A silicone-water emulsion having a greaselike consistency was formed.
Example 6 To 900 grams of decamethylpentasiloxane was added a preblend consisting of 60 grams sorbitan monostearate and 200 grams of 70% octylphenoxypolyethoxy 39 ethanol and 200 grams water. Following the method described in Example 1 a silicone-water emulsion having soft paste-like consistency was formed.
Example 7 An antiperspirant was formed by combining 100 grams of the silicone-water emulsion paste of Example 4 with 20 grams aluminum chlorhydrate in the form of Micr-Dry Ultrafine (Trademark of Releis Co.).
Example 8 A skin freshener was formed by combining 100 grams df the silicone-water emulsion paste of Example 6 with 0.25% perfume.
Example 9 A suntan lotion was formed by combining 100 grams of the silicone-water emulsion lotion of Example 2 with 3.0% homosalate and 0.25% perfume.
