Definitions

  • the present invention relates to body care compositions of matter such as moisturizers, lotions, creams, shampoos, hair conditioning, coloring, body building, and perming agents, and to body care methods utilizing such compositions.
  • the cuticle is composed of a layer of flattened, horny scales made up of keratinized protein. These scales overlap and move over one another to provide a flexible protection, like an armor covering of the hair shaft.
  • Current technology requires use of an alkaline substance which hydrolyzes the scales, which causes them to swell and raise from the hair shaft. Normal procedure then utilizes an acid rinse to stop the alkaline hydrolysis process.
  • the cortex portion of the hair shaft is made up of intertwined molecules of keratin protein.
  • the central portion of the hair fiber is known as the medulla and is composed of soft keratin.
  • the cortex is probably the most important portion of the hair structure as it relates to coloring or perming of the hair.
  • Perming is a two step process. Step one uses an alkaline solution to break the disulfide bonds in the hair cuticle and step two rejoins them in a new position. Different perm formulas break disulfide bonds in different ways. In cold waves, the reforming lotion does the work. In heat activated perms, heat and tension are required in addition to the reforming lotion. In both cases, the reduction process softens the protein and allows it to assume the shape of the curler. The final step in every perm is to saturate the hair with a chemical oxidizing agent, called a neutralizer. Again, the alkaline used to break the disulfide bonds can do significant damage to the hair.
  • a chemical oxidizing agent called a neutralizer.
  • an aqueous composition containing small quantities of an inorganic colloidal silica greatly enhances the penetration of water, oils, and collagen into the epidermis of aging dehydrated skin. It also enhances the penetration of water, oils, and collagen into hair shafts. With enhanced penetration into the hair, hair coloring material penetrates the hair shafts to provide brighter color and longer retention of the color in the hair, and water or perming compositions penetrate into the hair shafts, all without use of alkaline chemicals which can damage the hair, and which are required in the prior art.
  • the colloidal silica composition can be neutral or weakly acidic so as not to cause damage to the hair.
  • the inorganic colloidal silica can be beneficially used in a wide variety of body care compositions such as in shampoos, conditioners, styling gels, styling mists, hair coloring preparations, hair perming compositions, body lotions, face creams, skin creams, bath additives, pedicure and manicure applications, hand lotions, lip balms, lipsticks, suntan lotions, and sunscreen lotions.
  • body care compositions such as in shampoos, conditioners, styling gels, styling mists, hair coloring preparations, hair perming compositions, body lotions, face creams, skin creams, bath additives, pedicure and manicure applications, hand lotions, lip balms, lipsticks, suntan lotions, and sunscreen lotions.
  • the use of the inorganic colloidal silica in facial cleansers, moisturizing creams, and facial mists provide a package for improvement of skin moisture, tone, and youthful appearance.
  • hair perming compositions the composition will allow water to penetrate into the hair shafts causing them to swell
  • the active component of the invention comprises an aqueous suspension of a colloidal silicon dioxide, preferably an aqueous solution with silica suspended therein.
  • the silicon dioxide particles are preferably from about 10 to about 100 angstroms in size and have an electrical charge thereon.
  • the solution is preferably mixed in such a way that the colloidal particles become electrically charged, preferably by circulation of the solution through a magnetic field, and further, that the solution pass through a magnetic void during mixing so that the charged particles assume a stable configuration in relation to internal bonding.
  • the charge on the colloidal particles is stabilized to remain during a relatively long shelf life of the final product by the mixing process and by the addition of molar amounts of citrate or citrate salts.
  • the colloidal particles are also believed to carry several layers of water bound to the particle.
  • the invention comprises a hydration-enhancing composition of matter containing a unique blend of an inorganic colloidal silica in combination with a usual body care composition or hair coloring agent.
  • the final body care or hair coloring compositions of the invention preferably contain colloidal silica in a concentration from about 1 part per million [ppm] to about 50 parts per million [ppm] .
  • greater concentrations of colloidal silica are also equally effective, and lesser concentrations may be effective in many applications.
  • an aqueous suspension of colloidal silica is used in perming the hair.
  • the hair is rolled tightly on rollers or other forms and the solution of the invention is applied thereto. This causes the hair to swell and break the disulfide bonds therein. These bonds are reestablished upon drying of the hair on the rollers or other forms so the hair takes the new form as with prior art chemical perms.
  • the aqueous colloidal silica solution of the invention is a potent conductor of charge. When applied to the hair it varies the normal electrostatic fields on the hair shafts and allows current flow on the hair cortex and the hair surface. It is believed that this manipulation of the normal electrostatic field of the hair and the current flow helps in the effectiveness of the hair perming and hair coloring processes.
  • the invention also includes the method of applying an aqueous solution of colloidal silica as part of a body care, hair coloring, or hair perming procedure.
  • FIG. 1 is a representation of the structure of the human epidermis or skin
  • Fig. 2 a schematic representation of the believed polymerization behavior of silica
  • Fig. 3 is a perspective view of a mixing apparatus useful for making colloidal silica solutions according to the invention.
  • Fig. 4 a vertical section taken on the line 2-2 through the center of the mixing apparatus of Fig. 1, but with some parts shown in elevation.
  • Enhanced body care compositions or products can be formulated by adding an aqueous suspension of colloidal silica to an existing body care product such as a skin cream, body lotion, shampoo, hair conditioner, cleanser, hair coloring solution, hair permanent solution, etc. to bring the concentration of colloidal silica within the body care product to a preferred range of from about 1 ppm to about 50 ppm.
  • the body care product is then used in a normal manner, but it has been found that such product is more effective than the product without the colloidal silica added thereto.
  • the presence of the colloidal silica in the product appears to dramatically increase the ability of the product to penetrate into body parts.
  • the product and the water, oils, and collagen therein, if present, will actually penetrate into the epidermis, into the hair, or into the nails of a user so that the product can replace components lost from those body parts and moisturize such body parts.
  • the result with skin care products is substantially more hydration or moisturization of the skin to keep its natural tone and consistency and reduce wrinkling, with hair care products to decrease drying and maintain body and manageability, with hair coloring products to provide deeper and more lasting color since the color components better penetrate the hair itself, with both hair coloring and hair perming products to allow effective coloring or perming of the hair without damaging the hair through use of alkaline solutions, and with the nails, better moisturization to provide better flexibility and strength.
  • colloidal silica allows the oil and collagen in the product to penetrate the superficial layers of the epidermis rather than merely sit on the surface of the epidermis, and allows the water in the product to penetrate more deeply into the deeper layers of the epidermis.
  • Fig. 1 is a representation of the structure of the skin.
  • the stratum corneum and stratum lucidum form the outer or superficial layers of the skin.
  • the presence of the colloidal silica particles of the invention in an oil or collagen containing composition aid in allowing the oils and collagen to penetrate the superficial layers of the skin.
  • the oils and collagen will better penetrate the stratum corneum and stratum lucidum.
  • the oils and/or collagen in the superficial layers of the skin will tend to hold moisture in the skin and retard the drying of the skin.
  • the presence of the colloidal silica particles of the invention in a water-containing composition aid in allowing the water to penetrate deeply into the skin, probably all the way to the stratum basale and basement membrane. Such penetration of water into the skin moisturizes or hydrates the skin to combat skin drying by replacing water otherwise lost from the skin.
  • the aqueous suspension of colloidal silica preferably takes the form of a solution to be added in small amounts to body care compositions or used as part of the hair coloring or perming process and is preferably prepared in such a way that the colloidal particles become charged (it is believed that the particles take on a net negative charge) and assume an active configuration and the charge and configuration is stabilized so that the particles remain charged and remain in suspension during a relatively long shelf life of the solution and a relatively long shelf life of any products made using the solution.
  • the particles and solution may be stabilized by adding citric acid (tripotassiu salt) to the solution containing the particles and pH adjusted with acetic acid so it will also contain traces of citrate and acetate.
  • the solution contains about 500 PPM colloidal silica, 0.001 moles/liter of potassium citrate, and traces of acetate, in purified distilled water.
  • This aqueous solution may be added in very small amounts to body care compositions to aid penetration of moisture or oils into epidermal structures such as skin, hair, and nails, or diluted and used as a solution itself in perming procedures.
  • an aqueous solution of colloidal silicon dioxide is first made up. This can be done by starting with a solution that is about 27% silicon dioxide in 3-4 molar NaOH. As one option, it has been found that citric acid or citric acid salts added in molar amounts about equal to the molarity of the NaOH improve the stability of the end solution.
  • the starting solution and citric acid or citric acid salts, if present, is diluted very slowly, with stirring. Preferably, this is done over a period of several hours.
  • the solution is very slowly titrated with about 0.5-1.0 molar of an acid, usually hydrochloric or acetic acid, to a pH of between about 7.6 and 8.2.
  • the final concentration is a solution of preferably about 0.050% (about 500 parts per million) colloidal silica. At this time the silica is present as colloidal particles of between about 10 to 100 angstroms in size.
  • Fig. 2 is a diagram from The Chemistry of Silica: Solubility, Polymerization, Colloid and Surface Properties, and Biochemistry, by Ralph K. Her, published 1979 by Wiley, representing schematically the believed polymerization behavior of silica.
  • silica particles in sol grow in size with decrease in numbers.
  • silica particles aggregate into three-dimensional networks and form gels.
  • Neither the enlarged sols nor the silica gels are satisfactory for the invention.
  • the growth of the sols or the formation of a gel has to be inhibited.
  • silica solution of the invention As the pH is lowered, polymerization of monomer occurs to form particles, i.e. , Si(OH) 4 condenses to form colloidal particles. The condensation forms Si-O-Si links. This is believed to lead to a highly porous, tangled network of branching chains as shown by reference numbers 8 and 9 in Fig. 2. These structures appear to accept electrical charge. These particles grow with the lowering of the pH as indicated by arrow A. The solution is inhibited from becoming a gel by the addition of citrate and by generating like charges on the particles which cause the particles to repel one another. Thus, the growth of the particles is stopped after the particles have grown to a size of between about 10 angstroms and 100 angstroms and with structures as shown at 8 and 9.
  • the solution be circulated through a magnetic field so that movement of the silica particles through the magnetic field generates the electrical charge on the silica particles.
  • Silicon dioxide is a semi-conductor material. If the silica particles are passed through a magnetic field so as to cut through the lines of flux of the field, an electrical charge is generated on the particles as they cut through the lines of flux.
  • the particles act as both a conductor and a capacitor, i.e., they generate a charge and store the charge. After passing through a magnetic field to generate a charge on the silica particles, it is preferred that the particles be passed through a space substantially void of any magnetic fields.
  • a mixing chamber 10 is supported above base 11 by supporting legs 12, secured to mixing chamber 10 as by screws 13.
  • a platform 14 is mounted to the tops of legs 12 and extends over mixing chamber 10 to support a motor 15.
  • a shaft 16 extends from motor 15 to support a mixing blade 17, Fig. 4, in mixing chamber 10.
  • the lower portion 10a of mixing chamber 10 is of conical formation.
  • the mixing chamber and the supporting legs are preferably made of a nonferrous material.
  • Nonferrous tubing 20 extends from the vortex of the lower conical portion 10a of mixing chamber 10 to the top of the conical portion where it is wrapped into a helical coil, indicated generally as 21, around the conical portion 10a of mixing chamber 10. From the bottom of helical coil 21, tubing 20 extends through an opening 22 in platform 23 supported above base 11 and below mixing chamber 10 by legs 24, and to pump 25. From pump 25, tubing 26 extends to a tee fitting 27, and tubing 28 continues from the tee fitting to the top of mixing chamber 10. A valve 29 is positioned in the base of tee 27 and controls flow into tubing 30 extending from the base of tee 27. Motor 15 and pump 25 are both electrically powered so have electrical wires 31 and 32, respectively, extending therefrom.
  • Electromagnets 34, 35, 36, and 37 are securely mounted in platform 23 such as by being received in recesses therein as shown by broken lines in Fig. 4.
  • Magnets 34, 35, 36, and 37 are arranged so that the poles of the magnets are in a single plane and form the vertices of a quadrilateral shape in that plane.
  • quadrilateral shape is a square as for the arrangement illustrated.
  • the poles of adjacent magnets are of opposite orientation such as indicated by the "+" and "-" signs in Fig. 3.
  • the two positive poles shown as magnets 34 and 36
  • the two negative poles shown as magnets 35 and 37
  • Each of the magnetic poles is magnetically attracted by the two oppositely charged, adjacent poles and repelled by the opposite like charged pole.
  • the four magnets exert a sphere of magnetic influence on one another and create a magnetic field which extends above the magnets, i.e., mostly above the plane containing the poles of the magnets, to encompass the helical coil 21. This provides the magnetic field through which the solution flows during mixing. As the colloidial particles flow through the helical coil 21, they cut through the lines of magnetic flux of the magnetic field.
  • the four electromagnets 34, 35, 36, and 37 be identical, except for their pole orientation, and that they each produce approximately equal magnetic flux. Electromagnets which create about 2000 to 3000 gauss each have been found satisfactory, and in such instances, each magnet should produce equal flux within plus or minus 200 gauss, i.e. the gauss produced by such magnets should all be equal within a range of about 400 gauss. Also, the magnetic flux for each magnet should be centered in each pole.
  • the electromagnets are powered by a D.C. power supply 38 with wires 39 connecting the power supply to the magnets in standard fashion. A wire 40 extends from D.C.
  • a source of electrical power such as a source of standard 120 volt AC power, not shown. It may be necessary to cool the electromagnets. Such cooling may be accomplished in normal manner by circulating a cooling fluid, such as cold water, through a cooling jacket, not shown, surrounding the electromagnets or surrounding the heads of the electromagnets. Also, while electromagnets are shown and currently preferred, permanent magnets may be used. In order to obtain the desired high magnetic field for large mixing equipment, exotic permanent magnets such as neodymium magnets would preferably be used. To prepare the colloidal suspension of the invention using the apparatus shown and described, mixing chamber 10 is filled with purified water.
  • the use of purified water is presently preferred since it is believed that the water penetrates deeply into the epidermis.
  • the water is purified by series filtering through various filter beds depending upon the impurities in the starting water, by then heat distilling the water, aerating it, and then passing it through an ultraviolet light chamber. It has been found that for most public water supplies, the water should be first chlorinated to 3 PPM and aerated, then passed through a CaMgC0 3 (crushed marble) filter, a +35-20 mesh clinoptilolite filter, a particulate filter, and a -20+35 mesh activated carbon filter, before aeration and ultraviolet sterilization.
  • CaMgC0 3 crushed marble
  • the purified water is circulated by pump 25 from mixing chamber 10, through the helical coil 21 and the magnetic field generated by electromagnets 34, 35, 36 and 37, through the magnetic void between the magnets, and back into mixing chamber 10 on a continuous basis for about 30 minutes.
  • a silica concentrate comprising 27% silicon dioxide in 3 molar NaOH is then added to the circulating purified water. This mixture is circulated through the helix and magnetic field for about four hours. During this four hours of circulation, equal molar concentrations of citric acid in the form of tripotassium salt is slowly added to the solution. After circulation for about four hours with the slow addition of tripotassium salt, the pH of the solution is adjusted to pH 7.68 with acetic acid (1 molar) .
  • the adjusted solution is then circulated for an additional two hours.
  • the resulting solution is then diluted with purified water to a final desired concentration for addition to the body care products, usually to a concentration of 50 PPM or greater, preferably to a concentration of about 500 PPM. Circulation through the helix and the magnetic void is continuous during the whole procedure.
  • the silica solution is removed from the apparatus by opening valve 29 in tee 27 to allow the finished solution to flow through tubing 30 to storage, packaging, or the next stage of mixing.
  • the helical coil 21 be oriented so that the mixture travels during circulation therethrough in the direction it would normally circulate when draining from a basin, that is, counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
  • Example I One cc of a colloidal silica solution of the invention with a silica concentration of 500 PPM was added to 100 ccs of Vaseline Intensive Care Lotion®. After the addition of the silica solution, it was noted that the lotion showed increased absorption into the skin, estimated as a ten-fold increase in absorption, and was more effective in moisturizing the skin.
  • One cc of a colloidal silica solution of the invention with a silica concentration of 500 PPM was added to 100 cc of Prell® shampoo. Hair washed with the shampoo with the colloidal silica resulted in hair having a fuller and softer feeling and more manageable than hair washed in the shampoo without the colloidal silica. The shampoo itself was more viscous with the silica solution added and produced thicker lather during use.
  • a cleansing primer can be used to remove skin oils and/or make-up prior to the application of a hydrating mist.
  • a preferred cleansing primer contains the following body care components listed as percentages by weight:
  • the face feels cleaner than when using other face cleaners or soaps and feels cooler and smoother.
  • a hydrating misting agent comprises an aqueous suspension of the invention of colloidal silica in a preferred concentration range of about 50 ppm, optionally, collagen in a concentration of about 43 ppm, and 0.25% sodium hydroxymethyl glycinate.
  • a hydrating mist is used by spraying it on the face and neck.
  • a mask of facial tissue or thin collagen fibers may then be applied along with additional hydrating mist to keep it very moist for about twenty minutes.
  • the water from the mist penetrates the skin, i.e., the epidermal cells and interstitial spaces, and the face feels firmer and the tiny surface lines diminish.
  • use of the misting agent and facial mask of the invention results in a reduction of wrinkles and a face with a more youthful glow and feel.
  • a body care composition in this instance a surface active cream, contains the following body care components (all percentages are by weight): 58.39% water, 12.81% isopropyl myrestate, 8.44% mineral oil, 4.00% glycerine, 3.84% sorbitan stearate, 2.00% cocoa butter, 1.43% beeswax, 1.20% stearic acid, 1.20% cetyl alcohol, 1.12% polysorbate 60, 1.00% aloe vera oil, .99% glyceryl stearate S.E., 1.00% dimethicone, .75% triethanolamine, .30% sodium borate, .25% panthanol, .15% fragrance, .15% propylparaben, .15% methylparaben, .83% of an aqueous suspension of the invention of 500 ppm colloidal silica, and 0.25% sodium hydroxymethyl glycinate.
  • the colloidal silica is present in a final concentration of about 4.15 parts per million [ppm] .
  • Use of the surface active cream of the invention results in a smoother and softer feeling skin that maintains that feeling and look longer than with use of prior art creams and lotions and, importantly, the cream of the invention does not leave the oily and greasy feeling of the prior art creams and lotions.
  • the silica solution of the invention can be mixed with the dye components and that the dye components are then absorbed through the hair cuticle into the hair similarly as if the hair had been first treated with the usual alkaline solution.
  • an oxidizer usually a peroxide solution, such as a weakly acidic or neutral hydrogen peroxide solution, which causes oxidation of the dye components in the normal manner. Since an alkaline solution has not been used, the acid rinse or conditioning to stop the action of the alkaline solution is not necessary, however a rinse or conditioning will usually be performed after use of the oxidizing solution.
  • All biological organisms are permanently located in an atmospheric electrostatic field that varies according to atmospheric conditions (between 100-1000 V/M) .
  • the hair can pick up charge and generate its own electric field.
  • the anatomy of the hair is very similar to a lightening rod (sharp tip) , it enables the charged shaft of hair to generate a high electric field.
  • the tip of the hair shaft carries a positive charge while the portion of the hair shaft near the scalp carries a negative charge. Due to the high resistance of normal skin and hair, no compensating charge is supplied to the hair through the skin. This means that hair can stay charged for extended periods of time.
  • the colloidal silica solution of the invention provides a hydrophilic, charged, and highly conductive medium, and allows constant current flow in the hair. This postulated current flow in the hair may ultimately explain operation of the invention.
  • the colloidal silica solution provides highly charged conductive material in the form of the charged silica particles which adhere to the hair shaft and carry color into the shaft.
  • the highly charged solution neutralizes the charge on the hair shaft by allowing electrostatic discharge.
  • the discharge of the electrostatic charge allows this shell of hydration to be taken into the hair shaft without damaging the hair, most likely by iontophoresis. It will also carry with it the hair color, which, when in the hair, can then be oxidized in the same fashion as current technology provides.
  • the hair In the perming of hair, i.e., causing substantially permanent changes in the structure of the hair, it has been found that if the hair is secured to a form, such as a curler, and is then treated with the aqueous silica solution of the invention, the hair will absorb large amounts of water without chemical damage. The absorption of water causes the hair to swell. In swelling, the disulfide bonds are broken due to tension on the bonds. The hair is then dried which reestablishes the disulfide bonds, but the bonds are rearranged from when they were broken so that the hair substantially permanently takes on the configuration of the form, e.g. , the curl of the curler.
  • hair is tightly wrapped on a roller. It is then treated with a solution of 0.01m acetic acid, collagen and colloidal silica in a concentration of 50 ppm. The hair is dried with a conventional h air drier to repair the bonding linkage. If desired, stabilizers may also be used along with drying to repair the bonding linkage.
  • the results of perming in this manner appear to be comparable to the currently used chemical perming processes. However, since there is no chemical damage to the hair, repeated per anents can be given without accumulating trauma to the hair.
  • colloidal silica solution of the invention various hair coloring and hair perming and curling processes can be used.
  • the invention provides a method of increasing the absorption of water or water with other materials, such as dye components, into hair by applying an aqueous solution or suspension of charged colloidal silica particles along with the other material to be absorbed into the hair.
  • the aqueous suspension of charged colloidal silica particles provides the water.
  • the material may be included as part of the aqueous suspension, or the aqueous suspension may be added to the material, and then applied to the hair, or the aqueous suspension of silica particles may be applied to the hair either before or after application of the other material so that it mixes on the hair.

Abstract

On améliore l'efficacité et/ou le pouvoir hydratant de compositions de soin corporel telles que les lotions hydratantes, les crèmes pour la peau, les lotions pour le corps, les shampoings, les après-shampoings, les gels coiffants, les produits fixatifs, les colorants capillaires, les compositions de permanente, les additifs de bain, les produits de pédicure et de manucure, les démaquillants pour le visage, les brouillards faciaux, les lotions solaires et antisolaires, par l'addition d'une suspension aqueuse contenant des faibles concentrations de particules de silice colloïdale chargées présentant une masse comprise, de préférence, entre 10 et 100 angstroms. Pour ce qui concerne les produits de soins pour la peau, les composants hydratants sont mieux absorbés dans la structure épidermique du corps. Dans la coloration des cheveux, les composants colorants sont absorbés dans les cheveux, et dans les permanentes, les liaisons de bisulfure dans les cheveux peuvent être rompues par la tension due au gonflement résultant de l'absorption de l'eau par les cheveux, sans qu'il soit necéssaire d'utiliser des solutions alcalines agressives.
