Claims
- 1. A particle stabilizing composition comprising:
a. an emulsion, comprising from about 1% to about 99%, by weight of the emulsion, of an internal phase and from about 1% to about 99%, by weight of the emulsion, of an external phase; b. a charged species that is present in the emulsion; and c. charged insoluble solid particles which are dispersed in said emulsion; wherein the charged species possesses a charge which is opposed to that of the charged insoluble solid particles and wherein essentially all of the charged species and charged insoluble solid particles accumulate at the interface of the emulsion and wherein Brownian motion is not exhibited by the charged insoluble solid particles.
- 2. The composition of claim 1 wherein the emulsion is selected from the group consisting of water-in-oil emulsions, oil-in-water emulsions, water-in-silicone, silicone-in-water, water-in-silicone elastomer emulsions, silicone elastomer-in-water emulsions and combinations thereof.
- 3. The composition of claim 1 wherein the charged species is selected from the group consisting of hydrogen ions, acids, bases, ionic polymers, ionic surfactants, lipids and mixtures thereof.
- 4. The composition of claim 1 wherein said composition further comprises from about 0.1% to about 25%, by weight of the composition, of an emulsifier.
- 5. The composition of claim 1 further comprising uncharged insoluble solid particles.
- 6. The composition of claim 1 wherein the composition comprises from about 5% to about 20%, by weight of the composition, of the charged insoluble solid particles.
- 7. The composition of claim 1 wherein said composition is in a product form selected from the group consisting of cosmetics, fabric care products, home care products, diapers, incontinence articles, feminine care products, pharmaceuticals, oral care products, antiperspirants, deodorants, personal cleansing products, skin care products, and hair care products.
- 8. The composition of claim 1 wherein said charged species is selected from the group consisting of a first polyanion and a first polycation.
- 9. A particle stabilizing composition comprising:
a. an emulsion comprising from about 1% to about 99%, by weight of the emulsion, of an internal phase and from about 1% to about 99%, by weight of the emulsion, of an external phase; b. a first charged species which is selected from the group consisting of a first polyanion and a first polycation wherein said first species is present in the emulsion; and c. charged insoluble solid particles that are dispersed in said emulsion in the presence of a second charged species which is selected from the group consisting of a second polyanion and a second polycation; wherein the first charged species possesses a charge opposed to that of the second charged species and of the charged insoluble solid particles and wherein essentially all of the charged species and charged insoluble solid particles accumulate at the interface of the emulsion and wherein Brownian motion is not exhibited by the insoluble solid particles.
- 10. The composition of claim 9 wherein the first polyanion is selected from the group consisting of ammonium polyacrylate, sodium polyacrylate, potassium polyacrylate, ethylene acrylic acid copolymer, hydrolyzed wheat protein polysiloxane copolymer, dimethicone copolyol phosphate, phosphate ester, sodium chondroiton sulfate, sodium hyaluronate, ammonium hyaluronate, sodium alginate, ammonium alginate, diglycol cyclohexanedimethanol isophthalates sulfoisophthalates copolymer and mixtures therof.
- 11. The composition of claim 9 wherein the first polycation is selected from the group consisting of chitosan, derivatives of chitosan, chitosan di-pyrrolidone carboxylate, hydroxypropyl chitosan, quaterniums, quaternium-80, quaternium-61, polyquaterniums, hydroxyethyl cetyldimonium phosphate, adipic acid/dimethylaminohydroxypropyl diethyltriamine copolymer, guar hydroxypropyltrimonium chloride, dimethicone copolyol amine(s), amidomethicones, dimethicone salts and mixtures thereof.
- 12. The composition of claim 9 wherein said composition is in a product form selected from the group consisting of cosmetics, fabric care products, home care products, diapers, incontinence articles, feminine care products, pharmaceuticals, oral care products, antiperspirants, deodorants, personal cleansing products, skin care products, and hair care products.
- 13. A method for providing natural appearance to the skin, said method comprising the step of topically applying the composition of claim 1 to the skin.
- 14. A method for minimizing fine lines and wrinkles and covering blemishes, said method comprising the step of topically applying the composition of claim 1 to the skin.
- 15. A method for cleaning or conditioning fabrics, said method comprising the step of applying the composition of claim 1 to fabrics in need of such treatment.
- 16. A method for preventing and/or treating skin irritations, said method comprising the step of topically applying the composition of claim 1 to the skin.
- 17. A method for cleaning or conditioning hair, said method comprising the step of applying the composition of claim 1 to hair in need of such treatment.
