Claims
- 1. A food-grade lipstick, face cream, face base, toothpaste, mouth wash or other pharmaceutical carrier or cosmetic composition comprising a food-grade material and from 0.01% to 25% of a modifier consisting essentially of a non-proteinaceous colloidal precipitate of whey, and wherein said whey colloidal precipitate is the product of a process having at least one step of (a) raising the pH of whey to at least 5.0 ,and (b) heating the whey to a temperature of at least 80.degree. C. for a time sufficient to produce said precipitate, and the precipitate of that said process being identifiable as a complex precipitate which in aqueous suspension has an average particle size of less than 10 microns, is essentially white in color, exhibits no disagreeable taste in aqueous suspensions of up to about 30%, can be dried to a free-flowing powder, is capable of gelling water and petroleum ether, said whey being priorly sufficiently de-proteinated so that 5% by weight of trichloroacetic acid therein will not yield more than 5% by weight of precipitated protein.
- 2. The composition of claim 1 wherein said composition is an emulsion, suspension, or gel.
- 3. The composition of claim 1 wherein said composition is an aqueous suspension and said composition contains a suspension stabilizing amount of the whey colloidal precipitate.
- 4. The composition of claim 1 wherein said composition is an emulsion and the composition contains an emulsifying amount of the whey colloidal precipitate.
- 5. The composition of claim 1 wherein said composition is an aqueous gel and the composition contains a gelling amount of the whey colloidal precipitate.
- 6. The composition of claim 4 wherein the emulsion contains an oil or fat.
- 7. The composition of claim 1 wherein said composition is a clouded suspension or a clouded solution.
- 8. The composition of claim 1 wherein the whey colloidal precipitate is substantially neutralized.
- 9. The composition of claim 1 in a dried form.
- 10. The composition of claim 1 wherein the pH of the precipitate is between 5.0 and 8.5.
- 11. The composition of claim 10 wherein the pH is between 6.5 and 7.8.
- 12. The composition of claim 1 wherein the amount of modifier is between 0.5% and 25%.
- 13. The composition of claim 1 wherein the amount of modifier is between 1% and 25%.
- 14. The composition of claim 1 wherein the amount of modifier is between 15% and 25%.
- 15. The composition of claim 1 wherein the whey colloidal precipitate is derived from clarified whey.
- 16. The composition of claim 1 wherein the whey colloidal precipitate is derived from ultrafiltered whey permeats.
- 17. The composition of claim 1 wherein the composition also contains a non-toxic divalent cation selected from calcium and phosphorus in amounts wherein the properties of the whey colloidal precipitate for stabilization of aqueous suspensions are enhanced.
- 18. The composition of claim 1 wherein the composition is a pharmaceutical carrier.
- 19. The composition of claim 1 wherein the composition is a cosmetic.
- 20. The composition of claim 19 wherein the composition is a lipstick.
- 21. The composition of claim 19 wherein the composition is a face cream.
- 22. The composition of claim 19 wherein the composition is a face base.
- 23. The composition of claim 1 wherein the composition is a toothpaste.
- 24. The composition of claim 1 wherein the composition is a mouthwash.
