Abstract
A cosmetic composition and a method of preparing a cosmetic composition that includes mangiferin characterized as demonstrating soluble and chemically stable mangiferin, wherein stability includes resistance to crystallization of mangiferin that is independent of temperature and pH.
Claims20
A cosmetic composition comprising:
- a. mangiferin;
- b. at least one of:
- at least one hydrotrope and at least one cyclodextrin;
- c. at least one polymeric precipitation inhibitor;
- and
- d. solvent,
- wherein the cosmetic composition is stable at any pH.

An aqueous cosmetic composition comprising:
- a. from about 0.01 to about 5.0 weight percent of mangiferin;
- b. one or more of:
- from about 0.01 to about 25 weight percent of at least one hydrotrope comprising caffeine, vitamin B3 and combinations thereof;
- and from about from about 0.01 to about 10 weight percent of at least one cyclodextrin comprising alpha-cyclodextrin, beta-cycl odextrin, gamma-cyclodextrin, hydroxypropyl-beta-cyclodextrin, hydroxypropyl-gamma-cyclodextrin, other cyclodextrin derivatives and combinations thereof.
- c. from about 0.01 to about 25 weight percent of at least one polymeric precipitation inhibitor;
- and
- d. from about 0 to about 90 weight percent of solvent, wherein the cosmetic composition is stable at any pH.
4 more elements
A method of preparing a cosmetic composition comprising:
- a. providing an isolate or extract comprising mangiferin up to 100% in purity mangiferin;
- b. mixing the mangiferin, at least one hydrotrope and at least one solvent to form a mixture;
- c. adding at least one polymeric precipitation inhibitor to mangiferin, hydrotrope and solvent mixture;
- and
- d. optionally adding at least one cyclodextrin to the mixture.
2 more elements
A method of preparing a cosmetic composition comprising:
- a. providing an isolate or extract comprising mangiferin up to 100% in purity mangiferin;
- b. mixing the mangiferin, and at least one solvent to form a mixture;
