Stable tooth whitening gum with reactive ingredients
View Patent ↗Oral compositions including an encapsulated active component(s) are provided. The oral compositions include a carrier composition including a first reactive component. The oral compositions also include an active composition. The active composition includes at least one active component encapsulated in a coating. The coating includes a hydrophilic material and at least one second reactive component, wherein an interaction between the first and second reactive components preserves the activity and/or availability of the active.
1. An oral composition having an increased shelf life comprising:
(a) a carrier composition comprising at least one first reactive component, wherein the carrier composition is selected from the group consisting of a gum base, a confectionary base, a toothpaste base, a gel dentifrice base and a tooth powder base; and
(b) an active composition comprising at least one active component encapsulated in a coating, wherein said at least one active component comprises a peroxide, said coating comprising:
(i) a physical barrier coating comprising gum arabic; and
(ii) a reactive barrier coating comprising gum arabic and one or more phosphate salt,
wherein the first reactive component is selected from the group consisting of acids, flavors, lecithin, peroxides, fluorides, water, aldehydes and glycerin; and
wherein said coating provides an interaction of the first reactive component and the one or more phosphate salt, wherein said interaction prevents a degradation of the peroxide by controlling the pH of the first reactive component and provides an increased shelf life of the oral composition of at least one year as measured by the presence of at least 75% of the peroxide remaining, or,
the interaction of the first reactive component and the one or more phosphate salt provides an increased shelf-life of the oral composition of at least six months as measured by the presence of at least 90% of the peroxide remaining.
2. The oral composition of claim 1 , wherein the increased shelf-life of the oral composition is maintained for at least one year as measured by the presence of at least 75% of the active remaining.
3. The oral composition of claim 1 , wherein the increased shelf-life of the oral composition is maintained for at least six months as measured by the presence of at least 90% of the active remaining.
4. The oral composition of claim 1 , wherein the first reactive component is an acid.
5. The oral composition of claim 1 , wherein the first reactive component is selected from the group consisting of flavorants, aldehydes and glycerin.
6. The oral composition of claim 1 , wherein the composition is a gum composition.
7. The oral composition of claim 1 , wherein the composition is a lozenge composition.
8. The oral composition of claim 1 , wherein the composition is a mint composition.
9. The oral composition of claim 1 , wherein the composition is a candy composition.
10. The oral composition of claim 1 , wherein the composition is a toothpaste composition.
11. The oral composition of claim 1 , wherein the composition is a gel dentifrice composition.
12. The oral composition of claim 1 , wherein the composition is mouthrinse or mouthwash composition.
13. The oral composition of claim 1 , wherein the composition is a tooth powder composition.
14. A tooth whitening gum composition having an increased shelf life comprising:
(a) a gum base, said gum base comprising at least one first reactive component, which upon exposure to one or more active components, reacts therewith to reduce the activity of one or more active components; and
(b) an active composition comprising at least one active component, wherein said at least one active component comprises a peroxide, encapsulated in a coating, said coating comprising:
(i) a physical barrier coating comprising gum arabic; and
(ii) a reactive barrier coating comprising gum arabic and one or more phosphate salt,
wherein the first reactive component is selected from the group consisting of acids, flavors, lecithin, peroxides, fluorides, water, aldehydes and glycerin; and
wherein said coating provides an interaction of the first reactive component and the one or more phosphate salt,
wherein said interaction provides an increased shelf life of the tooth whitening gum composition of at least one year as measured by the presence of at least 75% of the peroxide remaining, or,
provide a shelf-life of the tooth whitening gum composition of at least six months as measured by the presence of at least 90% of the peroxide remaining.
15. A tooth whitening gum composition having an increased shelf life comprising:
(a) a gum base, said gum base comprising at least one first reactive component, which upon exposure to one or more active components, reacts therewith to reduce the activity of one or more active components; and
(b) an active composition comprising at least one active component wherein said at least one active component comprises a peroxide, and wherein said active composition is encapsulated in a coating, said coating comprising:
(i) a physical barrier coating comprising gum arabic; and
(ii) a reactive barrier coating comprising gum arabic and one or more phosphate salt,
wherein said first reactive component is selected from the group consisting of acids, flavors, lecithin, peroxides, fluorides, water, aldehydes and glycerin;
wherein said coating provides an interaction of the first reactive component and the one or more phosphate salt,
wherein said interaction provides an increased shelf life of the tooth whitening gum composition of at least one year as measured by the presence of at least 75% of the peroxide remaining, or,
provide a shelf-life of the tooth whitening gum composition of at least six months as measured by the presence of at least 90% of the peroxide remaining.
