Abstract
Official abstract text for this publication.
Heterocyclic compounds are provided. In particular, the heteroatom of the heterocyclic compound may be nitrogen. The heterocyclic compounds may demonstrate capacity of stabilizing photoactive compounds. Topical compositions comprising these heterocyclic compounds are also provided. In particular, these topical compositions further comprise photoactive compounds. Methods for stabilizing photoactive compounds are also provided. These methods comprise mixing the photoactive compounds with photostabilizing heterocyclic compounds.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heterocyclic compound selected from the group consisting of: and mixtures thereof. 2. A composition comprising at least one heterocyclic compound of claim 1 . 3. The composition of claim 2 , wherein the heterocyclic compound is present in amount ranging from 0.01 to 25% by weight of the total composition. 4. The composition of claim 2 , further comprising at least one photoactive compound. 5. The composition of claim 4 , wherein the photoactive compound is selected from the group consisting of a retinoid, a sunscreen, or mixture thereof. 6. The composition of claim 5 , wherein the photoactive compound is a retinoid. 7. The composition of claim 6 , wherein the retinoid is present in amount ranging from about 0.0001 to about 20% by weight of the total composition. 8. The composition of claim 5 , wherein the photoactive compound is a sunscreen. 9. The composition of claim 8 , wherein the sunscreen is selected from the group consisting of a UVA chemical sunscreen, a UVB chemical sunscreen, a physical sunscreen, and mixture thereof. 10. The composition of claim 9 , wherein the sunscreen is a UVA chemical sunscreen. 11. The composition of claim 10 , wherein the UVA chemical sunscreen is present in amount ranging from about 0.001 to about 20% by weight of the total composition. 12. The composition of claim 9 , wherein the sunscreen is a UVB chemical sunscreen. 13. The composition of claim 12 , wherein the UVB chemical sunscreen is present in amount ranging from about 0.001 to about 45% by weight of the total composition. 14. The composition of claim 4 , further comprising at least one ingredient selected from the group consisting of oils, surfactants, humectants, botanical extracts, particulate materials, antioxidants, and other vitamins.
