The fragrance compositions can include at least one fragrance compound and a glycoside. The glycoside can be selected from a Steviol glycoside, a glucosylated Steviol glycoside, a derivative of a Steviol glycoside, a derivative of a glucosylated Steviol glycoside, or combinations thereof. Also provided for are products including a long-lasting fragrance composition as above. The products can include perfumes, body care products, cosmetics, cleaning and laundry products, and the like. ## Claims ### Claim 1 A fragrance composition for a non-comestible product comprising: at least one fragrance compound; and a glycoside selected from a Steviol glycoside, a glucosylated Steviol glycoside, a derivative of a Steviol glycoside, a derivative of a glucosylated Steviol glycoside, or combinations thereof; wherein the glycoside is a fragrance fixative such that by inclusion of the glycoside: a perceived duration of fragrance is increased by addition of the glycoside, or a perceived strength of the fragrance compound is undiminished when reduced by about 1% to 2%. ### Claim 2 (depends on 1) The fragrance composition of claim 1, further comprising a solvent, wherein the solvent is selected from alcohol, hydroalcohol, water, propylene glycol, or a combination thereof. ### Claim 3 (depends on 1) The fragrance composition of claim 1, wherein the glycoside comprises from about 0.001 to 0.5 weight % based on a total weight of the fragrance composition. ### Claim 4 (depends on 1) The fragrance composition of claim 1 wherein the glycoside is a Steviol glycoside selected from Rebaudioside A, Rebaudioside B, Rebaudioside C, Rebaudioside D, Rebaudioside E, Rebaudioside F, Rebaudioside M, Rebaudioside N, Rebaudioside O. ### Claim 5 (depends on 1) The fragrance composition of claim 1, wherein the Steviol glycoside is enzymatically treated stevia extract. ### Claim 6 (depends on 1) The fragrance composition of claim 1, wherein the glucosylated Steviol glycoside has a low degree of glycosylation, where the number of glucose molecules attached to the steviol glycoside is from one to five. ### Claim 7 (depends on 1) The fragrance composition of claim 1, wherein the glucosylated Steviol glycoside has a high degree of glycosylation where the number of glucose molecules attached to the steviol glycoside is from six to ten. ### Claim 8 A non-comestible product including a fragrance composition, the fragrance composition comprising at least one fragrance compound; and a glycoside selected from a Steviol glycoside, a glucosylated Steviol glycoside, a derivative of a Steviol glycoside, a derivative of a glucosylated Steviol glycoside, or combinations thereof; wherein the glycoside is a fragrance fixative such that by inclusion of the glycoside: a perceived duration of fragrance is increased by addition of the glycoside, or a perceived strength of the fragrance compound is undiminished when reduced by about 1% to 2%. ### Claim 9 (depends on 8) The product of claim 8, wherein the product is selected from a perfume, a toilet water, a lotion, a soap, a cosmetic, or a body care product. ### Claim 10 (depends on 8) The product of claim 8, wherein the product is selected from a dishwashing detergent, a surface cleaner, an air freshener, a softener, a bleach, or a laundry detergent. ### Claim 11 (depends on 8) The product of claim 8, further comprising a solvent, wherein the solvent is selected from alcohol, hydroalcohol, water, propylene glycol, or a combination thereof. ### Claim 12 (depends on 8) The product of claim 8, wherein the glycoside comprises from about 0.001 to 0.5 weight % based on a total weight of the fragrance composition. ### Claim 13 (depends on 8) The product of claim 8, wherein the glycoside is a Steviol glycoside selected from Rebaudioside A, Rebaudioside B, Rebaudioside C, Rebaudioside D, Rebaudioside E, Rebaudioside F, Rebaudioside M, Rebaudioside N, Rebaudioside O. ### Claim 14 (depends on 8) The product of claim 8, wherein the Steviol glycoside is enzymatically treated stevia extract. ### Claim 15 (depends on 8) The product of claim 8, wherein the glucosylated Steviol glycoside has a low degree of glycosylation, where the number of glucose molecules attached to the steviol glycoside is from one to five. ### Claim 16 (depends on 8) The product of claim 8, wherein the glucosylated Steviol glycoside has a high degree of glycosylation where the number of glucose molecules attached to the steviol glycoside is from six to ten. ### Claim 17 A non-comestible product comprising a perfume, the perfume comprising water, ethanol, a glycoside, and a fragrance compound; wherein the glycoside is a fragrance fixative. ### Claim 18 (depends on 17) The non-comestible product of claim 17, wherein the glycoside is selected from a Steviol glycoside, a glucosylated Steviol glycoside, a derivative of a Steviol glycoside, a derivative of a glucosylated Steviol glycoside, or combinations thereof. ### Claim 19 (depends on 17) The non-comestible product of claim 17, further comprising alcohol, hydroalcohol, water, propylene glycol, or a combination thereof. ### Claim 20 (depends on 17) The non-comestible product of claim 17, wherein the glycoside comprises from about 0.001 to 0.5 weight % based on a total weight of the fragrance composition.
