Abstract
Abstract Water-soluble menthol glycosides are prepared by condensing menthol with a mono- or oligosaccharide, preferably a mono- or disaccharide, i.e., a sugar, or acyl derivative thereof, using a condensing agent or catalyst as needed. These glycosides are hydrolyzed by carbohydrase enzymes, as occur in the human mouth, or common acids, releasing menthol, and provide a more persistent flavor than menthol alone.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
122 words
The method of manifesting upon oral or topical administration to a human being the inherent flavor and feeling of menthol in an aqueous base composition in which menthol is normally insoluble, which comprises the steps of providing in said composition a water-soluble menthol derivative having the formula: ##SPC7## wherein: R is the residue of a mono- or oligosaccharide and n is the number of hydroxyl groups on said mono- or oligosaccharide and is at least 5, and orally or topically administering said composition to a human being, and effecting hydrolysis of said derivative in the administered composition by a carbohydrase enzyme or an acid harmless to human beings to thereby regenerate free menthol from said derivative and manifest said flavor and feeling.
Claim 2
Independent Claim
122 words
The method of manifesting upon oral or topical administration to a human being the inherent flavor and feeling of menthol in an aqueous base composition in which menthol is normally insoluble, which comprises the steps of providing in said composition a water-soluble menthol derivative having the formula: ##SPC7## wherein: R is the residue of a mono- or oligosaccharide and n is the number of hydroxyl groups on said mono- or oligosaccharide and is at least 5, and orally or topically administering said composition to a human being, and effecting hydrolysis of said derivative in the administered composition by a carbohydrase enzyme or an acid harmless to human beings to thereby regenerate free menthol from said derivative and manifest said flavor and feeling.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said composition is administered orally and said hydrolysis is effected in the oral cavity by an enzyme present in human saliva.
