Larger ratios of hydrophobic substance-to-saccharide yields a spun fibrous product that has increased stability. Similar stabilization can be attained by adding either beeswax or a petrolatum to the saccharide either in the presence of or absence of a separate active ingredient. Examples are given for masking the taste of unpalatable medicaments or other ingestible substances. Delayed release burn or wound dressings are also described. Control with beeswax can also provide a time release tablet or the like when swallowed.Field of SearchDESIGNATED ORGANIC NONACTIVE INGREDIENT CONTAINING OTHER THAN HYDROCARBONCarbohydrate or lignin, or derivative Cellulose or derivative CONTAINING DESIGNATED INGREDIENT TO REDUCE NOXIOUS EFFECTS OF ACTIVE INGREDIENT (E.G., TASTE MASKING, ODOR REDUCING, ETC.)
