Definitions

• compositions comprising one or more phosphate derivatives, and carrier materials wherein the compositions are in a form suitable for oral or topical administration.
• These compositions preferably contain a safe and effective amount of one or more active materials such as those which provide nutritional, therapeutic, antimicrobial, pharmaceutical, medicinal, and/or aesthetic benefit, and those commonly used in health care products.
• a wide variety of flavor, coolant and sweetener agents are used in consumer and health care products today.
• Aesthetic qualities of these compositions such as taste, smell, mouthfeel, and after-taste are important concerns for consumer acceptability. Products with poor flavor, a bad after-taste or other negative aesthetics may limit consumer acceptability initially or over an extended period of time, thereby limiting consumer usage and compliance with treatment regimens.
• An additional aspect of consumer acceptability and compliance is the consumer's perception of efficacy. Consumer satisfaction with a product is likely to be increased if some type of sensory signal exists to remind the consumer that the product is working after ingestion, administration or expectoration.
• phosphate derivatives comprising flavor, coolant, and/or sweetener components may be incorporated into oral or topical compositions to deliver pleasing aesthetics and high consumer acceptability. It has also been discovered that these compositions for oral or topical administration may be formulated to include a safe and effective amount of one or more actives. These compositions may provide sustained coolant, flavor and/or sweetener activity, depending on the particular derivative being used. These phosphate derivatives may also serve to improve the aesthetics of the compositions and provide a sensory signal to the user.
