US Classification:

424755, 514514, 424769, 424760, 424773, 514617

Abstract:

The present invention is directed to a sensate composition consisting of a liquid cooling composition, and at least one warming, tingling, or pungent sensate ingredient of either synthetic or natural origin which provides enhanced warming, tingling, or pungent properties. The liquid cooling sensate of the invention is a eutectic mixture of 2-Isopropyl-N,2,3-trimethylbutyramide and N-Ethyl-p-menthane-3-carboxamide, or at least one cooling agent selected from the group consisting of N-(2-hydroxyethyl)-2,3-dimethyl-2-isopropylbutanamide, N-(3-ethoxypropyl)-2,3-dimethyl-2-isopropylbutanamide, N-(3-isopropoxypropyl)-2,3-dimethyl-2-isopropylbutanamide, N-(3-butoxypropyl)-2,3-dimethyl-2-isopropylbutanamide,N-Ethyl-2,2-diisopropylbutanamide, N-(1,1-dimethyl-2-hydroxyethyl)-2,2-diethylbutanamide, N-(2-ethoxyethyl)-2,3-dimethyl-2-isopropylbutanamide and N-(3-methoxypropyl)-2,3-dimethyl-2-isopropylbutanamide. The warming, tingling, or pungent sensate of the invention consists of at least one component that is an isothiocyanate and/or an amide or a natural product that contains at least one warming, tingling, or pungent principle that is an isothiocyanate and/or an amide. The present invention is further directed to a method of using the sensate composition in a food, pharmaceutical or personal care product.

International Classification:

A23L 1/22

US Classification:

426534000

Abstract:

Disclosed is a liquid composition containing N-Ethyl-p-menthane-3-carboxamide and 2-Isopropyl-N,2,3-trimethylbutyramide (popularly known as WS-3 and WS-23 respectively), its preparation and its applications as a cooling sensate and as a flavoring agent. The present invention provides a composition characterized in that it comprises N-Ethyl-p-menthane-3-carboxamide and 2-Isopropyl-N,2,3-trimethylbutyramide in a ratio by weight in the range of 60/40 to 30/70 with the corresponding crystallization point being below 15 C. Preferably a weight ratio of 52/48 to 42/58 is employed corresponding to a crystallization point below −20 C. Such compositions have the advantages of being liquid at room temperature, easy to use as a cooling agent or a flavoring agent with no need to melt the normally crystalline forms of 2-Isopropyl-N,2,3-trimethylbutyramide (melting point 62 C.) and N-Ethyl-p-menthane-3-carboxamide (melting point 98.7 C.). The liquid cooling compositions herein described not only saves handling time, but also simplifies manufacturing processes by eliminating the need for extensive dust control procedures and can be used in cold processes at room temperature. These liquid compositions are effective not just as cooling agents, but at low levels act as flavor and salt enhancers.
