1. A candle formed of a wax composition, said wax composition comprising:
- (a) a low molecular weight ethylene vinyl acetate, having a molecular weight of at most about 5000 molecular weight units;
(b) a high molecular weight alcohol, having about 18 to about 22 carbons;
(c) at least one odorant; and
(d) a paraffin wax having the formula CnH2n+2, where n is between about 18 and 30, the melting temperature of the paraffin wax is between about 120 and about 160, and the paraffin wax contains 85% or more straight-chain paraffins,wherein the combination of said low molecular weight ethylene vinyl acetate, said high molecular weight alcohol, and said wax operate to substantially retain the at least one odorant in said candle when said wax composition is exposed to temperatures below a melting point of said wax composition, and to emit said at least one odorant from said candle when said wax composition is exposed to temperatures at or above the melting point of said wax composition, andwherein said composition contains substantially no microwax.

Abstract
A wax composition comprising a high molecular weight aliphatic alcohol, a low molecular weight ethylene vinyl acetate copolymer, at least one odorant, and a wax. The odorant is substantially retained in the wax composition when the wax composition is exposed to temperatures below a melting point of the wax composition. Furthermore, the odorant is emitted from the wax composition when the wax composition is exposed to temperatures at or above the melting point of the wax composition.

15. A method of making a candle, comprising the steps of:
-
(a) heating a wax at least to its melting point; (b) mixing (i) a low molecular weight ethylene vinyl acetate, having a molecular weight of at most about 5000 molecular weight units, (ii) a high molecular weight alcohol, having about 18 to about 22 carbons, and (iii) at least one odorant with the wax to form a wax composition; (c) casting the wax composition in a mold, wherein the combination of the low molecular weight ethylene vinyl acetate, the high molecular weight alcohol, and the wax operate to substantially retain the at least one odorant in the candle when the wax composition is exposed to temperatures below a melting point of the wax composition, and to emit the at least one odorant from the candle when the wax composition is exposed to temperatures at or above the melting point of the wax composition. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A candle formed of a wax composition and a wick, said wax composition comprising:
-
(a) a low molecular weight ethylene vinyl acetate; (b) a high molecular weight alcohol; (c) at least one odorant; and (d) a wax, wherein the combination of said low molecular weight ethylene vinyl acetate, said high molecular weight alcohol, and said wax operate to substantially retain the at least one odorant in said candle when said wax composition is exposed to temperatures below a melting point of said wax composition, and to emit said at least one odorant from said candle when said wax composition is exposed to temperatures at or above the melting point of said wax composition, and wherein said composition contains substantially no microwax.
