Abstract

Abstract Improved wax compositions suitable for the preparation of candles, as the sole fuel component or as an overdip applied to a paraffin or paraffin/fatty acid candle, are provided. The compositions of this invention are a blend of a paraffin, a C16 or C18 saturated fatty acid or mixture of said fatty acids, and an alpha-alkyl-branched carboxylic acid obtained by the free radical addition of a C20-44 alpha-olefin or alpha-olefin mixture and a carboxylic acid having 3 to 36 carbon atoms. A process for improving the surface characteristics of paraffin or paraffin/fatty acid candles by applying the present wax compositions thereto as an overdip and the resulting improved candles obtained therefrom are also disclosed.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 105 words
A process for improving the surface characteristics of a paraffin or paraffin/fatty acid candle by dipping said candle into a wax composition comprising (a) a paraffin melting inthe range 50° C. to 65° C., (b) a C 16 or C 18 saturated fatty acid or fatty acid mixture comprised predominantly of C 16 and C 18 saturated fatty acids, and (c) an alpha-alkyl-branched carboxylic acid obtained by the free radical addition of a C 20-44 alpha-olefin or alpha-olefin mixture with a carboxylic acid having from 3 to 36 carbon atoms, to apply one or more layers of essentially uniform thickness of said wax composition thereto.
Claim 2
Dependent Claim 105 words
A process for improving the surface characteristics of a paraffin or paraffin/fatty acid candle by dipping said candle into a wax composition comprising (a) a paraffin melting inthe range 50° C. to 65° C., (b) a C 16 or C 18 saturated fatty acid or fatty acid mixture comprised predominantly of C 16 and C 18 saturated fatty acids, and (c) an alpha-alkyl-branched carboxylic acid obtained by the free radical addition of a C 20-44 alpha-olefin or alpha-olefin mixture with a carboxylic acid having from 3 to 36 carbon atoms, to apply one or more layers of essentially uniform thickness of said wax composition thereto.
Claim 3
Dependent Claim 71 words
The process of claim 1 wherein (a) has a melting point in the range 54° C. to 61° C., (b) has a titer in the range 54° C. to 60° C., and (c) is derived from an alpha-olefin mixture wherein 85 percent or more of the olefins contain 26 to 40 carbon atoms and a monocarboxylic acid having from 3 to 22 carbona toms reacted on an essentially 1:1 molar basis.
Claim 4
Dependent Claim 21 words
The process of claim 2 wherein the monocarboxylic acid is a C 12-18 saturated fatty acid or mixture of fatty acids.
Claim 5
Dependent Claim 14 words
A candle obtained in accordance with the process of claim 1, 2, or 3.
