Abstract
Abstract Described are candle compositions which may be opaque or transparent or pastel shaded which are adapted to incorporate compositions which are both perfumes and insect repellents, without flashing during burning, such compositions comprising as the basic components a mixture of (a) a hydrocarbon wax or (b) a thermoplastic polyamide resin formed from linoleic acid polymerized with a polyamine compound taken together with an alkanol amide or alkanol amine and a stearic acid compound or (c) a straight chain aliphatic amide in combination with light mineral oil and alcohol; compositions (a), (b) or (c), supra, taken further together with a mixture containing: From 1-30 parts by weight of a methyl heptenone; From 1-10 parts by weight of coumarin; and From 0.4-15 parts by weight of indole; taken alone or taken together with a perfume composition substantially inactive from an insect repellent standpoint.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A candle comprising a molded hydrocarbon wax composition having a protruded wick embedded therein, said molded hydrocarbon wax composition consisting essentially of: (a) A crystalline paraffin wax; and (b) A perfuming and insect repelling quantity of a composition of matter consisting essentially of: (i) From 1 up to 30 parts by weight of at least one methyl heptenone having a structure selected from the group consisting of: ##STR8## (ii) From 1 up to 10 parts by weight of coumarin; and (iii) From 1 up to 15 parts by weight of indole.
Claim 2
Dependent Claim
91 words
A candle comprising a molded hydrocarbon wax composition having a protruded wick embedded therein, said molded hydrocarbon wax composition consisting essentially of: (a) A crystalline paraffin wax; and (b) A perfuming and insect repelling quantity of a composition of matter consisting essentially of: (i) From 1 up to 30 parts by weight of at least one methyl heptenone having a structure selected from the group consisting of: ##STR8## (ii) From 1 up to 10 parts by weight of coumarin; and (iii) From 1 up to 15 parts by weight of indole.
Claim 3
Dependent Claim
14 words
The candle of claim wherein the methyl heptenone is 2-methyl-3-hepten-5-one having the structure: ##STR9##
Claim 4
Dependent Claim
36 words
The candle of claim 1 wherein the perfuming insect-repelling composition consists essentially of 9 parts by weight of at least one methyl heptenone; 3.3 parts by weight of coumarin and 8.3 parts by weight of indole.
Claim 5
Dependent Claim
11 words
The candle of claim 1 containing, in addition, a non-insect-repellent perfume.
Claim 6
Dependent Claim
12 words
The candle of claim 2 containing, in addition, a non-insect repellent perfume.
Claim 7
Dependent Claim
12 words
The candle of claim 3 containing, in addition, a non-insect repellent perfume.
Claim 8
Dependent Claim
96 words
A process for imparting perfuming and insect repelling properties to a candle composition comprising the steps of: (i) intimately admixing a crystalline paraffin wax with a perfuming and insect repelling quantity of a composition of matter consisting essentially of: (a) from 1 up to 30 parts by weight of at least one methyl heptenone having a structure selected from the group consisting of ##STR10## (b) from 1 up to 10 parts by weight of coumarin; and (c) from 1 up to 15 parts by weight of indole; and (ii) fabricating the resulting mixture into a candle.
Claim 9
Dependent Claim
96 words
A process for imparting perfuming and insect repelling properties to a candle composition comprising the steps of: (i) intimately admixing a crystalline paraffin wax with a perfuming and insect repelling quantity of a composition of matter consisting essentially of: (a) from 1 up to 30 parts by weight of at least one methyl heptenone having a structure selected from the group consisting of ##STR10## (b) from 1 up to 10 parts by weight of coumarin; and (c) from 1 up to 15 parts by weight of indole; and (ii) fabricating the resulting mixture into a candle.
Claim 10
Dependent Claim
15 words
The process of claim 7 wherein the methyl heptenone is 2-methyl-3-hepten-5-one having the structure: ##STR11##
Claim 11
Dependent Claim
38 words
The process of claim 7 wherein the perfuming and insect repelling composition consists essentially of 19 parts by weight of at least one methyl heptenone; 3.3 parts by weight of coumarin and 8.3 parts by weight of indole.
Claim 12
Dependent Claim
27 words
The process of claim 7 wherein there is additionally added to the methyl heptenone-coumarin-indole mixture an additional non-insect repellent perfume prior to admixture with the paraffin wax.
