Abstract
Abstract A first starter which is an oil-in-water emulsion whose internal phase is 70% of the emulsion. The emulsion has superior ignitability characteristics due to the use of an emulsifier which is a C12-C20 commercial blend of fatty alcohols that have been ethoxylated and propoxylated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
68 words
An emulsion that acts as a fire starter which has a lipoidal internal phase comprising at least 70% of the emulsion and a nonlipoidal external phase the improvement which comprises emulsifing said internal and external phases with an emulsifier which is an ethoxylated and propoxylated C 12 -C 20 blend of fatty alcohols wherein the mole ratio of ethylene oxide to propylene oxide is between 2-1/2:1 and 3-1/2:1.
Claim 2
Dependent Claim
68 words
An emulsion that acts as a fire starter which has a lipoidal internal phase comprising at least 70% of the emulsion and a nonlipoidal external phase the improvement which comprises emulsifing said internal and external phases with an emulsifier which is an ethoxylated and propoxylated C 12 -C 20 blend of fatty alcohols wherein the mole ratio of ethylene oxide to propylene oxide is between 2-1/2:1 and 3-1/2:1.
Claim 3
Dependent Claim
13 words
