Abstract
The invention discloses a composition and method of absorbing and/or detecting the presence of ignitable liquids. The composition includes a hydrophobic polymer, a hydrophobic long-chain carboxylic acid and, optionally, a hydrophobic solvent indicator dye and a hydrophobic white metallic oxide. The composition may be applied to an area suspected of containing an ignitable liquid and allowed to remain on the area for a time period sufficient to react with the ignitable liquid. If an ignitable liquid is present, the composition will form an aggregate by agglomeration with the ignitable liquid.

A method of absorbing and/or detecting one or more ignitable liquids comprising:
- applying a composition comprising a hydrophobic polymer, a hydrophobic solvent indicator dye, a hydrophobic white metallic oxide, and a hydrophobic long-chain carboxylic acid to an area suspected of containing one or more ignitable liquids;
- and
- allowing the composition to remain on the area for a period of time sufficient for the composition to react and form an aggregate with one or more of the ignitable liquids.
A method of manufacturing a composition for detecting the presence of one or more ignitable liquids comprising:
- heating a hydrophobic long-chain carboxylic acid at a temperature sufficient to melt but not boil the hydrophobic long-chain carboxylic acid;
- adding the hydrophobic polymer to the melted hydrophobic long-chain carboxylic acid to form a homogenous mixture;
- cooling the homogenous mixture to ambient temperature;
- grinding the cooled homogenous mixture to form a powder;
- and
- mixing a hydrophobic indicator dye into the powder.
A composition for absorbing and/or determining the presence of an ignitable liquid comprising:
- about 60-90% by weight of a hydrophobic polymer;
- about 10-40% by weight of a hydrophobic long-chain carboxylic acid;
- about 0.02-3.0% by weight of a hydrophobic solvent indicator dye;
- and
- about 7-22% by weight of a hydrophobic white metallic oxide.
