Abstract

Methods and compositions for suppression hydrocarbon fumes, and cooking oil fumes, by applying a non-volatile organic compounds having a vapor pressure temperature greater than the vapor pressure temperature of the hydrocarbon fume constituents, or cooking oil fume constituents; said compositions may include delivery vehicles such as 70% ethanol, or thixotropic lotions, to produce remediation formulations that may be sprayed or spread onto the surfaces from which the fumes are emanating; also included is an insect repellant, comprising non-volatile organic compounds having a vapor pressure temperature greater than the vapor pressure temperature of the human pheromones and body odors with attract biting insects.

1 . A method for suppressing petroleum hydrocarbon fumes comprising:

       2 . The method of  claim 1 , further comprising the step of: 
 combining a sufficient amount of the nonvolatile organic compound with a delivery vehicle therefore, selected from the group consisting of acetone, methanol, ethanol, fatty acid esters and alcohols of carbon chain length greater that 18; to form the a remediation formulation; before applying to the petroleum hydrocarbon.    
   
   
       3 .

       4 . The remediation formulation of  claim 3 , wherein more than % by volume of the selected fume suppressors have carbon atom chain lengths equal to or greater than C18.  
   
   
       5 . The remediation formulation of  claim 3 , further comprising a delivery vehicle selected from the group consisting of acetone, methanol, ethanol, fatty acid esters and alcohols of carbon chain length greater that 18, said delivery vehicle comprising between 0.5 and 100% by volume? of the formulation.  
   
   
       6 . The remediation formulation of  claim 3 , wherein the selected fume suppressor is oleic acid.  
   
   
       7 . The remediation formulation of  claim 5 , wherein the selected fume suppressor is oleic acid.  
   
   
       8 . The remediation formulation of  claim 6 , wherein the oleic acid, present at between 5-15% (v/v) of the remediation formulation.  
   
   
       9 . The remediation formulation of  claim 7 , wherein the oleic acid, present at between 5-15% (v/v) of the remediation formulation.  
   
   
       10 . The remediation formulation of  claim 7 , wherein the delivery vehicle for the oleic acid is ethanol at concentration greater than 50% (v/v) in aqueous solution.  
   
   
       11 . The remediation formulation of  claim 3 , wherein the fume suppressor is selected from the group consisting of: soybean oil, olive oil, corn oil, and meadowfoam oil, nonvolatile, biodegradable oils and edible oils.  
   
   
       12 . The remediation formulation of  claim 3  formulated as topical sprays, lotions, creams and gels for application to the human skin to suppress volatile hydrocarbon fumes, said formulation comprising a delivery vehicle comprising ethanol, stearate and palmitate esters, and alcohols.  
   
   
       13 . A method for suppressing fumes from rancid fats comprising: 
 a) identification of the primary volatiles responsible for the rancid fat fumes    b) determination of the vapor pressure temperature for each of the suspected primary volatiles with vapor pressures less than one atmosphere,    c) selection of a nonvolatile organic compound with vapor pressure temperatures that are at least 30 degrees centigrade higher than the highest vapor pressure temperature of the volatile components of the rancid fat fumes, said nonvolatile organic compound selected from the group consisting of fatty acids, alcohols, fats, mineral and vegetable oils, waxes, silicon oils.    d) combining a sufficient amount of the nonvolatile organic compound with a delivery vehicle therefore, selected from the group consisting of acetone, methanol, ethanol, fatty acid esters and alcohols of carbon chain length greater that 18; to form the a remediation formulation; before applying to the petroleum hydrocarbon, and    e) applying the remediation formulation to the rancid fat.    
   
   
       14 . A composition for suppressing fumes due to rancid fats such as butylated fats and fatty acids, and partially decarboxylated breakdown products of edible fats and cooking oils, for the decontamination of cooking surfaces, kitchen appliances, and other surfaces soiled with decomposed cooking fats and oils, said composition comprising the remediation formulation of  claim 3 .  
   
   
       15 . An insect repellant comprising the remediation formulation of  claim 3 , applied topically to the skin, to prevent volatilization of skin-generated pheromones attractive to mosquitoes and other biting insects.
