Abstract
Abstract A technique is described for neutralizing unishiol. The technique involves contacting urushiol with a chlorine-containing compound in a liquid medium. In one embodiment the chlorine-containing compound is sodium or calcium hypochlorite in an aqueous solution. In another embodiment the chlorine-containing compound is a chloramine in a liquid organic medium.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
A method for decontaminating a surface which has been exposed to urushiol, said method being for the purpose of neutralizing said urushiol, wherein said method comprises contacting said urushiol with an effective amount of a solution of a chlorine-containing compound which is capable of reacting with urushiol to produce non-allergenic reaction products, wherein said solution is selected from the group consisting of: (a) an aqueous solution of sodium or calcium hypochlorite further containing an alkali selected from the group consisting of carbonates, bicarbonates, hydroxides, and methoxides; and (b) an N-chloramine in a liquid organic medium selected from the group consisting of ketones, acetates, and chlorinated solvents.
Claim 2
Independent Claim
106 words
A method for decontaminating a surface which has been exposed to urushiol, said method being for the purpose of neutralizing said urushiol, wherein said method comprises contacting said urushiol with an effective amount of a solution of a chlorine-containing compound which is capable of reacting with urushiol to produce non-allergenic reaction products, wherein said solution is selected from the group consisting of: (a) an aqueous solution of sodium or calcium hypochlorite further containing an alkali selected from the group consisting of carbonates, bicarbonates, hydroxides, and methoxides; and (b) an N-chloramine in a liquid organic medium selected from the group consisting of ketones, acetates, and chlorinated solvents.
Claim 3
Independent Claim
13 words
A method in accordance with said 1, wherein said surface comprises wearing apparel.
Claim 4
Independent Claim
13 words
A method in accordance with said 1, wherein said surface comprises wearing apparel.
Claim 5
Dependent Claim
34 words
A method in accordance with claim 1, wherein the solution is the N-chloramine in said liquid organic medium and the concentration of N-chloramine in said medium is between about 0.5 to 5% by weight.
Claim 6
Dependent Claim
32 words
A method in accordance with claim 1, wherein said solution is the N-chloramine in said liquid organic medium, the N-chloramine comprises trichloroisocyanuric acid and said organic medium comprises acetone and butyl acetate.
Claim 7
Dependent Claim
31 words
A method in accordance with claim 1, wherein said solution further comprises a solution modifier selected from the group consisting of low molecular weight alcohols, aliphatic hydrocarbons, acetone alcohol and water.
Claim 8
Dependent Claim
25 words
A method in accordance with claim 1, wherein said solution of a chlorine containing compound is applied to said surface by spraying, wiping, or immersion.
Claim 9
Dependent Claim
36 words
A method in accordance with claim 1, wherein said solution is the N-chloramine in the liquid organic medium and the N-chloramine is selected from the group consisting of chloroisocyanurics, chlorinated hydantions, chloramine-T, N-chlorosuccinimide, trichloromelamines, and N-chlorosulfonamides.
Claim 10
Dependent Claim
25 words
A method in accordance with claim 1, wherein said N-chloramine is selected from the group consisting of trichloroisocyanuric acid, dichloroisocyanuric acid, 1,3-dichloro-5,5-dimethyl hydantoin, and chloramine-B.
Claim 11
Dependent Claim
20 words
A method in accordance with claim 1, wherein said solution further comprises indicator means for indicating the presence of urushiol.
Claim 12
Dependent Claim
26 words
A method in accordance with claim 9, wherein said indicator means comprises an alkali selected from the group consisting of sodium and potassium hydroxides and carbonates.
Claim 13
Dependent Claim
28 words
A method in accordance with claim 9, wherein said indicator means is selected from the group consisting of ferric nitrate, ferric ammonium citrate, ferric chloride and ferric acetate.
