SOLUTION: This composition is prepared by adding, desirably, about 0.0005 to about 0.25 wt.% organoleptic masking agent component to a carrier composition containing a mixed urethane/urea resin desirably being a reaction product of an isocyanate with an alcohol being at least one member selected among monohydric aliphatic, monohydric aromatic, monohydric aliphatic/aromatic, monohydric fused-ring alcohols and polyols and/or a reaction product of at least one alcohol with an isocyanate and at least one monoamide. It is desirable that the above component is selected among esters, lactones, aldehydes, ketones, alcohols, ethers, acetals, ketals, heterocycles, and compositions containing a pheromonhe, acetylene, an amine, and a mixture thereof and having cumulative double bonds. |
