Abstract: An apparatus and method is disclosed for containment and recovery of water-insoluble liquids, e.g., oil, floating on water. The apparatus and method involves using a fibrous material coated or saturated with a composition which will absorb substantial quantities of the water-insoluble organic liquid (oil) while substantially repelling the water in which the water-insoluble organic liquid is floating. The fibrous material may be a fabric, a paper, a sponge, a sheet or a film and is coated or impregnated with an oleophylic, hydrophobic composition. Such materials as cotton, jute, hemp, wool, Rayon, Dacron, paper, polyester, and polyurethane, in various forms and combinations may be used.

Abstract: A sprayable composition for deterring criminals, e.g., muggers, robbers, rapists, etc., consists essentially of a sprayable lachrymatory agent, such as MACE (chloroacetophenone) or orthochlorobenzyl-malononitrile dissolved in N,N-dimethyl formamide or N,N-dimethyl acetamide, or the like, admixed with a minor but effective amount of a dye which is substantive for human skin and difficult to remove and a minor but effective amount of a persistent odorant such as oil of skunk (a complex mercaptan), aliphatic diamines, such as putrescine (tetramethylene diamine) or cadaverine (pentamethylene diamine), or the like. The composition is supplied in a pressurized canister of the type conventionally used for containing and spraying MACE and when sprayed on an at-tacker repels the attacker and identifies him both by the stain and the smell.
