  • Publication number: 20080292855
    Abstract: A substrate for delivering a fragrance to the surroundings is disclosed, wherein the substrate comprises: (i) at least one copolymer of an olefin and one or more ethylene derivatives selected from a group consisting of vinyl esters of saturated carboxylic acids, propenyl esters of saturated carboxylic acids, olefmically unsaturated organic acids or esters, and mixtures thereof, and (ii) a fragrance in an amount sufficient to be released to the surroundings at a sustained, controlled rate. Preferably, the substrate is in a form of a transparent sheet so that the substrate can be conveniently and discreetly attached to a surface and deliver a fragrance impregnated therein to the surroundings.

  • Patent number: 5591395
    Abstract: A method of disinfecting the air and killing air borne bacteria, etc., by creating particles of disinfecting compounds using a heated wick is disclosed. More particularly, this invention relates to a method of generating particles of compounds which are known to kill air borne bacteria when these compounds are dispersed in the air in the fore of small particles by generating these particles using a wick which is indirectly heated at near the top. The compositions include glycols selected from the group consisting of propylene glycol, dipropylene glycol, triethylene glycol and mixtures thereof.
