Patent number: 9138409Abstract: A stable, high VOC, single phase, non-aqueous liquid aerosol composition having enhanced dispersion based on reduced particle size and increased evaporation rate to result in improved active ingredient dispersion, slower settling in air and less residue on surfaces. The composition includes at least one hydrocarbon propellant, at least one active ingredient and a solvent blend. The solvent blend includes at least one low volatility solvent and at least one high volatility solvent wherein each has a defined vapor pressure and Hansen solubility parameter. The composition upon dispersion as a spray has an aerosol particle size of less than 30 microns.Type: GrantFiled: May 31, 2013Date of Patent: September 22, 2015Assignee: S.C.

Publication number: 20130323292Abstract: Disclosed are pyrethrin-based insect control formulations which have been formulated to reduce wick clogging in dispensers which use heaters to drive an insect control active from the wick. Pyrethrum extract is mixed with an acetylenic compound, such as prallethrin or 3,5-dimethylhex-1-yn-3-ol, and a terminal diene compound such as myrcene or 1,3 hexadiene. Wick clogging side effects from using the pyrethrum are thereby suppressed.Type: ApplicationFiled: June 1, 2012Publication date: December 5, 2013Inventors: Lina Long, Brian W. Anderson, Gerald W. Cummings, Francis J. Randall, Jamie T. Huynh, Deliang Shi
