Abstract:
A gel formulation useful in the controlled and sustained release of a vapor containing at least one insecticidally active compound comprising:(a) from about 1.0% to about 95% by weight of at least one pyrethroid; (b) from about 1% by weight to about 12% by weight of a gel former; and (c) from about 10% by weight to about 90% by weight of a vaporization modifier selected from the group consisting of medicinal white oils and high-pressure hydrogenated mineral oils having CAS No. 8042-47-5, rapeseed oil, rapeseed oil methyl ester, Guerbet alcohols and combinations and mixtures thereof, wherein said vaporization modifier is present in an amount sufficient to modify the vaporization rate of said gel formulation at an operating temperature from about 70Â° C. to about 110Â° C.; and wherein said gel formulation forms said vapor containing at least one pyrethroid upon heating to said operating temperature, whereby surfaces exposed to said vapor remain substantially free of residues of said vaporization modifier during use of said gel formulation.
