摘要
Spray of discharge drift is controlled in aqueous mixtures with the inclusion of a substantially neutral pH drift control agent containing lecithin, a viscosity modifying agent, and a water dispersing agent. In one embodiment, the viscosity modifying agent is a methyl ester and the water dispersing agent is a polyoxyethylene ether. In a preferred embodiment the viscosity modify agent is methyl soyate and the water dispersing agent has the formula H23C11(CH2CH2O)5H. The lecithin-based drift control agents of the present invention reduce the formation of fine droplets when the mixtures are atomized, thereby reducing the amount of the mixture that drifts outside of the area targeted to receive the spray or discharge.
