  • Hydrophobic agents stably dispersed in oil-in-water emulsions
    Patent number: 8652493
    Abstract: The present invention pertains to oil-in-water emulsion compositions having hydrophobic materials stably dispersed therein and methods for making such. The preferred method of making the emulsion compositions the formation of two O/W emulsions. A first O/W emulsion is for wetting or otherwise pre-treating the hydrophobic components. Thereafter, the first emulsion is added to a second O/W emulsion after the second emulsion has been formed. Both emulsions use a ternary surfactant blend of cationic, anionic and bridging surfactants, making the finished product a double or “binary-CAN” emulsion system. Generally, the system has a bi-modal oil droplet distribution.
