Abstract
The present invention relates to emulsions comprising an emulsification system comprising a mixture of at least one cationic surfactant, at least one anionic surfactant, at least one “bridging surfactant”, an oil and water, along with methods for preparing such emulsions. More specifically, the invention relates to stable, synergistic emulsions of various oils, water, cationic, anionic, and bridging surfactants that are useful in preparing a variety of finished personal care, laundry, and cleaning products, including for examples creams, lotions, sunscreens, liquid dish detergents, laundry detergents, automatic dishwasher detergents, hand soaps, laundry bars, personal cleansing bars, multi-purpose cleaners, multi-functional shampoos, body washes, and textile treatment compositions. The emulsifications of the present invention also may be employed in agricultural and pesticide applications. Additionally, the surfactant blends may be utilized in antimicrobial formulations (e.g., antimicrobial hard surface cleaners, hand soaps, shampoos, and dish detergents), soft-terg delivery systems and pre-spotter compositions. The emulsification system of the instant invention, even w…
