  • Publication number: 20140037816
    Abstract: Aqueous multiphase compositions are stabilized using a blend of cellulose ether and nanocrystalline cellulose. The multiphase compositions can include particulates dispersed in water, oil in water emulsions, foams, and combinations of these systems. The blend can be used to stabilize aqueous paint systems, personal care products such as shampoos and detergents formed as oil in water emulsions, and foaming products such as detergents, shampoos, other personal care products and edible compositions such as whip cream substitutes. Further, this blend can reduce or eliminate the need for surfactants in many of these multiphase compositions.
