Abstract
The invention relates to an emulsion composition, wherein an optically isotropic surfactant phase containing a nonionic surfactant (hereinafter the phase being referred to as the surfactant phase) is present as stable droplets in an aqueous solution phase containing an electrolytic salt (hereinafter the phase being referred to as the aqueous solution phase), the amount of the salt being such an amount that the aqueous solution phase is incompatible with the surfactant phase, with a polymer including a segment (a) having affinity with the aqueous solution phase and a segment (b) having affinity with the surfactant phase; and a liquid detergent composition containing the emulsion composition and inorganic builder particles dispersed in the emulsion composition.
