METHOD FOR PRODUCING EMULSION COMPOSITION

WIPO Patent Application WO/2023/074603

A1

The present invention provides a method for producing an emulsion composition which contains a component (A) that is composed of one or more polymers selected from the group consisting of cationic polymers and amphoteric polymers, a component (B) that is composed of an anionic polymer, a component (C) that is composed of an organic acid, and a component (D) that is composed of water, the method comprising step (1) described below and either step (2-1) described below or step (2-2) described below. With respect to this method for producing an emulsion composition, the total blending amount of the component (A) and the component (B) in the emulsion composition is less than 1.0% by mass in a total of 100% by mass of the emulsion composition. Step (1): a step in which a mixture A that contains the components (A) to (D) is prepared Step (2-1): a step in which an emulsion (I) is prepared by mixing the mixture A with an oil phase component that contains an emulsion-forming constituent Step (2-2): a step in which an emulsion (II) is prepared by mixing an oil phase component that contains an emulsion-forming constituent with an aqueous phase component other than the mixture A, and subsequently, the emulsion (II) is mixed with the mixture A
