Kind Code:
A
Abstract:
To provide a method for producing an emulsion composition which contains a polyion complex, has high stability, can improve a touch feel of the hair after treatment when used as a hair cosmetic composition and can inhibit hair from spreading under a high humidity condition.SOLUTION: There is provided a method for producing an emulsion composition which comprises a component (A): one or more polymers selected from the group consisting of a cationic polymer and an amphoteric polymer, a component (B): an anionic polymer, a component (C): an organic acid and a component (D): water, and the method comprises the following step (1) and either one of the step (2-1) or step (2-2), wherein the total blending amount of the component (A) and the component (B) in the emulsion composition is less than 1.0 mass% in 100 mass% of the total amount of the emulsion composition. Step (1): a step of preparing a mixture A containing the above components (A) to (D), step (2-1): a step of preparing an emulsion (I) by mixing the mixture A with an oil phase component including an emulsion-forming component, step (2-2): a step of preparing an emulsion (II) by mixing the oil phase component including the emulsion-forming component and a water phase component other than the mixture A, followed by mixing the mixture A.SELECTED DRAWING: None
