Preparing an aqueous phase to form a hydrophilic chain by mixing acrylic acid, water, acrylamide, methacrylic acid, and ammonia; Preparing an oil phase which forms a hydrophobic chain by mixing a hydrophobic emulsifier having a HLB value of 4-6.5 with a silicone or ester oil; The reverse phase emulsion polymerization step of reacting the water phase into the oil phase, forcibly emulsified with a homogenizer, and then by adding an initiator to change the color of the emulsion from milky white to transparent and again milky white. |
