PROBLEM TO BE SOLVED: To provide a soap of which decomposition proceeds in an environment and that has less influence on the natural environment, after being discharged with water, by making readily usable a washing agent that does not have slimy feeling and residual film feeling derived from a synthetic surfactant, is easy to rinse, has smooth feeling at the finish of cleansing, and can be always used cleanly.SOLUTION: After specifying a blending balance of a fatty acid sodium soap basis, water, oil and air, by kneading, mixing and crushing while engulfing air by a mixer having a predetermined shearing force and torque to make a particle size of gas-liquid micelles and liquid-liquid micelles smaller, the fluidity is stabilized.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】合成界面活性剤由来のぬるぬる感、残膜感が伴わない、すすぎが楽で、洗い上りがさっぱりとして、いつも清潔に使用できる洗浄剤を手軽に利用できるようにする。また、排水後に、環境中で分解が進み、自然環境に与える影響は少ない石鹸を提供する。【解決手段】脂肪酸ナトリウム石鹸素地、水、油、空気の配合バランスを特定し、気液ミセル、液液ミセルの粒子径を小さくするため、所定の剪断力と回転力を有するミキサーで空気を巻き込みながら混錬、撹拌、粉砕し、流動性を安定化させる。【選択図】なし
