The invention relates to a household chemicals manufacturing technique, in particular to a genuine soap washing-powder manufacturing technique, which solves the problems of no hard water tolerance, low solubility and weak detergency caused by sodium stearate added into the powder in the genuine soap washing-powder of the prior art. The weight percentages of integrants comprised in the genuine soap washing-powder are 5-30 portions of surface active agent, 2-40 portions of eunatrol, 20-70 portions of washing auxiliary detergent, 0.1-10 portions of auxiliary material and 5-50 portions of sodium sulfate used as plugging compound. Different manufacturing techniques are applied for adding the oleic acid or eunatrol into the washing-powder. The invention has the advantages of strong detergency, no skin irritation, no environment pollution, simple application, easy manufacturing, environment protection, high efficiency and low production cost.
