Unqualified dry sodium soap may be caused by the following points: First, the production company neglects to check the quality of raw materials; second, in order to reduce costs, some companies intentionally use low-quality and low-price raw materials or reduce the input of raw materials; third, Some family-run enterprises have crude production equipment, weak technical strength, unreasonable production formulas or lack of quality control measures, resulting in unstable product quality.
