Traditional soap manufacturing processes include ingredient mixing, grinding, pulverizing, and cutting into blocks, using natural oils for saponification.
Green manufacturing is becoming an industry trend, employing techniques such as using natural raw materials like plant derivatives, low-temperature physical continuous mixing technology, high-temperature spray drying technology, and ultra-concentration technology. Through wastewater recycling (e.g., for ingredient mixing or cooling water replenishment) and greywater reuse, zero wastewater discharge or high reuse rates can be achieved.
Synthetic detergents and other products have different production processes depending on their physical state (powder, liquid, paste, etc.) and intended use.
