Difference Between Laundry Soap and Toilet Soap

Laundry soap and toilet soap are two mainstream soap products in global market. Most soap factories produce both types to capture more market demand. But many new producers do not know that these two soaps require different settings on soap making machine and different process parameters in soap production line.

Laundry soap is mainly used for fabric cleaning. It focuses on strong detergency, low cost and high hardness. Its fatty acid content is relatively lower, and more filler materials can be added into soap base. In production, laundry soap uses single-stage soap plodder. The extrusion pressure requirement is lower, and surface smoothness requirement is not strict. The saponification process can adopt simplified washing and finishing procedure, which improves production speed and reduces raw material cost. Laundry soap machine usually runs at higher hourly output for mass production.

Toilet soap is used for body washing, so it requires mild formula, fine texture, smooth surface, stable foam and low irritation. Its soap base needs thorough washing to remove excess glycerin, alkali and impurities. In soap production line for toilet soap, two-stage soap plodder is necessary. The two-stage extrusion fully removes air bubbles inside soap base and compacts soap material, so the finished toilet soap will not turn soft easily. The soap cutting and stamping unit also needs high-precision molds to get clear brand logo and neat edges.

The front saponification section shares the same saponification pot for both soap types. But operators need to adjust oil formula, salt dosage and washing times. Toilet soap needs more washing cycles to reduce free alkali content, which is critical to avoid skin irritation. After finishing section, different soap base will flow into different soap finishing lines.

TJ Bright Machinery designs flexible soap production line, which can switch between laundry soap and toilet soap production by adjusting process parameters and changing die heads on soap plodder. Our soap making machine supports flexible formula adjustment. When you switch product types, our technical team can guide your workers to adjust temperature, pressure and material feeding speed.

If your factory plans to produce both products, we can customize the soap production line configuration to balance investment and production flexibility. Our soap making equipment is widely used to produce laundry soap, toilet soap, transparent soap and multipurpose soap.
