SAS MARIANI is committed to developing innovative cleansing products and has been collaborating for years with leading companies to supply specialized SOLID SHAMPOO production machines.

Solid shampoo is made by blending powdered surfactants, such as Sodium Cocoyl Isethionate (SCI), with conditioning agents, botanical extracts, and nourishing oils. The dry ingredients are mixed thoroughly before adding liquid components like essential oils and humectants. The mixture is then gently heated to form a moldable paste, which is shaped into bars using molds. Once formed, the shampoo bars are left to cool and harden before being packaged for use. This process eliminates the need for plastic packaging and excess water, making solid shampoo an eco-friendly alternative to liquid formulations.

Since conventional soap lines are unsuitable for high-quality, efficient shampoo bar production, we have designed dedicated equipment for this purpose

 

For optimal SOLID SHAMPOO production in a SHAMPOO BAR FINISHING LINE, we employ:

• Double-Arm Sigma Mixer - an over-dimensioned version with a built-in extruding pelletizer, designed to efficiently mix SCI (Sodium Cocoyl Isethionate) or other surfactants with emulsifiers and additives.

• Roll-Mill - for reducing hard particles in the base, ensuring uniform granulometry.

• Duplex Vacuum Flexi Plodder - ideal for syndet materials, featuring a twin-screw top and our specialized FLEXi stage at the bottom for compact extrusion and precise temperature control, enhanced by turboflow units. Thermoregulated stainless steel screws further optimize performance (see FLEXi page for details).

• Single-blade Cutter - with a heated blade kit, designed for sticky products like solid shampoo bars.

• Condor Flash-Stamping Machine - offering a unique stamping process superior to conventional flash-stamping systems. It ensures precise infeed, accurate extraction, and clean separation of flashings, making it ideal for soft shampoo bars (see the Condor page for details). The material and design of the moulds are specifically engineered for sticky products.
