Processing & handling
- Equipment: jacketed mixer (SS 304/316) with anchor/paddle low-RPM stirrer (VFD if available); all contact parts SS 304/316.
- Heating: hot water, steam or hot-oil unit. Mixer must be clean and dry — sanitise with 2% formaldehyde solution if required.
- Add flakes to the mixer. Heat with slow stirring until the soap melts, maintaining temperature below 80 °C.
- Note: heating above 80 °C may turn the product translucent or opaque. Maintain moisture content — add sorbitol / glycerin if necessary.
- Cool the mass to 70 °C. Add colour, fragrance and additives as required (colour as per BIS, Schedule Q preferred; perfume stable at 70–80 °C).
- Transfer the mass to the mould or Schist cooler.
- Stamping: cut and stamp on a manual or automatic stamper in the desired shape, then pack in cartons or shrink wrap.
