Framing process and milling process

The completed soap is poured into a mold and left to cool and solidify for several hours. This process is called "framing" and the molded soap is cut into several bars.

On the other hand, "milling" solidifies and molds the soap into perfect shape within a short period of time. Therefore, milling allows soap manufacturers to produce soap in massive quantities. Because milled soaps are easy and quick to make, they are cheaper compared to additive- and preservative-free framed soaps.

Milled soap vs. framed soap
  Merit Demerit
Milled soap
  • Producing milled soaps in mass numbers can be cost-effective
  • Can be made within a short period of time
  • Produces more lather
  • Does not melt easily
  • Uses surface-active agents or surfactants
  • Contains several chemical compounds such as additives and stabilizers
  • Such as natural glycerin is removed in most milled soaps
  • Mostly consists of soap base and contains less cosmetic substances
Framed soap
  • Rich in natural glycerin that provides moisture to our skin
  • Produces a very smooth lather
  • Framing allows soap to retain rich features that are good for our skin
  • Aged while being dried naturally
  • Safe to use because it contains less additives
  • Contains less or no chemical preservatives
  • Does not produce more lather compared to milled soaps
  • Melts easily compared to milled soap
  • Making framed soap takes a great deal of time, so it is unsuitable for mass production
  • Expensive compared to milled soap


Milled soap, as its name goes, is a soap that is all manufactured by machine-assisted technology.
Milling allows the mass and low-cost production of soap because all the ingredients are refined, completed and then molded by a machine all at once. Because milled soaps are inexpensive, produce more lather and have high cleansing powers, they are mainly used as common facial soaps.
