What Is French Milled Soap?

Making French milled soap involves a special manufacturing process that includes passing a soap base through steel rollers. The result is a dense, long-lasting bar. Although real French milled soap is a commercial product, a homemade version exists.

Milling Process

French milled soap begins with crystals made from previously manufactured soap. The crystals go through a pair of stainless steel rollers known as a French mill.

Results

The milling process turns the mixture into a fine paste and makes the soap mixture smooth and homogeneous. It also removes glycerin, which would stick to the rollers.

Significance

The French milling process ensures that each bar is consistent in color, fragrance and texture. True French milled soap is factory-made.

Rebatching

Rebatching, or hand milling, is the handmade equivalent of French milled soap. Soap makers melt shredded or diced soap pieces in a liquid and pour the mixture into molds to harden.

Considerations

French milled soap is sometimes called "triple milled" because the soap mixture passes through the steel rollers at least three times before it is molded into bars or cakes.
