of potassium soap and an excess of stearic acid; the combination gives a slower drying lather. Milled toilet soap is another type of bar soap. Because of the milling operation, the soap lathers better and has a generally improved performance, especially in cool water. Laundry soap bars are precursors of the chip and the powder forms.
an ice bath if available). Soft, white lumps of the soap will gradually form in the mixture. Leave for a few minutes to improve the yield. During this time the soap may rise to the surface and form a soft crust on cooling. A quicker method of making soap takes under five minutes. In this

Jan 13, 2012 · “soap scum”. Since soap forms a precipitate with these ions, it means that many of the soap molecules are no longer present in the solution. Therefore, soap will form fewer suds in hard water. “Soft water” is water that contains very few or no ions that precipitate with soap. Soap will therefore be much more effective in soft water than in
