Toilet Soap Noodles TFM 70 - 72% (45:45:10)

Brief Overview

Sodium hydroxide is used to saponify vegetable oils, such as palm, coconut, olive, and/or animal fat (tallow), to create soap noodles. Soap noodles are claimed to have been the first known forms of soap. Both amateur and expert soap makers use soap noodles because they are simple to personalize with colors, flavors, and other ingredients to produce soap. Additional methods that can be applied to further modify the finished soap product include molding, pressing, and stamping.

Manufacturing Process

The main process for producing soap, direct saponification, is mixing sodium hydroxide with triglyceride. Hydrolyzing fats and oils produces glycerol and fatty acids as byproducts. Sodium hydroxide is then used to neutralize these fatty acids. Methyl esters are produced when fat or oil is transesterified using methanol. Methanol is a byproduct and soap is created when the methyl ester is saponified with sodium hydroxide.

Detergent Industry

Soap mixes are homogenized using worm screws or rollers operating at high pressure. A thin soap sheet or many layers are produced by this method and are extruded through a perforated endplate. The homogenized soap is compressed into a continuous bar using a plodder. Different kinds of soap, including toilet, laundry, transparent, high-lather, and therapeutic soaps, are produced by varying the characteristics of soap noodles.
