Soap Glycerine

Glycerin-phosphorsaure, /. glycerophoephoric acid, -saure, /. glyceric acid, -seife, /. glycerin soap. 

The type of evaporator, either single or multiple effect, depends on the volume of materials to be processed. The crude glycerine obtained after evaporation has a concentration of 80-88% and undergoes further processing. Salt, which separates out during the evaporation of treated glycerine soap lye, accumulates in a salt pot positioned underneath the evaporator. The salt is recovered and recycled to the soap-making section. 

In the market these soaps are commonly known as traneparent glycerin soaps and they may be prepared from either of the subjoined formulae —... 

Yes, it s just a different name. Many people have heard of glycerine due to it being used in glycerine soaps. 

Not normally - the exception being the translucent glycerine soaps which have glycerol added to them to change their properties. Normal soap is formed when fats and oils are converted into soap (in a process called saponification) by reaction with a base like sodium hydroxide, and glycerol is the waste product.

As is already known, glycerine soaps can now be obtained quite cheaply, they are quite transparent, and look almost like yellow glass, and also have the quality of making a good lather. 

If to heated glycerine, which has been diluted with about one third of its voluiiie cf water, as much finely cut soap is added as can be dissolved therein, without the niass on cooling becoming hard, a, product is the result which in the trade is known under the name (f Liquid Glycerine Soap or Glycerine Cream and, coloured and scented in various manners, forms a very valuable toilet adjunct. 

It is anfortunately impossible to discuss in detail in this work, which is dedicated to the application and properties cf glycerine, the very extensive and important application of glycerine to toilet soap manufacture. Those who are interested in this subject and would like further details should read the work on Soaps by G. H. Hurst, published by Scott, Greenwood Son, London. Here we ean only give a few indications as to the production of glycerine soaps. 

F it is intended to make glycerine soaps by direct saponification—crutching—then the fillingsubstances, glycerine and sugar, should be added to the soap mass immediately after saponification. 

F glycerine soap is to be made by remclting, first of all water is placed in the pan, this is heated, the pieces of soap are added, mixed by stirring with the water, and as regards the addition of glycerine, colouring, and aromatic substances, the same process is followed as above described. 

Liquid glycerine soap of the consistency of syrup is at present a much sought after toilet adjunct, and is mostly coloured with pale brown (honey glycerine soap) or with pale pink aiid perfumed with geranium oil (rose glycerine soap) and supplied to the trade. 

As regards its constitution glycerine soap is a potash soap, dissolved with or without addition of alcohol in very little water and mixed with scented and coloured glycerine. It is produced by saponification (f pure olive oil with potash lye, and dissolving 100 parts of this soap in a mixture composed of 50 parts of water and 50 parts rf alcohol at 40 per cent and adding lO parts of glycerine. This soap solution is a yellow brown and a certain amount rf colouring matter need only be added in order to obtain the honey-coloured article. 

A soap intentionally made alkaline, corresponding to the ordinary glycerine soaps, is particularly suitable for disinfection purposes, and lor this reason should realize a good sale.
