The meltable base is usually naturally rich in glycerine, a by-product of saponification that has humectant and emollient properties, whereas commercial soap bars have often had this component removed. As with the rebatching method, it can be considered a misnomer to refer to the melt and pour process as soap making. The process has much in ...
Handmade soap makers who aim for bar soap use sodium hydroxide (NaOH), commonly known as lye, rather than KOH (caustic potash) which produces soft paste, gel or liquid soaps. In order to calculate the lye amount needed to make bar soap, KOH values of SV can be converted to NaOH values by dividing KOH values by the ratio of the molecular weights ...
Some soap-makers leave the glycerol in the soap. Others precipitate the soap by salting it out with sodium chloride. Skeletal formula of stearin, a triglyceride that is converted by saponification with sodium hydroxide into glycerol and sodium stearate. Fat in a corpse converts into adipocere, often called "grave wax".
Total fatty matter (TFM) is one of the most important characteristics describing the quality of soap and is always specified in commercial transactions. It is defined as the total amount of fatty matter, mostly fatty acids, that can be separated from a sample after splitting with a mineral acid, usually hydrochloric acid.
For these purposes, lauric acid is reacted with sodium hydroxide to give sodium laurate, which is a soap. Most commonly, sodium laurate is obtained by saponification of various oils, such as coconut oil. These precursors give mixtures of sodium laurate and other soaps. [11]
Rebatching can also be used as a way of salvaging soap that cracked, curdled or separated while being made. As with the melt and pour process, rebatching does not necessarily involve saponification , and as such it is a misnomer to refer to it as soap-"making".
