OILS & FATS
In Handmade soap manufacturing (also called Cold Process) it is possible to use a variety of oils with carbon chains with different lengths, from C8 to C20.
In Industrial soap manufacturing the majority of Fatty Matters have chains from 12 to 18 carbons; longer and shorter carbon chains produce a soap not easy to work with industrial machines, due to the properties as hardness and titre.
In both cases (Cold Process and Industrials soap manufacturing) it is necessary to use a blend of fatty matters to mix the carbon chains and obtain a soap with the best performances.
For example chains shorter then 12 carbons give a skin irritant soap, while chains longer than 18 carbon produce a too soft soap. Lauric carbon chain (C12) produces foamy soap but with limited detergent property. Palmitic and Stearic carbon chain (C16 - C18) produces soap with very good detergent property but also too hard. Oleic carbon chain (C18.1) produce a soap with good foam, solubility and detergency, but too soft and with a poor stability.
