There are several ways of making soap. Cold process is generally considered to be the most natural because the maker has control of the saponification process. Saponification involves the hydrolysis of fats (triglycerides) with an alkali, such as sodium or potassium hydroxide. This reaction leads to the formation of salts of fatty acids and glycerol or soap. Controling the “trace”, or thickness of the batter, is what allows for each bar’s unique design process. This is manipulated by factors such as water content, temperature, fragrance, and fatty acid profile.
The short answer is no. Saponification is the chemical process of making soap that involves an exothermic reaction between lye (sodium hydroxide) and a fat (oils and butters). Soap cannot be made without using lye. When made correctly, no lye will remain in the bar of soap. The saponification generally takes about 24 to 48 hours to complete once the lye and oils have been mixed and the raw soap has been poured into the mold. Both solid bar and liquid soaps are made from lye.
Handmade soap is gentler on your skin. Industrial made soaps are made in the thousands at a time using synthetic detergents, stabilizers, fragrances which can be harsh to your skin.
Like a fine wine, certain processes are worth the wait! Saponification is generally complete within 48 hours once the oils and alkali are mixed. The bars are now cut and while they are now safe to use, it doesn’t mean they should be. Curing is the process of letting the added liquid (water, goat’s milk aloe, etc.) evaporate so that the bars become harder and will provide a better lather. This is best measured by weighing the soap. Once the weight has become consistent, the bar is ready for sale. Without curing, your soap bar is likely to disintegrate on contact with water. Here at Concord Hill we sell no bar before 6 – 8 weeks from cutting to allow for a complete cure.
To extend the life of your bar, keep it out of direct contact with water and let the bar dry between uses.After using your soap, place on a soap saver. This will help your soap last longer.
