Artisanal soap creation
Cold saponification is a chemical reaction done at room temperature where lye and fats (in our case plant oils and butters) react to glycerine and soap.
Saponification ist a total Reaktion, i.e. the Reaktion goes on until one of the two starting products (lye or fats) is exhausted. Usually the ingredients are calculated so there is more fat than what the lye can saponify. Thus creating soaps that provide nourishing and softening properties for your hair and skin.
The majority of plant oils and butter used in saponification contain non-saponifiable parts. Molecules which will not be transformed by the lye and give the soap antioxidant, nourishing, emollient, softening, protective, etc properties.
The naturally contained glycerine adds moisturising properties.
In addition, different plant and mineral powders can be add to create skin and hair loving and beautifying soaps.
The base of all our soaps contains organic copra vegetable oil, which is known and appreciated in saponification for increasing the washing and foaming power of the soaps. Castor oil increases the creaminess and lathering.
Different oils and butters such as babassu, cherry seed, tucuma, cocoa butter, shea butter, plant powders such as althaea powder, flax powder, spirulina and mineral powders such as white clay or yellow clay are added in relation to the anti-oxidant, anti-ageing, calming, protective and moisturising properties they add.
After removal from the mould and before being used, a "cure" period of at least 4 weeks allows the saponification process to be completed and the soap to harden and dry. In general, a longer cure time improves properties such as the soap's longevity and foaming power. The cure time at Hyangsu Cosmetics is between 6 to 8 weeks.
