During the saponification process, the
glycerin forms naturally. Cold saponified soaps are therefore naturally rich in vegetable glycerin, known for its moisturizing, emollient and protective properties.
We sometimes observe in cold saponified soaps, somewhat transparent ribs. Soap makers call them “rivers of glycerin”!
Industrial soaps are made with excess soda (to saponify all the fatty substances), then they are rinsed to remove the remaining soda. During this operation, they also lose their glycerin. These soaps (quite harsh) are more suitable for household use than cosmetic. Cold saponified soaps are made with an excess of fatty substances ( vegetable oils , shea butter , etc.). Once the saponification process is complete, there are therefore unsaponified fatty substances in the soap. It is for this reason that they are called " surgras ".
To make a soap, you need: a fatty substance and an alkaline agent (soda, potash). The chemical reaction between these two components gives rise to soap.
This is called " saponification ".
Cold saponification strives to respect the raw materials. Fats are processed at a maximum of 35°C.
They therefore retain their properties and do not
are not damaged during manufacture .
Industrial soaps are shaped hot
and the fatty substances are raised to temperatures of between 100°C and 130°C.
#4 Zero waste
Each year, 186 million bottles of shower gel are sold in France. With the
shampoos and bubble baths, they generate 16,000 tonnes of packaging and only 40% is recycled (Source: Ademe).
Handmade soap bars often have minimalist packaging (paper or cardboard) and do not generate plastic waste. Preferring soap to shower gel is taking a first step towards zero-waste!
Most cold process soaps do not contain controversial and superfluous products (but this is not always the case). To protect your health, learn to read
the labels where the ingredients are indicated according to the INCI nomenclature (International Nomenclature of Cosmetics Ingredients). At the beginning of the list, we find the majority ingredients, then, those whose quantity is less.
For a soap, the list always starts
by saponified oils (soap): Sodium... "ate".
Entirely biodegradable , cold saponified artisanal soaps do not contribute
not to water pollution and the degradation of ecosystems.
Choosing a handmade soap is making a gesture in favor of the protection of water resources.
Buying cold saponified soap from a craftsman near you helps support the local economy and short circuits . The artisanal soap factories established in the countryside contribute to revitalizing rural areas and it is also this momentum that everyone can support thanks to their consumption choices.
Provided you dry it properly between two uses on a soap dish
which makes it possible to drain the water well, a 100g cold saponified soap makes it possible to carry out
more washes than a 250ml liquid shower gel (especially when used with a shower flower that helps improve its
foaming power). Economical, ecological, respectful of your skin and the environment... Cold saponified soap has it all!
