Soap-making

The history of soap

The history of soap goes back to thousands years ago. The Sumerians and the Egyptians made it as a paste with animal fat and potash. At the time, soap was used for purposes other than daily hygiene: treating skin diseases, bleaching hair and laundry.

It was not until the 2^nd century AD that the Romans started using soap for personal hygiene. Then, over the years, the uses of soap and saponification recipes diversified.

The Arabs were able to obtain firmer soap by using the ashes of sea plants that contain lye. Their know-how travelled from the Middle East to the Mediterranean area: Spain, Italy and especially France. And that is how the harbour of Marseille became the main transiting hub for soap!

The designation “Marseille Soap” refers to a revolutionary manufacturing process. Animal fat was substituted with olive oil from the Marseille area, and this made the soap firmer.

Despite the modernity of the soap industry, the basis of saponification has never changed. The process consists in combining lipids or fats with alkaline agents. There are two types of soaps :

LYE SOAP

Solid soap obtained by mixing vegetable oil with sodium hydroxide.

POTASH SOAP

Liquid and/or paste soap obtained by mixing vegetable oil with potassium hydroxide or potash.

Laboratoire Sandralex is proud of this thousand-year-old heritage which we are still putting to good use today! In order to adapt to the needs of today’s market, we offer soap products in various forms.

You can choose between raw materials such as soap pellets and liquid soap concentrates, or finished products such as paste soaps and transparent or liquid soaps.

Our products are manufactured with natural ingredients. Depending on the criteria in your specifications, the ingredients used may also be sourced from organic farming, which is currently in high demand !

Soap noodles

Conventional palm oil-free range
Our soap noodles are essentially formulated with copra, sunflower or olive oil. As palm oil is responsible for the deforestation caused by the intensive monoculture of palm trees, we chose to limit its use in our formulas as much as possible in order to protect the biodiversity.
ECOCERT/COSMOS certified
We produce soaps using a base of several vegetable oils: sunflower, copra or olive oil. Most of Laboratoire Sandralex soap noodles are of natural and vegetable origin and are COSMOS Natural and COSMOS Organic certified, two renowned certifications.
