Research and innovation on “products”

<<  <  >  >> 

In spite of the 1870 defeat and the horror of the Great War, science progressed and conquered people’s minds. Notions such as chemical equations [1], optical isomerism [2], bacteria, superficial tension [3], emulsification, synthetic coloring agents, etc., allowed new, more sophisticated products to come to light. In 1879, Roger et Gallet, using the so-called “cauldron” method, invented the first round soap. Around 1900, glycerin, a by-product of saponification discovered by Chevreul, was added to creams with alkaline stearates – which, dry the skin. Creams were protected from bacterial contaminations with the reinforcement of specific essential oils whose antimicrobial properties had recently been discovered.

×Chemical equation: the representation of the chemical reaction between two molecules.

 

×Optical isomerism: refers to the fact that two molecules are the image of one another in a plane mirror and are non-superimposable. In 1848, Pasteur was the first to separate two optical isomers.
×Surface tension: force existing at the interface of two different milieus and governing their adhesion.
