\"Saponification\"<\/a>
Saponification<\/figcaption><\/figure>\n

In 1791, Nicolas Leblanc, a French chemist, invented caustic soda from seawater salt. In his factory in Marseille, a revolution had just taken place!<\/p>\n\n

The Master Soap Makers of Marseille \u2013 who have acquired a particular know-how by producing olive oil-based soap, as in Aleppo (Syria) or Gallipoli (Italy) \u2013 gradually improved their processes: thus, began modern \u201cMarseille\u201d saponification.<\/p>\n\n

Unlike cold production, it is based essentially on the use of noble oils mixed with soda and cooked in a soap factory. This original 4-step process was codified by decree as early as 1812…and more recently in 2003. To meet consumer expectations, Provendi has developed liquid Marseille soap.<\/p><\/blockquote>\n","protected":false},"featured_media":1956,"template":"","class_list":["post-2058","timeline","type-timeline","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\n1791 — Laboratoire Provendi<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/provendi.fr\/en\/timeline\/1791\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"1791 — Laboratoire Provendi\" \/>\n<meta property=\"og:description\" content=\"In 1791, Nicolas Leblanc, a French chemist, invented caustic soda from seawater salt.
