Apr\u00e8s la fabrication du savon, Mme Ludivine BUCHIN, la g\u00e9rante de cette entreprise, nous a expliqu\u00e9 les \u00e9tapes suivant la fabrication,&nbsp;\u00e0 savoir la d\u00e9coupe, le s\u00e9chage et l\u2019emballage. <\/p>\n\n\n\n<p>Dans cette petite entreprise Mme BUCHIN fonctionne de fa\u00e7on artisanale avec comme m\u00e9thode la saponification \u00e0 froid&nbsp;: un m\u00e9lange de corps gras (huiles v\u00e9g\u00e9tales, beurres, etc\u2026) et de soude dans des quantit\u00e9s adapt\u00e9es pour que ces substances r\u00e9agissent entre elles sans chauffage. Ceci contribue \u00e0 la r\u00e9alisation de savons doux pour la peau.&nbsp; <br><br>Plusieurs informations compl\u00e9mentaires ont \u00e9galement \u00e9t\u00e9 apport\u00e9es, concernant par exemple l\u2019aspect r\u00e9glementaire et l\u2019\u00e9tiquetage. <br>Cette visite a \u00e9t\u00e9 prolong\u00e9e en janvier 2023. Mme BUCHIN est alors venue au lyc\u00e9e Paul Constans pour un TP de formulation avec les \u00e9tudiants de 1<sup>\u00e8re<\/sup> ann\u00e9e. Cela a \u00e9t\u00e9 l\u2019occasion de discuter de la mise au point d\u2019un cahier des charges, objet r\u00e9guli\u00e8rement travaill\u00e9 en formulation au lyc\u00e9e. <br><\/p>\n\n\n\n<p>Au final, cet \u00e9change a \u00e9t\u00e9 fructueux. En effet, il a permis de d\u00e9couvrir l\u2019exercice de la formulation en savonnerie artisanale tout en permettant \u00e0 Mme BUCHIN d\u2019\u00e9tayer sa pratique \u00e0 l\u2019aide de m\u00e9thodes sp\u00e9cifiques \u00e9tudi\u00e9es au laboratoire de formulation du lyc\u00e9e.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7
