Autres noms : 1-2 propanediol (propyl\u00e8ne glycol), 1-3 propanediol<\/p>\n
Le propanediol est un organique compos\u00e9 synth\u00e9tique et un ingr\u00e9dient commun dans les produits de soins tels que les nettoyants, lotions, shampooings, mascara. Il se pr\u00e9sente sous deux formes, soit 1-2 propanediol et 1-3 propanediol.<\/p>\n
Dans les produits de soins personnels, 1-2 propanediol sert de solvant qui r\u00e9duit la viscosit\u00e9 de la composition. Bien qu’il ait des propri\u00e9t\u00e9s hydratantes, il peut irriter la peau et provoquer des dermatites de contact. Il a un point d’\u00e9bullition \u00e9lev\u00e9 de 210\u2103. Il peut \u00eatre pr\u00e9par\u00e9 de mani\u00e8re synth\u00e9tique.
\nEn transformant d’abord, par exemple, l’oxyde d’\u00e9thyl\u00e8ne en 3-hydroxypropionald\u00e9hyde de mani\u00e8re synth\u00e9tique. Plus d’informations sont disponibles sur wikipedia.<\/p>\n
Dans quelques cas, il peut aussi \u00eatre obtenu de mani\u00e8re naturelle. Cela se fait par un processus de fermentation du glyc\u00e9rol avec l’aide de certaines bact\u00e9ries. Il est ensuite converti en 1-3 propandiol.<\/p>\n
L’autre forme 1-3 propanediol agit \u00e9galement comme solvant et r\u00e9duit la viscosit\u00e9 du produit.<\/p>\n
Les deux formes de propanediol sont consid\u00e9r\u00e9es s\u00fbres et ont \u00e9t\u00e9 approuv\u00e9es par EcoCert pour utilisation dans les produits de soins.<\/p>\n
Est-ce un allerg\u00e8ne ?<\/p>\n
Le propandiol est bien tol\u00e9r\u00e9, mais chez les personnes \u00e0 la peau tr\u00e8s sensible, il peut causer des irritations et des \u00e9ruptions cutan\u00e9es.<\/p>\n","protected":false},"excerpt":{"rendered":"
