\n\n \n

\n Achat de Glabridin 90% : Peut-on commander sans un autre essai de formulation ?\n <\/h1>\n\n \n

\n Un devis indique \u00ab Glabridin 90% \u00bb. La mati\u00e8re premi\u00e8re approuv\u00e9e indique \u00e9galement 90%. Les achats peuvent-ils passer la commande sans un autre essai de formulation ?\n <\/p>\n

\n L'analyse correspond. Le grade peut ne pas correspondre.<\/strong>\n <\/p>\n

\n Huatai fournit des grades 90% solubles dans l'alcool et compatibles avec l'huile. Un remplacement peut \u00eatre r\u00e9alisable, mais le seul pourcentage n'est pas suffisant pour l'approuver<\/span>.\n <\/p>\n\n \n

\n V\u00e9rifier ce que la formule existante utilise r\u00e9ellement\n <\/h2>\n

\n Supposons qu'une formule contienne 0,2 % d'un mat\u00e9riau analys\u00e9 \u00e0 90 % de Glabridin par poids. Son apport actif calcul\u00e9 est de 0,18 %. Un remplacement avec la m\u00eame analyse v\u00e9rifi\u00e9e bas\u00e9e sur le poids fournirait la m\u00eame quantit\u00e9 th\u00e9orique. Ce calcul ne dit rien sur la mani\u00e8re dont il entre dans la formule.\n <\/p>\n

\n Examiner les instructions de production :<\/strong> La poudre actuelle est-elle pr\u00e9-dissoute dans un solvant ? Dispers\u00e9e dans l'huile ? Ajout\u00e9e avant l'\u00e9mulsification ou pendant le refroidissement ?\n <\/p>\n

\n Ces d\u00e9tails appartiennent \u00e0 une demande de renseignements sur la poudre de glabridine. Sans eux, deux fournisseurs peuvent proposer des mat\u00e9riaux avec la m\u00eame analyse mais des exigences de traitement diff\u00e9rentes. V\u00e9rifiez \u00e9galement ce que \u00ab 90% \u00bb repr\u00e9sente. Une analyse quantitative et un pourcentage de surface de pic HPLC ne doivent pas \u00eatre automatiquement consid\u00e9r\u00e9s comme \u00e9quivalents.<\/strong> (Note : la poudre de Glabridin de haute puret\u00e9 appara\u00eet blanche, mais le comportement de dissolution varie selon la formulation).\n <\/p>\n\n \n

\n \u00ab Soluble dans l'huile \u00bb n\u00e9cessite une condition de test\n <\/h2>\n

\n Feng et al. (2017) ont mesur\u00e9 la solubilit\u00e9 \u00e0 l'\u00e9quilibre du Glabridin dans plusieurs solvants et ont trouv\u00e9 des diff\u00e9rences substantielles entre les milieux. Leurs r\u00e9sultats n'\u00e9tablissent pas comment un grade commercial 90% se comporte dans une huile cosm\u00e9tique.\n <\/p>\n

\n Le catalogue de Huatai d\u00e9crit un grade 90% soluble dans l'huile et pr\u00e9sente des observations de microscopie et d'apparence en phase huileuse. Dans cet article, \u00ab dispersible dans l'huile \u00bb d\u00e9crit son incorporation pr\u00e9vue dans les syst\u00e8mes huileux. La proportion dissoute ou dispers\u00e9e doit \u00eatre \u00e9valu\u00e9e dans les conditions r\u00e9elles d'utilisation.\n <\/p>\n

\n Une apparence uniforme seule ne prouve pas une dissolution compl\u00e8te.<\/strong> Avant d'accepter la description d'un fournisseur, demandez quel milieu a \u00e9t\u00e9 test\u00e9, \u00e0 quelle concentration et temp\u00e9rature, et comment le r\u00e9sultat a \u00e9t\u00e9 \u00e9valu\u00e9.\n <\/p>\n\n \n

\n Sp\u00e9cification d'achat\n <\/h2>\n

\n Le COA identifie les r\u00e9sultats des lots. Les instructions de traitement expliquent comment le mat\u00e9riau est cens\u00e9 \u00eatre utilis\u00e9. Demandez les deux pour confirmer les d\u00e9tails suivants :\n <\/p>\n \n \n \n \n \n \n \n \n \n \n

\n S'agit-il d'un remplacement direct ou d'un processus r\u00e9vis\u00e9 ?\n <\/h2>\n
    \n
  • Si l'objectif est un remplacement direct :<\/strong> Comparer le mat\u00e9riau propos\u00e9 dans le cadre du processus existant lorsque cela est techniquement appropri\u00e9.<\/li>\n
  • S'il n\u00e9cessite un autre solvant\/une autre \u00e9tape d'ajout :<\/strong> \u00c9valuer cela s\u00e9par\u00e9ment comme un processus r\u00e9vis\u00e9. Il peut toujours \u00eatre commercialement utile, mais il n'a pas pass\u00e9 le m\u00eame test qu'un remplacement direct.<\/li>\n <\/ul>\n

    \n Utiliser le m\u00eame apport actif calcul\u00e9 pour la comparaison. V\u00e9rifier la formule apr\u00e8s fabrication, apr\u00e8s refroidissement et tout au long du programme de stockage pr\u00e9vu (y compris l'inspection des particules, la s\u00e9dimentation et la distribution des actifs).\n <\/p>\n

    \n L'apparence et la stabilit\u00e9 chimique n\u00e9cessitent des v\u00e9rifications s\u00e9par\u00e9es.<\/strong> La r\u00e9tention de Glabridin doit \u00eatre mesur\u00e9e avec une m\u00e9thode analytique adapt\u00e9e \u00e0 la formule finie. Le catalogue de Huatai montre des observations jusqu'au jour 7 pour son grade compatible avec l'huile. Ce sont des observations rapport\u00e9es par le fournisseur, pas une pr\u00e9diction de la dur\u00e9e de conservation du produit fini.\n <\/p>\n\n \n

    \n Comparer le co\u00fbt apr\u00e8s incorporation\n <\/h2>\n

    \n Lors de l'achat de poudre de glabridine en vrac, le prix indiqu\u00e9 au kilogramme n'est qu'une partie de la comparaison. Demandez-vous :\n <\/p>\n

    \n Un grade n\u00e9cessite-t-il un solvant suppl\u00e9mentaire ? Un r\u00e9cipient de pr\u00e9paration s\u00e9par\u00e9 ? Un m\u00e9lange plus long ? Changer le processus n\u00e9cessiterait-il un autre lot pilote ?\n <\/p>\n

    \n Inclure ces \u00e9l\u00e9ments le cas \u00e9ch\u00e9ant. Un grade plus cher doit d\u00e9montrer une diff\u00e9rence utile dans la formule pr\u00e9vue ; un grade moins cher doit r\u00e9pondre aux crit\u00e8res d'acceptation convenus.\n <\/p>\n

    \n Pour un devis :<\/strong> Fournir la sp\u00e9cification actuelle, le type de formule, le taux d'ajout cible, la quantit\u00e9 command\u00e9e et la destination de livraison. Inclure la proc\u00e9dure d'incorporation existante si la demande concerne un remplacement. Huatai peut fournir des sp\u00e9cifications sp\u00e9cifiques aux grades et des \u00e9chantillons de comparaison. Un code produit ou un COA expurg\u00e9 aide \u00e0 identifier le mat\u00e9riau \u00e0 \u00e9valuer.\n <\/p>\n\n \n

    \n FAQ\n <\/h2>\n \n
    \n Deux grades 90% peuvent-ils \u00eatre utilis\u00e9s au m\u00eame taux d'ajout ?<\/strong>\n

    Ils peuvent fournir le m\u00eame apport actif calcul\u00e9 si les deux analyses sont comparables et bas\u00e9es sur le poids. Leur traitement et leurs performances en formule doivent toujours \u00eatre v\u00e9rifi\u00e9s.<\/p>\n <\/div>\n \n

    \n Le Glabridin soluble dans l'alcool peut-il \u00eatre utilis\u00e9 dans une \u00e9mulsion ?<\/strong>\n

    Potentiellement, via un syst\u00e8me de solvant appropri\u00e9. La compatibilit\u00e9 doit \u00eatre v\u00e9rifi\u00e9e apr\u00e8s incorporation, dilution, refroidissement et stockage.<\/p>\n <\/div>\n \n

    \n Un grade dispersible dans l'huile n\u00e9cessite-t-il une pr\u00e9-dissolution ?<\/strong>\n

    Suivre les instructions pour le grade sp\u00e9cifique. La dispersion directe et la pr\u00e9-dissolution sont des proc\u00e9dures diff\u00e9rentes et doivent \u00eatre enregistr\u00e9es en cons\u00e9quence.<\/p>\n <\/div>\n \n

    \n Qu'est-ce qui doit accompagner un \u00e9chantillon de remplacement ?<\/strong>\n

    Demander la sp\u00e9cification, le COA du lot d'\u00e9chantillon, les informations sur la composition, la FDS et les instructions de traitement. Confirmer que les commandes en vrac ult\u00e9rieures suivront la m\u00eame sp\u00e9cification de grade convenue.<\/p>\n <\/div>\n\n \n
