ZLEY\u00ae BRC-WS : un m\u00e9lange \u00e0 base de 4-butylr\u00e9sorcinol destin\u00e9 aux formules \u00e9claircissantes<\/h2>
\"M\u00e9lange
<\/figcaption><\/figure>

ZLEY\u00ae BRC-WS est un m\u00e9lange d'ingr\u00e9dients sp\u00e9cialement formul\u00e9 contenant 4-butylr\u00e9sorcinol (CAS 18979-61-8)<\/strong>. V\u00e9rifier l'identit\u00e9 par rapport \u00e0 la version actuelle Fiche technique ZLEY\u00ae BRC-WS<\/a> et PubChem<\/a>.<\/p>

Que contient ce m\u00e9lange ?<\/h3>

La fiche technique ZLEY\u00ae publi\u00e9e mentionne l'eau, le propanediol, l'hydroxypropylcyclodextrine, le 4-butylr\u00e9sorcinol et le bisulfite de sodium. Elle pr\u00e9cise 12,51 TP3T \u00b1 1,01 TP3T 4-butylr\u00e9sorcinol<\/strong> dans le m\u00e9lange fourni. Il s'agit d'un mat\u00e9riau diff\u00e9rent de la poudre de 4-butylr\u00e9sorcinol pure : le pourcentage de BRC-WS ajout\u00e9 \u00e0 une formule ne correspond pas au pourcentage de la mol\u00e9cule active.<\/p>
V\u00e9rification de l'acheteur<\/th>Pourquoi est-ce important ?<\/th><\/tr>
Contenu actif<\/td>Calculez la concentration active \u00e0 partir du dosage effectu\u00e9 sur le lot concern\u00e9.<\/td><\/tr>
Composition du support<\/td>V\u00e9rifiez la compatibilit\u00e9 avec la formule compl\u00e8te et les exigences en mati\u00e8re d'\u00e9tiquetage.<\/td><\/tr>
Aspect et pH<\/td>Comparez le lot livr\u00e9 avec le certificat d'analyse (COA) et la fiche technique (TDS) en vigueur.<\/td><\/tr>
Stabilit\u00e9 du produit fini<\/td>Tester la couleur, la clart\u00e9, le conditionnement et les performances dans les conditions de stockage applicables.<\/td><\/tr><\/tbody><\/table>

Le niveau d'utilisation ne constitue pas une limite de s\u00e9curit\u00e9 universelle<\/h3>

La fiche technique publi\u00e9e sugg\u00e8re une 1\u201361 : taux d'ajout de TP3T dans le m\u00e9lange<\/strong>. Il s'agit d'une recommandation de formulation \u00e9manant du fournisseur, et non d'une limite r\u00e9glementaire universelle ni d'une garantie quant \u00e0 la s\u00e9curit\u00e9 du produit fini. L'ancien tableau indiquant les \u201c concentrations maximales de s\u00e9curit\u00e9 \u201d par type de produit ne disposait pas d'une source v\u00e9rifiable et a donc \u00e9t\u00e9 supprim\u00e9. Choisissez une concentration apr\u00e8s avoir proc\u00e9d\u00e9 \u00e0 une analyse r\u00e9glementaire sp\u00e9cifique au march\u00e9, \u00e0 une \u00e9valuation de l'exposition et \u00e0 des essais sur la formulation finale.<\/p>

Le fournisseur fiche de donn\u00e9es de s\u00e9curit\u00e9<\/a> signale les risques d'irritation li\u00e9s \u00e0 la manipulation de la mati\u00e8re premi\u00e8re concentr\u00e9e. Cela ne permet pas de d\u00e9terminer le profil de s\u00e9curit\u00e9 ou d'irritation de chaque produit fini dilu\u00e9 ; tant la manipulation de la mati\u00e8re premi\u00e8re que l'utilisation du produit fini doivent faire l'objet d'une \u00e9valuation distincte. De m\u00eame, les all\u00e9gations relatives \u00e0 une meilleure p\u00e9n\u00e9tration, \u00e0 une lib\u00e9ration prolong\u00e9e ou \u00e0 des performances cliniques sup\u00e9rieures doivent s'appuyer sur des donn\u00e9es sp\u00e9cifiques \u00e0 la qualit\u00e9 et \u00e0 la formule finale du produit.<\/p>

Consultez le Page produit ZLEY\u00ae BRC-WS<\/a> pour le m\u00e9lange commercialis\u00e9. Si vous le comparez \u00e0 la poudre pure, consultez notre Guide de formulation du 4-butylr\u00e9sorcinol<\/a> et demandez les fiches techniques (TDS), les fiches de donn\u00e9es de s\u00e9curit\u00e9 (SDS) et les certificats d'analyse (COA) par lot pour les deux qualit\u00e9s. Veuillez envoyer votre format et votre march\u00e9 cible \u00e0 services@zleygroup.com<\/a> La discussion commence donc par les sp\u00e9cifications pertinentes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
