CAS 99-76-3
:Méthylparabène
Description :
Méthylparabène, avec le numéro CAS 99-76-3, est un conservateur largement utilisé dans les cosmétiques, les produits pharmaceutiques et les aliments. Il fait partie de la famille des parabènes, qui sont des esters de l'acide p-hydroxybenzoïque. Méthylparabène se présente sous la forme d'une poudre cristalline blanche ou d'un liquide incolore et est soluble dans l'alcool et le propylène glycol, mais seulement légèrement soluble dans l'eau. Sa formule chimique est C8H8O3 et il a un poids moléculaire d'environ 152,15 g/mol. Méthylparabène est connu pour ses propriétés antimicrobiennes, inhibant efficacement la croissance des bactéries et des champignons, ce qui aide à prolonger la durée de conservation des produits. Il est généralement reconnu comme sûr par les agences réglementaires lorsqu'il est utilisé dans les concentrations recommandées. Cependant, il y a eu certaines controverses concernant ses effets potentiels de perturbation endocrinienne, ce qui a conduit à des recherches et des discussions en cours sur sa sécurité dans les produits de consommation. Dans l'ensemble, Méthylparabène reste un choix populaire pour préserver diverses formulations en raison de son efficacité et de son faible profil de toxicité.

CAS :<p>Methyl 4-hydroxybenzoate is an organic compound that has been used as a preservative in cosmetics, pharmaceuticals and food. It is a member of the group of compounds known as parabens. Methyl 4-hydroxybenzoate can be prepared by the reaction of p-hydroxybenzoic acid with methyl alcohol. The chemical formula for this substance is CH3CO2C6H4CH3. Methyl 4-hydoxybenzoate (MB) also shows genotoxic activity, which may be due to its ability to form intermolecular hydrogen bonding interactions with DNA or mRNA molecules. The genotoxicity of MB has been tested in vitro using bacterial strains and mammalian cells. MB also exhibits leukemia inhibitory factor (LIF) properties and may be useful for cancer therapy, although it needs more research to confirm this effect.</p>Formule :C8H8O3Degré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :152.15 g/molMethyl 4-hydroxybenzoate - BP grade
CAS :<p>Methyl 4-hydroxybenzoate is an organic chemical compound that is used as a preservative in pharmaceuticals, cosmetics and other industrial applications. Methyl 4-hydroxybenzoate is also used in wastewater treatment plants as a coagulant to remove suspended solids. It is prepared by reacting benzoic acid with methanol. The methyl ester of 4-hydroxybenzoic acid has been shown to induce apoptosis in human cancer cells by inhibiting the ryanodine receptor and controlling the release of calcium from intracellular stores. This chemical also has genotoxic activity which may be due to the reaction between methyl 4-hydroxybenzoate and p-hydroxybenzoic acid. Methyl 4-hydroxybenzoate has a high boiling point, which makes it difficult to dissolve in water. This chemical can be analyzed using plasma mass spectrometry, which separates compounds by their molecular weight and ionizes them before</p>Formule :C8H8O3Degré de pureté :Min. 95%Couleur et forme :White Clear LiquidMasse moléculaire :152.15 g/mol
