CAS 99-76-3

Methylparaben

Beschreibung:

Methylparaben, mit der CAS-Nummer 99-76-3, ist ein weit verbreiteter Konservierungsstoff in Kosmetika, Pharmazeutika und Lebensmitteln. Es gehört zur Familie der Parabene, die Ester der p-Hydroxybenzoesäure sind. Methylparaben erscheint als weißes kristallines Pulver oder als farblose Flüssigkeit und ist in Alkohol und Propylenglykol löslich, aber nur leicht in Wasser löslich. Seine chemische Formel ist C8H8O3 und es hat ein Molekulargewicht von etwa 152,15 g/mol. Methylparaben ist bekannt für seine antimikrobiellen Eigenschaften, die das Wachstum von Bakterien und Pilzen effektiv hemmen, was hilft, die Haltbarkeit von Produkten zu verlängern. Es wird von den Regulierungsbehörden allgemein als sicher anerkannt, wenn es in den empfohlenen Konzentrationen verwendet wird. Es gab jedoch einige Kontroversen über seine potenziellen endokrinen Störungen, was zu laufenden Forschungen und Diskussionen über seine Sicherheit in Verbrauchermärkten geführt hat. Insgesamt bleibt Methylparaben eine beliebte Wahl zur Konservierung verschiedener Formulierungen aufgrund seiner Wirksamkeit und seines niedrigen Toxizitätsprofils.

Methyl 4-hydroxybenzoate

CAS: 99-76-3

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.

Methyl 4-hydroxybenzoate - BP grade

CAS: 99-76-3

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
