Metilparabene

Descrizione:
Metilparabene, con il numero CAS 99-76-3, è un conservante ampiamente utilizzato in cosmetici, prodotti farmaceutici e alimentari. È un membro della famiglia dei parabeni, che sono esteri dell'acido p-idrossibenzoico. Metilparabene appare come una polvere cristallina bianca o un liquido incolore ed è solubile in alcol e glicole propilenico, ma solo leggermente solubile in acqua. La sua formula chimica è C8H8O3 e ha un peso molecolare di circa 152,15 g/mol. Metilparabene è noto per le sue proprietà antimicrobiche, inibendo efficacemente la crescita di batteri e funghi, il che aiuta a prolungare la durata dei prodotti. È generalmente riconosciuto come sicuro dalle agenzie di regolamentazione quando utilizzato entro le concentrazioni raccomandate. Tuttavia, ci sono state alcune controversie riguardo ai suoi potenziali effetti dirompenti endocrini, portando a ricerche e discussioni in corso sulla sua sicurezza nei prodotti di consumo. In generale, Metilparabene rimane una scelta popolare per preservare varie formulazioni grazie alla sua efficacia e al basso profilo di tossicità.

  • Methyl 4-hydroxybenzoate

    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>

  • Methyl 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>
