CAS 99-76-3: Metilparabeno

Descripción:
Metilparabeno, con el número CAS 99-76-3, es un conservante ampliamente utilizado en cosméticos, productos farmacéuticos y alimentarios. Es un miembro de la familia de los parabenos, que son ésteres del ácido p-hidroxibenzoico. Metilparabeno aparece como un polvo cristalino blanco o un líquido incoloro y es soluble en alcohol y propilenglicol, pero solo ligeramente soluble en agua. Su fórmula química es C8H8O3 y tiene un peso molecular de aproximadamente 152.15 g/mol. Metilparabeno es conocido por sus propiedades antimicrobianas, inhibiendo eficazmente el crecimiento de bacterias y hongos, lo que ayuda a extender la vida útil de los productos. Se reconoce generalmente como seguro por las agencias reguladoras cuando se utiliza dentro de las concentraciones recomendadas. Sin embargo, ha habido cierta controversia respecto a sus posibles efectos disruptores endocrinos, lo que ha llevado a investigaciones y discusiones en curso sobre su seguridad en productos de consumo. En general, Metilparabeno sigue siendo una opción popular para preservar diversas formulaciones debido a su efectividad y bajo perfil de toxicidad.

  • Methyl 4-hydroxybenzoate

    CAS:
    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:
    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
