CAS 99-76-3
:Metilparabeno
Descrição:
Metilparabeno, com o número CAS 99-76-3, é um conservante amplamente utilizado em cosméticos, produtos farmacêuticos e alimentícios. É um membro da família dos parabenos, que são ésteres do ácido p-hidroxibenzoico. Metilparabeno aparece como um pó cristalino branco ou um líquido incolor e é solúvel em álcool e propilenoglicol, mas apenas ligeiramente solúvel em água. Sua fórmula química é C8H8O3 e tem um peso molecular de aproximadamente 152,15 g/mol. Metilparabeno é conhecido por suas propriedades antimicrobianas, inibindo efetivamente o crescimento de bactérias e fungos, o que ajuda a prolongar a vida útil dos produtos. É geralmente reconhecido como seguro pelas agências reguladoras quando usado dentro das concentrações recomendadas. No entanto, houve alguma controvérsia em relação aos seus potenciais efeitos disruptores endócrinos, levando a pesquisas e discussões em andamento sobre sua segurança em produtos de consumo. No geral, Metilparabeno continua sendo uma escolha popular para preservar várias formulações devido à sua eficácia e baixo perfil de toxicidade.

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>Fórmula:C8H8O3Pureza:Min. 95%Cor e Forma:SolidPeso molecular: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>Fórmula:C8H8O3Pureza:Min. 95%Cor e Forma:White Clear LiquidPeso molecular:152.15 g/mol
