CAS 99-76-3: 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.

Prodotto fuori produzioneMethyl 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.Formula:C8H8O3Purezza:Min. 95%Colore e forma:SolidPeso molecolare:152.15 g/mol
