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.
