Application of High Purity Sodium Methylparaben CAS 5026-62-0 with best price
Methyl 4-hydroxybenzoate has antimicrobial characteristics and is used as preservative in pharmaceutical formulations and cosmetics. It can be combined with other parabens like propyl 4-hydroxybenzoate or ethyl 4-hydroxybenzoate. The sodium salt provides improved solubility in water compared to standard methyl 4-hydroxybenzoate.
