Pharmaceutic aid.

The Uses of Sodium methylparaben

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.

Flammability and Explosibility

Non flammable

Contact allergens

This substance is one of the parabens family. Parabens are esters formed by p-hydroxybenzoic acid and an alcohol. They are largely used as biocides in cosmetics and toiletries, medicaments, or food. They have synergistic power with other biocides. Parabens can induce allergic contact dermatitis, mainly in chronic dermatitis and wounded skin.
