Uses
Sodium Methylparaben has antimicrobial characteristics and is used as preservative in pharmaceutical formulations and cosmetics.
Sodium Methylparaben 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.
Contact allergens
Sodium Methylparaben 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.
