Sodium Ethylparaben

What is Sodium Ethylparaben?

Sodium Ethylparaben is the sodium salt of ethylparaben, a synthetic preservative widely used in cosmetics and personal care products to inhibit the growth of bacteria, yeast, and mold. It functions by disrupting microbial cell membranes and is effective in water-based formulations at concentrations typically ranging from 0.1% to 0.4%. As a paraben ester, it is more water-soluble than its acid form, allowing better incorporation into emulsions and aqueous products.
