Butylparaben Sodium

Butylparaben Sodium (CAS 36457-20-2), also known as Sodium Butylparaben, is the water-soluble sodium salt form of butylparaben; a broad-spectrum antimicrobial preservative.

Where is Butylparaben Sodium used?

• Cosmetics and personal care: protects water-containing lotions, shampoos and liquid cleansers against bacterial and fungal contamination throughout shelf life
• Pharmaceuticals: preservative in oral suspensions, topical creams and multi-dose injectable preparations
• Food: preservation of beverages, sauces and other high-moisture products
• It is also used with other parabens or preservative systems for broader antimicrobial coverage at lower individual concentrations.

Good to know: Its enhanced solubility compared to the parent ester makes it the preferred form for aqueous-based formulations.
