Description

Butylparaben Sodium (CAS 36457-20-2 ), also known as Sodium Butylparaben, is the water-soluble sodium salt form of butylparaben used as a broad-spectrum antimicrobial preservative. Its enhanced solubility compared to the parent ester makes it the preferred form for aqueous-based formulations across personal care, pharmaceutical, and food applications. In cosmetics and personal care, it protects water-containing formulations such as lotions, shampoos, and liquid cleansers against bacterial and fungal contamination throughout shelf life. Pharmaceutical manufacturers incorporate it as a preservative in oral suspensions, topical creams, and multi-dose injectable preparations where aqueous compatibility is critical. Food-grade applications include preservation of beverages, sauces, and other high-moisture products where microbial stability must be maintained without affecting taste or clarity. It is also used in combination with other parabens or preservative systems to achieve broader antimicrobial coverage at lower individual concentrations for industrial use. Butylparaben Sodium is supplied as a white crystalline powder or fine granules. It is available in pharmaceutical grades conforming to USP and BP specifications. Technical and food-grade designations are available depending on the target application. Packaging typically ranges from kilogram-scale bags to bulk quantities for industrial procurement.
