Description and Uses

Butylparaben is an antimicrobial agent used in pharmaceutical suspensions. It is act by inhibiting DNA, RNA, and enzymes (eg, ATPase and phosphotransferase) synthesis. Butylparaben may be used alone or with other parabens, chiefly methylparaben and/or propylparaben, in medications. It is common in many liquid and solid (gel cap) OTC products such as Tylenol, Drixoral, Maalox, and Mylanta. Unfortunately, butylparaben concentrations were seldom identified for OTC or prescription products. No attempt was made to identify butylparaben-containing dietary supplements.

preservative in many creams, lotions, ointments and other cosmetics, foods (salad dressings, mayonnaise, spiced sauces, mustard, frozen dairy products, baked products), pharmaceutical preparations and dentifrices. It is active against molds, fungi and yeasts, but less active against bacteria. ICU.
