Butylene glycol occurs as a clear, colorless, viscous liquid with a sweet flavor and bitter aftertaste. Synonyms: Butane-1,3-diol; 1,3-butylene glycol; b-butylene glycol; 1,3-dihy- droxybutane; methyltrimethylene glycol. CAS No. 107-88-0. Product ID: PE0400. Molecular formula: C4H10O2. Mole weight: 90.14. Category: Preservatives; Humectants; Solvents. Product Keywords: Pharmaceutical Excipients; Other Materials; Humectants; Butylene Glycol; PE0400; 3XUS85K0RA; 107-88-0; 107-88-0. UNII: 3XUS85K0RA. Chemical Name: 1,3-Butanediol. Grade: Pharmceutical Excipients. Dosage Form: Transdermal patches;topical gel patches/medicated plasters. Stability and Storage Conditions: Butylene glycol is hygroscopic and should be stored in a well-closed container in a cool, dry, well-ventilated place. When heated to decomposition, butylene glycol emits acrid smoke and irritating fumes. Source and Preparation: Butylene glycol is prepared by catalytic hydrogenation of aldol using Raney nickel. Applications: Butylene glycol is used as a solvent and cosolvent for injectables.It is used in topical ointments, creams, and lotions,and it is also used as a vehicle in transdermal patches. Butylene glycol is a good solvent for many pharmaceuticals, especially estrogenic substances.In an oil-in-water emulsion, butylene glycol exerts its best antimicrobial effects at 8% concentration.Higher concentrations above 16.7% are required to inhibit fungal
