About Propylene glycol, 99%

Propylene glycol is an aroma chemical (Synthesis grade) carrying the CAS registry number 57-55-6 at a purity of 99%. Its molecular formula is C3H8O2 and its molecular weight is 76.09 g/mol. Its systematic (IUPAC) name is propane-1,2-diol. It is also known as 1,2-Propanediol or 1,2-Propylene glycol.

It is supplied as a colourless liquid. Literature values give a boiling point of 187 °C. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include flavour formulation, fragrance compounding and aroma research. Our customers for this product work in food and beverage processing and cosmetics and personal care.

Standard pack sizes are 500 mL, 5 L and 215 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
