Propylene glycol (IUPAC name: propane-1,2-diol), according to the National Library of Medicine and Agency for Toxic Substances and Disease Registry, is a synthetic liquid substance that absorbs water.[4] It is labelled an organic compound in chemistry due to its carbon attributes. Its chemical formula is CH3CH(OH)CH2OH. It is a viscous, colourless liquid, which is nearly odourless but possesses a faintly sweet taste. Containing two alcohol groups, it is classed as a diol. It is miscible with a broad range of solvents, including water, acetone, and chloroform. In general, glycols are non-irritating, have very low volatility and very low toxicity.[5]
It is produced on a large scale primarily for the production of polymers. In the European Union, it has the E-number E1520 for food applications. For cosmetics and pharmacology, the number is E490. Propylene glycol is also present in propylene glycol alginate, which is known as E405. Propylene glycol is a compound which is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) under 21 CFR x184.1666 and is also approved by FDA for certain uses as an indirect food additive. Propylene glycol is approved and used as a vehicle for topical, oral and some intravenous pharmaceutical preparations in U.S. and in Europe.
Highly resistant to build-up The materials in contact with the solution are made out of durable SUS316L, and the sample stage has been made fully flat, resulting in a unit that's highly resistant to build-up. |  |
 | Defective products will never slip through A variety of output methods means defective products will never slip through undetected. Recorder output (4-20mA) and RS-232C output can be set-up and linked with an external device for automatic control. |
Compatible with a wide range of temperatures Capable of measurement at temperatures between -15 to 160°C, meaning the unit is perfectly capable of handling CIP and SIP processes. |  |
