PROPYLENE GLYCOL USES, SPECIFICATIONS, and WHERE TO BUY

PROPYLENE GLYCOL: COMMON USES, SPECIFICATIONS, and WHERE TO BUY 

Propylene glycol

Propylene glycol is a near odorless, clear, colorless, viscous liquid,  and which possesses a faintly sweet taste. The chemical formula is CH3CH(OH)CH2OH.  

Propylene glycol, also known by the abbreviation, PG,  is widely used since it is miscible water and a  broad range of other solvents, acetone, and chloroform. Like most glycols, PG, in general is non-irritating and has low  volatility. 

The CAS number for Propylene Glycol is 57-55-6

PG is major industrial chemical and it is produced on a large scale primarily for the production of polymers, and  as a very useful intermediate for other chemicals. In 2019 nearly 2 million metric tons were produced.  

It is used in all kinds of commerical, industrial and even sme home uses. PG is  used in making aircraft deicing fluids, and also has uses in applications like home and auto products, and since it is considered GRAS (see below) also in food products like ice cream. Currently, most propylene glycol is made by reacting propylene oxide with water.

In the US Propylene glycol is a compound which is listed as GRAS, defined as generally recognized as safe, by the US FDA/ Food and Drug Administrations under 21 CFR x184.1666, and is also approved by the 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 the U.S. and in Europe.

Make sure that the grade you are buying is suitable for the applications you will use it in . For example, you do not buy a technical grade propylene glycol for an application in a food or a drink for example. If you are using propylene glycol where it will be used as a food ingredient or in a beverage you will need to source a USP food grade propylene glycol. Typically food grade PG  will be slightly more  expensive than a technical grade used in a paint formulation for example. Always request a Certificate of Analysis for your chemicals and ingredients to make sure you will be receiving what you have requested and the best material for your application and usage. 

Don't make the mistake of buying another glycol with a similar name either. Do not buy di-propylene glycol thinking it is the same as propylene glycol. These are not the same chemical and can not be used interchangeably. 

Check Level 7 Chemical for the very best propylene glycol. Level 7 Chemical sells high quality propylene glycol food grade, and can also get a technical grade upon request. Additionally we can also help with custom blends of PG and DI water.

N-Methylpyrrolidone (NMP) uses, applicaitons, and sourcing

N-Methylpyrrolidone (NMP) N-Methylpyrrolidone is a colorless to slightly yellow liquid with a mild amine odor. It is very versatile since is it miscible with water and various solvents. N-Methylpyrrolidone, also known by the synonym NMP, is a  versatile, effective solvent that in many applications replaces dangerous solvents and solvents that are or were ozone depleting. It  used in numerous commercial/industrial applications as a co-solvent with water, alcohols and other organic substances.  used as a cleaner and degreaser and in many other applications. It is often used in specialty resins, stripping epoxy, as a pigment dispersant, plastics, textiles,  agrochemicals. In the electronics/ microelectronics industry specifically it is often used as a process solvent for  cleaning silicon wafers, removing marker dyes and soldering flux residues from circuit boards. One advantage of NMP   is that it is not on the Hazardous Air Pollutants (HAPs) list of the...

Citric Acid Fine Granular USP Food Grade

 CITRIC ACID FINE GRANULAR USP FOOD GRADE Citric Acid fine granular, is a  widely used weak organic acid. It is  found in  many foods nad beverages and in many commercial and industrial processes and technical applications. In food, it is popular since it adds a 'sour' taste or "ZING"  to products, especially candies and confectionaries.  In  chemical processes it is used as a weak acid, and to lower pH.  Around the home citric acid is used in cleaners as a weak chelate or to reduce the pH in cleaners where acidity adds the ability to help eliminate surface grime and  mineral deposits for example.  Typical Uses  of citric acid, both granular and in solution are: Food, Candy, Confectionary Beverages (pH) Water and wastewater pH adjustments Water conditioning Pet/Animal Feed Oil Well Cementing pH Control Chelate The CAS number is  77-92-9 Synonyms: of citric acid are , sour salt, and just "c itric" Appearance: White Crystall...
