Where Does IPA Come From?
Isopropyl alcohol, like many other chemical solvents, is made from fossil fuels: petroleum, natural gas and coal. Isopropyl Alcohol, also known as Isopropanol, is used in a wide array of industries and has many applications. The application informs the grade. Not all isopropanol is alike. In a nutshell, the grade denotes the purity of the chemical.
Know Your Grades and Be Responsible: Many isopropyl alcohol brands are now being sold into the hydroponics market that are Technical Grade. Buyer beware: these products are often mis-labeled and/or mis-marketed as qualifying for uses that they do not qualify for. Technical Grade Isopropanol contains organic impurities that make it unsuitable for Food or Drug use. Technical grade isopropyl alcohol is a ‘lower’ grade that does not need to meet purity standards set by anyone but does meet basic Mil Specs for use as a solvent in aircraft maintenance and similar uses.
Chemical Solvent Grades Explained
The US Pharmacopeia (USP) and the National Formulary (NF) agencies have combined to set standards for chemical and biological substances and provide guidelines for the proper use and applications of isopropanol and other chemicals.
ACS grade meets or exceeds purity standards set by the American Chemical Society (ACS) and constitutes a grade to be used for procedures requiring high purity. Additionally the The Green Scissor Isopropyl Alcohol Gallons is USP-NF grade and of sufficient purity to meet or exceed requirements of the US Pharmacopeia (USP) and the National Formulary (NF). USP-NF grade is acceptable for food, drug, or medicinal use and may be used for most analytical laboratory purposes. FCC reflects additional food grade status.
The seven most common grades for chemical solvents from highest to lowest grade/purity are as follows: USP-NF grade, FCC grade, ACS grade, Reagent grade, Laboratory grade, Purified grade, Technical grade. Take note: Technical Grade is the LOWEST grade.
