Food, Drug or Medicinal Grade Solvents vs Technical or Practical Grade Solvents
Let’s Talk About The Green Scissor Isopropyl Alcohol
The Green Scissor knows that individuals and businesses that process cannabis place trust in their suppliers to properly identify and label the chemical solvents they procure. Manufacturers and suppliers bear the responsibility to identify the grade, regulatory and chemical specifications for the chemical solvent being sold. Additionally, it is the suppliers responsibility to provide safety and analysis data documents when applicable and as required by law. The Green Scissor knows this and takes its supply chain custody role seriously.
It is imperative that everyone in the custody supply chain know and understand the different grades of chemical solvents and their uses.
Isopropyl Alcohol, Like Other Chemical Solvents, Comes in Varying Grades of Purity
The Green Scissor brand Isopropyl Alcohol 99% Gallons = High Grade IPA
Store owners are supplying their customers with a superior IPA when choosing The Green Scissor brand of Isopropyl Alcohol 99% Gallons. The Green Scissor Isopropyl Alcohol Gallons is ACS/USP-N/FCC Reagent Grade. 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*. The ACS provides specific use specifications and procedures for this grade. Additionally the TGS Isopropyl Alcohol Gallons is USP-NF grade which means it is of sufficient purity to meet or exceed requirements of the US Pharmacopeia (USP) and the National Formulary (NF). The USP-NF agencies have combined to set standards for chemical and biological substances. USP/NF grade is acceptable for food, drug, or medicinal use and may be used for most analytical laboratory purposes.*
The purity of the chemical solvent used informs both the process and efficacy of the cannabis extraction or testing assay as well as the impact on human health and safety.
Want to Know More? What Does the 99% Mean?
The percentage figure indicates the portion of the named chemical (ie: isopropyl alcohol) found in the unit. Keep in mind that when analyzing costs for isopropyl alchohol 99%, you’re not paying for the 99% so much as you are paying for what’s NOT in the .01%-1.0%. The remaining portion of the solution may contain varying impurities such as heavy metals, etc. It is imperative that everyone in the custody supply chain know and understand the different grades of chemical solvents and their uses.
Technical Grade is a Lower Grade Solvent Not Approved for Food, Drug or Medicinal Use
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 may contain organic impurities that make it unsuitable for Food, Drug or Analytical use. Technical grade isopropyl alcohol is a ‘lower’ grade that does not need to meet purity standards set by anyone. Technical Grade isopropyl alcohol is suitable for general industrial use: cleaning non-food grade work surfaces and equipment, for use as a solvent for inks, tape head cleaning, electronics, aircraft maintenance, etc. Technical Grade is not pure enough to be offered for food, drug, or medicinal use of any kind. Technical Grade IPA may contain impurities including: acetone, aldehydes, ketones, heavy metals. Know the difference. Know what you are selling to your customers. Know what your customers are using the solvent for.
*Consult the ACS (American Chemical Society) for proper use and application guidelines for all chemical solvents including IPA.
