Residual solvents (methanol): ≤ 100 mg/kg
Class 1 residual solvents (solvents to be avoided)
Class 3 residual solvents (solvents of low toxicity)
Water, oxygen, carbon dioxide, hydrogen, and residual solvents are gettered.
Guidance for industry : Q3C impurities, residual solvents
With respect to the control of residual solvents, it is acknowledged that GC methods for determining residual solvents are generally sensitive, linear, and reproducible.

Previous version: Limits for Residual Solvents in Cannabis Products
Spray drying steps are carried out to remove residual solvents and vinyl stearate.
A complete lab test should also include analyses of residual solvents.
The European (Ph. Eur.) and the US (USP) pharmacopoeias deal with the topic of solvent residues in the respective chapter on “Residual Solvents” (Ph. Eur.
The extraction process also necessitates careful monitoring of solvent residues, rancidity via peroxide values, moisture content, other impurities, and phospholipid content.

Class 3 solvents: Solvents with low toxic potential.
Class 3 solvents: Solvents with low toxic potential
Residual solvent analysis in raw materials and end products
Bitumen and residual solvent are produced from the lower well.
(d) Impurities: Organic and inorganic impurities and residual solvents are included in this category.
A complete lab test should also include analyses of the residual solvents.
Impurities: Organic and inorganic impurities (degradation products) and residual solvents are included in this category.
Classification of Solvents in Pharmaceutical Products, ICH Q3C
The leftover toxic chemicals after the extraction are referred to as residual solvents.
The ICH Q3C guideline on residual solvents should also be consulted, if appropriate.
Prior to encapsulation the LEP device may be heated and placed in a vacuum to remove moisture, air and residual solvents.
Although Cannabis oils are usually concentrated by evaporating the solvents that were used for extraction, this does not completely eliminate residual solvents.
Permissible levels of oils and residual solvents are regulated by the Canadian Coast Guard (1984).
Although Cannabis oils are usually concentrated by evaporating the solvents that were used for extraction, this does not completely eliminate residual solvents.
