Cannabis extracts degrade through three distinct mechanisms: THCa nucleation (shatter sugaring at supersaturation ratios above 1.3x, onset within 48-72 hours above 25C when THCa exceeds 65%), oxidative conversion (THC to CBN at 0.5-2.0% per month at 25C with light, 0.08-0.15% per month at 4C in dark), and terpene volatilization (myrcene half-life 8-12 weeks at 25C, [...]
Cannabis filtration media splits into two functional classes: depth filtration (celite, perlite, filter paper) that removes particulates by size exclusion at 1-25 micron pore ratings, and adsorptive chromatography media (activated carbon, bentonite clay, silica gel, alumina, magnesium silicate) that removes contaminants by chemical interaction. Activated carbon adsorbs 85-95% of color bodies but strips 8-15% of [...]
Cannabis pesticide remediation removes chemical residues from contaminated extracts using targeted adsorption: activated carbon grabs nonpolar organics like myclobutanil (log P 2.89) and bifenazate (log P 3.40) through van der Waals attraction in micropores sized 8-20 angstroms. Bentonite clay captures polar and cationic pesticides like daminozide (log P -0.29) through ion exchange at interlayer sites. [...]
The Short Answer The catalyst you choose determines which cannabinoid you make, how fast you make it, and how much cleanup you need afterward. BF3 etherate pushes CBD toward delta-9-THC with 70-85% conversion in 1-3 hours at 60-80C. pTSA and CSA favor delta-8-THC through a longer ring closure pathway, hitting 80-95% conversion in 4-12 hours [...]
Every state with legal cannabis has different extraction licensing requirements. Different agencies, different fees, different facility standards, different timelines. This is the only guide that compiles them with the numbers that matter: application costs, annual license fees, facility classification requirements, allowed extraction methods, and the specific compliance details that determine whether your lab application gets [...]
What is CBD Isomerization? CBD isomerization is an acid-catalyzed rearrangement that converts cannabidiol into delta-9 THC, delta-8 THC, or other THC isomers. The reaction uses a Lewis or Bronsted acid catalyst (p-toluenesulfonic acid, boron trifluoride etherate, sulfuric acid, or others) to protonate the CBD molecule and trigger ring closure at the cyclohexene ring. The resulting [...]
Every CBD isomerization reaction produces byproducts. That is not a failure. That is thermodynamics. The acid catalyst does not care which ring closure pathway the molecule takes. It offers activation energy, and the CBD molecule responds by forming a distribution of products: delta-9 THC, delta-8 THC, iso-THC isomers, and degradation compounds that show up as [...]
What is degumming in cannabis processing? Degumming is the step that removes phospholipids and related polar lipids from crude cannabis oil before distillation. If winterized crude still darkens hard in the still, leaves stubborn residue on hot surfaces, or produces a distillate that tastes flatter than it should, degumming is usually the missing step. Most [...]
Your nano emulsion separated overnight. Or it was cloudy when it should have been clear. Or the particle size analyzer came back at 350nm after your sonicator ran for 20 minutes. Every formulator hits these walls. The difference between the ones who fix them and the ones who dump batches comes down to understanding which [...]
Most Cannabis Tinctures Fail Before the First Drop Hits Your Tongue The problem is never the ethanol. The problem is decarboxylation control, extraction efficiency, and the dosing math that turns a good extraction into a reliable medicine. A tincture that varies 40% batch to batch is not a product. It is a liability. Cannabis tinctures [...]
