About CBD Extraction in the Lab
Cannabis is big business. More and more states are passing medical use laws and the recreation-al cannabis market isn't far behind. Medical use is especially targeted on cannabidiol (CBD) extracts while extracts of tetrahydrocannabinol (THC) have led the leisure market’s development of everything from oils for vaping to edible candy.
The key to all products, however, is the extraction stage. Use of advanced chemical techniques and high-tech industrial machinery has allowed cannabis producers to experiment with new approaches. These state-of-the-artwork methods have led to new forms of cannabis extracts such as vape oils, oral tinctures, crumbles, and wax concentrates.
The three most used extraction techniques by the cannabis business are alcohol extraction, hydrocarbon extraction, and supercritical carbon dioxide (CO2) extraction. As with most things in life, there are pros and cons for each of these methods.
Alcohol extraction makes use of ethanol and could be performed cold, sizzling, or at room temperature. It stays some of the environment friendly extraction methods. However, the recent ethanol typically extracts unwanted chlorophyll and plant waxes and requires clarification or correction steps. The cold process reduces these contaminants at the price of longer extraction times. Room temperature ethanol extraction splits these differences.
Hydrocarbon extraction uses butane or propane, solvents with a lot decrease boiling points than ethanol. These solvents extract more of the plant terpenes, which provide more flavor and aroma and are therefore higher for vape oils or oral tinctures. Nevertheless, like the alcohol methodology, scaling as much as massive batches is tough and presents significant safety hazards.
CO2 extraction necessitates expensive, high tech specialized pressure and temperature management equipment to deal with turning gaseous CO2 right into a supercritical fluid or cryogen. The liquid CO2, with careful control, simply extracts oils and waxes and in some uses requires little to no post-processing. The CO2 extraction process is highly tunable, permitting completely different pressures and temperatures to extract distinctive botanical compounds.
Safety considerations
Following the discussion above, it is obvious that two of the three predominant extraction strategies involve use of extraordinarily flammable solvents. The third entails the use of a cryogen with its own particular safety concerns. Due to this fact, cannabis extraction, particularly at production scale, entails some significant safety issues.
First, identify all hazards. This begins by building a chemical inventory or list of chemicals with related essential information akin to materials owner, date acquired, quantity on hand, storage location, and accompanying safety data sheet (SDS).
SDSs are the second critical part and contain sixteen particular sections detailing information on the chemical’s constituents, physical properties, health hazards, first aid measures, personal protective equipment, and particular handling and disposal requirements.2 The SDS contains all of the information wanted to develop your HCP and is critical if an publicity or incident occurs. Ensure access to the SDS is available within a couple of minutes always (e.g. 24/7).
Train employees
After identifying hazards and building inventory of hazardous chemical compounds, conduct the communication part of the program. This means getting the critical information to workers (e.g. training our workers on the hazards of every chemical).
In addition to the hazards, workers ought to receive training on the potential publicity routes, signs, and signs of exposure and chemical warning properties (or lack thereof). Training should also embrace any personal protective equipment needed for using the chemical as well as incident response, mitigation steps, and first aid measures.
Preventive and proactive health and safety is essential—this means the timing of training matters. All staff ought to obtain training previous to beginning any work with hazardous chemicals. Annual refresher training is highly recommended. Conduct a thorough evaluation and re-training after any shut-call or incident.
Evaluate exposures
Industrial hygienists are trained to anticipate, recognize, consider, and management all potential health and safety hazards within the workplace. Knowing that many chemical solvents pose significant risk for exposure and health consequences, we should admit that exposure assessments are necessary.
