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 will not be far behind. Medical use is mainly centered 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 methods 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 reminiscent of vape oils, oral tinctures, crumbles, and wax concentrates.
The three most used extraction strategies 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 those methods.
Alcohol extraction makes use of ethanol and could be performed cold, scorching, or at room temperature. It remains one of the vital efficient extraction methods. Nonetheless, the recent ethanol usually extracts unwanted chlorophyll and plant waxes and requires clarification or correction steps. The cold process reduces these contaminants on the price of longer extraction times. Room temperature ethanol extraction splits these differences.
Hydrocarbon extraction makes use of butane or propane, solvents with much decrease boiling factors than ethanol. These solvents extract more of the plant terpenes, which provide more flavor and aroma and are due to this fact better for vape oils or oral tinctures. Nevertheless, like the alcohol technique, scaling up to giant batches is troublesome 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 makes use of requires little to no submit-processing. The CO2 extraction process is highly tunable, permitting completely different pressures and temperatures to extract unique botanical compounds.
Safety considerations
Following the dialogue above, it is apparent that two of the three primary extraction strategies contain use of extraordinarily flammable solvents. The third includes the usage of a cryogen with its own specific safety concerns. Therefore, cannabis extraction, particularly at production scale, entails some significant safety issues.
First, determine all hazards. This begins by building a chemical stock or list of chemicals with related essential information corresponding to material owner, date acquired, amount on hand, storage location, and accompanying safety data sheet (SDS).
SDSs are the second critical component and contain sixteen particular sections detailing information on the chemical’s constituents, physical properties, health hazards, first aid measures, personal protective equipment, and special handling and disposal requirements.2 The SDS incorporates all the information wanted to develop your HCP and is critical if an exposure or incident occurs. Guarantee access to the SDS is available within a couple of minutes at all times (e.g. 24/7).
Train staff
After figuring out hazards and building inventory of hazardous chemicals, 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, staff ought to receive training on the potential publicity routes, signs, and symptoms of exposure and chemical warning properties (or lack thereof). Training also needs to embrace any personal protective equipment vital for using the chemical as well as incident response, mitigation steps, and first aid measures.
Preventive and proactive health and safety is crucial—this means the timing of training matters. All staff should obtain training prior to starting any work with hazardous chemicals. Annual refresher training is highly recommended. Conduct a radical evaluation and re-training after any shut-call or incident.
Evaluate exposures
Industrial hygienists are trained to anticipate, recognize, consider, and control all potential health and safety hazards within the workplace. Knowing that many chemical solvents pose significant risk for publicity and health consequences, we must admit that publicity assessments are necessary.
