Oil Oxidation and Oil Residue — Residue Killer of Vape Oil Quality

What Is Oil Oxidation and Rancidification?

Edible oil is one of the most affected food elements in oil oxidation and rancidification. Oil oxidation is an unpleasant sequence of chemical reactions in oil, lowering its quality and value. It entails the complete or incomplete oxidation or hydrolysis of fats. It can occur in several ingredients or contain products during the storage process that can be seen in the cannabis vaping industry, where the vape oil is stored in the oil tank for conservation between vaping intervals. This process constitutes rancidification, which can be understood as a function of many negative oxidative processes, including oil and lipid oxidations, according to the Food Science Technology journal written by Amaral. It adversely impacts the cannabis vape oil’s taste and odour, ultimately compromising the potency too. This is due to the rancidification process that originates from oxidation is responsible for its off-flavors and an unpleasant taste that characterizes poor quality cannabis oil often rejected by cannabis users. Given the desperation of quality and flavor retention toward cannabis vape oil due to its costly value, the issues of oil oxidation and rancidity have attracted attention significantly among cannabis users and vaporizer suppliers within the cannabis industry.

 

Why Edible Oil Like Cannabis Oil Oxidizes Faster Than Other Food Element?

Cannabis oil is like any other edible oil, contains antioxidant compounds, and fatty acids undergo speedier natural oxidation than those without these elements. Many research findings from food science and nutrition experts indicate that fatty acids catalyze the oil oxidation process, affecting oils’ physical attributes, such as color, viscosity, and degradation rate. However, this phenomenon may not be limited to the physical and chemical characteristics of the oil. Based on the research article Effect of Storage Temperature on Rancidity and Color of Palm Oil by Aboaba has shown that external interactions during storage and processing can also enhance rancidification. For instance, the application of high-pressure processing could limit rancidity due to full insulation from the air. Palm oils stored at ambient temperature retain their quality than those kept in extreme conditions. Their study results also indicate that the oils’ quality deteriorates when exposed to sunlight. The products are more susceptible to oxidative and hydrolytic rancidity when frozen and sunlight, respectively. It is imperative to point out that these theoretical concepts can be similarly applied and explained toward the oxidation speed of cannabis oil, where light exposure, oil processing, and oxygen concentration are notable external factors influencing its oxidative rancidity.

1. AIR EXPOSURE

Whether this stage is carried out by professionals or cannabis vaporizer users, the risk of damaging the cannabis oil usually peaks during the cannabis vaporizer oil filling process. The lengthy oil-injection period will allow the air to come in contact and oxidize the chemical composition of the cannabis oil, ultimately altering its color and taste.

 

SOLUTION: 

Cannabis vape enthusiasts and suppliers need to follow the rule of thumb to “Stop exposing the cannabis oil to the open air.” Cilicon launches the FLARE X1 Pro which adopted Oil Isolation™ Technology. The technology places the oil inlet under the oil tank to eliminate the possibility of oil leakage within an integrated device. Compared with traditional resting time that before capping after oil filling (3 minutes), it makes the resting time last longer so that enhanced production efficiency. On the other hand, less resting time is benefit for maintaining the steady air pressure in the oil tank that efficiently reduces air as less as possible in the oil tank in order to lower cannabis oil oxidation rate.

 

Also, based on Oil Isolation™ Technology, manufacturers can further push the central tube after the oil-filling and sealing-off process so that the oil inlet firstly enters the chamber. However,

At this time, it must take longer time to make oil successfully flow into oil inlet and to be absorbed into ceramic microporous because cannabis oil has already become viscosity but not a after heating fluid state. Therefore, If the oil inlet is pushed into the chamber after a longer period of resting oil, Cilicon advises you that you have better not choose too sticky cannabis extract. It suggests to assemble the whole device and enjoy your precious oil as soon as possible after processing it.

2. OIL TANK TRANSPARENCY

Light is not only a type of heat energy. It can be converted from light to chemical energy when it undergoes photosynthetic reaction, which is a type of oxidation reaction. Most of the oil tank for vape vaporizer is made of transparent material like PCTG or glass, making it convenient for consumers to observe the change of cannabis extract. Thus, the vape oil conserve inside the oil tank is inevitably exposed to sunlight during the consumption process oxidizes the vape oil in the cannabis vape device, deteriorating vape oil flavor and quality.

 

SOLUTION:

Most vape devices are prone to sunlight exposure oxidizing the vape oil in the cannabis vape device, compromising its original taste and smell. Cilicon tries to mitigate the issue by providing a customizable darker color of oil tank options for Elevate S2 product to cannabis users based on their preferences to preserve their vape oil safely in dark environments within well-lit places that minimizes sunlight absorption.

3. REPETITIVE HEAT

When consumers repetitively hit, battery rods will repeatedly heat the cannabis oil during this process. The oil absorption rate of the ceramic core is no faster than the inhalation rate of cannabis users. The discrepancy and unparallel rate of absorption and inhalation may lead to the heating coil burning excessively and cause the ceramic core to dry out from cannabis oil and produce a burnt taste. The overburnt scenario will begin damaging the ceramic core and produces carbides, mixing it with the leftover cannabis oil in the oil tank. This will alter its original vape oil into cloudy and generate harmful substances that are not ideal for cannabis users to inhale.

 

SOLUTION:

Cilicon has invested a significant amount of capital in ceramic factories and research institutes and collaborated with accredited university laboratories to develop advanced ceramic heating cores. Their infinite experiments have successfully produced perfectly identical microporous ceramic cores that maximize oil holding capacity. This increase in the ceramic core’s oil absorption indirectly matches up vapers’ inhalation rate, which helps mitigate the ceramic core and heating coil’s overburnt. However, when you encounter a burnt taste while vaping, you should still take a quick break from it to prevent excessive burning toward the ceramic core and protect your vape device from further damage.

 

What Are Oil Residues and Why It Compromises Vape Oil Quality?

Oil residues in the cannabis world can be explained as the remaining fraction left of substances that remain after a process such as combustion or evaporation during the vaping process. The cannabis oil residue contaminates the cannabis oil within the vaporizer. Two leading results caused by the deposit are the degrading clarity and quality. A persistent oil deposit changes the cannabis oil color to become murky and cloudy. It decreases the aesthetic value of the device. Furthermore, it generates a foul smell and deteriorates the taste and quality of the cannabis oil. Hence, the oil residue could negatively impact the cannabis vaping experience.

 

1. UNEVEN HEATING

The cannabis oil is usually viscous and thick. Therefore, only the bottom part closest to the heating surface is usually heated when the atomizer is heated. The heated purified product at the bottom will be liquified and acquire better fluidity, facilitating the flowing process into the oil hole while the remaining one is heated. The top first layer above the heating surface has no or minimum way to be heated since it is further from the heating surface. The uneven heating causes the flow rate to become very slow, forming the oil residue that remains on the surrounding surface wall of the atomizer oil tank.

 

SOLUTION:

There are cannabis atomizer manufacturers have launched a battery rod that can wrap the entire oil tank of 510 for heating instead of the traditional bottom heating plate in the cannabis market. This battery rod can reduce the residual phenomenon that sticks on the surrounded surface. However, the terpenes can be damaged due to repeated heating. In addition, the quality of the cannabis oil cannot be guaranteed due to the heat dissipation of the vape device and repeated high-temperature heating. Cilicon is still studying how to solve this problem.

 

Another alternative solution is that consumers can heat the oil chamber with a hairdryer when the vape oil is almost at the edge of it. However, they need to pay attention to safety during the operation. Moreover, when repeating the original atomizer use, it is best to heat the atomizer with a hairdryer and avoid heating it directly with a lighter because it may be sweltering. The heating temperature is not well controlled. Further, some of the poor-quality atomizer oil cups or mouthpieces are deformed precipitation of harmful substances. Two links attached below are quick tutorials to help you resolve your issue.

 

2. WATER CONDENSATION

During vaping, it is normal for cannabis vapers to draw in breath from the vape air channels through the atomizing central tube to the mouthpiece during the suction, creating an inhale and exhale airflow from the vape device. During inhalation, the temperature of the smoke generated by the atomization is high. Still, the air channels through the atomizing central tube to the mouthpiece during the suction are colder naturally, resulting in the forming of the condensed water droplets. Sometimes, the poor design in the atomizing channel of the air path creates poor airflow circulation of a vape device. It elongates the trail of the smoke channeling from the oil inlet to the mouthpiece via a central atomizing tube, turning the vapor into tiny water droplets resulting in massive condensation around the surface wall. This becomes the culprit of oil beads formation that produces mucky oil residue.

Another scenario is where several conventional cannabis vaporizers have high voltages battery rod, generating excessive power resulting in high atomizing temperature produces enormous smoke. When too much of smoke is produced and vaper’s inhaling rate is no faster than the vaporing rate, part of the vapor will flow back to the vape device. This reversed stream of hot smoke lands on the colder temperature of the vape oil tank, creating an asymmetrical high and low air pressure contrast leading to natural phenomena like water condensation resulting in oil beads sticking around the surface of the oil tank. These oil beads eventually turn into oil residue as it lingers with the remaining balance of cannabis oil in the oil tank.

 

SOLUTION:

Do not forget to avoid storing your cannabis oil under cold temperatures below 16 °C, as excessive coldness will alternate the consistency of the vape oil. It is impossible to 100% eliminate water condensation from vaping process. Still, there are ways to minimize the incident or ways to filter the oil residue, conserving a safe and healthy vaping experience. Cannabis users are advised to find vape devices with excellent airflow design to shorten the vapor channeling time from the oil inlet to the mouthpiece, reducing the waiting period to minimize water condensation. Aside from the design perspective, flexible settings feature can be considered a must to enable different power adjustments to control the cannabis atomizer’s temperature that matches your vaping speed to minimize oil beads that lead to oil residue that originates from water condensation. Cilicon vape device that has BioBaleen™ Technology perfectly fits the above requirements. Not only does it serve as the filter cleaner for cannabis vaporizers to minimize vapers inhaling harmful substances from the remaining oil residue, but it also resolves the spit-back issue, killing two birds in one stone!

 

Why Don’t Consumers Like It? Because Of The Taste Changes or More of Other Reasons?

Oxidative rancidity and oil residues adversely impact the quality of the cannabis oil, resulting in oils’ off-flavor and foul smell, affecting its taste and smell, leading to an unpleasant vaping journey. Many cannabis users find this upsetting as it gives them money down to drain experience after paying an exorbitant price for the cannabis oil. They expect to be in seventh heaven while vaping regardless of whether it is for socializing or treatment purposes. On top of the vaping experience, oil oxidation and residue are not confined to taste alterations, but these chemical reactions and compounds are known as toxic and can compromise the nutritional quality of vape oils and predispose end-users to health and well-being threatening conditions. Hence, oil taste, poor vaping experience, potency, and the horrendous aesthetic value of the device due to murky oil are all critical but secondary reasons behind the dislike of oil oxidation and residues. The primary reason is its harmful substances, leading to an unsafe vaping experience. Therefore, cannabis users should carefully select the best cannabis vaporizer with advanced technologies to mitigate these issues and keep their cannabis oil or extract safely according to the above suggestions to minimize oil residue and delay oil oxidation.
