What is Dry Ice?
Dry ice is a solid form of carbon dioxide. When carbon dioxide is subjected to extremely low temperatures, it solidifies and is shaped into various forms that make dry ice used for multiple applications. It has an average temperature of -78 degrees Celsius (or -109 degrees Fahrenheit).
What is dry ice made of?
Dry ice is made of carbon dioxide. Carbon dioxide is subjected to high-pressure levels and extremely low temperatures to turn the gas into a solid form. This forces the gas to be condensed and become liquid before it undergoes further manufacturing operations to turn into solid blocks or pellets.
Is dry ice harmful?
Dry ice can be harmful when not properly handled. When using or working with it, make sure the space is well-ventilated. When dry ice 'melts,' it releases carbon dioxide into the air. If you are working in a small area without proper ventilation, it can cause the CO2 to build up. When inhaled, it can cause someone to become unconscious or lead to fatal consequences.
How do you make dry ice?
This product goes through a strict manufacturing process that involves multiple processes. Starting from the gas form of carbon dioxide, it goes through condensation to transform it into the liquid until it becomes solid in its final form.
Is it the same as liquid nitrogen?
No. Dry ice is the solid form of carbon dioxide. On the other hand, liquid nitrogen is a nitrogen gas that is cooled and pressurized until it becomes liquid.
How do you store dry ice?
Keeping this product in an insulated cooler or container with minimal open space is essential. This type of storage helps slow down the sublimation process, wherein dry ice sublimates into vapor which is carbon dioxide gas.
Never store dry ice in a freezer or refrigerator as the buildup of carbon dioxide released by the product can force it to open, if not cause damage. Dry Ice in large quantities in a freezer can damage the thermostat. In the event of an emergency if you need to store a product with dry ice in your fridge or freezer ensure that the dry ice is covered and distributed in small quantities around the area that needs to be kept cool. This way the cool air will be diffused and not concentrated in one area.

How does dry ice work?
Dry ice must maintain a temperature of -78 degrees C (or -109 degrees F). At this temperature, it is effective as a cooling agent. As time goes by, it slowly vaporizes into gas in a process known as sublimation. You can speed up the release of gas by placing it on water, forming thick, white fog.
How much dry ice do you need to store food?
It depends on the amount of food that you need to store. In general, you will need a few kg of dry ice for a standard-sized cooler.
In an emergency power outage, use dry ice to keep your freezer cool. You'll need about half to one kg of dry ice per cubic foot.

Will dry ice freeze water?
No. Dry ice will sublimate or release vapor when you put it in water. However, there will be a capsule of ice around the dry ice where the water is directly exposed to the dry ice. That can even seal and a small pin drop could appear where the sublimated gas can escape from. However, care must be taken not to ingest the ice as there could be a small piece of dry ice still embedded within it.
How do you dispose of dry ice safely?
The proper way to dispose of dry ice is to leave it in a cooler in a well-ventilated area. If the cooler is empty, you could even leave the cooler closed as the sublimation process continues although at a slower rate than if it were left open. The product will naturally undergo sublimation, turning into a gas and released into the air. Therefore, it will leave no residue behind once it fully evaporates. Never dispose of it onto the drain or a trash can as it can cause the pipes to freeze and damage the trash can via extreme freezing.
Is it okay if dry ice touches food?
You must prevent dry ice from touching your food products directly. When this happens, it freezes the food. Unless you need your food frozen, always keep a layer of cloth or towel in between to keep the food cool but not frozen.
Is dry ice flammable?
No, dry ice is non-flammable. It emits a colorless gas, but it won't catch fire.
Is putting dry ice in drinks safe?
Yes, you may put only food grade or 99.99% pure dry ice in drinks. But make sure to avoid swallowing or ingesting the blocks of dry ice. You can sip the drink if you do it with a straw and avoid placing the straw near the dry ice. Or sip the drink from the top while the dry ice is at the bottom of the glass.
What happens if you put dry ice in water?
Putting dry ice in water will trigger the sublimation process or release carbon dioxide gas. If you use hot water, it will speed up the effect and cause the release of fog.
Who invented dry ice?
French chemist Charles Thilorier invented dry ice. It was believed that he first published the account of the dry ice phenomena in 1835.
How long will dry ice last?
Several factors determine how long dry ice will last, such as packaging, the external temperature, the ambient pressure, and the insulation used in the packaging materials. On average, it will last 3-5 hours at room temperature or 18 to 24 hours when stored in a cooler.
Can dry ice melt?
No. Dry ice is not the same as regular ice that melts into a liquid when subjected to high temperatures. Instead, it transforms into gas, releasing carbon dioxide.
Is dry ice reusable?
No, it cannot be re used. Once it undergoes the sublimation process, it transforms into gas with no secondary contaminant left behind (for example ice leaves water as a secondary contaminant), so no visible residues are left behind.
Is dry ice toxic to breathe?
Dry ice is odorless, and the gas it releases is, too. However, it would be best if you were extra careful when inhaling the carbon dioxide as large amounts of it can be toxic and fatal as it can displace oxygen in the body. This is why it is recommended that you use this product in a well-ventilated area and never directly inhale the sublimated C02 as it is not oxygen and can cause a gag reflex.
Once it has blended into our atmosphere after sublimation from the dry ice in a normal room or open area it can be inhaled with the air from far without any adverse effects on us. C02 should never be inhaled in concentrated form. Once again, Carbon dioxide is produced in our bodies during metabolism and it is a normal component of our exhaled breath. CO2 levels in our sea level air ranges from about 300ppm - 400 ppm (0.03% to 0.04%) but it can fluctuate to as high as 600-900 ppm in densely populated cities and urban areas. Dry ice is used for blending with meat products and the CO2 levels immediately close to an open container of dry ice can be as high as 12,000 ppm and brief exposures to this have no adverse effects so purchasing small quantities of dry ice and inhaling close to the drinks or food items would be much lower than this. If dry ice is used in rooms without proper ventilation the CO2 can be measured to be as high as 30,000 ppm.

What happens if you accidentally touch dry ice?
Dry ice should never come into contact with our bare skin for more than one second. One should never actually hold it or play with it physically. If this accidentally happens, you will notice a redness in the affected area or be able to see some other signs of frostbite. Make sure to seek immediate medical attention.
Will dry ice cracks plastic?
Yes. The extreme cold can cause the plastic material to crack. Always use a protective layer such as a newspaper or a cloth, and never put dry ice directly onto any surface.
Does dry ice damage stainless steel?
It can cause the metal to change its shape as it will freeze it and shrink it depending upon the shape of the metal. You should always avoid placing dry ice directly onto any surface as it can cause damage to the said surface and create a funny buzzing sound, including stainless steel. Always place a protective layer in between the surface and dry ice unless there is water in the vessel then it is fine as the dry ice will not be in direct contact with it.
How do you use dry ice?
It is used primarily as a cooling agent as it is a passive refrigerant. Therefore, one of the most common applications of dry ice is to keep fresh food frozen and extend its shelf life. It is the go-to choose for storing and transporting perishable goods like fruit and vegetables, meats, ice cream etc., that must be held at a very low temperature.
It is also used commercially for airline catering, food distribution, meat processing, and restaurants. Other applications for this product are shipping pharmaceutical products and science lab experiments in schools and universities.

Is Dry Food preservation and extension of shelf life with dry ice possible?
This is where the term “unique” can be coined for special dry ice uses. It can also be used in the storing of dry food products such as rice, grains, and legumes for extended periods of time. Ensure your dry ice is at the bottom of your storage container, then fill your dry food items on the top. Keep the lid slightly ajar to avoid a pressure build up as the dry ice sublimates. After a few hours the dry ice would have fully sublimated, replacing all the oxygen in your container with the anaerobic carbon dioxide. After this you can steal your lid shut and your food will be safe from spoilage for a long time. Additionally, without the presence of oxygen, bugs and bacteria will not be able to survive. It is unique because there is no other product that can exist as a solid, liquid and a gas.
How much dry ice do you need to produce fog for special effects?
Dry ice is a sought-after product for its ability to produce fog or that smoking effect. Four gallons of warm water for every two kg of dry ice are ideal for making fog. Of course one could choose to venture further to add to the theatrics and double or triple this; however, care should be taken that this should be done in a ventilated area and this should never be attempted in a closed room unless it is a large hall more that 2000 sq feet for this quantity of fog.
What are the medical uses of dry ice in the pharma and medicine industry?
Dry ice is deemed as safe in its application for the refrigeration and cooling of medical and pharmaceutical and sample storage. Since its low temperature can be controlled via special equipment it is also widely used by doctors in the medical profession to freeze and remove warts or to address skin irregularities.
As Dry ice is much colder than ice with a temperature of about -79°C; ice is at -2°C. Additionally, Dry ice stays cold for longer periods and does not melt leaving a watery bacteria filled mess; it sublimates, turning into gas over a period of 48 hours (depending upon its storage) which is why it is an ideal passive refrigerant for shipments protecting cargo for several days as they reach their destinations.
There are several more vital applications for dry ice in the medical industry. It is used for preserving organic and biomedical samples such as blood and organs, tissues as well as other temperature-sensitive organic substances. This product can be used for storing and transporting other essential medical products like vaccines and other perishable goods.

How much dry ice do I need?
It depends on your intended application for dry ice. There are several factors that you must consider when determining the amount to use for your intended application, such as the length of use, weight, and the packaging. If you are using it to transport food for a picnic you would need a smaller quantity. If you are exporting food products on a flight that is longer than a few hours you would need several times the quantity as it sublimates and if you need to keep your food freshly cooled or frozen, you will have to account for the door-to-door logistic cycle time and temperatures involved. In such cases you can contact your reliable local dry ice supplier and they will give you the correct advice based on your requirements.
Additionally, a good example of this is that the amount of dry ice you need for keeping foods frozen versus keeping them fresh are different. If you cannot decide how much to use, it is best to consult a dry ice specialist in Dubai like Carbonic International as they can recommend the right amount based on your exact needs.
