Meaning and Definition
Solid carbon dioxide (CO₂) formed at very low temperatures, appearing as a white, frost-like substance.
Used as an industrial cryogen for freezing, in fire suppression systems, and in certain medical and dermatological procedures for cryotherapy.
Dialectal Variation
British vs American Usage
Differences
The term itself is identical. Regional differences lie in associated vocabulary (e.g., 'lorry' vs 'truck' for transport). 'Dry ice' is the far more common term in both varieties for the same substance in general contexts.
Connotations
None beyond its technical/scientific precision. 'Dry ice' has wider recognition and more everyday connotations.
Frequency
Extremely low in everyday speech in both regions. Confined to highly technical manuals, scientific literature, and specific industrial contexts.

Common Mistakes When Using “carbon dioxide snow”
- Using it interchangeably with 'ice'. It is not water ice. Pronouncing 'dioxide' as /daɪˈɒk.saɪd/ (UK) or /daɪˈɑːk.saɪd/ (US) is correct; /ˈdaɪ.ək.saɪd/ is incorrect. Confusing it with carbon monoxide.
FAQ
Frequently Asked Questions
Yes, they refer to the same substance: solid carbon dioxide. 'Dry ice' is the common, commercial name, while 'carbon dioxide snow' is a more descriptive technical term often referring to its freshly generated, loose form.
It is called 'snow' because when gaseous CO₂ rapidly expands and cools, it condenses directly into a solid, forming a fine, white, frost-like powder that resembles snow in appearance.
No, you should never touch it with bare skin. It has a temperature of approximately -78.5°C (-109.3°F) and will cause severe frostbite (cryogenic burn) almost instantly. Always use insulated gloves and proper handling tools.
Its primary uses are as an industrial refrigerant (e.g., shipping perishables), for special effects (fog), in cryogenic cleaning (e.g., blasting surfaces), and in certain medical treatments like cryotherapy for removing skin lesions.
Solid carbon dioxide (CO₂) formed at very low temperatures, appearing as a white, frost-like substance.
Carbon dioxide snow is usually technical/scientific in register.
Carbon dioxide snow: in British English it is pronounced /ˌkɑː.bən dʌɪˈɒk.saɪd snəʊ/, and in American English it is pronounced /ˈkɑːr.bən daɪˈɑːk.saɪd snoʊ/. Tap the audio buttons above to hear it.
