The chemical names for the fluorinated refrigerants are long and cumbersome. A numbering system was developed by Chemours to identify the different products. The number was originally part of the registered trade name but was later donated to the industry by the Chemours Company to avoid confusion and the proliferation of different numbers for the same product.

R290 (CARE 40) Propane R290, also known as CARE ® 40, is refrigerant grade propane, a natural, or 'not in kind', refrigerant suitable for use in a range of refrigeration and air conditioning applications. The use of R290 is increasing due to its low environmental impact and excellent thermodynamic performance. It is non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential). It is a flammable refrigerant and therefore not suitable for retrofitting existing fluorocarbon refrigerant systems.
