Process and container for supplying supercritical CO2

摘要

A bottle 1 fitted with a dip pipe 3 contains a mass of liquid CO2 containing 3 to 6 % of dissolved helium, having above it a gaseous head space consisting of helium at a pressure greater than approximately 135 bars. Supercritical CO2 containing a few % of dissolved helium can thus be obtained merely by opening the stopcock 5 of the bottle. Application to the cosmetics industry.
