The nitrous oxide sold in cream chargers is 100% pure for human consumption. It is sold as a whipped cream propellant for use with whipped cream dispensers.
The primary reason for the selection of this gas for use in whipping cream is related to its chemical interaction with the fat molecules within the cream - there are some interesting experiments that you can try at home to demonstrate these properties.
There are other uses for it due to the chemical properties of the Nitrous Oxide gas most notably as an oxidizing agent in mini rocket motors. We advise caution in any off-label uses of the product and cannot condone it but have included some interesting reference materials for your information.
Here at Cheeky Monkey Cream Chargers we also like our customers to take an interest in the products we buy so you might also be interested to read a little about the history and discovery on the gas - Joseph Priestley in the year 1772. The amazing man Priestly as well as synthesizing N2O also discovered Oxygen and Sulphur Dioxide - which means without him then the earth's atmosphere would have an entirely different composition.
As well as its numerous practical applications we feel it is important to note that N2O is a powerful greenhouse gas and a significant contributor to global warming. The majority of the gas present in the atmosphere is in fact either naturally occurring or from an industrial/agricultural source but the small 8gm chargers will also play their part so please use them responsibly.
Please be aware of the dangers involved when dealing with pressurized gases always read the hazardous materials information that is printed on the side of the packaging box your cream chargers will arrive in.
Do not be tempted to experiment with inhaling the gas - it has both long term and short term negative effects upon your health.
