CO2 Extraction vs Cold Pressed
Naturally, there is a growing demand to use supercritical CO2 extraction in the cosmetic industry. It ensures the freshness of flavor, color, and odor – as well as quality(By keeping temperatures low and extracting all the ‘active’ components, such as extraction of the Rosehip: the co2 extraction process is able to preserve and protect the complete botanical, skin-loving properties, and delivers 60% more regenerative sterols and 20% more fatty acids than your average Rosehip Seed Oil.), especially when used to create oils that are highly susceptible to oxidation and rancidity.
While other extraction methods are competitively comparable, they cannot all be rated equally. And how oils are manufactured is essential to how the product will hold up – both on the shelf and on the market.

Contrary to its name, the cold-pressed extraction method may also involve using heat as a certain amount of heat is produced during the cold press process due to friction, averaging at about 40˚C. . Such a process can adversely affect heat-sensitive oils and further reduce its shelf-life, delicate ingredients can end up less than ‘fresh’ and many of their therapeutic properties are lost.
There’s also oxygen present during cold-pressing, when dealing with oxygen-sensitive oils, cold-press may not be the best extraction method. This causes oils to oxidize immediately, making them more likely to become rancid before had a chance to use them up.
Who is Better?
In contrast to cold pressing, with CO2 extraction no oxygen comes into contact with the plant material to be processed. In this way, the sensitive natural substances remain protected from oxidation, are more durable, and cannot become rancid so quickly.
CO2 extraction oil therefore the ideal raw material for natural active ingredient cosmetics. Compared to classic pressing, they are more productive, gentler, and antibacterial.
In general, CO2 extraction not only protects the raw material but also the environment, since this process does not cause any harmful emissions or water pollution. The carbon dioxide used can be used again and again in an environmentally friendly manner.
