‘Chilly-pressed’ has turn into a buzzword over the past decade for every part from juices to olive oil.
It’s additionally some of the widespread methods to extract natural oils for skincare. You’ll usually hear manufacturers singing its praises – however it’s not essentially the perfect extraction technique.
So what does cold-pressed imply?
Chilly-pressed oil is obtained by urgent and grinding fruit or seeds with using stainless-steel presses.
The uncooked plant materials is positioned between horizontal plates that are drawn collectively by a rotating screw (the ‘expeller’), and the oil is squeezed out.
Regardless of the title, a specific amount of warmth is produced through the course of attributable to friction, averaging at about 40˚C. To be marketed as cold-pressed, the temperature should keep beneath a fairly toasty 49˚C.
Identical to if we have been subjected to those temperatures, delicate components can find yourself lower than ‘recent’ and plenty of of their therapeutic properties are misplaced.
There’s additionally oxygen current throughout cold-pressing. This causes oils to oxidise instantly, making them extra more likely to turn into rancid earlier than you’ve had an opportunity to make use of them up!
What’s the choice?
At Pai, we use Tremendous Essential CO2 Extraction wherever extra delicate components are concerned.
This extraction technique makes use of volcanically-sourced CO2 in its tremendous crucial (fluid) state. It’s handed by the uncooked plant materials, extracting all biologically ‘energetic’ parts because it goes.
This course of takes place at 30°C with none thermal stress and with out utilizing natural solvents. As a result of CO2 is chemically inert the extraction is finished in a digital vacuum, with no oxygen current.
CO2 extraction vs cold-pressed
CO2 extraction is greatest as a result of oxygen-free environments and low temperatures are significantly vital when extracting fragile oils like Rosehip.
By retaining temperatures low and extracting all of the ‘energetic’ parts, we’re in a position to protect and defend the entire botanical, skin-loving properties of the Rosehip.
This course of delivers twice the regenerative sterols and 5 occasions extra of these carotenoids than your common Rosehip seed oil. It additionally means it lasts 4 occasions longer in your rest room cupboard!
This contains the unimaginable pure color and odor. You solely must see how orange, concentrated and herbaceously-scented Rosehip BioRegenerate is to witness CO2 extracts at their greatest!
CO2 extraction additionally leaves completely no solvent residues, so the ultimate oil is impeccably pure. The low temperature and lack of waste streams/emissions make it a particularly environmentally pleasant course of, too!
