Rosehip Oil Extraction Process

Kosmea’s Rosehip Oil is 100% certified organic grown wild without pesticides and fertilizers. It is extracted using a heat-free and solvent-free process called super critical extraction.

Due to the sheer hardness of the rosehip seed the friction in cold pressing generates heat above 30°C, this can destroy some of the valuable components of the oil. Super critical extraction does not generate heat as it is processed at temperatures below 17 °C.

Rosehip oil is a fruit oil rich in essential fatty acids, powerful antioxidants, lycopene, beta-carotene and vitamin C. These vitamins feed the structure of the skin, repairing damaged skin tissue and creating new skin cells. Rosehip oil is a unique skin care ingredient and at Kosmea we make a very unique rose hip oil.

  • We source our rose hips from a certified organic source from a region where the rainfall is high and therefore the rose hips are plumper, richer and juicier
  • We use both the fruit skin and seed of the rose hip, giving our rose hip oil a high content of the antioxidant, lycopene
  • We use the super critical extraction process which is heat-free and solvent-free so our rose hip oil stays just as nature intended
  • We do not bleach, colour or deodorise our rose hip oil to make it more commercially attractive as this would deplete the natural goodness of the oil

In order to preserve the maximum amount of vitamins, essential fatty acids and antioxidants in the rose hip oil, it is extracted using a heat-free and solvent-free process called super critical extraction.  Heat, air, water and light can all affect the quality of the oil and so we avoid these as much as possible during the manufacturing process. 

Super critical extraction involves passing a natural gas (CO2) through the rose hips to gently extract the oil.  This process is expensive and timely, but ensures that the maximum amount of goodness is captured. Kosmea does not cold press or use solvent extraction to extract its rose hip oil as both of these processes deplete the goodness of the oil by overheating (cold press) and using potentially harmful solvents (solvent extraction).

Kosmea’s super critical extraction process of rose hip oil is a process which starts by collecting the organically grown rose hips and then placing the hips into a pressure vessel. This pressure vessel is sealed and then has liquid carbon dioxide (CO2) gently run through it. Pressure is applied and the liquid CO2 is able to remove the rose hip oil from the hips. This liquid is then collected and as the pressure and temperature are changed the CO2 reverts back to a gas leaving the pure rose hip oil behind. This super critical extraction process has the advantage of leaving zero amounts of any solvent (CO2) behind with the rose hip oil and does not involve high temperatures which may also adversely affect the natural aroma and colour of the rose hip oil. It is an organically certified process which produces the highest quality oil.
