CPF Supercritical Fluid CO2 Extracted Coffee Oil

What is
CPF Supercritical Fluid CO2 Extracted Coffee Oil?

CPF Supercritical Fluid CO2 Extracted (SC-CO2) Coffee Oil is an oil extracted from Spent Coffee Grounds (SCGs) using a unique extraction technique called Supercritical Fluid Extraction. What makes this extraction method unique is the extraction process has the advantages of a solvent extraction without the use of toxic and dangerous solvents. This is achieved by using Carbon Dioxide gas (CO2) pressurised to over 1,000 psi and heated to over 31 degrees Celsius. which turns the CO2 gas into a supercritical fluid, turning the CO2 into a solvent. The CO2 gas is recycled in the extraction system and any CO2 gas left in the extracted oil evaporates, leaving behind no trace. What is left behind is a pure coffee oil that is high in omega fatty acids and other helpful compounds. CPF SC-CO2 Coffee Oil is suitable for use in cosmetics and functional food.

Key Compounds of
Supercritical Fluid CO2 Extracted Coffee Oil

Palmitic Acid – Acts as an emollient/surfactant, softening the skin and helping retain moisture by forming an occulusive layer. Furthermore, it may help to prevent free radical damage, maintaining youthful radiant skin.

Stearic Acid – a saturated long-chain fatty acid and is used in a variety of cosmetics and personal care products, as a fragrance ingredient, surfactant, and emulsifier. 

Linoleic Acid (Omega-6) – a fat that helps promote healthy cell activity. Like Oleic Acid, Linoleic Acid is an anti-inflammatory and help stimulate cell regeneration. Together, Oleic and Linoleic Acid deliver and secure moisture within the layers of skin most affected by damage and dehydration, as well as soothing, healing, and protecting skin from harsh elements that expedite aging. 

Alpha-Linolenic Acid (Omega-3) – an unsaturated fatty acid, and a member of the essential fatty acids called Omega-3 fatty acids. Omega-3 fatty acids can modulate the expression of several genes, including those involved with fatty acid metabolism and inflammation. 

Oleic Acid (Omega-9 Fatty Acids) – Easily and deeply penetratesthe skins surface, replenishing lost moisture that naturally comes with age, and stopping remaining moisture from evaporation. It helps fight free radical damage caused by environmental agressors like UV rays by minimizing free radical exposure to the skin, this feature also stops the formation of wrinkles, fine lines, dark spots, sagging and other unwanted features. Used as anti-inflammatory substance, oleic acid stimulates wound healing. Oleic acid can also help repair skin in immensely damaging conditions such as eczema, rosacea, and psoriasis. It also contains compounds that reinforce the integrity of cell membranes. 


Australian’s love coffee: on average, Australians consume 1.91 kilograms of coffee per person in 2021, 0.7 kilograms of that being roasted coffee beans. That’s 17.9 million kilograms of freshly ground coffee! This also generates 17.9 million kilograms of food waste. After a cup coffee is brewed using roasted coffee beans, the Spent Coffee Grounds typically finds its way into landfill.


Spent Coffee Grounds release methane into the atmosphere while decomposing, a greenhouse gas that has 20 times the global warming capacity of carbon dioxide.


Besides the environmental effect of brewing a cup of coffee, the Spent Coffee Grounds still have significant nutritional value; only a fraction of the nutritional value is extracted when brewing coffee.


By upcycling and repurposing the Spent Coffee Grounds into useable products, we can help divert methane producing waste from going into landfill and redirect nutrition back into the functional food supply chain.

How is CPF Coffee Oil made?

First, the Spent Coffee Grounds made from roasted coffee beans that are collected from local coffee shops in food safe containers specifically for Spent Coffee Grounds, ensuring the Spent Coffee Grounds are free of contaminates. The collected Spent Coffee Grounds are then brought back to CPF Green Solutions facility in Brisbane.


The fresh Spent Coffee Grounds are then gently dried using a natural gas fired hot air drier at an optimal temperature for quick drying but keeping the nutritional value intact and then sifted to remove any contaminants.


The next step extracts the oil from the SCGs using a green and sustainable technology known as Supercritical CO2 Fluid Extraction (SC-CO2). SC-CO2 is substitute to traditional solvent extraction methods that uses non-toxic and environmentally friendly CO2 at high pressures to extract material from biomass. SC-CO2 also has anti-microbial properties, ensuring a safe, clean, and sterilised product. [1]


The remaining de-fatted coffee grinds are removed for further processing to be turned into Nukaffe Coffee Flour and the Coffee Oil is then filtered to remove waxes and solids extracted during the extraction process, leaving behind a pure oil.
