Rosemary extract from Rosmarinus officinalis leaves is used for many health benefits and as a natural food preservative. This extract is rich in bioactive compounds like carnosic acid, rosmarinic acid, and other antioxidants. These compounds contribute to its calming, antimicrobial, and anti-proliferative effects. With many benefits, rosemary extract is a valuable addition to health and beauty formulations.
Organic Rosemary Extract CO2 is a thick, dark brown botanical extract from dried leaves of Rosmarinus officinalis using supercritical carbon dioxide extraction. This method preserves the plant’s natural antioxidants – mainly carnosic acid and carnosol – which are very effective in extending the shelf life of vegetable oils, butters, and oil-based formulations. The presence of these compounds enhances their antimicrobial activity and is effective against microbial growth and biofilm formation.
In cosmetic manufacturing, oxidation is one of the main cause of reduced product performance and shelf life. By adding Organic Rosemary CO2 Extract to your formulations,
you can slow down the oxidation process and maintain product integrity, scent, texture, and colour without synthetic preservatives. The extract can also darken lighter coloured oils, which may be a consideration in your formulations.
Unlike rosemary essential oil, which is known for its aromatic benefits, this CO2 extract is a powerful antioxidant and ideal for functional skincare and haircare formulations. A little goes a long way – it’s cost-effective and efficient. The different extracts of rosemary have different activity patterns, including antioxidant properties, which contribute to their therapeutic effects.
Whether you’re making a natural face oil, organic balm, whipped body butter, or hair serum, this ingredient helps you deliver high-performance results while meeting clean beauty standards. Its properties also add extra utility when formulating with sensitive botanical oils that are prone to spoilage.
Even though this botanical extract comes from the Rosemary plant, it is not the same as Rosemary essential oil and the essential oil does not have the antioxidative properties of the extract. The two products are in no way interchangeable.

What’s the difference between rosemary extract and rosemary essential oil?
Rosemary CO2 extract is a highly concentrated antioxidant ingredient with aroma, ideal for product preservation. Rosemary essential oil is aromatic and used in aromatherapy, but lacks antioxidant strength. The effectiveness of rosemary extract in various applications, such as food preservation and skincare, is well-documented.
Can I use this in water-based products?
No, Organic Rosemary Extract CO2 is oil-soluble and must be used in oil-based or emulsified formulations.
Does it affect the smell or colour of my products?
Yes, it has a strong herbal smell and can darken lighter coloured oils. Use in small amounts or with stronger scented essential oils to mask the aroma.
How much do I use?
0.02% to 0.1% in most formulations. Much cheaper than synthetic options.
Vegan and cruelty-free?
Yes, our Organic Rosemary Extract CO2 is vegan and cruelty-free.
Is it a preservative?
While it slows down oxidation in oil-based products, it does not prevent microbial contamination in water-based formulas. It’s an antioxidant, not a full-spectrum preservative.
Can I use it with Vitamin E (Tocopherol)?
Yes, using it with Vitamin E offers extra protection against rancidity, especially in sensitive oils.

"High quality"
"Beautiful Product, Fast Shipping and Packaged Perfectly. 100% Recommend."
"Is good oil"
"Absolutely love this CO2 organic rosemary extract. The fragrance is not as strong as essential oil and yet it is more potent. I use it in my hair oil and its not as overwhelming. I recently used it on insect bites while in garden which was v itchy and inflamed. This oil + a drop of T tree oil worked like magic. Itching/inflammation both stopped and got better within 2 days. Will buy again. Thank you"
