Product Description
Rosemary Extract Introduction
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.
Product Description
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.
It does have a strong smell and may also darken the colour of lighter oil blends.
How to use it
How to Use
Skin Care
Oils that are very high in polyunsaturated fatty acids are immensely beneficial to the skin, but they have a very short shelf life, often less than six months.
A very small amount of Organic Rosemary Antioxidant will substantially slow down the oxidation of these oils, meaning they can benefit the skin for longer.
Hair Care
No direct hair usage, but if your hair product contains a polyunsaturated fatty acid oil, then it could be included.
Other
Use 0.05% to 0.1% when working solely with saturated fats like Cocoa Butter and Macadamia Oil.
Use at 0.2% to 0.4% with predominantly Polyunsaturated fatty acids like Kiwi Seed Oil and Rosehip Seed Oil.
It is more stable than Vitamin E as an antioxidant, although it is more commonly used for the shelf life of the product.
When using blends of oils, consider which ones are the most vulnerable to oxidation and what their ratio is in the blend.
Oil soluble, so it cannot be used in water-only products.
When making oil-only blends, Rosemary Antioxidant can make the finished blend darker.
We have found that using a low percentage of EcoSilk in the blend helps to keep the blend a little lighter in colour.
It does depend on the blend, so experiment with small amounts first.

FAQ's
FAQs
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.

Carnosic Acid
Carnosic acid, the main active in Organic Rosemary CO2 Extract, is an antioxidant. This phenolic diterpene naturally stabilises oils by neutralising free radicals that cause oxidation and spoilage.
Sustainable Extraction Method
Supercritical CO2 extraction is a clean and eco friendly process that uses carbon dioxide under high pressure to extract plant actives without leaving any residues. This method preserves volatile and non-volatile components and retains high purity and potency.
