What is Rosemary Antioxidant CO2 used for?
Rosemary Antioxidant CO2 is a concentrated rosemary extract widely used in cosmetic formulation to help slow the oxidation of oils - extending the usable life of balms, body oils, massage oils, and other anhydrous skincare. It isn't a preservative in the biocide sense (it won't prevent microbial growth), but it is one of the most popular natural antioxidants small-batch skincare makers reach for.
Is rosemary CO2 extract the same as rosemary essential oil?
No, they are two different products made by two different processes. Rosemary Essential Oil is steam-distilled from the leaves and is prized for its aroma. Rosemary Antioxidant CO2 is extracted using pressurised carbon dioxide, which captures a different fraction of the plant - high in rosmarinic acid and carnosic acid. Essential oil is for aroma and aromatherapy; CO2 extract is for formulation and antioxidant activity.
How much Rosemary CO2 should I add to my skincare formulations?
A typical use rate in anhydrous products (oils, balms, salves) is 0.05%-0.5% of the total formula. You may want to start at the lower end, the extract is potent and carries its own colour and scent that can come through into the finished product. For example, a 0.1% addition to a 100ml body oil is 0.1ml (about 2-3 drops).
Does Rosemary Antioxidant CO2 extend the shelf life of natural oils?
Yes, added at typical rates, it helps delay rancidity in carrier oils and oil-based products by slowing lipid oxidation. It's a popular choice for small-batch skincare makers looking for a natural alternative to synthetic antioxidants. For water-containing products (lotions, creams), you will still need a proper broad-spectrum preservative rosemary CO2 is an antioxidant, not a preservative.
