About The Plant
An important culinary perennial herb, Rosemary grows in shrubs up to six feet high with leathery, needle-like silver-green leaves and small blue flowers. A native species to the Mediterranean, it has now spread throughout Europe, North Africa, various Middle Eastern countries and the states of California and Nevada in the USA.
Rosemary extract is among the most potent antioxidants known for preserving oils and fats. Rosemary has a unique ability to neutralize almost every class of free–radical. Additionally, while most antioxidants need to be restored or replenished once they've absorbed an oxidative radical, rosemary changes form and is able to neutralize a different class of free–radical molecules.
Recent research has noted that when ingested, relatively small amounts of Rosemary extract can stop oxidation in all "oil" or "fat" components of our bodies. This organic extract can be added to your carrier oil "stock", or to blends including carrier oils. This extract is known to be more effective than Vitamin E for natural preservation of your oils.
The suggested dilution ratio for effectively extending the shelf life of your carrier oils and blends is only 0.2% (1/5th of one percent), which is 1 to 2 drops of the extract per fluid ounce of carrier oil.
This extract has a mild rosemary aroma, though at effective concentrations should go unnoticed in terms of aroma in your formulations. The extract is fairly viscous; the best way to work with it is to remove the orifice reducer from the bottle (only in the 10mL size–larger sizes do not include an orifice reducer) and use a glass eye dropper to measure drops into your formula (eye droppers are supplied with 30mL and 60mL sizes and available for free by requesting one in the "comments" section of the checkout page). Cap your carrier oil or blend, and gently invert and swirl so that the Rosemary extract is thoroughly distributed throughout your oil or blend.
While carrier oils (also known as "fixed" oils) are most susceptible to oxidation, essential oils high in linalool are also susceptible, as are citrus oils and needle oils from the Pinaceae family. Adding 1 drop per ounce of Rosemary Antioxidant to your essential oils of these varieties is not a bad idea if you intend to keep them for more than a year.
Add 1 to 2 drops of Rosemary Antioxidant to each fluid ounce of your carrier oils, blends containing carrier oils, or essential oils susceptible to oxidation.
