Rosemary Oleoresin Essential Oil
Rosemary Oleoresin, also known as Rosemary Oil Extract or ROE is an oil soluble, natural extract of the leaves of the Rosemary plant used to slow rancidity in natural oils. This anti-oxidant ingredient can be added to carrier oils, lotions, butters and more to help keep them fresh longer. Its potent antioxidant properties are attributed in large part to carnosic acid, one of its major constituents. It can be use in very low percentages and still be very effective. Typically, 0.2 - 0.5 grams will be added to 1000 grams of oil.
Rosemary Oleoresin (ROE) has a very mild herbaceous odour which is generally unnoticeable in final formulations when used at recommended levels.

As with any antioxidant, to be effective Rosemary Oleoresin must be added to oils when they are fresh, before oxidation has started. Additionally, it must be thoroughly dispersed in the oil. As Rosemary Oleoresin is a thick liquid, adequate dispersion can be difficult. We recommend it be predispersed in a small portion of the oil first and then added to the balance of the oil with thorough mixing.
