Rosemary Oleoresin Extract (ROE) - Hexane Free

Rosemary Oleoresin, also known as Rosemary Oil Extract or ROE is an oil soluble, natural extract used to retard rancidity in natural oils. Its potent antioxidant properties are attributed in large part to carnosic acid, one of its major constituents. Rosemary Oleoresin is available with varying levels of carnosic acid. Ours is highly concentrated and standardized to 7% carnosic acid for the highest level of activity, making its use at very low percentages both effective and economical. Typically, 0.2 - 0.5 grams will be added to 1000 grams of oil.

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 this added to the balance of the oil with thorough mixing.

Rosemary Oleoresin (ROE) has a very mild herbaceous odor which is generally unnoticeable in final formulations when used at recommended usage levels. It is a high quality product lacking the pulp or graininess often found in lesser Rosemary Oleoresin products. In addition to Carnosic Acid, Rosemary Oleoresin also contains Rosmarinic Acid, Rosmaridiphenol, Carnosol, Rosmanol, and Rosmaridiquinone.

Appearance: Light brown viscous liquid
Carnosic Acid Content: 7% minimum
Solvent used for Extraction: Acetone
Flashpoint: >212°F (100°C)

Our Customers Say...
Love the new website!
Jen is such a pro when it comes to prompt & courteous customer service, plus shipping rates are as reasonable as possible these days - not like some sites that just gouge you.
I'm a small customer, but always feel that my business is valued.
Thx, Jen.

The shealoe butter is to die for. It is great on skin and very dry hair. I mixed a tablespoon of glycerin and honey quat in the shealoe butter. Pure perfection!! The moisture and sheen it gives is excellent. Also, the service is great. Received my items prompt and secure.
