    Sold by weight. Our Rosemary Oil Extract (ROE) is a food grade product*. ROE is a thick, dark green/brown liquid extracted from the bark of the rosemary plant.   It has a definite herbal aroma and is used for preventing rancidity in products in which vegetable/plant oils have been used. Its color will vary from batch to batch. This product is made up of oil soluble antioxidant compounds and is not soluble in water, has no additives and is made of 100% rosemary oleoresin. The consistency of this product will also vary from batch to batch, sometimes more liquid, sometimes thicker. ROE is an anti-oxidant, it’s not a preservative.

    How To Use in Soapmaking: A good usage rate is about .05% of total fat weight in ROE.   This will be a tiny amount – about 4 to 8 drops per pound of finished soap.   This is about half to one gram of pure ROE per Kg of oil in your recipe or product, or approximately 1 tsp. to 1 tbsp. for each 10 Kg. or 22 lb. container.  If you dilute ROE in vegetable oil it makes it much easier to handle and to disperse. Should the oil/ROE mixture solidify, place the bottle in a pan of warm water to liquify it.

    Diluting ROE in Oil: Dissolve 4 tbsp. of the ROE in half a cup of vegetable oil. Add a quarter to one teaspoon of this dilution per 2 lbs. of oil but users have been successful using half a teaspoon per pound. Warm oil is better for prompt dilution. However, the dilution can also be refrigerated for up to 30 days and will remain at full strength The antioxidant compounds in ROE are resistant to lye; therefore, you may add the ROE to the soap batch before saponification or at trace. However, ROE is best dispersed if added to the oils at the time they are being prepared and not at trace.

    Other Uses: ROE is also used for making lotions, creams and salves. Add it in at the same proportions as used in soapmaking and add to the oil before the emulsification step for lotions. When making salves and balms, add ROE to the melted oils. Clean-Up: You will find ROE may be sticky at times. Wash all implements in warm soap & water. Precautions: Use gloves, as ROE can be a skin irritant for some people. Keep away from eyes; should it get into the eyes, flush with plenty of clean water and seek medical attention. The MSDS appears on our site in the MSDS section, top right corner of our pages.

    Per our supplier: An oleoresin is an extraction of a natural food or flavoring raw material using selected solvents to remove the vital components; the oleoresin will contain the essential oil and other important non-volatile components which enhance the flavor, act as fixative or contain other desirable properties. The solvent is removed and there is no solvent residue left in the product. The ingredients are rosemary in a vegetable oil base. Our ROE is standardized at 1.5-2.5% carnosic acid.

    INCI: Rosmarinus officinalis (Rosemary) leaf. Country of origin: U.S. Shelf life: 1.5 yrs. when properly stored.

    I only ordered a small bottle because this is the first time ordering this product here. I am very pleased! It is the best quality and strength! I have ordered from several other suppliers but this is by far the best ROE so far. It's a very important ingredient and quality makes a huge difference when using it. I highly recommend!
    This ROE is Great!

    I'm using this ROE in cold process soap. I love it! I can "superfat", and I don't have to worry about the oils going rancid. It couldn't be easier. I really like being able to add it to the soap pot in the beginning, with the oils. Which works great, as it's job is to keep the oils from oxidizing, and we are able to protect against this from the start. It does not leave a scent in the soap. It's economical, effective, and natural!!! What more could we ask for?

    I've used it in several recipes as a preservative and it has served me well. The price here is less than many other companies and the quality is excellent. ROE is VERY viscous so it's a good idea to pour it with a light hand. Also, a little goes a long way. This is a staple in my 'lab'.

    Thanks for browsing thru this section which contains answers to many questions that are often asked of us. Here we explain where to locate CofA and SDS for a product, how we dispense and package our products, how products should be stored, basic terminology and the wait time for bulk products to ship from our warehouse. FYI: We're closed on Fridays.

    Certificate of Analysis (CofA) and Safety Data Sheet (SDS). We publish on our website those documents for most of our products, some products don't provide either because the product doesn't require it. In this same section where you're at now, look to the tab to the left titled Documents, click on it and that's where you'll find either document for the product you seek. If you do not find the document you require, please email us at so we can research further.

    BULK ITEMS: When a customer adds a bulk item to the cart, the customer’s immediately shown on the screen how many number of days should be allowed for the bulk product to arrive at our warehouse. If the bulk item happens to be in stock, we’ll ship sooner than the customer would expect. As we emerge from Covid, logistics operations are not yet back to normal, what used to arrive at our warehouse in 3 days now takes much longer. Should a vendor inform us the ordered product will take longer than what’s mentioned on our website we’ll email the customer with the latest information.


    EO = essential oil

    FO = fragrance oil



    Essential oils: in 1/32 oz. to 1/4 oz...amber glass vials with orifice reducers. ½ oz. to 2 amber glass bottles with white caps and Eurodroppers...3 to 4 oz. in amber glass bottles with black caps and without orifice reducers...7 oz. in aluminum bottles...15 oz. in amber glass bottles with black caps...10 & 25 lbs. in HDPE plastic containers with wide mouths although, occasionally, 25 lbs. may be dispensed in factory-issued metal containers with pouring spouts.

    28 lbs. of carrier oils and other liquids are dispensed in individual HDPE plastic gallon containers with handles, each holds the purchased net weight of liquid.

    30+ lbs. of carrier oils, other liquids, soft butters, Castile gel and other products are dispensed in plastic HDPE pails w/metal handles & pouring spouts in the lid; those products may remain inside the pails indefinitely when properly stored. After Covid, we reserve the right to use any packaging/dispensing container available to us and not mentioned above because it continues to be difficult many times to restock the same packaging container or material used in the past.

    NOTE: An EO may safely remain inside an aluminum container for up to 3 months, but if storing longer than 3 months the oil should be transferred to amber glass. Fragrances and carrier oils up to 8 lbs. may remain inside HDPE plastic bottles indefinitely. If the customer at any time feels more comfortable transferring a product to glass this should be done. ALL PRODUCTS ARE DISPENSED BY WEIGHT, THUS, SOME CONTAINERS MAY BE FILLED HIGHER THAN OTHERS DEPENDING ON THE WEIGHT AND VISCOSITY OF EACH PRODUCT.

    Raw materials/ingredients are dispensed by weight. Many customers ask how many ounces in a pound, there are 16 ounces in one pound. These are not fluid ounces, they are ounces by weight.

    HOW TO STORE: EOs, FOs and BUTTERS should be stored in tightly-sealed containers away from direct light and heat. Some EOs could be highly flammable, keep away from open flames. Keep all liquids and powders you purchase from Camden-Grey tightly capped and away from the reach of children, the elderly or infirm and pets. Refrigerating butters could adversely affect the consistency of the butter, please join our Forum if you need to learn how to handle, work with and store products.
