I was doing a bit of research before buying some essential oils and i came across some stuff, which I thought would be helpful to keep here....though its all available there on the net
How to Buy Essential Oils
Poor quality oils (oils that have been distilled from poor crops, have been handled improperly, are old, etc.) or adulterated oils (oils that have chemicals or other oils added to them) lack the therapeutic benefit of good quality oils. Additionally essential oils that have been adulterated can cause harmful side effects, or at best provide only minimal therapeutic benefit.
Below are tips that can help you select vendors of pure, high quality essential oils:
- Watch out for words such as fragrance oil, nature identical oil, or perfume oil. These words indicate that what you see is not a pure, single essential oil. Many vendors label fragrance oils (that can be combinations of essential oils and chemicals or just plain chemicals) and perfume oils as aromatherapy. Beginners need to watch out for these vendors who inaccurately use the alternative medicine term aromatherapy for their own sales gain.
- The term pure essential oil is overused in the aromatherapy industry. Pure essential oils can be distilled from poor quality crops, be sitting in someones inventory or on a stores shelves for years, be stored in a way that damages the oils, or be mishandled by vendors so that oils are accidentally mixed during bottling. So, don't get overly impressed by a vendor that labels their oils as "pure."
- Most vendors selling quality oils at sizes of 4 oz. or smaller sell their oils in dark colored glass. Be leery of vendors that sell oils at these sizes in plastic or clear glass containers.
- When purchasing oils online, it is not uncommon for larger sizes of essential oils to be shipped in plastic containers to avoid breakage and reduce shipping fees. Essential oils, however, can dissolve plastic bottles and the quality of the oil can deteriorate more rapidly. When receiving oils shipped in plastic or clear glass, be sure to transfer the essential oils to dark colored glass bottles, unless you plan to use the essential oil up within a few days.f you purchase from a supplier that ships in plastic, ask them how long the oil has been stored in the plastic bottles prior to shipment. Ideallly, you want to work with suppliers that transfer to plastic just prior to shipment.
- Some vendors also sell larger quantities of oil in aluminum bottles. Aluminum is said to be acceptable if the inside of the bottle is lined.
- Avoid buying essential oils that have a rubber eyedropper bulb in the top because the oil can dissolve the rubber dropper and become contaminated.
- Seek out vendors that promote that they test all their oils, supply samples that you can try before you buy, and that give you confidence in their knowledge (often by providing detailed information on each oil they sell and provide other aromatherapy information that instills confidence).
- Watch out for vendors that sell all their oils for the same price. This doesnt mean the oils are not pure or of good quality, but it often does. Neroli, Jasmine and Rose, for instance, should cost a lot more than geranium and ylang ylang. A good quality patchouli usually costs more than eucalyptus. The basic citrus oils including sweet orange oils are some of the least expensive oils.
- When buying essential oils locally, watch for oils that have dust on the top of the bottles or boxes. This is an indication that the oils have been sitting around. As time passes, many oils lose their therapeutic properties, and their aroma diminishes. The bottles should be sealed so that the oil couldn't be contaminated by other cutomers. Be sure they have tester bottles of the EOs so that you can sample the oils.
- Organic oils are typically superior to non-organic oils.
- Be careful when buying essential oils from companies that primarily sell to the food & beverage or perfumery industries. Some vendors that primarily sell to these industries may have different goals in the purchase and sale of their essential oils than the goals of vendors that sell therapeutic-grade oils specifically for aromatherapy use. The restaurant and perfumery industries desire essential oils that have a standardized (consistent) aroma or flavor. The oils sold by these sources may be redistilled to remove or add specific constituents (natural chemicals found in the oils). These re-distillations or adulterations may harm the therapeutic use of the oils. If desiring to buy from such a vendor, inquire first to ask about their methods.
- Most of us need to watch how much we spend. Its very tempting to buy essential oils from the companies that sell them for the lowest price. Price alone isnt an indication of quality, but it can be. Knowledgeable vendors that spend countless hours locating quality oils, pay the expensive fees to test their oils and provide free samples upon request should rightfully be charging more for their oils than retailers that stock oils that theyve sourced from the cheapest sources.
here r few websites which seem to meet the above criteria or are recommended by someone. this is just a quick research please get samples or do more research before buying large quantities
