Keep in mind that the manufacturers of FO such as Belle-Aire, Chemessence, French, Orchidia, IFT, etc............supply the FO samples to the suppliers. All of them formulate the FO's differently therefore that's why they smell different than others. The manufacturers also supply fragrance to other companies.........not just us. For ex: Belle Aire: Belle-Aire manufactures fragrances for personal care products, home fragrance products, and household and institutional/industrial cleaning products. Orchidia: Bring the Essence of Nature Into Your Environment If you produce consumer products requiring fragrances, or are simply looking for new ways to reduce unpleasant odors, Orchidia can bring the essences of nature into your environment. We employ an experienced staff of perfumers and chemists who utilize the latest technologies and old-fashioned hard work to create custom fragrances developed to meet your unique needs. IFT: Creations The targeted and talented perfumery staff at IFT, with the help of their classic training and knowledge of different aroma chemicals of natural and synthetic origin, can create your fragrances for almost any application. Duplications State-of-the-art equipment, with over 100 years of combined experience between our perfumery staff, helps us analyze any type of fragrance oils or finished products accurately and quickly. Applications Our fragrances are tested for stability in their final application: soaps, candles, lotions, etc…and when possible, directly into the customers' base. Equipment We have the latest technology in Gas Chromatography and Mass Spectrometry. Also, the industry's finest automation equipment in our production facility and sample laboratory helps us to serve our customers better and faster than any other fragrance manufacturer. Chemessence: Chemessence, Inc. has been a wholesale fragrance manufacturer since 1964. Our fragrances can be used to scent candles, potpourri, waxes, cleaning compounds and a vast variety of other applications. Also, a company like Belle-Aire can have several different versions of Hot Baked Apple Pie with different lot numbers. So yes it is very possible that the Cinnamon you get from one company is the same cinnamon somewhere else with a different name (or not). Then there are the mixed FO's. Just like you mix some to create something, so does a supplier. The suppliers aren't going to tell you where they get your fav scent............cause that's a trade secret and if you knew, you could just go directly to the manufacturer and buy the oil for much less. But also you would have to buy in a larger quantity. Sorry this is so long! But, just an explanation!
