As you all know, E0's can be very harsh on plastics. When buying lab equipment, what plastics should and should not be used? I use a dispenser to fill bottles. I need to be concerned about parts like tubing, nozzels, diaphrams and filters.

Other than the cloudiness issue, this seems like a popular emulsifier. Mostly I read that you can use it 1:1. Some people suggest using more. I have made tests 1:1 and 2:1 (twice as much PS to FO) and it does not seem to make much difference (to me). I am wondering if using 2:1 would have more holding power. Or, would using too much put it on the road of diminishing returns? By "holding power" I mean to stay in a state emulsion longer. Does PS20 have a tendency to separate? I can write "shake well before each use" on the label and while that will protect me, most consumers are not likely to follow instructions. It's only human.

I am looking for a room spray base in which the finished product will be clear (or slightly yellow) and will hold as much FO as possible. AH/RE has a Fragrance Room & Body Spray that they say will hold 8 or 9% FO. They also have a Moisturizing Spray Base that will hold a lot. Is there anything around that will beat that? I also ordered some CME from Lotion Crafter and will try that. Anyone know how much FO can be loaded into that at the maximum?

I want to make tester bottles of my FO's. If you leave them in liquid form, customers might spill it in the store. Is there a way to gel it without using heat? Or, a way of scenting pellets?

I am looking for electric diffusers that are filled with water and FO and spray a mist into the air. I think they work with sonic waves.

I am looking for both plastic and wood displays. I would like the type with tester bottles in the front and the bottles to be sold behind them. These can be put on shelves or counter displays.

I just realized there are a number of threads on this subject. Great board.

I realize it must vary from fragrance oil to fragrance oil, but what sort of shelf life can one expect?

Where the wax go when it melts? Into the air? What about the soy oil in the fragrance? Into the air? As to 001's comment, sure hope you are right.

There is a disease called oil pneumonia or lipoid pneumonia which is caused by inhaling oils such as mineral oil or castor oil. But I have also seen veg. oil included in the list of causes. When we burn candles with soybean oil based FOs, aren't we inhaling soybean oil?

Thanks for the feedback Stella but there are some points that need fine-tuning. I think you are wrong when you say "always no" to oils being water soluble. DEP, PG, and glycerin, for example, are water soluble oils. So is ethanol, which is often used as a carrier or solvent in fragrance and flavoring. In another thread, I indicated that I wanted to know what solvents FO's are based on and was told that it is proprietary and that no manufacture would tell me. That is one reason I would like to use flavoring as manufacturers are required by the FDA to tell you. Usually flavoring is based on one or more of the following solvents: PG, glycerin, soy oil, ethanol, and/or water. Soy oil would not be water soluble but the others are. I want to use FO's (or flavoring) in ultrasonic diffusers. Why do you suggest flavoring for lip balm but not scenting. Many of the molecules used in flavoring are the same as those used in FO's. It is just not FDA approved. In fact, some perfumists use favoring in their formulations. I would like to use flavoring as the manufacturers are more transparent as to what the flavoring contains. Flavoring must never contain DPG but they could be diluted with DPG for use as a fragrance. Is there any reason flavoring could not be used as fragrance?
