Question about Oil Plug-ins

[Candle Man]

I have a customer that likes my scents over what comes in the oil plug-ins. She said the oil that comes in them lasts about 30 days. I cleaned out an empty plug-in bottle with alcohol then let dry. I then fill the bottle with 100% FO. She used it and said it only lasted 1 week.

Have any of you done this, if so, what would you mix the oil with to make it last longer?

I've tried to figure these out too. I have used straight fo, fo and DPG, fo and perfumer's alcohol. I can not get these to have as strong as scent throw as the real thing. Really, they have no scent throw at all. I gave up.

My customer says the throw is great but they just don't last very long.

If you are getting good scent throw with the FO, maybe mixing it with DPG would work for you. It is supposed to slow the evaporation rate of the FO and make it last longer. I can't tell you for sure, I've never tried it in one of those, but I do mix it with FO for sachet cards and the scent does last longer with the DPG than with straight FO. The flashpoint of DPG is about 255 degrees.

OMG, I just thought of something else, had to run and get the bottle. Ultra Pure Candle and Lamp oil is 99 percent pure liquid paraffin. I bought it to use for some oil candles. I thinking this might work! It says on the bottle it is a class IIIB combustible liquid, I just looked it up, a class IIIB has a flashpoint over 200....okay now I have to run to Walmart and get a plug in and try this...LOL!

Anybody know the exact flashpoint of liquid paraffin?
