We now have DPG! Are you making one of the fabulous diffuser reed bottles? DPG mixed with your fragrance oil will slow the evaporation of the fragrance so the scent lasts longer. Straight fragrance oil may last only a month or two (depending on how much is added to the bottle) but DPG can slow the rate of evaporation so your scent may last 6 months or more.
For diffuser bottle people we recommend mixing DPG at 2 fl oz and fragrance oil at 2 fl oz into a 4 fl oz Amber Glass Bottle. Then ask your customers to add the mixture to their diffuser bottle when they get home. We like the apothecary bottle to have between 2 and 3 fl oz of scent mixture when we set the reeds inside. Please remind your customers that if they have been using an Almond scent in their diffuser bottles and now want Strawberry the reeds should be replaced. Similar fragrances do not need replacement of the reeds when changing scents.
And a few soapmakers have asked us to get DPG to help accelerate the trace of their soap (yes, they really do want it for that) so the slow batches can be sped up a bit. A little goes a long way!
