I emailed the Splenda people about when and if liquid Splenda will be available anytime soon in the US. Here is their response. Maybe we should all send them email so they can get an idea of how much revenue it would generate for them.
Dear Carol,

Thank you for visiting the SPLENDA (R) No Calorie Sweetener website. We hope you became more familiar with SPLENDA (R) No Calorie Sweetener during your visit to the site.

Although we do not have any plans at this time to extend our product line to include a liquid version of SPLENDA (R) No Calorie Sweetener, we are always exploring potential line extensions. We are aware of the low-carb consumer base that is interested in having a liquid version of SPLENDA (R) No Calorie Sweetener available in the United States and as we plan for the future we will take this into consideration.

We hope this information is helpful, however, if you would like to learn more, you are welcome to contact us again through e-mail or call a SPLENDA (R) No Calorie Sweetener representative at 1-800-777-5363.
