Anything edible will also be biodegradable. Like ethanol.
The Merck Index provides information on the physical properties and toxicity of a large number of substances. Your local public (or University) library probably has a printed copy in their reference section. It is also available online
The CRC Handbook includes tables of the physical properties of a great many chemical compounds, and the company also publishes a considerable number of more specialized books. Take a look at their website. http://www.crcpress.com/
There doesn't seem to be a single source of the information you're looking for. After you've done the grunt work, you might think of publishing your results to make it easier for the next researcher.

It depends a lot on your meaning of "safe in domestic use". Vegetable oils are pretty lousy solvents for most substances. I'd start with something like dimethylacetamide, density 0.937, bp = 164-166 C, and see if this meets your definition of "safety". History: A polymer applications plant in the US used a lot of polymers dissolved in DMAc. Near-by was a noted beer brewery. Since DMAc is miscible in all proportions with water, polymers can be readily coagulated from DMAc solutions. The DMAc then can be (in some circumstances) discharged with the water runoff, or recovered. The local brewery loved the runoff, as their brewing "bugs" thrived on the DMAc in the water! One never knows how truth is stranger than fiction.
