Which substance has melting point around +38-+43 Centigrades? A substance should be completely non toxic even if ingested. For example, something that could be used in a food industry. In its solid form (over +45C) it should be relatively hard, not too plastic.

I sounds to me like you are attempting to create something.

See Wikipedia, Phase Change Material, Thermophysical Properties. The list includes many outside your temperature range and a few within it. You will have to investigate toxicity. Some paraffin melts in your temperature range and has low toxicity, but it is flammable.

Cesium. Some waxes (paraffin). Also some chocolates.

Not cesium then. Possibly chocolate, though. Also still possibly wax.

Phase changes don't work like that. If the melting point is 40ºC, it will not be solid at 45ºC

Ear wax? 45^oC

Candlewax is 37^oC

Sealing wax is 45^oC

I don't understand, how can it be hard at 45^oC if its melting point is 38^oC?

He probably misspell, and meant 35 C, instead of 45 C.

Some fats (triglycerides) melt around +40°C, which makes them bad for cholesterine though edible. Most natural fats are mixes, so their melting point is ill-defined. Among the components of palm oil, you'll find some.
